Title: Rotus Project Build
Post by: clive on November 25, 2018, 10:38:54 AM
I have had an e-mail in for some advise on this fascinating project.

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: .

Evening all,

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 ......

Welcome mate, very interesting project. Be nice if you do abuild thread, we get to see it what your doing and you get a permanent history to refer back to...i find it great on mine  info ive forgotten piccys etc to jog the memory few years down the line when addressing any issues.
This car gonna see any track days?

Hi there,

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 😆
Title: Re: Rotus Project Build
Post by: boosted on December 02, 2018, 06:58:51 PM
Stock rx8 pressure is 4 bar, Clive wouldve meant 8mm id. Nothing fancy required upto you i just use 8mm id fuel hose with fuel clips ( not jubiless) they fix to the rx8 push fit fuel hose connector at fuel pot and fuel rail.
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.

Track work...cool...comes with a few headaches ive found the hardway with the Westy on slicks...
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.

Hey Re Japi

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.

The rest they say is history

I can see that your a fabricator ! Air intake good idea to fit 1 of the rx8 air straightners.in your intake. (Sieve mesh circular thingy)..sorts out the airflow so the maf can get a proper reading...without throws lean codes.

Hey boosted,

Not booster like the other night, damn fat fingers!

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:

Right, im off to look at the plumbing on the fuel lines on the RX8 manuals, somebody not to far from here told be theres no fuel return line to the tank, so thats blown my design apart lol
Title: Re: Rotus Project Build
Post by: boosted on December 03, 2018, 06:09:15 PM
Cool thanks i have a habit of crashing!!!, the fuel design is simple. The fuel pot hoses the pump in the middle it pulls up loops back into the body that houses a filter and out of that into a fpr at 4 bar...(not 40psi as i think i said earlier got psi and bar round wrong way). It vents into tank and incorporates a syphon that pulls fuel over from the other side of the saddle tank on the 8.
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!!!! Scary Mary time

Ok cool, ill do that....

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?

Lol

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 me, I love old school stuff. And I do like swaps. But I dont like if some rapes rare car. Howerer,  I dont think Elan is that rare and iconic,  so I think you are good to go

Amazing fabrication stuff! Good job. Hopefully some day I can see her finished...

With that, chassis and engine,  that weight and weight distribution,  that car is going to be awesome

As for carb stuff,  I dont know nothing about turbos, ecus and that electrical stuff. And I started to do rebuild with all those stuff, so I think Im in trouble

I think Im more impressed that you managed to shoe horn that engine into a 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.

Hey Boosted

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 ..........

All the canister stuff can go. Just remember to cap any vac lines on the plastic intake manifold.
Mot wise...Elan is precat 92 so im 99% sure wont be needed. All the new regs ar 2006 onwards.
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.

Well Im hoping the Elan is tax free anyway lol ! The Mk1 escort and 1947 Chevy Truck were and they had engine swaps.

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.

Title: Re: Rotus Project Build
Post by: boosted on December 04, 2018, 03:03:59 PM
the decat looks fine to me it wont get anywhere near as hot as a cat...the cat it that position does concern me i think you'd have a fire. :angryfire: The radiant heat from the cat is immense.

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.
Title: Re: Rotus Project Build
Post by: Jamie R on December 04, 2018, 03:13:24 PM
Im in the same boat......

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,
Title: Re: Rotus Project Build
Post by: re japi on December 04, 2018, 03:27:41 PM
Jon had good point there, exhaust is super hot! Then, N/A rotarys are really really sentive about headers. Can compare 2stroke tuning, you can lose or gain lots of power with crappy exhaust...

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...

Somebody on rx8club said my exhaust manifold was rubbish! Dont know enough about exhaust tuning to disagree but if my straight out headers 1 bend each into a 3 inch straight through silencer is worse than the stock log manifold id be very surprised...
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.

That's an interesting point.

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:

As for headers,  I dont know much about renesis headers. But yes, exhaust ports are very restricting and narrow. So I would imagine that good flowing header is much easier to build than stock one.

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

Title: Re: Rotus Project Build
Post by: clive on December 04, 2018, 09:32:12 PM
I would say that you already have long enough primary pipes for good scavenging anyway. From memory Mazda found that really long primary before being collected made better top end, however to keep the engine tractable what you have is great.

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!   

Hope this helps

I think that exhaust pulses are really important in rotarys, as in 2 strokes. But for Renesis, you have to be math geniuos to figure out I quess. I havent seen any desent Renny DIY header tips. Well, just wing it, itl work  :great:

As Jon said, but yeah but no but  :13:

Dashboard update !

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.

Thanks Jarno!

When the steering wheel is on the right side, its on the RIGHT side lol !

My axle width is stock RX8 front and back, a little wider on the back than the Lotus and a lot wider than Lotus on the front.

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.

Fuel Tank update!

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'm about as good at wiring as I am at platting turds.

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 .......

Just a thought if you're struggling making the rx8 fuel pump fit... Mx5 mk3 is the same pump and same level sensor. The actual housing may be smaller. Also the rx8/mx5 fuel pump is the same as evo x and a number of other cars.

I'll settle for the ergonomics of floor mounted brakes and top hung accelerator like you have considering it all works.

Thanks for the heads up 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 ..................

Evening all,

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 think you gotta have to move it so can access from rear...youll dribble fuel all over your seat...need good access for a funnel when using jerry cans etc.

Fair point,

I can move the filler cap to the outside near the c pillar area ,

I may need to look at a flush aircraft style filler cap....... Just won't be in keeping with the aesthetics of the period look from the outside

Tried 3 different style brackets now, the boot is really low and close to the  top of the tank, it leaves the filler neck and rubber connecting pipe almost horizontal that I'm concerned the fuel will run backwards

Hey Jon, I hear what you're saying..........

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, 07:43:07 AM

Title: Re: Rotus Project Build
Post by: Jamie R on December 20, 2018, 07:50:21 AM
I need more coffee !!!

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
Title: Re: Rotus Project Build
Post by: Jamie R on December 20, 2018, 10:52:11 AM
This is a perfect example of rushing something.

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 .

Ive got the same filler neck, the rubber seal perishes or falls out, i wrapped the filler thread with PTFE tape now and no more leaks or fuel smells.
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.
Title: Re: Rotus Project Build
Post by: Jamie R on December 20, 2018, 03:02:35 PM
Due to how I need to make the bucks /patterns for the new wings ( I wont bore you with the details ) the existing filler hole is not an option, however I could open up the aerial hole and the inlet points in the right direction, the aerial hole wont be used for an aerial, and its further inboard.

But I still have a problem with height if Im not careful due to the curvature of the car......

..... I hate it! wish I bought a van ! lol

Well,
I have a solution.

Ive put some detailed pics up of the process below, just in case someone takes any inspiration from it and wants to create something similar, not just for a filler cap, but a recessed section in general.

So, new location, old filler cap hole filled up.

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...........

Title: Re: Rotus Project Build

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.

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.

Nightmare nightshift!!
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:

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?

FINALLY !!

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:

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......

Evening Jon

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?

Out of the office tomorrow, but you can still get me on 01474 777800, leave a message if I don't get to it quick enough.

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.

I'm out tomorrow, but I'll try to get some pics up on Friday.

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 running rx8 stylee return less. My tank houses the original rx8 fuel pot with inboard regulator. I have added a sytec filter in the engine compartment. Its ran in 8mm id fuel hose from pump to rx8 hard fuel lines. The original is hard shelf plastic pipe. If your careful you cant cut this off the rx8 coupler and attach coupler to 8mm fuel hose so it fits onto hard metal fuel pipes.

Afternoon all,

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.

Is this something you can buy, because I planned on using the original spec vent pipe which routes around the underside of the roof, and out the floor of the car
Title: Re: Rotus Project Build
Post by: boosted on February 11, 2019, 09:41:15 AM
yes mate its just a little shuttle check valve that goes inline with the vent hose.

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.

Cheers Fella,

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.

Title: Re: Rotus Project Build
Post by: boosted on February 11, 2019, 12:58:32 PM
Under i reckon as shown in photo...may be a little alloy cover over pump n filter to protect from dirt. Run the fuel line up the inside of tunnel. Over top of bell housing into fuel rail

Good decision,

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.

answers on a postcard, or just reply here lol

So laid up the centre console in the mould this morning.........

Looks like I've found a piece of furry road kill !! It just needs to marry up with the dash and get the gear shift cover to clip in nicely.

Title: Re: Rotus Project Build
Post by: Jamie R on February 21, 2019, 07:10:44 AM
Lol it's my own design.

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.

Yup!

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

Hi Guys,

Can someone just clarify the following

Measuring the toe in on the rear wheels........... does the below table suggest that measuring between the inner faces of the rim, at a mid point.....

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?

I dunno if any of that makes sense !?!?!?!

Mmmm you need Clive mate me thinks Clive recently advise me 0.15 toe in rear overall and  0.07 on each rear wheel on a rx7 fd as it moves abit on acceleration and turning forces.
The rear on an 8 is superior and does not wander as much so values gonna be less as a guide...till someone can give you exact figures...

I got a book on aerodynamics by Simon mcbeath...... There was a photo of an open wheeled car, the nose cone was full width so it created an air dam in front if the front wheels and helped with downforce......... Food for thought

Title: Re: Rotus Project Build
Post by: Jamie R on February 23, 2019, 06:39:12 AM
There ya go Jon.

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

If your traction is too great on the front end as a result and the tail gets loose, you can fine tune the front end, a cordless drill and a 2” tank cutter till you get the balance right lol.

Can unbolt it and make a less aggressive one if you wanna make it pretty lol

Sorted! now ya talking.

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...

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.

That work for you ?

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

Update......

Did this yesterday, never done this before....ever............. I just "wing" it  :-\ :-\

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.

Just spotted the suspension query. Even I was puzzled by this one because normally you would measure toe on the outside edge because if you measure toe from the inside edge, toe on the outside edge will become less  accentuated  .

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. ;)

Title: Re: Rotus Project Build
Post by: Jamie R on February 25, 2019, 10:00:37 AM
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.

Well I wouldnt choose SuperTrap for a rotary. Two reason:
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
Well I failed!

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:

On the second side, trying to match up the first side. I hate cars!

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.

Had some advice from Jon to have a break, ignored him (Sorry Jon), and cracked on and the second rear wing come out better than the first side.

The arches on the back have been bugging me for a while in terms of what car they remind me of.

Evening chaps,

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

I know who to see as the master of solid works when I want some more parts designing for the 3d printer, I normally end up making dummy thin wall prints for mocking up purposes before the main one.

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.

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
Title: Re: Rotus Project Build
Post by: Jamie R on March 30, 2019, 01:56:33 PM
Update...... so, Ive changed my mind...........again !

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.

Well the patterns have got to the next stage..... first few coats of primer flatted down.

Despite all the colour differences, its actually mirror smooth.

just goes to show when you think youve got a panel smooth with filler theres still highs n lows. At least my arms got a work out past few weeks, saved gym membership........

I wish I could just lacquer it now, but theyre a tad heavy lol.

Onward......next bit. Never thought id say i miss fibreglassing,

Ok so im trying to re-introduce some Lotus styling again to the wings, as I had to cut the originals off.

Had some 8mm solid bar rolled to the diameter of the wooden template, then massaged them to fit the curvature of the wing.

Bonded them on with some filler, sand, (bit more to do) and voila!

Radiused flares, just like the original wings!

Its the tiny details like this that finish it off

Again.....................these wing patterns!

Finished shaping the beading, last few coats of primer going on, flat it all down tonight and I could be making moulds tomorrow......about time!!!

Ive put the pimer on with a roller this time opposed to a brush as it took ages to sand the brush marks out. Spraying this stuff on is not an option at this stage.

The roller left a nice orange peel look. When I paint it manderin orange, shall I roller it on for that true authentic orange look ? lol

Ok Gents!

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

Oooooo ive not thought of 2 per side.......

Now THATS got the cogs turning

I was thinking 2 headlights per side like the 787b in the top right hand corner of this forum, so that could tie in nicely.

Jon, see any issues for a current, power, brightness, wire thickness, perspective running them 2 per side????

That sounds very suggestive 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.

Oh and getting resin my beard !
