Interesting he designed the backbone chassis with CAD and built it.
Started out as being a hill climb car, but looks like now the build is coming along its going to be an amazing RX-8 engined road car :bravo_2: .

Thanks for posting the pics Clive. If anyone has any questions on the build just ping me a line, I'm happy to share my experiences, successes, failures etc.
It's an Elan +2 ...... Lots to do, just making a pattern for a one off fibreglass dashboard ATM..... about to start the fuel tank fabrication soon, wish me luck ......

Yes the intention was track days after I was refused a national b licence on medical grounds, as I was going to do hill climbs, with a view to use this car in the sports libre class after I got a few years under my belt.
But, with track days you get more time than a 1 minute run up the hill twice a day......
Bit new to all the forum stuff so I'll post some pics when I find my way around the site, the build has advanced a little since the other pics, so keep tuned.
Question while I'm here, I've been speaking to Clive the other week on fuel pumps, filters etc.
I've ordered all the aluminium sheet today to build my tank and Clive had mentioned 8mm tails on the pump, so here goes with a few questions if anyone can help?.....
1. On the outlet and return, with 8mm tails, is that o.d. Or I.d.
2. Will push fit fuel hose suffice for the pressures of fuel injection or should I be using JIC -6 fittings?
3. I want to retain the stock rx8 instrument panel, the stock tank uses 2 X fuel senders, I was intending on buying a universal sender, but the ohms need to match the clocks, looking on the manual, the stock sender is 9 ohms when full and around 322 ohms when empty. I could possibly get a sender in that range, but if I use 1 instead of the 2 in the stock set up, is something likely to get confused?.. I don't really want to add an aftermarket fuel gauge.....
Any help is greatly appreciated...
Oh, and while there's no glass in I use the overhead crane lol it's still light, even with the newly fitted integral roll cage. I gave a pit, but when I'm going to be working on the new wings, I want the car at a decent working height 😆
Post by: boosted on December 02, 2018, 06:58:51 PM
The rx8 runs a returnless fuel system so unless intending to use a swirl pot not needed.
That said i cant run my westy below 1/4 of a tank else i get fuel cut in the corners so best practice baffle your tank or incorporate a swirl pot within? Ive added a fuel filter a systec 1 within my engine bay the rx8 fuel pot houses a filter inside it that can block over time...it all depends what you decide to run..
I didnt manage to get the fuel system to work on 1 sender..Paul on here has in his 8 converted mx5...worth reading his thread and asking him.

Oil starvation...oil moves up the fill tube away from the pick up pipe on hard right handers...best to fit a sump baffle or gated sump and a catch tank....i also dumped the omp. Its stilll on car blindly working but it does not inject 2t oil.
This allows me to run 5w40 fully synthethic oil and so far so good.
My car was for racing but i got demoralised being in the top class with a 1300 lol so trackdays it is for me.

Lotus didn't have the best reputation for reliability, but Colin Chapman, was a clever man back in the day.
Lots of individuals have slated me for "ruining" a traditional British sport scar.
My take on it is, everything can be improved upon, and following Colin Chapman's mind-set back in the day of pulling stuff out of parts bins and making them work. I'm sure if he was still alive today he too would use a rotary power plant as he was all for lightweight vehicles over huge HP.
I'm aiming for around 700-800 Kgs all in. I still have lots of lightening to do, even though its fibreglass, the doors feature 1960's technology of electric windows and each door weighs as much as a nuclear power station....... its ridiculous!
The reason I choose a Lotus Elan was it was my ex bosses car, I got the complete car for £1000, and to be fair, it was in a sorry state, I bought a non running RX8 for £700. Weirdly, im not sure if its the colour, but the lines and the stance reminded me of the Mazda 110 Cosmo, cogs started whirring and I decided to amalgamate the 2.

If you revert to the pic with the intake, you'll see a shot of a aluminium 90 degree bend.
On either end of that bend there's a silicone coupler with a bellow in it, there's both the sieve mesh thingys installed either end of the 90 bend inside the bellow, I pulled the other mesh out of the air box and tried to keep them as close to the original distance apart as the stock set up.
But really appreciate the heads up :13:

Post by: boosted on December 03, 2018, 06:09:15 PM
Mine house the rx8 fuelpot into the tank albeit with a longer body to scavenge from the bottom of the tank. So it is returnless but no issue having an engine bay fpr and running a return...think about a swirlpot. Rotaries are thirsty and i have a 25l tank that i pretty much have to refill at 8l else i risk fuel cut in corners...which on a lightweight car is enough to lock the rear wheels up!!!!

Makes more room too, the engine bay is tight.
Pics of the tank below.
designed to fit above the diff between the rear wheels and mounted on the roll cage cross bar behind the seats.
Natural taper of the car body allows fuel to drain to the "sump"
Tank capacity is 85 litres, sump capacity is 1.5 litres
Outlet to the in line pump is at the bottom of the sump, return pipe feeds back into the sump through the "drain hole", the thought process was making an in tank swirl pot. The sump is always full of fuel, by gravity from the main tank and the return line from the FPR (get me!!)
At 1.5 litres it probably wont need anymore baffles, I doubt much fuel will escape back out the 25mm "drain hole"
Ive left all the internal baffles in the main tank at this stage but will probably be a huge X baffle from corner to corner with some gates or holes in certain place.
Thoughts?

Previous variants were 58 litres and 46 litres.
Decided to make it fill up the area behind the seats,
May have more room for the standard fuel level senders albeit leant over a bit.
Yeah, it's a bit pricey, but looking on the bright side, the tank is low, and it's putting the weight in the middle of the car.
Hoping to fit the pump and filter underneath behind the drivers seat, and the battery on t'other side under the tank.
Enough about me, gonna have a peek at the westy.......

For a small engine, its still tall with all the air intake and oil filler neck.
Ive had to make a few incisions in my stock bonnet to get it to close, more fibreglassing ahead!
Thankfully my sump is 5mm up from any chassis rails. I set the suspension pick up points on the chassis so I can run a 5" ride height on the underside of the chassis to the floor without all the arms pointing at stupid angles and upsetting the handling. If possible I want this car road legal so need to consider speed humps and pot holes down my road.
That's a 1" drop from the standard lotus, so everything moves up inside the car and the roof is only 47" off the floor.... GT47 ??? nah
Bit of a squeeze for a tubby like me hahaha
Im planning on running a full front to back underfloor diffuser to try and get a bit more suck down at speeds, but that will be trial and error once its running.

You mentioned losing the air pump which is fine, I had relocated it, and modified pieces on the valve for more clearance on the headers.
That's not an issue I bought a stainless exhaust manifold flange from Clive earlier this year and can blank the hole up.
Looking through the manuals, I've noticed ancillary parts like on the pics below, charcoal canisters and some EVAP doo dahs that if I remember correctly sat under the boot floor high up above the diff.
Can this be junked as well?
Ive ruled everything in at this stage so I can rule it out, like my Decat pipe, I can run the standard Cat in the engine bay (pic attached) between the engine and bulkhead, it bolts to the bellhousing and thought just in case Mr. MOT inspector wanted it, its 7 bolts to swap it out.
If you can think of other stuff I can junk, just shout ..........

I have no cat as car is a Q plate! Emmisions exempt booyar! I also got it sucessfully registered as a 1300cc so cheaper tax. 3 attempt with dvla mind.
Id considered wrapping the exhaust crossover pipe...its gonna get very very hot...ive burnt my leg several times on mine!
I think with a cat in that place you could probably melt the intake....serious heat and noise is rotary!
Mine tests static noise test between 92 and 94dB with a 9" repackable silencer from Torque Techniques in Salisbury...its not got any louder...he said quote" argghh Rotary i know what cloth to use from my Janspeed days" ..silencers been great.

Im not fussed about the loops holes of the system, if I get stung, Ill have a track day weapon, just trailer it everywhere.
Whats your view on the decat pipe? (pic further up the post) I have no room anywhere else for an exhaust without chopping my legs off, the front wheel axle line on your westy is a bit further forward than my set up so your headers come straight out the side and I cant move my engine back any further.
I did plan on ceramic coating the hole engine bay with that sticky backed stuff, wrapping the exhaust although I think it looks hideous and having serious vents in the bonnet to let the air out.
Was trying to get clever with bonnet design and drawing radiator air out the front of the bonnet and another inlet and outlet to allow incoming air to draw the hot air of the exhaust out. Bit like that vent you have behind your air filter on the westy.
Ive seen plenty of videos on the web of glowing red exhausts on 8's and 7's so I thought with the location of the cat or the decat pipe its like a windscreen de-icer for the winter lol.
Post by: boosted on December 04, 2018, 03:03:59 PM
The specialist coating zircotec would be awesome but doing the manifold and decat pipe would be alot of dosh i think but would be epic in controlling the heat. I know the wrap is unsightly but it does work. I think braided fuel hose in the engine compartment would be safe choice.
Youve got to work with what room youve got and the manifold is ace, nice flowing bends and big bore so should be fine, just the heat to deal with.
where the steering column on your car? I have to remove mine pulling/fitting engine? as inlet and manifold over under it.
Post by: Jamie R on December 04, 2018, 03:13:24 PM
2 headers loop under the column, 1 loops over it.
No decent pics of it yet.
Ive got pie cut exhaust headers all the way up to the collector, some parts are only tacked and there are only tacks on the manifold flange.
Cant finish it till the engine comes out.
Back to the column......that will be heat shielded too,
Post by: re japi on December 04, 2018, 03:27:41 PM
Also, you need to figure out how to get maximum air flow to radiator and oil cooler(s). Rotarys are really sensitive about those. Water cools about 70% from engine massive heat, and oil cools rest. Howerer, in rotary oil needs to be really good and in good temp...

There was talk of unequal length is best to accomodate the exhaust pulses but at 5000 to 9000 rpms thats 1 hell of lot of pulses and unequal or not there gonna collide at the collector unless your a maths genuis ...my take would be you got to work with what space youve got and try and make it as free flowing as possible, which i believe mine does. The stock rx8 manifold is a brick wall for gas flow but Mazda had to work with the space they had.

Post by: Jamie R on December 04, 2018, 03:44:00 PM
I've had opposite feedback about the headers on the RX8 because of the side port and its not as sensitive as the RX7 with peripheral ports.
I've designed and built a few expansion chambers for 2 stroke bikes, and yes I take on board your point.
Look at the standard RX8 manifold, its rubbish, the front port exhaust gas has to travel much further as a percentage compared to the rear port before it gets to the cat.
I emailed Racing beat in America, and they said they had run several different options on header length and when dyno'd made little difference because of the side port and you don't get the same benefit from the "pulse"
So from experiences, I've made the exhaust headers long enough to make them work practically and a lot of people in the 4 stroke world like "equal length headers" but some are as much as 10" difference in length. I've managed to keep all 3 headers with 100mm of one another just to balance things out as near as I could.
And yes I've heard that too about the oil coolers. I've stuck with the stock ones as Im only going for a Bridgeport and an Adaptronic ECU in terms of tuning, so im happy around the 280 Bhp mark if possible.
The bumper will be custom made in fibreglass too, and will probably resemble a fish with a gaping mouth LOL. I don't have any constraints in terms of air flow into the radiators, but more about room getting the air out, which is equally important.
I do appreciate the feedback though, its good to share stuff as it leads to good ideas. :13:

Howerer, theres much tests and tips how rotary headers for Peripheral exhaust should be made. One key tip is that first you go with straight pipe for 5cm and only after that can first curve begin. Also, there is few best choise of header leghts. But what I have found out, many will build too restrictin collector...
Im sure that Hayward knows best lengts for Renny headers. But I think aftermarket like RBs are really good too

Beautiful pipe craft but please lose the cat, but if you really want one in the system a smaller outside diameter Hi-Flow cat could be used to get the pipework away from the inlet.
As you would know super heating the inlet mixture is never good as you always need the opposite, i.e. a cold dense mixture. Although expensive, Zicotech plasma spray coating will solve this for the manifold plus keep the engine bay cool.
Amazing stuff, even on the race cars turbo straight after a race you could put your hand virtually on the hot side of the turbo!

Thought id ping some pics of the dash.
Retaining the stock instrument panel, but its being located in the centre like Minis. The bulkhead / dash on the Lotus in relation to the windscreen is very different from the RX8, hence I could fit the CAT behind the engine.......
....anyhoo, bored of exhausts for a while, we've done that to death.
I've made a "buck" or "pattern" from plywood, polystyrene, filler, wattle n daub, chicken wire, mud, dung, pig iron and anything else that I had lay around....
Next is to lay some fibreglass over it to make a mould, then ill be cast my own dash and hope that the clocks and glove box still fits.
Ignore the finish of the grey primer, its "brushed" trowelled on its some cystic primer stuff that you mix with catalyst to harden it. its all been blocked down now but don't have any pics of that.

I need to make 4 new wings / arches to house the wheels.
Im going to run 17 x 7 steel wheels off a Hyundai Santa Fe (I think) which I purchased from some discount wheel website at £80 each. ( Im not sure if Im allowed to mention other companies on here, don't want Clive telling the newbie off lol)
They have the same offset, PCD and centre bore as the 17 x7 Alloys fitted to some RX8's. I don't know if some models had smaller brakes, but because I bought steel wheels, I have loads of clearance for the 231 bhp brakes and calipers.
Plus they are more in keeping with the original style of the car.
Ive altered the wheelbase front to back.
Because of the much larger wheels Ive increased the wheel base by 50mm over stock Lotus, so I didn't need to cut up the inner arches where my feet and pedals would be.
That said, even with the increase in wheel base, its still 100mm shorter than a stock RX8. So should be more responsive on turning into bends.
The pic below shows a CAD image of the original lotus chassis which I needed as a datum before I modelled up the new one, I needed to make sure the body would fit on the new chassis with minimal cutting to the shell.
The green wheels on the image are the original lotus ones in the correct position and the grey ones are the 18 x 8 from the RX8.
From that I can move all the suspension pick up points further up into the chassis as the centre of the wheel is further from the floor on the new wheels, and I was also able to lower the car without upsetting the suspension geometry.

Yes, I still have a passion for classic fords and yeah, identical bellhousing patterns does make engine and gearbox swaps easier.
I'll hopefully have another Anglia 105e one day, maybe even rotary powered.
But when Ive finished the Elan, I have another 2 motorbikes and a Morgan 3 wheeler replica to build........

Easier to start from scratch with a new backbone chassis than trying to graft RX8 stuff on the Lotus chassis.
Handy for taking dimensions from it though :great:

I also wish I had the balls to do this sort of thing for a living, but everyone says theres no money unless your name is Richard Rawlings, Boyd Coddington, or Dave Kindig.
So Ill settle for going semi retired and have this as a working hobby.............I probably wouldnt enjoy it so much.

Tacked the basic shape today and brought it home for trial fit
By Christ! it only fits! more luck than judgment, and room for the harnesses to strap on the rear of the cage.
Lots of welding this weekend.
Anyone recommend the best way to mount it???
Strap it down with metal bands, or weld L brackets to the outside and bolt it solidly to the cage??
Oh and any recommendations for a small battery that will power all the electrics including lights with decent cranking Amps.
Im going to house it under the tank on passenger side
Thanks in advance for any input :13:

If I'm honest I forgot to look,
The little bracket at the bottom of the rank is to house the 2 stock senders.
I've cut 2 squares out the bottom of the stock plastic tank and bolt them to the Ali bracket, the stock senders will click into place.
The full level position on the stock tank is higher than my tank so I've canted them over a little bit,
I'll do a bit of wiring wizardry, well good for me so both sets of wires join the same block connector ;)
The more things I can keep stock the more chance I got to make it work hahaha

I can do the physical side of it like making looms, push fit block connectors etc.
I just can't get my head around the theory.
So I've not go that far but here's a quick run down
Abs sensors removed because I'm running bias pedal box,
No air con,
No airbags,
No alarm, no central locking
No stereo
Adaptronic ecu from Clive when I get it.
Stock accelerator fly by wire
Aftermarket fuel pump
Then there's all the other stuff from lotus that I need to graft into a rx8 loom
Lotus heater control,
Lotus wiper motor, which is used to 2 speeds and the rx8 stalk gas more functions along with squirters.
The fact it's a fibreglass body so no so easy to find an earth like screwing a wire terminal into the body
The list is endless .......

Bit rusty on the old ali welding..........that's such a contradiction !! lollllll
Its staying now.
So its all welded up, just the outlet and the return line fittings to weld in.
No its not a fat aerial, lol, I welded in the filler pipe extra long so I can trim it to length, but capped it off and put a tyre shreader valve in the end so I can pressure test it :)
....... bet it leaks hahahaha

Just wondered if you were running the stock accelerator pedal with fly by wire in your westy?
I'm eyeing up bias pedal boxes with a view to removing the accelerator pedal as it cable operated.
Downside is they are floor mounted and the accelerator is top hung.........
Cheers

I found obp to be cheaper tbh, oh and the fly by wire pedal boxes are ridiculously priced,
I'll settle for the ergonomics of floor mounted brakes and top hung accelerator like you have considering it all works.
I did consider converting the stock accelerator pedal in to a shortened lever operated by a Bowden cable with a traditional accelerator pedal, but seemed like making work for the sake of it.
Thanks Jon

I can't seem to find tilton boxes, with cockpit mounted master cylinders, I need them pointed towards me because my roll cage will get in the way,
That way I can put my heel board over them, and as the father in law wants to have a play on the track too I'm making the pedal box adjustable coz he has diddy legs lol.
I think the obp are about 380 something with the bias adjustable cable, the cylinders and the reservoirs...... The link I sent you was a package with the braided lines, but I'll make my own coz I don't know where I'm mounting the reservoirs yet, I can't believe 3 braided lines are 140 quid !!
Anyhow, I pressure tested the tank tonight, 5 leaks......
One pin hole on the undeside.....got sloppy, after 4.5 metres of weld I can deal with 1 pin hole given my limited experience...
3 pin holes around the filler neck, ouch, I'm putting it down to different grades of aluminium, but either or, I've cured them .....
I have a major one around the white plastic fuel pot top..... I noticed on your you tube vid you used some black "jollop" around it.
I've got a 5mm thick flanges welded to the underside of the tank, a homemade viton gasket, the white plastic piece then another 5mm Ali ring clamping it all together,
I think it's coming through the bolt holes, I used 10 bolts........I just wondered what you used to seal your tank? I roof some roof and gutter sealant tonight because it didn't say you can't use it with petrol lol
Didn't know whether you used a polyurethane sealant or something ..................

Got the tank in place, pressure tested, slight change of plans for the fuel filler neck because some dozy twonk welded a roll cage in the way and didn't check the location.......
Never claimed to be perfect lol.....
Anyway, I'm struggling to find a suitable location for the filler cap, tried mounting it in the boot area, like the mk1 escort rally cars, but can't get enough height without having the pipe horizontal ....hmmmmmmm
The original location for the filler cap is a no go for the same reason....., the original tank had the fuel entry half way up the tank so I envisage the filling processs long and laborious....
I can cut a new hole in the car no problem, but before I do.....
Can the filler cap be positioned inside the cabin, next to the drivers seat????
Are any production cars from back in the day with a similar set up?
Are there any restrictions on this from a track day perspective / safety requirements?
I know it may look odd opening the drivers Dood on the petrol forecourt....
The cap is non vented and I'm running a separate vent pipe outside the car......
Appreciate any guidance, even if it just calling me a **** for putting the roll cage in the way

I wish it was that simple, or maybe im over complicating things......
Anyway its been playing on my mind all night, I got up at stupid o'clock to take pics to show you what im up against.
A - possible new locations, shown, I can enlarge the existing aerial hole or fill it up and cut a new one. I prefer the higher position though.
B - See the entry point for fuel, I've capped off the previous location - but more importantly whatever I do, Im going to need to get the tank in and out at certain points.
C -Cant use the existing filler cap location, because of my plans for the new wings.
D - Shows the gap between the rollcage rear strut brace and the underside of the boot rain gutter
E - Flexi Pipe pointing to the drivers side which could be fed by previous 2 location suggestions, if it was longer..........
F - Prefer the look of the new cap, and Im not opposed to the location,
G - Plenty of room, and a decent "fall" for the fuel into the tank.
H - Was thinking here ???? As an alternative, and clean up the outside appearance rather than filler caps on show.
J- Yes I missed "I" ..... anyway, a method of electrical tape, it may work, stronger than my welds haha, but going off your suggestion Jon.
..........need another post!

Post by: Jamie R on December 20, 2018, 07:50:21 AM
Anyhoo, last couple..
K - I can extend the pipe, but ergonomically it feels weird reaching in, putting the forecourt nozzle and 3 metres of pipe in the boot lol, and ....... it sits too horizontally, and as you can see I cant go up further without making everything else worse...
L - tried the same idea with the flexi pipe, but because the boot slopes down the further back, the lower it needs to be, then the fuel ends up in the boot.
I could pop the filler cap out the top of the boot like a blower on the bonnet of a hot rod and make a feature of it.......
What would you do Jon, please don't say buy a different car hahaha
Post by: Jamie R on December 20, 2018, 10:52:11 AM
With hindsight, what I should have done was make the tank and leave all the holes out of it.
Mock it up in the car, then plan properly where everything should route.
I went the other way because I didn't want to have to cut new holes in a sealed tank and have dust a swarf floating about inside.
Oh well, it was my first fuel tank, lessons learned, everyday is an education as they say .

back to tank...um i think youve gotta use existing filler hole and change the orientation of the tank inlet so it works so yep tank has to come out.
I think ive had my fuel pot out 50 to 60 times in early days getting it right so sometimes is just trial and error. :dontknow:
i ve got a spare filler neck minus cap if any help to you i had to buy another as lost the cap at a filling station when i forgot to put on in my excitement.

I have a solution.

some loverly fab skills 8) and very interesting build any thought on the top coat colour :great:
Thanks for the kind words folks........ Seriously tho, I just wing it, there's no science behind it..... Apart from the equation on the board to make a cardboard template lol.
Mr. Exiled Viking.... That ole bean is the million dollar question.
Besides the fact the car is heavily modified, and will have new wings, big wheels, new bumper, under boot diffuser, in my head it will look period as much as it can, you should still be able to look at it and tell what it is........ An Elan on steroids. One of the reasons I went for 7x17 steel wheels.
Colour is am important part, but I haven't decided yet. I'm open to suggestions from everyone who wants to chip in. It needs to look like its from the era so no pearls, or funky metallics.
So ideas so far......
I really like ermine white like it is, like the mk1 and mk2 lotus cortinas and escort twin cam back in the day.
But with a satin black bonnet and satin black bumpers and wheels and lose all the bright work. (Chrome goes rusty and is stupidly priced)
When my car left the factory it was British racing green, so I'm thinking going back to its roots with a yellow stripe right down the middle of the car with the yellow widening around the radiator intake hole.........
Guys, it's an open forum, give me some inspiration...........

Hahahaha Jarno ! I admire your honesty :13: I guess colour is a personal taste. Yes the Red Miata, is a nice colour, theres a guy at the Shelsley Walsh hillclimb who has one.
I posted a few pics below.... I know this forum isnt for any old car, but as an example my 1947 Chevy Truck was painted in gloss beige from the 1980's Volvo 240 of all things, with satin maroon to break it up.
Jon theres a standard lotus blue which looks similar to your aurora blue.
As much as I like the 787 Le Mans livery, (reminds me of a box of Tic Tacs) I think i need to stay true to what the car is, a 70's British car.
The white with the black roof and blacked out bumpers etc.........drool !
Anyway, back to fibreglass a dash board mould........ Christmas Eve in the shed at 6am, woot !
p.s. see the recessed filler cap on the truck...... :P :P theres a bit of a theme going on.

Merry Christmas all. My two penneth is one of your original thoughts , British Racing Green with the Yellow or another favourite was I believe called Bristol Racing Blue??? but can find no evidence to support this other than I had a Ford Consul Classic resprayed in this colour back in the 60's.
Yeah, Im struggling to find a more "fitting" colour......... but plenty of time to draw a conclusion.
So ive been busy over the holiday period making my first multi part mould for the dashboard.
Needs tidying up and flatting back in places and the gel coat has chipped but no major dramas that cant be rectified.
Had to bash the pattern to get the mould off, but it was a disposable item anyway.......
Will post the finished dashboard in the new year......... long hot tub weekend away with the better half as shes been a "shed widow" most of December.

There's no immediate rush, I'm on holibobs in Devon ATM.
I've emailed Clive on the rbe website to see if I can get a price for the instrument panel without the water temp gauge and the ashtray mount......
Been on the bay of "E" and there are some discounted items there, but unsure of the quality.......
You get what you pay for I guess
Appreciate the support tho... :icon_thumleft: :icon_thumleft:
Post by: boosted on December 31, 2018, 01:50:37 PM
anyways. RB sandwich from Clive 2 ports i believe 1/8 npt. oil pressure 0 to 150psi. oil temp 0-150 C..
quality branded gauges should be fine.
As your going on track id get a pressure gauge with a low limit warning...a bright light is easier to detect at speed than a needle on a gauge.
Due to your weight, sticky tyres etc i suspect you could fall into my category of oil starvation in corners on track...2 engines later....lol..baffle that sump!!! set low limit warning to 30psi so will be on at idle. ...and have you fitted a uprated oil press reg in sump? Clives got them in stock.
If your using the stock oil coolers these have oil bypass thermostats in there so oil will get up to temp quickly...max 110 deg C Oil is used for cooling in Rotarys. need a Coolant Gauge ideally too....
Another option is a Digi Dash...I use a BJR...cheaper than gauges. :13:
Post by: Jamie R on December 31, 2018, 04:59:59 PM
I have a few things to buy from Clive in the new year so ill get a sandwich plate, i think the one hole is 3/8 NPT but plenty of senders about.
Noted on the range and warning light.
Ive not done anything yet to the engine apart from exhaust manifold and braided oil cooler lines coz stock ones didnt fit.
If you have any info on baffling the sump ill do that and get a oil pressure regulator from clive.
I like the digi dashes like SPA and stack, but think they are more suited to your westy, ill stick with analogue lol....
Is the stock water temp gauge no good?

So! come to fit the parts, there was some movement during bolting the mould together and laying up the glass.
The glove box and dashboard gaps were really annoying me, yeah I know its just a glove box, but a passenger will notice it!
So I carved a massive section out and reglassed it.
Just finished fitting it up.
Bit pi**ed off with it now, need to move onto something different like the centre console and integrating oil temp/pressure gauges and heater controls. Need to cover up the mounting bolts under the clocks.................
The paint and flocking can waiting till final fit up.
I may have launched the dash out the shed if it wasnt gonna play ball! :angry5: :angry5: :angryfire: :angryfire: :violent1:
Like the clocks coming into contact with the heater !!

Well, the honest answer is two-fold. The original purpose of the car was for it to be road legal, so, you know how it is when women need somewhere to put their designer glasses lol (Not being sexist, just factual)
Plus the fuses/relays/ecu/alarm boxes from the RX8 engine bay wont fit in the lotus engine bay, so I was gonna tuck them both high up on the passenger side bulk head.
The glove box hides a multitude of sins and by "popping" it out Ive got good access
No other reason......

They are indeed...........exciting times!
They are certainly shinier than the new pattern for the fibreglass centre console.
Its still early days and looking very ugly, made from part of the original and chopped out bits added, drywall adhesive, wood, and boat loads of filler.
The oil pressure / temp gauge will be grafted onto this too.
Its an obscure shape, but it makes sense when it marrys up with the dashboard.
Off to the Middle East on Friday so progress will be slow for a week or two..........
Clive...... I have a couple of Q? on the new parts, can I give you a tinkle tomorrow if youre in the office?
Post by: clive on January 30, 2019, 08:16:48 PM
I suspect you may ask if you need a return line ?
When I ordered the FPR, I was told that whilst the RX-8 is classed as a return less system a return pipe needs to be plumbed back into the bottom port on the FPR.
Jon, can you help Jamie with some pictures as you are running the same type of fuel system setup ?
Malcolm, it would help if you could take some pictures of the fuel pipes where they meet the bulkhead to show the colours of the fuel connectors as this should also help Jamie know what pipes go where. From memory your looking at red and blue connectors.

That packaging was stronger than my welding !!!
Nope the return line isn't an issue, but any help Jon and Malcolm can give would certainly be welcomed.........I'm asuuming the regulator is set at the correct pressure and its "non adjustable" ?
It was more about the tails on the pump you emailed about and the extra one taped to the outside of the box, it's only a quickie, I'll buzz you tomorrow.
Post by: Casey on January 30, 2019, 09:43:11 PM
Are you using that new Walbro pump in an RX-8 fuel basket? If so, that's the same as I'm currently running. Not sure if you are aware that the recommendation is to melt the plastic around the top of the pop-off valve on the basket, to prevent the higher pressure pump activating it. Done it on mine and never had an issue.

Im in need of some advice......marry, kill, or bury in the back yard alive.................. joking!
From a servicing, longevity, safety, yadda yadda perspective......
Need to find a location for mounting fuel pump and filter.
Options are 1, inside the car, near the sump and outlet of the fuel tank. Fuel lines run inside the car also.
or 2, in the same location under the car. The original rear seat squab of the previous location provides a void, so pump and filter sit above the scrub line of the car and therefore cannot come into contact with anything. Fuel lines would run inside the transmission tunnel clipped to the box section.
Photos attached for clarity, I can see pros and cons for both, but would appreciate experiences from all walks, either road, track or race car owners.
Cheers in advance.

God forbid you turn it over then fuel will run out vent pipe spilling all over ground around car....then possible catch on fire....very 70s race car :13: depending on where your vent connection is on your tank hard braking acceleration or corning can force fuel up the line and out whilst on the move....
https://www.merlinmotorsport.co.uk/s/fuel-system/tank-breather-valve-and-roll-over-valves i bought the 2nd 1 in Top Left as had 8mm vent piping.
various prices and fittings.... :) i had it happen to me at combe i came out of camp and down towards start/finish straight depositing all my fuel over back tyres....luckily a keen eye marshall spotted it god knows how and i was black flagged !
I had to go into Merlin and buy the bits and make trackside mods.... :violent1:
mine: 8mm fuel hose from tank vent hosetail upto top of cage. Roll over valve vent inserted just before top monted vertically a sper destructions. Return down rollbar under bodywork but over axle and ran out the back off the car so vents behind wheels. fitted some 4 years ago no issues since.
Post by: Jamie R on February 11, 2019, 10:42:31 AM
As the for the pump and filter location? under floor, over floor wombling free?
Inside the car Ive gotta pull the seats out.
Under the car, I can see anything dripping, but I have a pit I can use.
Just whether its gonna get covered in crap.
Don't really want high pressure fuel leaks inside. I suppose a firewall will be next on the cards.

Me and the father in law cooked up the same theory.
The underside of the car will have a full length aluminium diffuser to try and generate some "suck down" at the back as I don't want to ruin the lines of the car with a spoiler.
This potentially will cover the pump and filter.
I suppose the only with Q is, (which I would appreciate your or anyone view is) do I run 8mm bore rubber fuel hose or try and utilise the original metal pipes and re shape to suit.
Maybe im over-thinking stuff again, just thinking, hot - cold temperatures rubber perishing etc.

Umm, what regulation roll gage is that? No door bars?
Post by: Jamie R on February 21, 2019, 07:10:44 AM
I downloaded a copy of the MSA blue book and adopted as many principles from the regs as possible.
A basic cage doesn't require door bars from my understanding.
And besides which, top of the roof is 47 inches off the floor and I tip the scales at 118kg. It's a tight squeeze now, I'd never get in or out with door bars haha need a diet before race day lol.
My main reason for the cage was for added stiffness between the body and chassis. I can still unbolt the body from the chassis, but the cage is now a permanent fixture. It's bolted to the steel sill members, eventually I will glass the a pillars around the cage for a bit more rigidity as they are cracked in places where the rubber trim goes so that will help too.

I think its depends what racing series youre competing in.
I know you can do hillclimbs in a production car with no cage at all on a national B license.
Ya see the odd MX5 in some of the higher classes with a roll-over hoop and 2 x backstay maybe with a diagonal brace for triangulation.
Maybe when youre entering a racing class that demands the cage is FIA approved that you need the full blown cage.
Mines there for rigidity with the plus benefits as if I do have an accident, I will have protection as well......which is nice to know lol

The front "edges" of the rim should be 1.9mm closer together than the rear. Or is it 1.9mm per side from a centreline down the length of car meaning that the total difference between the inner faces of the rim is 3.8mm between front and rear edges?

That looks simple........ Ugly as sin and that youre about to plough snow. But look at the Audi Quattro Pike Peak car from the 80s. It was gorgeous yet ugly at the same time, yeah ..........it makes sense in my head.
That thing is a piece of 3/4" ply for ya base, cut it to your shape, route a full 10mm rad on the front lip, by the time you layered up some filler on it, the ply will be 20mm. Then glue on slabs of polystyrene insulation from B&Q.
Shape it to the desired profile, skim of filler, (dont forget to PVA it or the filler will melt the foam) and boom you have a pattern. Soon make a mould and get a product from that.
You can unbolt it and use it as a standard westy while you tinker with Dive Planes for some fine tuning.
Maybe when I start moulding my front bumper youll get some more inspiration? Whats your strap line? Worry less, dream more!
Gaining an extra 40Kgs of downforce on the front end at high speed surely has to be a cheaper option that forking out for more traction on wider wheels and sticky rubber. Seems like you have nothing to lose.
Anyway, I set the alarm to come n play for the day, have a super day

Have a look at this page, its where I get some of my inspiration from
https://www.facebook.com/pg/Chrisisaacsracecars/photos/?tab=album&album_id=922312744451981
This is a good link also to get the basics. You need the underside slightly pointing down, only by 1 or 2 degrees. But reducing the amount of air flowing under reduces pressure and it will create an amount of suck down.
https://www.buildyourownracecar.com/race-car-aerodynamics-basics-and-design/
It will probably make little difference on a westy compared to a closed wheel saloon with a larger underfloor area, but adopt the principles as "good practise"as its better than having it pointing in the oppose direction and promoting lift .
No problem on the grp.............. if you need me to pop down on a Sat morning or whatever to get you started thats no aggro, just let me know either way. Happy to help.
Back to it, my shed looks like a bad day in Bosnia! Apologies to any Bosnians on this Forum.

Yeah ! Does this look like a panhard rod Westfield agony aunt problem corner...... Start ya own thread!
Ha ha ha ha I'm kidding right.
That's a far point jarno,...... I've never made a watts linkage as I've had enough clearance to cope with panhard rod........ But they don't look difficult.
A few mods before race season Jon? Need to get some more traction on that front end without chucking bags of cement in the passenger footwell.
Well, its not about clearence, its about movement. Panhard makes diff move too much, Wat doesent...
Unfortunately, my english isnt too good so I cant explain these technical things...

Post by: Jamie R on February 23, 2019, 01:28:13 PM
The centre of the diff moves laterally as well as it moves vertically due to the arc travel of the Panhard rod, where the watts linkage just allows vertical travel.
That work for you ?

Don’t panic your English is better than my Finnish, I know exactly what you mean.
The centre of the diff moves laterally as well as it moves vertically due to the arc travel of the Panhard rod, where the watts linkage just allows vertical travel.

Exactly! That causes whole diff live under braking and acceleration. And that means that rear rubbers contact to surfase is not optimal. When I saw Jons car, I saw that it was "Old school" stuff. There is room for improvement. However, at that point, it did work. But Jon and car has gone above that point. It just doesent work anymore... Sorry gents, just my few thoughts, Im drunk ;) :D

From from my Victorian wheel alignment tool, and yes, that IS a bracket for a hanging basket!!!
Got lots of shaping to go yet, and Im only one the first one. No seriously, Im doing to be doing this for EVER!.
The front wing will be interesting, as Im changing the position of the ridge at the top of the wing and lifting it up, hence the laser level... that worked out nicely.

Rear Toe will always need to have toe in as toe out is really dangerous on the rear, I remember reading about a jag that was sent out at Le Manns and was so unstable it resulted in a horrendous accident on the Mulsanne straight due to its instability due to setting toe out on the rear.
Jamie, what suspension set up are you running.
Maybe worth knowing that if your on stock Lotus arms at the front, that Lotus and many other F1 cars of the era of your car, used the main starting point settings taken from of all things-----------a Triumph Herald !
Maybe worth knowing that I always run the front parallel because when you plot out Akerman angle on any car, this makes the inside wheel as you enter a corner turn out a little more and this aids turn in "feel"
Hope this helps, even only a little. ;)

Here we go, this will give a good starting point.
Cheers guys,
Looking at this it looks like
Front
6 degrees of castor
1.4 degree of negative camber
Toe virtually straight ahead with a slight amount of toe in.
Rear
2 degree of negative camber
Toe virtually straight ahead with a slight amount of toe out.
I can see why toe out on the rear is "not preferred" as your outside wheel is going to be trying to whip you round, esp if it toes out further during suspension compression with weight transfer.
But the diagram suggests toe in on front, tow out on the rear.
........... and I was never going to use the Triumph Herald suspension lol.
I think by the time ive finished, only the rook panel with be the original lotus part un modified.

Flames and exhaust temperature will melt them.
And cause rotary is basically two stroke, they will be too restricting and may cause too much exhaust back pressure...

Post by: Jamie R on March 03, 2019, 06:14:00 PM
Did get as much done as I wanted :( :'( changed my mind on the shape of the front wing.
Loads of low spots still............. and theres no little flare on the edge of the opening..... so yeah far from finished.
Best to show what the wings were like before so y'all have a comparison how far out ive come.
Taking some styling cues from modern cars, they tend to have roughly 40mm gap all round the tyre. Unless they are slammed to the ground and tucked up in the arches.
Not a great fan of that look, looks like the suspension is bust, and this car lonly has 120mm ground clearance atm, even less when the underfoor aerodynamics get fitted.
Managed to get wet filler in my beard too!!! pfffftttttt .......bad weekend. :angry5: :angry5: :angry5:

Had a vist yesterday from a guy who makes motorsport fibreglass panels, so got a steer in the right direction on making the moulds, the new panels and grafting them on.
Reckon Im a month away from getting the new wings fitted yet, I hate cars!
I wanna be making brackets, underfloor bits,
Gonna have a try at painting it myself, gonna have a try at rebuilding the engine myself.....someone not too far away twisted my arm.

So Ive finally managed to shape all 4 wings.
Put the first coat of Crystic Primer on tonight. Mix it with the catalyst and brush it on like treacle.

If anyone would like to stick their 2 pence worth its more than welcome, as I have no experience here.
Ive acquired a freebie, double thickness ali rad, fan shroud doesnt fit perfect so brackets need cutting off and doing properly, couple more like 200 cooling fins are bent hmmmm.
How sensitive are the 8's with temp? esp with the mods I was planning...... :dontknow:
Is it worth pursueing or buy new??? :dontknow:
Ive gotta change all the front rad sub frame due to the shape of the wings, but thats no biggie..... rather get the subframe designed round a new rad if the stock one wont cope.
Dimensions of the diffuser isnt playing ball with the chassis design, :violent1: so Im off in to sulk with my bedtime reading

RE a V mount It's just a slightly different radiator intercooler set up.
Essentially three variations of a theme top mount is with the rad in the traditional position with a intercooler above the engine the big down side to this is heat soak plus point shorter pipe runs
Front mount the intercooler is in front of a traditionally placed radiator it necessitates longer pipe runs and obviously as you've a heater in front of the rad air temps passing through it are higher and tend to have less velocity offsetting this is cooler combustion air temps to the engine and less heat soak.
V mount has the cooler horizontally mounted (ish) with the radiator below and cantered back with ducting you can get full velocity ambient air temps to both rad and intercooler at the expense of more engineering and possible space issues.
Post by: Jamie R on March 28, 2019, 08:35:53 PM
Dual pass, 2 chambers, coolant does a double pass..so not in at bottom out at top easiest route...effectively in at bottom pass through to top, pass to bottom out at top..superior cooling.

Oh ok, I need to caviat it with, I'm not running intercooler as its N/A nor the air conditioner cooler/rad.
Just tilting it forward a fraction from stock to clear the bodywork.
No worries on the CAD, just bear in mind I'm far from an expert on CAD. I'm better at hands on, but I use CAD when it's quicker than building prototypes to prove something off
Post by: Jamie R on March 30, 2019, 01:56:33 PM
The new Koyo rad is on the horizon, and it needs tipping forward a tad more to get it under the nose cone! Most will call it a bumper, but Im calling it a nose cone, all will become clear (as mud)
So the original rad sub frame is junk, carved a load off but using it to hold the wood for the pattern.
So we're extending the front wings around the wheels a bit more and making the whole front flat rather than it pointing out in the middle.
Need to lay up some fibre glass on the leading edge of the bonnet opening and have a vertical return going down the flatfront.
The vertical flange will serve 2 purposes, firstly be the start to making the inner wheel arch "liners" with the integral louvres as per the RX8 to vent the hot oil cooler air into the wheel well.
The vertcial flange will also provide mounting for the nose cone, which will house the headlights, thinking of a similar set up as the 787B with polycarbonate covers.
The nose cone will have the splitter and dive planes, house the air filter too.
Its a long road.........

Id like people to put their two pence worth on a matter as I cant decide.
Im killing time after putting the first coat of gel coat on for the moulds and thought Id offer up some LED lights I bought a while back.
I sold the original lights well quite frankly the lenses were cracked, chrome pitted, and I didnt like the design of them, theyre off a Federal Jaguar I think, sold to the American market originaly.......... well I got £130 quid for 2 battered lights I hated. (First rear light pic)
Anyhow, universal LED combination lights tend to be a bit commercial for lorry trailers, tractors and kit cars etc.
So I cant decide on whether my original rectangluar ones modelled by chewbacca arms, round ones, or the lozenge shaped thingys.
The rear valance needs to be modified anyway to accept new lights, so its not a case of what will fit best, more of what looks more appropriate.
The round ones are deep housings, so they will be recessed into the panel.
Let me know what you think, but please dont say, put the originals back on! lol

The worst bit is defying gravity and laying up upside down, cutting pieces no bigger than 100mm x 100mm to prevent the weight of the wet matting fall away.

Interesting to see the choice of wheels on Jons car play an important part, with the whole weight or lack of weight issue.
Im going with 17" steels so hopefully the slighter taller sidewall and a bit more weight will cure any unsettling.
Love the sock in the shifter hole, better than that blue gear stick! lol
So for future reference....
Is there much noticeable diff in performance between Street and Bridge porting? Im aiming to keep the Rotus road legal so there could be a compromise on out and out power vs drivability....
Is it worthy of different gearbox internals, I don't need a full on quaife set, but should I be installing a close ratio set with long first gear or are the standard ratios fine?
I don't know how many different ratios are available for the diff. Im thinking it may be worth buying a few diffs off ebay and get them rebuilt with different ratios, then its a few bolts to swap them over and being able to have a play with different set ups?
Interesting from Jons thread a comment that says that the Adaptronic ECU "doesnt give more power"
Im still pondering that one, as I have far from a standard set up, and I don't have Jons electrical knowledge to over come any issues.
Is an RX8 steering rack available in quick rack maybe 2.2 or 2.4 turns lock to lock, then again I don't know what the standard is......
Electric water pump???
I have a whole host of others like separate oil tanks with 2 stroke oil??? but as you know im still fannying about with fibreglass and Im not even at the stage of chucking a freshly built engine back in.....
Just rather it was "right" first time.

Well, I have heard that there is big differense in engines behaviour between street and bridge port. In paper, there is not much, but engine pick up and so on is much better.
Good bridge port can make really nice power. I reckon you can go with full bridge. Aux ports and those valves basically determines how much that engine makes in top end. As for drivebilety, those aux ports opens in high revs, so I dont think it matters in street use...
If your car stays light, 6 speed box is good enough. As Jon said, gear rations at those things are great. 5speed box is basically same that FD has, so that wont brake. However, in paper, I dont know if those rations suits your car.
There is few options for diff rations. Unfortunately, I think it is 4.88, is that one that everyone want so they cost quite alot
As for ecu, Renny ecu is actually quite amazing. Really clever and adaptive. You can "flash" it with some mazda software
I would go electric water pump definetly. Remember, if engine is red hot, for some reason it stops, water flows thru it still..
Just few thoughts

With a properly Bridged Renesis the car will drive like a stock car till around 6800 then take off again like it has a small turbo fitted.
Is it worthy of different gearbox internals, I don't need a full on quaife set, but should I be installing a close ratio set with long first gear or are the standard ratios fine?
Maybe worth know that the 5 speed box will dump a lot of weight out of the car and without looking 1st is a longer gear. Next, although expensive fitting a 4.7 dif ratio (R3 Ratio) will not only help the car but close the gears up, effectively making a closer ratio box.
Interesting from Jons thread a comment that says that the Adaptronic ECU "doesnt give more power"
May not give more power but with the ability to tune the car would have better mid range power which in turn will push the car up the road faster.
Is an RX8 steering rack available in quick rack maybe 2.2 or 2.4 turns lock to lock, then again I don't know what the standard is......
Lock to Lock Turns (Steering):2.99 / I converted my rack to a non power rack to dump weight and get more feel (driver feed back)
Electric water pump???

Yes the CWP's are fully interchangeable.
For the rack, I posted my conversion with pictures around a year ago in my race car thread.
You need to chop the magnets off and make an adaptor to stop the screw being able to operate, pop the tin cover off and all will became apparent.

Not bad for a mornings work, complete front and rear end and calipers as spares.
Cousin needs the subframes back to make a jig, then he is gonna "bin them" in case anybody needs a subframe?
*coughJonRX8rearendwestfieldcough*
Im guessing the gear stick hole pokes through the car in the same place as the 6 speed, or am I making a bent knitting needle gear stick?
It dawned on me this morning, when I chat to Jon about mods to get the car ready he saves me money, when I chat to Clive, my wallet hurts. LOL!!

Good for you!
I was going off what you said the other night about welding an RX8 axle on the arse end.
I though it was a bad idea at the time, unless you can find a different disc caliper combo to fit over 15" alloys.
So..... youre looking for a yank tank back axle to cope with the RX7 power then? LOL
RE: lightened flywheel........ i was gonna stick with the stock one. Interestingly, talking with the cousin earlier he was saying he wanted a lightened flywheel for the track days becuase he found the revs were not dying down quickly enough when changing down because of the increased inertia...
Ill stick with stock for now, its something to possibly play with in the future if need be...... unless someone convinces me otherwise.

Just spotted this,
No no no. So many people get confused about light flywheels, 100% the inertia is decreased not increased.
First one I fitted to an RX-8 many years ago still leaves me with the impression that it was an improvement because it let the revs die faster allowing the next gear to be picked up quicker.
Even very early "engines" had BIG flywheels to make use of inertia to help stop things slowing down

The moulds don't bother me, it's cutting so much off the car, and not being able to brace the shell, and things moving about.
Hopefully the roll cage will keep things in check, as everything is tied back into the chassis.
I could try and weld some triangulation braces in here n there but I may have trouble arcing up lol

I think we're both arguing the same point here, but lost in translation or poor terminology.
It's one for a face to face discussion one day.
So..... The burning question
The 5 speed box.... Do I keep the 231 flywheel, is there any difference from the 192 version, and if I keep the larger 6 speed clutch, will the shaft on the 5 speed still engage, or do I need a different clutch plate?
I need to drive the car first before I can decide on lightened flywheels. It all comes back to whether I can maintain identity of an Elan for the purpose of a road vehicle, and not have to go down the IVA route.
The design features on a 70s car are unlikely to pass all the criteria within IVA/SVA.
I'm not going to waste time bringing a car up to a level to pacify some numpty who makes decisions in Brussels, I'm aware of my building capabilities, I know I can build a car that's safe to be on the road. I know we have to have standards to prevent cars being built from wattle n daub and chicken wire, but the IVA is sooo strict these days and is slowly preventing home builders building cars at home. Bloody Belgians .
So if I can't, it's all out track day weapon.

Real simple this one, keep the bigger 231 flywheel and clutch assembly and the 5 speed will bolt in as a direct swap. Prop and gearbox wiring is the same the only thing you will need is the gear leaver to go with the 5 speed gear box as the 6 speed leaver is different.
Hope this helps.

So, been on RBE web site and looking at Electric Water Pumps. Happy with the concept, and like the look of the additional LCD controller, will look ace sat behind the steering wheel as all the rest of the gauges are in the middle of the dash....
Anyway
1, The Davies Craig controller will control the stock fan set up? as well as the pump.
2, see photo, Im assuming behind my hand and the hose is the thermostat?
3, If i remove the entire stock water pump and use the blanking plate from RBE, will the thermostat housing and pipework inlets and outlets for the rad and heater disappear with the pump? i.e. its all one casting
4, if so, what is the best way to get the water back into the engine?
5, if I remove the stock water pump (weight saving :icon_thumleft:) is a ribbed belt available for the lower pulley and alternator?
Diff topic
6, I think i read somewhere, that you should use mineral oil as semi and fully synthetic fouls plugs. If I run a sperate tank just with 2 stroke oil in for lubricating inside the rotor housings, is it then beneficial to use semi or fully synthetic for lubricating the E shaft?
7, if my assumptions in Q6 correct can any one send any pics or links showing the set up?
8, is this the preffered method, by running a seperate oil tank, or did I just dream that up?
Thanks guys.......still feel like a fool lol

There are no stupid questions
Here is my few stupid answers:
1: I actually dont know can it control stock fan. I reckon that there will be some difficulties cause stock ecu is quite clever, you have to overwrite it somehow
2: Thermostat should be under upper neck of waterpump
3: There is neck adapters for removing stock water pump. However, you have to figure out how to do modify whole cooling/heating system. And you need new thermostat to control it
4:From that adapter, water goes back to engine. If I remember correctly, from left water goes out, from right water comes in
5:Dunno for sure, but removing that pulley, doesent matter. For alternator and you can use just one belt, straight from lower pulley
6:I dont know, there is so much different opinions
7:Im not sure how Rennys OMP works, but I reckon it doesen matter.
8: You can just block of normal oil feed to OMP and get that oil from seperate oil tank
Hopefully this help abit ;D

When MRC was formed there was only really the RX7 Club forum in America to turn to and at the time if you asked a question they presumed you should know they would call you stupid! Not Good!
Anyway, Water pump, I have run this electric pump on the race car, plus we sell quite a few of these with no reported issues.
The plate for the RX-8 water pump just removes the pump leaving the water hose connections in place.

I do actually understand what its taking to make all this happen as the car in the picture was designed and built from scratch by myself and a friend of mine in the early 1980's.
The whole car bar the roof was fiberglass, we even made the car longer and never got caught, the extra length was because I had the rear axle 3" back further than stock to make the car more stable. Proud to say I won a lot of races in that car

He tried to restore a couple of mg’s back in the 80s but for various reasons he never had the time or the money to finish them.
He loves it, as he never had the opportunity.
It can be frustrating at times because I know in my head how I want to build it and the process involved, but he just asks a million questions which I don’t mind, but he asks the same the next day bless him.
Wouldn’t change him for the world tho, it’s like help the community. Lol. All joking aside, it comes in handy having a spare pair of hands and he gets to see his daughter more frequently which is good since the big C. And he makes a brill coffee.
He is looking forward to jdm.

376 clive??
You been around the block a few times lol
You could say that, I started racing cars when I was 16!
376 this was from a formula called National Hot Rods (NHRPA)
The numbering system went national so no two drivers turned up at the same event with the same number.
The first number dictated the promoter you raced for,
Great thing about that racing was, no entry fees, traveling expenses plus proper prize money to go with the trophy's.
A lot of circuit drivers came from this formula / Martin Brundell, Derek Warwick, Rob Collard, Matt Simpson, Colin White to name a few.

Offered up the wing on Saturday.........didnt go well....... didnt like the fancy brackets I bought, but they were for steel panels.
Made some crap brackets at work and literally screwed the new wing on, to the body......feathered the joins down ready to bond it with GRP.
A couple of dodgy cuts, but nothing that cant be cured, just as well Im not trying to weld it on.
Either way up, it fits, its on, more fibreglassing !!!! grrrrrrrrrrr

Keep fannying about with the gel coat on the first one, rather than cracking on and worrying about the aesthethics when its time for shell prep.
Anyhow, progress is progress.
I used to be in disbelief when some of these custom car builders say they can easily put a 1000 hours of prep in before laying colour down.
I can believe it now, and ive not gone anywhere near filler primer...... jeeez louise
Post by: Jamie R on May 31, 2019, 06:16:52 PM
Fronts have commenced....... cutting the front off was more tricky with the cockpit walls to contend with.
I can get a decent shot of the complexity of the headers now...... still more welding to do on them when the engine comes out.
And knowing what I do now since joining this forum, i'll definately be coating the headers in Zircotec Ceramic stuff.
I even had Bailey helping me today which is completely unheard of .....so Im posting a pic as living proof coz if I told anyone we knew they wouldnt believe me.!
Post by: Jamie R on June 04, 2019, 07:46:43 PM
Starting to graft the first wing on with GRP, always looks messy at this stage, but the crappy brackets work well in lining the panel up to the car.
Then I decided to cut out the boot floor comprising of the original spare wheel well and exhaust tunnel, all of which is no good for my application.
This is making way for the new exhaust routing but more importantly, gaining the right angle for the diffuser at the right length to exit the car.
The raduised exit of the diffuser will blend into a rear bumper as well making the whole part look cohesive.
Flat aluminium floor from the front splitter to the rear diffuser looks a simple task.

Well positive and productive weekend.
Fitting of the last wing today, got a 2mm twist out the mould, the inner wings will cure that.
Trial fitting of the boot lid since the new rears went on...... got a 5mm gap tapering down to 3mm on the sides.
I put that down to 70's build quality build tolerances, being fibreglass and it being a Lotus lol. Its the same on both sides.
Build up with some gel coat n sand back.
Modded the "throne" for the better half.
Was looking back at the build process yesterday, started the wings with the wooden wheels on 21st Feb, so thats a month a corner!

Looks like bespoke padding as well.

End of an era....... sorry its been a boring topic and its not working with the rotors, but today is a huge achievement for me and FIL as weve never done this before.
Ive trowelled the gel coat on the last wing, in readiness for tarting it all up and getting it as smooth as i can before it gets filler primer.
Lots of divets to go round the car and fill in but rather use gel coat than body filler at this stage.
Structurally all the wings are sorted, just cosmetic stuff.
Whats next I hear you ask...........
Well I thought I had finished fibreglassing and was moving on to mechanical stuff, but the rear lights turned up today, so Ill be making the buckets for those so they can be frenched into the bodywork.
Ah well, metal work soon !

Made a plywood former, shaped, primed, sanded, waxed.
I hammered 2 x cut down panel pins with the spike pointing up.
When I lay the glass over the top it will produce 2 x drill starts in the product, saves marking it out for the mounting holes, and its repeatable for the other side.
More cutting of the shell to graft in the new buckets.
Another productive evening, we like that.

Not got all the rads blended in on the edges of the buckets, but theyre on.
Im back to fitting the exhaust again............ I need to rethink that too.
Ive learned a lot since joining this forum, and I need to re-route the pipe work near the diff. Ive never been 100% happy.
So I have a question. I have a resonator fitted as youll see on the last pic, but its going to hit the floor and annoy me so that needs relocating too.
Does anyone know if there is an optimum place for a resonator to be positioned in relation to the silencer and the headers? Can it go just before the silencer?
Thanks in advance
Post by: re japi on June 21, 2019, 04:56:41 AM
But one thing comes to mind, heat control. Rotarys generates lots of heat. You have to figure out how to get that heat out of engine bay. Also, under floor, seems a tight fit. Hopefully it wont melt that classfibre...
Post by: Jamie R on June 21, 2019, 06:56:21 AM
Zircotec the headers and decat pipe.
Everything else is exhaust wrap and self adhesive ceramic sheet.
Some NACA ducts on the underfloor feeding air into the exhaust tunnel
I don't have many options, this car is tiny. There is zero room.
The only other thing I can do is run the pipe straight out the bonnet and put some flaps on the ends like the vertical stacks on the American trucks lol

Not sure if you have done much research on Zircotec but the coating is not to be confused with any other form of coatings which people often do.
I had my manifold, Turbo and down pipe coated. I am going to get the current Turbo coated like the old one was because even after a race you could almost lay your bare hand onto the housing!
Also have a look at Zircotec Zircoflex Form Rigid Formable Heat Shield as this kept my feet nice and cool in my footwell last weekend.
I actually blistered my foot at Brands through my race boot and wish I would have used it sooner.

I've only experience with turbo motors, 3 inch systems and quite a bit of overlap so strong exhaust pulses Jamie but on those the resonator seems to work best around 24inch from the downpipe. My default system now tends to be a flexi section right behind the downpipe into the resonator the pics of a larger 1 into 2 resonator system but you'll get the idea.What size down pipe? I have to figure out that resonator thing too. What DB your car has?
Btw, that turbo looks big

Looking at the pictures, I would Zircotec as much as you can afford at least the system from the engine block to under the car, especially where it goes through the body. BTW beautiful pipe work :great:

Yeah, that's the plan. Mainly on the headers because they come upwards on my application, right next to the chassis so that will have the powdercoat melted off it, and the solenoids on the intake manifold, and the OMP stuff is really close, and the steering column, and, and ,and.
The decat pipe was either ceramic coating, or that yellow rigid stuff you shown, formed in a U channel and bolted to the bulkhead with the open end facing upwards and it will protect the belhousing and intake from the exhaust. Then some vents in the bonnet.
There are lots of options really. I could even combine heat protection i.e. exhaust wrap + heat shield. I know on the RE Amemiya 20b Lotus Europa he lined the bay with gold coated panels as that's a good reflector of heat.
Im a long way from all that to be fair, once the shell is painted I will be going belt n braces on the heat side. Im always thinking 3 or 4 steps ahead on all the stuff I do, (easy when youre an over thinker like me lol, screws up my personality tho) .... if I make this what else does it affect? yadda yadda...... where I fall down is my lack of knowledge on rotarys.... that's where you all come in :icon_thumleft:
Thanks for the nod on the pipes, thankfully I don't need to redo the engine bay, just the stuff under the floor and near the diff. I really need to find out about the resonator and relocate that. Im buying some more pipe and bends today. I need to hack some more GRP floor away, but its under the fuel tank.... lol don't panic.
Oh and because of the diffuser, the tailpipe will be side exit, driver side so I can see any flames in the mirror lol.

Severely modified, had to cut 6 " out the overall height because the exhaust tunnel has jacked it up.
And cut 3 of the 4 "wings" off to miss the centre console and so you can get in.

The main reason for the sticker is to prevent the paint lifting when I send it through the car wash.

CCA for this battery is 630A
Not a bad size for a Lead Acid battery, but obviously not light ;)
If you are into serious money and weight saving, then Clive can undoubtedly advise on a suitable super lightweight racing battery, similar to the on he uses in his race car. which you can pick up with a little finger, as they are so light :)
Post by: Jamie R on July 03, 2019, 05:19:58 PM
Its good to get an idea on a good typical spec in terms of CCA.
Im now going down a path of the Lithium Ion ones.
Ive seen that Clive runs a Ballistic EVO3......... been on their website and they say they are no longer trading as they cannot compete with chinese manufactured competitors.
A few on eBay America, but postage is daft from the US.
A shop very close to me sells the below, and the supplier is in the same town as the shop.
Yup expensive, but lighness is key with the car. Im not going to have the most powerful engine in the world, so taking on board Colin Chapmans philosophy of added lightness.

Glassing the holes back up on the passenger floor to give clearance for the exhaust.
Wooden wheels have been back on to make the inner wheel arch liners.
Made them extra large so I can trim them back to suit the profile of the cars front bumper/nose cone.
Inner arches will have the oil coolers mounted to them with vents into the wheel wells.
Tacked together a new sub frame to mount the new Koyo so it misses all the proposed bodywork.
More glassing ahead to make ducting feeding air in and away from the rad.
At least I smell of welding today and not resin.

:sign0098: well done clever clogs, they're the outlet ducts / mounts for the oil coolers.
I know the size I need big end and the small end is 20% of the surface area of the big end to help the air speed up.
I know the length, and the convergence angle........
Easiest way I could think to make them was to make the volumetric shape of the inside where the air travels.
Sand all the rads in, smear it in filler, sand, prime, sand, wax, gel coat, GRP and voila, push the polystyrene out and I have a left and right hand finished product, no moulds required, the inside surface is nice n smooth.
Post by: Jamie R on July 12, 2019, 06:30:19 PM
The silence is killing me, I need to post summat even if its trivial.
Started the flat aluminium floor today, first piece in.
There will be a total of 6 aluminum sections for ease of fitment/removal and then the GRP splitter and diffuser.
The bent edges allow an easy join to the side sections, but "hopefully" the bottom edge of the vertical sections will create a vortex.
This should help prevent air rushing underneath from the sides and disrupting a 700mm wide channel of high velocity low pressure air which runs the entire length of the car.
Fingers crossed, but it can all go horribly wrong. Ive never designed and built aero like this. Ive done research on this its kinda thing past few months i need to stop being indecisive and flitting between different theories.
Build it, try it, test it.
If at first you dont succeed, suck some more seed !
Post by: clive on July 12, 2019, 08:50:11 PM
Just an observation as im no aero expert, but with the flat floor you have built, I think for stability you will a rear diffuser.
Also don't cover your gear box an diff from air flow as I know somebody who did this with his FD and had sensors fitted and found he was frying both units.
Hope this helps.

Evening Clive,
Yes diffuser already designed and is in the list of things to build.
Point taken on the gearbox and diff, NACA ducts are easy to fabricate, so can strategically position some of them.
Does the rx8 box and diff have sensors fitted? ? ?

Wind down the tunnel...turned the back off the car into a parachute blew it off, broke the rivets off. The air going down the tunnel needs an exit path at rear of car. Mind didnt have it.
On the gearbox there is a neutral switch and a reverse switch. The loom is on the end of the engine loom. This also has the rear 02 sensor on it.
Rear 02 and reverse switch if you dont want reverse lights can be done away. Neutral switch can be done away with but may be cause idle to hunt. Easy way is to map an 1100 rpm idle which sorts the hunt and also brings up idle oil pressure which at 850 rpm is naff all...i had about 10 psi of oil pressure @ 100deg C oil temp idling in pits, 1100 rpm good 20psi plus.

Post by: Jamie R on July 13, 2019, 06:16:28 AM
Just going back to the diffuser topic.. I'm certainly far from an expert but doing a lot of research lately , the stability from the diffuser is offered by the downforce it produces
When a flat floor transitions into the diffuser, it's as that point where the most downforce is produced. Race car builders will want to start the transition as close to the middle of the car as possible. So a percentage of the downforce will have an effect to the front suspension as well as the rear.
But rear suspension positioning and the droop of the suspension on the inside of the car when turning on a bend will clout the diffuser, so clever car design benefits.
Formula 1 is a great example of popular misconception that if teams build aero such a way, it must be right. Wrong. Teams are faced with different rules and regulations season after season, and what they build is the best they can achieve without breaking the rules, doesn't mean necessarily it's the most optimum design. Us mere home brew car builders only have 2 restrictions, lack of resource and lack of knowledge and experience lol
The transition from the flat floor to the diffuser needs to be smooth with an optimum angle of 7 degrees. The main purpose is to allow high velocity low pressure air to gradually go back to low velocity high pressure air when it meets the air flowing over the top of the car.
If the angle of the diffuser is too steep or the transition is too abrupt you will get air separation which creates turbulence and a partial vacuum. The best way to envisage air separation it go to your kitchen sink, turn on the tap and hold a spoon under the flow of water. The bottom underside rounded end of the spoon needs to be in the flow of the water.
The flow of the water from the tap is the air travelling underneath the car, the rounded bottom of the spoon is the diffuser. Let the tap run and you'll get a constant stream of water in a straight line, then when holding the handle vertically down almost parallel with the water offer up the rounded bottom of the spoon into the stream of water.
The water clings to the contour of the spoon, changing direction of the water as it creates a boundary layer with the spoon. The air under the car does exactly the same. You can change angle in which the rounded bottom is presented in the flow of water and if it gets too steep, the water can't cling to the surface of the spoon and the water goes all crappy and broken up, that's exactly the same as air separation which is bad on cars.
Ideally the air on the underside needs to flow into the air from the top of the car and meet nicely at the rear without creating a vacuum.
Transit van on the m5 doing 100 mph, the air flow from underneath, over the top, down the sides of the van will very rarely get anywhere near the rear van doors, you'll get a vortex behind the van and some air will spill into that void. But by n large that void is a vacuum which actually slows the vehicle and tries to pull the vehicle backwards so the air from the flow can fill that void. Not good.
Lastly, ( as I need to get up n go in the shed, insomnia ruined my night ) another misconception about diffusers........ The vertical strakes that you often see dangling from the diffuser is not to channel air and keep it in a straight line.
Imagine a diffuser with no strakes at all, one big channel of air from under the car flowing nicely out the back. Soon to be disrupted by the turbulent air that's coming around the rear wheels as it spills into the area of the diffuser. It's called tyre squiffing or something like that I can't remember the name, anyway, the turbulent air, enters the diffuser and disrupts your nice air flow and negates all your hard efforts in producing downforce.
Add in some verical strakes, say 2, so the diffuser now effectively has 3 chambers LH, centre and RH. At the bottom edge of each strake, you will get a vortex, it always occurs to the side of the strake but adjacent to the bottom edge. This vortex helps to prevent the turbulent air from the rear tyres entering the next chamber along, so the LH and RH chamber will have a partial disruption from the tyres, leaving clean flowing air in the centre chamber from the underside of the car to create the downforce at the transition from the flat floor to the diffuser.
Add more strakes ( with a trade off of more weight) and you'll have more chambers in the centre of the diffuser that are uninterrupted by turbulent air.
Put a 90 degree bend at the bottom of the strake like an L with the bend pointing from the centre outwards and you can move the vortex closer to the ground without reducing ground clearance which is even more beneficial.
Right I got pins n needles in my left arm from holding my iPad in bed. Getting up.
I'm not an expert on this, and sorry for "ladybird booking" what I've learnt so far.
Just hope all these theories I've learnt work, I really don't want to upset the classic lines of the Rotus by putting a spoiler over the boot.

Coffee...
The air that enter under bonnet area via rad etc...then travels down transmission tunnel cooling gearbox and exits where? You need a vent at end of tunnel.
Rx8s and Rx7 get hot gearboxes and there open to the air under the car.
I think you need a vent in the back of the car above the flat floor.

Post by: Jamie R on July 13, 2019, 03:29:32 PM
There will be some extra ducts in the bonnet to help push any exhaust heat out.
There will also be a duct feeding cool air into the exhaust tunnel and will be vented at the back.
I plan on putting some ducting on the flat floor to cool the gearbox and through the tunnel to the diff.
Should be able to mount a vent at the back of the chassis and direct away from the car.
Cheers Big ears :icon_thumleft:

If I redesigned the diffuser to an 80's / 90's formula 1 style diffuser like in the below diagram..........
Where it says "Gearbox" I could route my exhaust out that point and any air that goes down the tunnel that cools the gearbox and the diff can be vented out the back as it passes the silencer.

A T2 diabetes diagnosis is obviously very bad news. My BIL was diagnosed with T2 about a year ago, but went on the NHS programme he was offered and dramatically changed his diet as a result (very low in carbs) and walked several miles most days. He lost ~3 stone (from 13 to 10) and his doctor says he no longer has diabetes. He reckons he will have to stay with his lifestyle changes to keep T2 at bay, else it will return. But, he says he feels so much better and it's motivated him to stick to his current regime, which he's adjusted to and finds quite easy now. He had to buy a whole new set of clothes too, as nothing fitted him any more, having lost ~4" around his waist!
Best wishes to you both at what must be a very stressful time.

Emma’s had a lumbar puncture done.
Ah the t2 don’t bother me, the ironic thing is I started dieting a few weeks back and I’ve gone from 18stone 4 pounds and today I was 16 stone 10 pounds.
I’m aiming for 13.5 ( and I’ll still be heavier than Jon grrr lol ) I’ve changed my eating habits dramatically as I’ve done nothing about exercise.
I was gonna treat myself to a new mountain bike but I went for a job interview the other day and the commute would be stupid, so I’ll see what happens with work, if I stay put I’ll buy one then .

I’m in the shed, Emma phones at 6pm to say she’s been diagnosed with multiple sclerosis!
I’m a mess, her dad who was with me is a mess and we hot foot it up there.
We’re all going through scenarios and about 8 pm the neurologist turns up.
He is convinced she has transverse myelitis, she has an inflammation in a third of her spine caused by perhaps a virus and her immune system is attacking her nervous system.
She could get it again and it could lead to multiple sclerosis.... but one day at a time.
Next 3 days is iv drip of steroids and because the inflammation is so large 60 mg of steroid tablets and tapering off over the next 3 months,
We’re good for holiday in Wales and Baileys graduation next week and we’re good for Portugal later in the year.

Well, that's not good news, but some relief in that it's not as bad as the initial diagnosis. I'm so glad you can continue with your plans for the near future. As you say, one day at a time for now.
Nope we’ve had better weeks but she can feel her feet more today so the steroids are helping with the inflammation of the spinal cord.
Could last weeks, or months, or a year before she fully recovers. Strange as it sounds I’m looking forward to being nurse next week. If she’s lucky I’ll give her a bed bath .

Thanks for the kind words and wishes.
Its not all doom and gloom, Me and Emma have been through the wars the past 3 years, we lost our daughter at 17 weeks pregnant, 3 failed attempts at IVF and now this.
But we have each other and that wont change, I have my mental health issues and she has her physical ones, we help each other and thats whats important.
If the worst happens we adapt....... doesnt mean we should stop. I have a good friend who is paralyzed from the 3 vertabre down after a bad motorbike accident, that was 13 years ago, he still lays slabs, he still wheels himself to the garage, drags himself out the chair into the engine bay and works on his cars.
Dont let anything stop you!
Anyway, on a lighter note, were still making progress, the outlet ducts for the oil coolers are done and will be hopefully mounted today before i go see Emma.
Im not too concerned on the heat from these, as standard these oil coolers are fitted with rubber shrouds, and they dont melt. So im mildly happy.
Thanks guys, and despite everything, keep smiling.

Like others, it's hard to know what to say, other than to pass my best wishes to you both and hope Emma gets better sooner, rather than later.
Nice progress on the Rotus too :great:

I strolled into the discharge lounge yesterday to collect her, I said, hello my little nest of vipers. Much to the disbelief of the other patients.
Grabbed her bags, and she's tottering behind at the speed of smell. I turned around and said, will you hurry up, I was clean shaven when I arrived!
Anyway, Rotus work will be non existent this week, we're gonna be lounging about in the hot tub. Dunno what the wifi is like, or the 4G , so probably see y'all at the rendezvous point on Sunday. Fingers crossed for good weather. :icon_thumleft:

Same diameter as the roll cage but lighweight seamed tube.
Strong enough to hang the exhaust and diffuser off, but light enough to buckle in the event of a rear ender without destroying the roll cage.
I save the cage for a "big off"
The MSA blue book mentions not letting the roll cage extend past the suspension anchorage points.
Not sure of the reason but.....yeah.
Post by: Jamie R on August 02, 2019, 07:39:52 PM
Mocking it up in steel first, cover it in filler, make a mould, and then product in GRP (nothing new there)
Gotta put a few more pie cut pieces on the tail pipe to joggle it up into the boot area to route the silencer in the "vent" section.
Carved up and remodelled the horrendous original rear bumper to meet the bodywork better and form the mounting part of the diffuser.
"Fired up" my new shrinker / stretcher for the first time since my birthday in June....... im impressed.
Its shrinking 1.5mm nicely and was only supposed to have a limit of 1.2mm on steel.
Post by: Jamie R on August 03, 2019, 05:29:54 PM
Been messing about with the last bit of the exhaust.
Lost 10" out of the silencer as it was purchased to sit transversely in the boot with side exit. Now exiting out the vent. Its certainly lighter.
Made a exhaust "saddle" similar to what they use on go karts...... couple of springs over the top. I'll stop the bugger from moving !!!
Cant fit it properly yet, stupid diffuser in the way! Who designed it like that? ? ? ?

Shape wise it's come out a lot better than I originally thought.
CAD only tells you so much, but it's a nice guide. We made some real life alterations from the model, and the roof of the diffuser follows the underside of the rear quarter nicely like as if we planned it lol.
We can see what else we can add around the rear wheels to channel the turbulent air away from the diffuser that's come from down the sides of the car and out of the wheel wells.
It's getting heavy now all that steel. Can't wait to lift it off and get it on a table.
Post by: Jamie R on August 08, 2019, 09:29:46 AM
Everything I touched turned to dog turd! grrrrr.
Gonna make a jig today and chuck the diffuser at it. Its not working building it on the car, bits move from welding, crap floating in mid air and hoping for the best.

Post by: Jamie R on August 10, 2019, 02:36:24 PM
I knew this day would come........ the Rotus is up for sale!
Joking!!!!
Nope, I made a right hash of the diffuser pattern. Too much weight, panels under tension, stuff moving, nothing straight.
Well when I say its a hash, its not as accurate as Id like, so its in the scrap pile for the gypos...... the steel, welding gas, wire was all free.
Just dont like wasting time.......... so its back to spending money and glueing polystyrene slabs together and carving out the shape.
I guess Ive got the dimensions from the previous one to replicate.
Oh well................... could be worse.

I once made a mould off the type of thing you are showing for a bonnet and back end of a V8 Sprint car.
Another little money maker along the way, NOT !
p.s like the paper weight.
Post by: Jamie R on August 11, 2019, 12:42:57 PM
That was the intention with the metal one, it was a pattern to take a mould off, but it wasn’t to my standard, things moving from cooling contraction on the tacks. I wasn’t happy with it so it would bug me if it wasn’t right.
I’ll just carve it out of polystyrene and lay up some grp for a mould. It’s not a major setback.
Yeah an old motorbike engine always comes in handy.

Post by: Jamie R on August 13, 2019, 01:19:03 PM
You take all the mechanicals off an RX8 and you graft them onto a car that will be half the weight, lets say from 1400Kgs down to 700 -750 Kgs
Ignoring the lack of ABS, fitting of bias pedal box, master cylinder bore sizes...... Also ignoring the unsprung weight factor
Do you think the stock discs and calipers from the RX8 will be man enough to haul up the Rotus?? Or invest in upgrade regardless? Maybe its a suck it n see......

Post by: Jamie R on August 13, 2019, 02:54:19 PM
That's good to hear. In addition to this I purchased some 17" inch steels to keep the car look more "period" (better not make the diffuser out of carbon fibre then lol )
The 17" steels fit over the stock set up quite nicely with ample clearance. Maybe because the wall of the steels are thinner than the alloy wheels
I was concerned bigger calipers would hinder that.
I remember my old Mk1 escort with 2.8i Capri bilsteins converted to coil overs fitted with Austin Princess 4 pot calipers of all things.
I had to relieve the calipers with an angle grinder to get the 5.5J mexico steels to fit....... not an ideal situation

Anyway, slightly diff topic......... cant find the paint code for mandarin orange, so for the ease of touching up as im bound to have a bang or scrape while im learning to drive again (track style not road style) ive decided on a standardised colour that anyone can obtain.

231 and 192s do not dyno at there published figures but do go up the road and bum dyno suggests its accurate and head to heads with similiar powered cars.
Some reasons are the stability control system senses the front wheels are not turning and rains in the power...
So bridgeported de catted modded cars make 200 whp standard cars are making 170whp on rolling roads.
The traction control system can be turned off but its never really off still has some control.
People say that if you press and hold button it completely switches off but im not so sure as generates a fault in system. That resets on cycling off power.
Westy runs a street port...with 231...at 4.1 final drive...at 560kg...its rapid acceleration in 1 2 3 4 then ok in 5 and dull in 6th.
I think your gonna be fine with the standard 4.4. But if not swap out later on...
The converted mx5 i drove was a 5.? Still wasnt as quick as Westy...but on ohlins handled sweet. But power to weight is your friend.

Cars with disabled traction still yield low numbers on dynos.
And Clives car being an oddball with twice the standard power he has had all sorts of issues with the rear brakes and afrs going funky when these systems were active...
All the electronic aids are gone now and a pip map no more engine blow ups...
I dont know is the answer but bum dyno on an 8 is better than a real dyno.

All the dsc/abs unit does its send a signal to the ecu to limit torque and power. If this dsc system is missing or switched off (hence the dtc) the ecu remains producing full power.
A fail safe on the bmw ecu if the abs signal is missing, is to put the ecu into limp mode (5k max revs) I remove this when I map ecu's.

Cheers Jon,
Im in a bit of a quandry.............. Its all about budget and ease of swapping bits.......
... yeah I probably will be fine with 4.44 diff and run my 5 speed for a bit of added lightness, but the car is built for the 6 speed, so I can pop that back on without any dramas of cutting chassis rails off etc.
I'd love to buy a brand new 4.77 cwp off Clive, but then I need to budget a diff rebuild.
Ive just located an R3 diff complete for 375 quid collected with 56k miles on it, at that price I'd take a punt.
Then I have a "plug n play" with diff swaps for different locations etc. for the sake of a few bolts

I've done a fair bit of playing with bmw ms43/2 ecu's and the abs/dsc unit is practically identical to the mazda rx8 unit.
All the dsc/abs unit does its send a signal to the ecu to limit torque and power. If this dsc system is missing or switched off (hence the dtc) the ecu remains producing full power.

Mr Flopsy was quite often covered in his own poo, straw, matted furr, engine oil, under seal . He was grim, wouldn't change him for the world, and will never replace him.
If we had a drink down the bottom of the garden where that pic was taken, as you got up, he use to run rings around your feet so you couldn't leave.

I wanted to try and maintain the original lotus lines as much as possible......
.... Ive been told by 2 different people that the +2 was called the "slippery" elan due to its drag coeofficent of 0.3 which was excellent for its day compared to other cars of the era.
Ive not found any evidence on t'interweb to back up this nickname but the figures are true.
To put it in perspective, fast forward to 2018, the Mazda 3 has a coefficent of 0.27 and it is the top 10 list of the most aerodynamic cars of 2018.
It would be a shame to change the classic lines, but as Ive changed the wings and the front end, added diffuser, its looks like im going to succumb to the fitment of a spoiler.
The slippery nautre is great for fuel economy ( well the rotary has thrown out that arguement ) and for a greater top speed (lose my license on the road or find a track with a long straight to find its top speed)
The trade off will be added drag on the back end for increase downforce with a fitment of a spoiler and other flaps.
Clive gave me an insight at Beaulieu about Dan Gurney who fitted aluminum plates on the back of NASCARs etc but made them interchangeable.
So I thought a spoiler with a feature so I can play around with different size flaps... we're only talking flaps an inch high if that but they make the difference.
So this morning I started laying out the base on the original boot lid, just to get the right shape and it uses up the last dregs of resin......
The diffuser mould comes off today, wont be doing anymore on that till after my holiday.
p.s. I posted the blue Lotus coz I know Jon likes blue!

I've made the exits ducts from the back of the oil coolers which Jon called "Emma's new shoes" and the air is funnelled into the front wheel wells.
I'm having a thought of utilising that spent air and use the same air to cool the discs..........
Therefore.....
1, do you think the discs need cooling on a light car?
2, I don't know how much the air passing through the coolers will increase in temperature by passing the oil coolers, there’s only the plastic wheel liners behind the coolers on the standard rx8 set up. I certainly would have thought it will still be cooler than the discs.
3, Clive where did you buy those backing plates with the ducts built in from for christine?
I'm just thinking of being "efficient" during the build....
Post by: Jamie R on September 08, 2019, 12:21:24 PM
Just wondered if it was worthwhile exercise using that air to cool

The overall height is bigger than the space I got and the overall width means if I butt them up against the oil cooler they are wider than the wings lol
Ya have to take a stab at these things now n then, they only set me back 50 quid for the pair, I can relist them on ebay, no great shakes.

......thought about making a tool to make my own wheel centre caps out of plastic.
The obvious choice is rotor shaped, as the car is neither Lotus or Mazda anymore.
Lay them up in GRP in a mould with black gel coat and then machine the boss on the lathe.
Couldn't think how to make the rotor shape in aluminium as I don't have a milling machine......and plastic is lighter. Colin would be so proud.

..... need to shorten the silencer by another 1" :angryfire: :angryfire: but hey ho its no biggie.
happy with the overal fit.. looks like there will be enough suspension travel for the lower arms.
Any resduial air that comes down the transmission tunnel that doesnt escape out the centre vent will pass between the top of the diffsuer and the boot floor and scoop upwards around the bumper.
Couple of tweeks required, the bolts hanging out the bottom of the diff need shortening, easy fix.
Oh and the father in law just landed an unfinished lotus 7 replica 80% complete for £600 ! :violent1: Jammy *^%$£%$^&**

Staggeringly amazing work :13:Cheers Clive.... It looks the part..... The amazing part of it wont be revealed until it's finished and I can find out if it actually works. I've done enough swotting and research on the topic, but I think I've only scratched the surface still lots to learn, and you can only make your best guess using formulas and case studies as I have. There are no hard and fast rules, cars are vastly different you can fit the same part to 2 different cars and get varying results.
BTW I think when its done the car should be presented for the next Bond movie, after all you do have the rocket launcher in place ;)
The real successes are being out on the track like you do, and seeing if it physically makes a difference, but I'm not there yet.
I won't be making a wind tunnel in the shed lol.
I'm under no illusion, I won't be designing multi stage wings for the front of Lewis hamiltons formula 1 car; but air is one of the few things in life that IS free. I may as well try to use it to my advantage.
Getting to grips with this dark art of fibreglassing. I dare say the father in law will get me roped in to making him stuff for his new toy.

Weve been to see a private neurologist today to get some answers.
Contrary to what both Emma and I believed, Transverse Myelitis is not a condition in itself but an outcome of an underlying problem; in the same way that people get headaches caused by stress or eye strain etc. (So weve learned something) *First tick*
We saw the MRI scans today for the first time and we have been told that there is a 99.9% chance its not Multiple Sclerosis, or certainly the evidence suggests that. *Big tick*
They are confident this condition is a one off and Emma will make a full recovery but they cannot say how long it will take, it could be 3 months, it could be 3 years. fingers crossed.
More bloods required to rule out anti bodies in her system that could be related to Neuromyelitis Optica or NMO. If her body is clear of this anti body then she can come off the steroids immediately as all they are doing is controlling the inflammation on her spinal cord in case she does have NMO. Another big tick as the weight gain is getting her down. (Gravity works like that lol)
So, possible causes that attacked her nervous system in the first place. NMO, being run down, eczema, thrush, flu, or a B12 vitamin deficiency which apparently is also an auto immune condition.
We may never know the cause, but the good news is that there is hope of a full recovery, just need to be patient, and in the grand scheme of things, if you rate her level from 1 being having the condition with no symptoms to 10 being completely paralyzed shes around a 2 or 3......
Certainly a dark cloud is gone from my mind

They are not expected to do much on their own.
They assist the main diffuser to be more efficient by stopping turbulent nasties off the rear wheels entering the main part.
Plus venting air from down the transmission tunnel.
