Title: The other rotary Westfield!
Post by: Smiffers on March 18, 2014, 12:51:20 PM
Clive has managed to convince me I should get back on here and share my (not so) handy work over the last couple of years.

So I purchased Brian\'s Westfield a couple of years back (There is a thread about is some place on here) and the project is finally coming towards an end.  We hope to be out competing in Sprints and Hill Climbs this season.

I will find the time to write up some details but pictures speak a thousand words.

So it seems I cannot work out how to post pictures :(

Perhaps I need to renew my MRC membership before I can post pictures?

In the short term take a look here http://www.rivetracing.co.uk (http://www.rivetracing.co.uk)

Cool, Yours looks as comfortable as mine! Ill have a decent look through build when at home (at work)....What did she make on the rollers? Ecu std? any porting?
Title: The other rotary Westfield!

Those header look mightily hot!!
Title: The other rotary Westfield!
Post by: Smiffers on March 18, 2014, 04:26:18 PM
The ECU is a universal Adaptronic unit - 440D.  My own porting has been performed on all the intake and exhaust ports but nothing exotic like the aux bridge on your engine.  I have done all the work myself so was not brave enough to experiment,  I think that is best left to people that have a clue what they are doing!

I have a problem with the engine, an oil control issue of some kind.  I can\'t get to the bottom of it but have been focusing on all the other things like the daytime MOT that it passed at the weekend :), body work etc.  Ultimately that engine problem stopped the tuning on the dyno but we did see 205 FWHP at around 6500rpm before we called a halt.  As I\'m doing the tuning myself it has been an expensive learning curve as the dyno hire costs £££\'s

So I\'m going to get it road legal and do some of my own testing to narrow down the conditions that cause it to consume oil and then enlist the help of Carl.  In fact Carl has been kind enough to talk me through some fault finding already but that has not turned up any obvious fault.

Been out in mine running it in....i have a daytime mot! Youll get lots of waves and thumbs up! Hope you get the oil issue sorted.
I may go adaptronic next year but no money in budget this year...and it looks like im gonna have to pull the diff for a rebuild. Defo duct in the rad and oil cooler will help keeping temps in check.
Great to see another .
Title: The other rotary Westfield!
Post by: Smiffers on March 18, 2014, 04:52:25 PM
Yes they do seem to get hot; it is a point of contention currently as I can\'t work out if that is too hot and there is another issue.  That photo was taken under atmospheric load with the dyno holding at sites between 4500 and 6000rpm so the engine is working very hard at that point for sustained periods.

When I get back onto the engine I need to double check the timing as a very retarded timing will give you that pleasant glowing result (or very lean mix but that would be more obvious through the AFR data).  I manufactured the headers from pretty thin stainless so it could well be the case that they just have a low thermal inertia so heat up very fast.

The problem is that the renesis does not have any timing marks I can find so I will first need to go and make some graduations on the pulley and a pointer on the front cover to test.

Well if your running in can stretch to the Reading area then you should come and pop in for a visit, I do a good line in tea and cake!  If you do choose to go Adaptronic then the good news is I have done all the hard work for you!  Although if you go Adaptronic plug and play you can piggy back the standard ecu and get ign and fuel control, I have gone standalone but have still kept all of the intake control working as Mazda intended.  The only thing I have dropped is the FBW throttle, which gives me ignition only idle control but that works fine for a race car that you warm up before driving.

If I go turbo I will have a look at the FBW again as that can provide some interesting antilag options :)

Ive been to Reading junction Saturday ! and Oxford junction Sunday!!! Ha i was gasping for a brew! Are you monitoring your oil temp? Just wondering if getting real hot and thinning out and defeating seals. At present im running 82 coolant 76 oil but have not been over 4000 yet. Last engine my oil hit 115 on track and when i fire back up after lunch i had 5 secs of smoke ??? Just a thought?

I\'m inclined to agree that this hypothesis is the most likely candidate.  Oil temps hit 130 on the dyno and may well have taken out the seals.  Will be good to get some on road testing done so I can understand the problem before I pull the engine again.

Previously my old  spare engine smoked badly on a track day as im in contact with the previous owner. He thought the engine was subsequently fubar and sold it...2 owners later i buy it after its been raced last year in a double header and engine still fine so hopefully if you can get oil temps in check hopefully ok. If the oil control rings where gone it would smoke all the time i imagine. Get out on the road with decent airflow see what temps your getting and any smoke? May have just had oil thinning and blowing by seals. Does she smoke all the time now? Ive set an alarm on my digi dash to 110 deg C .

Post by: re japi on March 19, 2014, 03:33:28 AM
Looks great! And that header seems to be quite hot :) Well, I think that 205 FWHP at around 6500rpm is quite good numbers. :)

Good job
Title: The other rotary Westfield!
Post by: boosted on March 19, 2014, 09:04:55 AM
I see your oil cooler is behind your rad. Rx8 and rotary 1/3 of engine cooling is done by the oil, I am really hoping your engine is fine and just seal blow by due to heat.
Personally id put the cooler in front of the rad and duct the 2 in and seal the back of the nose cone so all air entering nose cone has to pass through the coolers. If ive still a cooling issue either coolant or oil i intend to mount a smaller motorbike rad and oil cooler in the space on the passenger side of engine with a duct. This would increase oil and coolant capacity and allow more heat to dissipate......But i\'m hoping my ducting works first as dont want the added weight!   Ill find out saturday!
Title: The other rotary Westfield!
Post by: Smiffers on March 19, 2014, 10:18:12 AM
I agree with you, in fact I have already added a sealed shroud to the oil cooler which will be ram fed air from two ducts on the chin spoiler via 2 76mm neoprene hoses. I will then duct the rad to the nose opening and see how that works out for temps.

But yes I should have invested some more time working that out before I started the tuning process, lesson learned!

The bonnet is a one off to clear the Renesis but still allowing me to run a complete flat floor from splitter to diffuser (There is no engine below the bottom chassis rails).  That one is in glass but I may well lay one up from the mould in carbon once I have proved the fit and clearance etc.

It is a wide bodied car, the scoop is completely custom but based around the contours of a V8 bonnet.

It would be best to give me a ring to talk through things if you were looking to do the same.  Do you have an email so I can send you some contact details?

A good couple of days and a great end result.

I ground out the bonnet air scoop and fitted some dzus fasteners to the back shut.  I\'ll get some pictures up of the finished bits and bobs but in the mean time the end result was this:

I only went a couple of miles down the road and back.   It is the first time it has been on the road so I just wanted to see what was going to fall of or catch fire!  The only casualty was one of the bolts in the aeroscreen.  Seems I needed a support in the middle of the screen.  I turned up a little nylon bar and broke out the double sided tape, et voila!

Also on the move I could not notice any large amount of smoke from the exhaust,  I think I need to try a long hill descent under vacuum and  then back in the power, like the old test for worn valve stem seals on a piston motor.

Thanks Brian!

At the time I descided I didn\'t need the aero bits and bobs but now I\'m running out of things to do and missing them!  I\'m worried that when I have run out of things on the \'to-do\' list I may actually have to go and compete in it :)

Off to the get all the geo and cross weights done tomorrow, then maybe Abingdon on friday for a shakedown if I\'m feeling lucky.

First event will either be Gurston Down with the WSCC on the 26th or Dimanche with your crowd at FDMC, which reminds me I must sign up for a membership!

Thats great mate! Thanks if things dont slot into place i may take you up on your offer. Basically brakes are fried on trailer and ive just sold my van( too small)! so hunt is on this weekend for a more suitable tow truck and if time work on the trailer.

This friday Combe still has places on there own trackday, i\'m seriously tempted but need an airfield circuit first. Engine wise its as far back as i can go and with a shorten of airfilter pipe should tuck under bonnet as well. Been looking at humps power bulges seems loads available...hoping toget time at work tonight to fab up some engine mount spacers.

Hi Mate, have not seen yours for a bit. Hows yours progressing?
Title: The other rotary Westfield!
Post by: Smiffers on May 19, 2014, 10:11:05 AM
Sorry!  I forget to keep the world informed at times...

Had a great breakthrough this weekend!  More on that in a moment...

Corner weights and geo all done 530KG wet (Full Tank),  very good experience with the chap that did it for me very happy with the weight as contrary to popular belief the rotary is not the lightest engine gearbox combo around (although the weight is all in the right place).

Took the car down to Stoneleigh as it was being exhibited there, very well received and a great weekend.  Gave some needed motivation!

Then the breakthrough; I have been fighting with a issue with the car as it approaches the APV operation point around 6500rpm it just would not get passed the transition point.  Now I\'m running a standalone ECU (for which I have had to map from first principals with zero previous experience) with all the intake valves and I have manufactured a solid state APV motor controller myself, so naturally I was looking at all of those problems and not opening my eyes to some traditional fault identification.  So at the weekend trying to work it all out the problem got worse to the point the car would no longer cruise at low rpm.  Limped home lifted the bonnet and notices the the fuel pressure was bouncing about a little and the pump hunting, checked the MAP and that was rock solid...  Maybe I should check the fuel filter and non-return valve...

And there we have it clean the fuel filter reassemble everything and my fuel pump is super quiet and the fuel pressure bang on the money.  Take the car out for a drive and apart from the fueling being all over the place at many points I can easily rev all the way up to the red line with all of the valves, three stage injection and APV working at Mazda intended.

So now I just need some tuning time and we are done :)

To say I am pleased is the understatement of the century.

Post by: Smiffers on May 27, 2014, 01:09:09 PM
Yes, we are going to do a simple test with some rendering on low res video on the pi.  But my day job is broadcast so we are also going to play with some 4k capture for demo material for the business.  Unfortunately the Pi will not be able to chew through that!

Good progress this weekend.  I can now read Adaptronic ModBus and Race Technology serial streams and write them to log files...  Have also worked out the dash button press messages so we can add markers and start/stop the logger.

Progress I tell you!

As part of the process I also made some progress tuning, things are getting better.

Noted some performance from the logs.

3.2sec 30-70 - Uphill, pig rich and with very conservative timing...  This thing could be interesting.

Although I am a little worried about my gear ratios, I cant imagine using 6th or 5th for that matter.

What final drive have you got?

4.1 at the mo but jury still out on whether i swap out to 4.7...At combe used 3rd and 4th on all the corners and 5th on the longest straight. But i\'m swapping to 13" and slicks so gonna decide after ive seen the gains with that. hill climb your gonna be in the lower gears i found 5th to be taller than 3rd and 4th but tbh ive never been over avon rise that fast before and my right foot was lifting...

HI mate, can i ask your front and rear offsets, brake set up front n rear pls...also what tyres/wheels width etc...i know your widebody and im narrow bod...but just checking my maths and measuring right!
Title: The other rotary Westfield!
Post by: Smiffers on June 11, 2014, 11:18:07 AM
Sorry chap been overseas wrking for a few weeks...

Do you still need all the info - I will go do some measuring tonight...

The big numbers are 13x10 on the rear 13x8 front (I use compomotive minilite style wheels, can\'t remember the model), I use the ali cortina style uprights (siltech) in the front with M16 style 4 pot (Raceleda R-16) on non vented nothing special disks.  Westfield ali \'race\' (No handbrake) spec rear brakes (these are re-branded hi-spec calipers) on standard sierra cosworth rear disks again solid.  Running Girling master cylinders (Which are worth every penny after the :censored::censored::censored::censored: wilwood alternatives, I had two fail) in sizes I will look at later, standard balance is very good with the bias bar in the center.  Pads are personal choice so I will stay out of that conversation, most of them work as long as you put them in!

Remember you do not need to go big and fancy with a 500kg car the weight of the assemblies will gain you far more advantage.

I\'m off to Abingdon on the 20th for a shake down and some top end tuning work if you fancied it?
Title: The other rotary Westfield!
Post by: Smiffers on June 11, 2014, 11:37:58 AM
I should also add,  low speed mechanical grip is super important in hill climb and there is a huge trend for super wide wheels and tyres at the moment.  This comes at a cost of increased un-sprung mass, which in turn requires smart management through expensive damping.  For circuit where lap after lap consistency (in my mind this relates heavily to how compliant the car especially given lower level of experience with a particular platform) is of the up-most importance.  For us mortals with smaller budgets I would probably end up with 13x8 rear, 13x7 front if I had my time again and had not inherited the wheels with the rolling chassis.

Waiting on suppliers...to make the wheels! going 13 x6 and 13 x8 compo motive or team dynamics 13 x7 who ever makes em first! Will get the former for next year. Sussed my offset need a et23 for 7j.

number of geo guy would be great though mate.

got a pesky oil leak atmo so not a lot happening.

thanks Jon

Jtech - 0118 947 9555

Ask to speak to Jamie and tell him that Jonathan with the rotary Westfield put you in contact.  I don\'t know if you have a base setup in mind but you are welcome to mine once I have tested it on the 20th.

All the best

Jonathan

Oil leak sorted by Carl and the guys at Hayward. Too much premix. Carl spotted my air filter is 2 small so thats off using gauze at mo...car is flyin...a4 on way home much fun....but so bumpy broke the rivets on the rear diffuser...so had to take it off...how do you transport it in a westy...had to fold in half.
thanks guys big time !

So in general Abingdon went very well, car made it through the entire day :)

Some positives...
The base handling setup was very good, couple of clicks on the back as the car tended to wash out under acceleration. I may add a little more front negative camber but I will test that synopsis by measuring temps next time out as it is marginal.  Limits felt very neutral when reached.

Some things to work on...
Cooling - 100C Water 120C Oil after three hot laps.  Going to move to a larger cooler 25 row and duct the radiator into the nose.
Gearing - I was hitting 125mph and not getting out of 4th given the aero on these cars limits to about 150mph tops I seems those other gears could be put to good use else were!
Fuel - Fuel surge issues, right handers are great left handers high G car cuts out.  So 50% perfect!  The down side is that when the car cuts out it gets very unbalanced and increases the work rate of the driver considerably...  It is like anti-traction control.  I\'m running a Bosch 044 pump and apparently they are a little sensitive to the head of pressure on the input side to the pump so I have a few options:
Increase the low pressure side pipe diameter to AN10 (From AN8) this gives a higher mass flow rate potential on the low pressure side of the pump (AN8 High Pressure side).
Move to a surge tank + Lifter Pump system with the surge tank mounter high above the 044 pump.
Try a different pump.
Try a different tank setup.

Car is getting ready. There is allways some minor problems with new cars. And you allready seem to have cure for you little problems. :) Its allways a good thing when you know what to do...

So next time your car will be more complete

But you made one mistake, you didnt share vids or clips with us ;)

Hi mate.

couple of things

1 have you filled your fuel tank with baffle foam ..in expensive and serves to purposes..anti surge and explosion safe....my tank is brimmed with it.
2 on the roadgoing rx8 there are 2 oil coolers i had this prob and the addition of 2 has increased oil capacity and temps in this recent hot weather for oil have been under control...you have to buy another oil cooler you may as well plumb in 2.
3. Gearing yes think we both need different diffs..im on 4.1 atmo prob going to 4.7 but holding off til slicks are on and see what its like.
4. Since i ducted in my nose coolant temp again seems sorted recently at Carls drivung the car hard temps got to 98 when lost ticking over and soon as moving ducting brought temp right down.
can i ask if you left leg got hot as all that engine heat has to go somewhere....im going to drill 3 large 80mm holes in rear tub to evacuate the hot air....yours is completey flat and plated underneath so that hot air has togo somwhere.

br Jon

1. Yes tank is brimmed with it, I\'m going to go with a swirl pot fed with a low pressure lift pump with a low pressure valve in the tank return. This way I always have a few psi of head pressure regardless of tank fuel remaining also makes it easy to swop between tanks without a change in fuel delivery characteristics.
2. Indeed I think I will copy you!

All of me gets hot!  Yes it does and yes I will be taking the hole saw to the back

lol yes...my eyes are shaking so much! My seat back is high and i put the back of my lid onit.

First race my screen misted up open the visor slightly not good dry eyeballs lol!

All good fun though. Got Coombe monday for more testing so wil see where we are after that.

Re japi...foam is fia approved so should be ok.got from Merlin Motorsport over here and fully trust them. They would not sell it if melted also listed in Demon Tweeks so good stuff.

Well, it was about time for an update...  Been a busy year but I am now happily married so there are now no jobs left before this car gets prioritised!

So when I left you last time we had some fuel issues, oil burning issues and temp issues out on track.  In no particular order these are some of the bits to make that better and some new little bits I have been working on to make the car a little more 'professional'.

The fuel system got a complete make over.  I welded up a custom Ali cell to sit above the diff and feed a swirl pot mounted in the original tank position.  Swirl pot is fed by a lift pump (Red top) the swirl pot in turn feeds the 044, return the swirl from the regulator up front and a return from the swirl back to the main tank.  The idea here is if I am circuit racing I have enough fuel onboard for the duration, for hill climbs I can just use the swirl pot capacity (plus a little to give it a head of pressure).  Here are some pics of that handy work.  First go a tig welding Ali so a little ugly I'm afraid (but fuel tight and made to fit).

The oil burning never got sorted with any non-invasive options so engine has been swapped out for a R3 engine I had knocking around for spares...  Turns out the 300 quid ebay engine is a lovely little runner...  I lucked out big time, had to do a few things to get the R3 changes intergrated but nothing an afternoon of fabrication and head scratching did not sort out.  I have the map roughed out to get it running and took the opportunity to scale the new map to 200kPa (just in case) ;)

Cooling has been upgraded, much bigger cooler is in and ducted into the front splitter, radiator has a hermetically sealed surround to the nose cone. Hopefully that will sort us out, if not I have also made provision for a second cooler behind the rad.

Also been working on some nice little changes to improve things a little and fix bodged brackets and such like...

First was to enable the fitment of a little denso 40A alternator to gain a little space up top (this is related to my 200kPa map).  So I got the CAD out and went to work on on an alternator adjustment bracket to let me fit it.  Also added some Rivet Racing branding.

Here is the prototype for that, some tweaks needed to be spot on but works very well.  Yes the alternator is tiny!

Finally been working on a nice solution to holding the AC Delco (LS Yukon) coils I have been using, another work in progress.  Should have that finished this week.

Good to see this progress Jonathan and your now married, congratulations  :bravo_2:

A word of warning about the alternator, check your voltages on slow running as I ran a Walbro as a lift pump with an 044 and a 40amp could not keep up with the draw from the pumps.

Keep us posted on this great build  8)

Excellent mate, nice fuel set up....i do think that 2nd oil cooler will be needed. My first 1 was in the nose before the rad and still is but now i have a 2nd 1 mounted on passenger side. yep keep the update coming!

Thanks guys for the support, will try and keep the progress going over the winter for a season next year (I keep saying this)!...

Clive, you are correct, I don't think that alternator will charge at all at low revs, I'm banking on the fact that I have a small battery to deal with warm up and such like...  The rest of the time I don't plan to be near that end of the rev range ;)

Jon, yeah I think I know I will need a second one (you keep telling me after all) just have not quite got around to excepting that yet,  I'm sure that will take care of itself at the test day next week!  What size are your coolers?

Post by: Smiffers on December 09, 2015, 10:47:32 AM
One other question...

Does anyone know of a good way of getting an oil temp sensor into the R3 any place?  The normal filter sandwich plates do not fit due to the relocation of the oil system to the front cover, anyone know of any good solutions, the rest of the system is AN10 fittings...

I'm trying to avoid dropping the sump to weld up a boss.

OK so we have got everything back together tuned the idle for the new primary injectors for the R3, bumped the base fuel pressure to 450KPa from 380KPa as that made the idle easier to tune (Better atomisation at higher pressure?).  So I now have a 850rpm factory idle from warm up all the way through to operating temp all with ignition only PID control of the idle speed...  Result.

Booked into Llandow on Thursday for a general testing day to see if all the changes have worked!

Title: Re: The other rotary Westfield!
Post by: Smiffers on December 19, 2015, 11:45:39 AM
Okay, time for an update on the test day at Llandow.  First of all I ran out of fuel before I ran out of talent so that must be good, leaving with empty fuel cans and everything else the same shape as it arrived is always the sign of a good days testing.

It was wet, not just a little but full on monsoon wet, even with full wets it was a lot of fun trying to keep it between the lines.

We started the day with a little scare, sighting lap, half way through the first warm up lap....  Oil Pressure alarm...  Engine off, towed off the circuit fearing the worse.  Turns out the sensor interface SSI-4 (0-5v to serial) was intermittent, rather than packing up with no pressure alarms we made the foolish decision to carry on for the day in the knowledge that if both the fuel and oil pressure were reading 0 it was likely a false positive!  We got lucky, not the recommended best practice approach guys!

Made loads of progress with the fuel map on the new engine during the day, a little more work to do at the top end (I'm also suspicious of a weak 044 pump but have no evidence due to the fuel pressure sensor problem) a we had some intermittent misfires over 8k but only in 3rd and more in 4th (4th is top for me as the diff ratio is all wrong!).  Need to check some logs on that over the weekend, the other possibility is that at high 90+ MPH there is some ram air effect into the intake causing the MAP to move to the 106kPa row and over fueling, will do some digging through logs.

The final drive ratio is still wrong (but we all already knew that!),  I'm going to order a 4.7 CWP set and rebuild the diff over the winter).

Cooling was good for the day, MAX 93C Water and 85C oil...  It was a cool day though and the amount of water going through the front of the car probably helped keep the temps down.  So for the time being I'm very happy that those changes have at least made a good amount of difference, will keep an eye on that as the ambient temp goes up and in dry conditions.

New engine seemed great, did not miss a beat all day (apart from the map work) so as a back of the garage ebay parts engine it has excelled in its new role!  So this gives us a working platform for events this season.

Jobs to do:
Re-work the loom (it has grown organically during the build and the sensor interface issue was the final straw, it need to be robust and simplified)
Swap out the 044 for a new one (it has taken some abuse over the various fuel problems and is a cheap test worse case I have a spare)
Swap out the non-return fuel valve (the car has never held pressure key off, I have not had any vapour lock problems but I would at least like to know why it does not do that)
Rebuild diff with 4.7 CWP
Swap the fuel pump switch for relay controlled from the ecu, one less thing to worry about and simplified the wiring (ask me how I know you don't want a fuel pump switch too close to the gear stick!)
Remove the dash box - now we have all the warnings, switches on the dash or automated from the ECU the box now only holds the master switch, ignition and start button.  They can have far shorter cable runs and be better placed on the PAX side of the transmission tunnel above the battery.  Again my new push to simplify everything!

So that's it...  I have no idea about lap times at Llandow but we were running in the 47 sec area in monsoon on full wets of the timed laps I was bashing out all the laps withing a couple of tenths so I was happy with the consistency.

We are planning another trip in Jan once we have got a few of the jobs done for some more testing and to test some of the fuel assumptions.

Post by: Smiffers on December 19, 2015, 08:09:40 PM
working out the sensor problem has opened up some more questions...

So the power feed to the SSI-4 was the problem, looks like just a loose spade at the fuse box.  But that same fuse also powers the APV (Aux Ports) motor controller, so it would seem that when the sensors failed so did the use of the AUX ports, which maybe explains the intermittent miss fire at high rpm as well.  I think I will still have a little look at the fuel pump but at least next time I will have got rid of another variable and will have fuel pressure logging back to diagnose the issue properly if it still exists.
Title: Re: The other rotary Westfield!
Post by: clive on December 19, 2015, 09:33:55 PM
On  the 440 Aux output 4 would normally be the output to operate the  SSV (secondary side valve) is this what you using ?

If not and your not sure of it working then it may may be an idea to fix this in the open position as a test because this would give the running out puff condition your describing.

Its also worth knowing that if you want the map looked over  then mail   tech@adaptronic.com.au  as I know they will be happy to help
 
Title: Re: The other rotary Westfield!
Post by: Smiffers on December 20, 2015, 09:52:20 AM
Yep that would be another candidate for suspicion for sure.  In this case it must be the AUX ports as I have to use and external DC motor controller (The 440 does not have any support for servo control) the motor controller I made is powered from the same source as the sensor interface so as one was not powered neither was the other which would mean no aux ports in operation.

Not to say it could not be both!

Hopefully a simple one this time!

Thanks Clive

With Rotarys needing to gain much more cooling from the oil system than a piston engine, first question must be, what oil coolers are you running?

Problem was more fundamental, incorrectly installed thermal pellet replacement thingy...

Low flow through shaft leading lo the localised heating.

The spring that holds the thermal pellet was also installed...  It is not needed.  In itself that would not be a too much of a problem, unfortunately it was installed on the bolt side of the pellet replacement holding it against the opening of the eshaft, restricting flow. Lesson learned...

Title: Re: The other rotary Westfield!
Post by: Smiffers on January 14, 2016, 11:16:00 AM
It was already ported, side plates had some wear as I had lapped them but not re-nitrided them,  they are paper weights now, I knew that was going to be an issue but was interested to see what the wear rate was as this engine was always a test mule.  I have a new engine I have been building up that I have re surface treated the side plates so that should avoid that problem next time around.  Rotors are good (new bearings needed), rotor housings are fine as well (plenty of oil for them!).

I'm not too bothered a simple mistake that I wont make again, this is how progress is made.

Manged to pick up a cheap bosch 413 (It's the bosch motorsport version of a 044) from a motorsport team sale and a new one way valve to see if I can keep the fuel system pressurised pump off.  Apparently it was part of a fuel system for a Saleen GT car, not sure I'm going to be using it to it's full potential #overkill !!!

Got the extension on my steering wheel to move the wheel a little closer to make it a little more comfortable...  Need to see if I can work out a way of moving the gear stick another 20mm towards me.  How did you handle the gear stick?  I seem to remember that you engine is alot further fwd than mine.

Ordered all the pre-requisite number backgrounds, novice sticker and so on to meet blue book.  Need to make my detachable timing strut this weekend so I can switch between sprint and circuit mode.  Had a chat to the local scrutineer (turns out he lived just over a mile away!) he is poping down to take a look over the car from me, also found the car has a MSA log book already so just need to send that of for a number of ahem small updates.

Most of the loom stuff has arrived, so I will have to start that job at some point (not looking forward to that) but it will solve the electrical gremlins.

Oh and I need to get the diff out so it can go get its new CWP,  that is a Feb job though.

Might sneak off for another test at the end of the month once the new fuel bits are in to see if we have solved the top end splutters!

Oh and I need to order two sets of slicks, one super soft for sprinting and one not quite so super soft for circuit work (ouch).  What size, compound did you go for?  I'm assuming you went radial slicks?  I know some of the light stuff still sticks with crossply for compliance, seems a bit old school to me?

1. gear stick i put a Set in it. ( right bend straight then left bend). soz just incase you dont know what a set is...got a gearstick extender from ebay with correct thread and heated it up and bent...got 2 i done happy now. slightly longer throw but closer to steering wheel.

2. Tyre yes radials Yokohama a005. 200/580/13   meduim if my memeory serves me correct. mine have had little use nearing 2 years old now...immense grip when warm.....and oil surge! between centre iron and plastic filler pipe there is a flange... put a penny washer in there...makes filling up a pig but stops the oil washing out of the sump on right handers.

The gear stick make sense, I really don't need much as it is only 3rd that is a little bit of a push, maybe I will try for a bend in the end of the standard lever and then a small extension to bring it back a little...  I'll take a look at that.

I'm running 13" compo-motive minilite's...  13x10 at the back 13x8 up front IIRC...  I don't have any caliper issues, M16 front calipers and Westfield (HiSpec) rears.  What are you running that is so tight?  Do you use vented disks?

Thanks for the heads up on the slicks.

Title: Re: The other rotary Westfield!
Post by: Smiffers on January 14, 2016, 03:44:49 PM
So in the centre plate the is the oil fill hole (a short round pipe with two threaded holes either side), that bolts to a (in the case of the RX8) plastic filler tube that puts the oil fill in a (not so) handy place to aid getting oil into the engine (it also has a breather).  Put a washer between the two parts to restrict the oil travelling up the fill tube by restricting the size of the orifice.

Does that help?

Penny washer might be a very British word...  Large flange washer/repair washer?

Re japi..filler tube on centre iron 2 bolt flange joins to plastic tube that runs under inlet manifold and then up into filler cap...can hold alot of oil . At this flange there is a little recess for the seal so adding penny washer or suchlike its captive here and oil coming up at force under surge is held back...not a hint of oil in my catch tank after fitting. Downside is takes ages to fill up with oil. Ive know got a rubber bush from an fd rad mount in there now but original was a penny washer.

When you top up oil wait abit...takes awhile to fill. Oil surface tension an all that. When i change oil ill take out to fill sump.
Title: Re: The other rotary Westfield!
Post by: Smiffers on January 14, 2016, 04:24:33 PM
While we are on the subject of oil, do you just use the single breather position on the filler neck?  It dawned on me that if the pan was vented on both sides you could never get the positive pressure to push the oil up the filler tube as it would be vented on the other side?

In this way you would not be restricting you breathing potential?  Not a problem for us NA boys but maybe of interest to Clive and the FI boys with the additional blow by?

Just thinking out loud...
Title: Re: The other rotary Westfield!
Post by: boosted on January 14, 2016, 04:35:10 PM
Yes just the 1 on the filler. My new sump has a turbo oil return but again only on left side. Have not tried this sump in anger yet. Damage to my bearing was done before the washer mod. Done a few track days on slicks fillling the catch tank with no pressure alarms going off. I also got an fd oil pressure reg from Clive... much better pressure than stock....thermal pellet in a drawer i couldnt get bolt undone on my spare engine in car. Broke the knuckle on the breaker bar and gave up exhausted
Title: Re: The other rotary Westfield!
Post by: Smiffers on January 14, 2016, 04:37:23 PM
The more I think about it we should be breathing two points in the sump (one on each side)...

The washer solution is a novel idea and I can see it works, but it seems a patch?  The oil will still be traveling up the filler tube under positive pressure once it covers the opening in the sump, when it meets the washer the flow rate is decreased (pressure increased) and this buys enough time for the corner to end so the oil never makes it out to the catch can.  But during this time the although the major issue is solved we have stopped all breathing to the crank case and would see an increase in pressure, this would be worse in a FI situation for sure?

Imagine the case that both sides of the sump were breathing, in the case the oil covers the fill tube the other side will be open to atmosphere and provide the path of least resistance for the positive pressure, this would mean the oil would not travel up the oil filler at all, the same is true for cornering the other way.

So to solve this problem and prevent other undesirable side effects I think we should vent both sides of the sump...?

Thoughts?

PS - Not shooting down the washer solution, I think it is great, just trying to make sure we all end up with the correct solution to the problem.
Title: Re: The other rotary Westfield!
Post by: boosted on January 14, 2016, 04:43:22 PM
Yes i agree. I dont think problem has been highlighted before as the rx8 cannot corner at the speeds we can generate. Thinking out loud screw a banjo fitting into sump plug and run a steel pipe upto catch tank....breathing both sides.

Title: Re: The other rotary Westfield!
Post by: Smiffers on January 14, 2016, 04:49:27 PM
Hmm yeah, although you want is as high as you can get it.  My worry with the sump would be that you may get into a situation where you have covered the oil filler but still covered the sump plug so we are back to stage 1.

For Clive the solution should be simple with the FD engine...  As he is single turbo he must have one of the original oil drain (from the FD twin turbos) points not used, that would be perfect for the breather as it is right up the side of the block... perfect solution.  So Clive we have you sorted!

I wonder if those blanks exist on the RX8 castings and could be drilled (would have to drop the sump to get it done as to avoid swarf in the oil?  Also I think my R3 has an additional 'wing' on the side of the sump that could be used.

I'm going to take a look tonight and report back with ideas.
Title: Re: The other rotary Westfield!

Post by: Smiffers on January 14, 2016, 05:42:12 PM
Yeah, I worry that he will solve the oil surge issue but introduce an oil leak issue due to a pressurised sump!  It is going to be worse with the FI motor than our NA.

I'm sure he will see our ramblings today though.  Will report back tonight on a plan of attack!  I must say it is nice discussing these things rather than stewing in your own thoughts!  Together we will win! (or at the very least get to the finish - LOL)

It's a date then!

So this oil breather... As expected the FD is a walk in the park using the turbo oil return...  Our exhausts are in the way though!  Three options for the R3 two for earlier and only one good one.

1.  Tap the sump.  Will be below the oil fill so would need a large breather to be able to empty the oil fast enough to breath before or as the slosh seals the filler tube inlet.  Not great.
2.  R3 could go into the sump extension wing from above.  Only slightly better the option 1.
3. Into the front cover, there is the perfect spot...
(http://i1362.photobucket.com/albums/r687/jonathan475/image_zpsrqymujp7.jpeg) (http://s1362.photobucket.com/user/jonathan475/media/image_zpsrqymujp7.jpeg.html)
The slightly cleaned spot bottom left, nice and high and almost as far over as possible,  will try to weld a fitting onto that scrapper to check there are no gotchas (I hate tapered threads into critical things so will do a weld on AN fitting, could do a simple push fit also).  Will check it works but if it does should be able to do it engine out with a dropped sump only, no need to remove the front cover with some careful ting heat management.

Personally, If this being mounted in an oil line I would say this would restrict flow.

I would look at either a filter adaptor or a boss welded onto the side of your after market oil cooler.

p.s. running the one cooler it would also be an idea to either mount a second cooler or a much larger cooler ( I used to run a cooler your size on my 4 cylinder cross-flow race engines but your Rotary needs much more cooling)   

Hope this helps

The first pic is the fitting that I'm not using for the reasons you say.  The second should work as the sensor will be in the side tee.

No filter adaptor will fit the R3 engine...  I plan to put this fitting on the oil cooler.

Post by: Smiffers on January 15, 2016, 11:17:53 AM
Clive did you see the notes above about breather positions to stop the oil being pushed up the filler tube?

Really think you should add a second breather on the other side to avoid the problem properly.  Is an easy one for you to add as well to one of the old oil return points.

Well some progress on jobs and some issues...

Swapped out the one way valve on the fuel pump, no pressure held even though old valve did seem to have issues.  Swaped the pump as well for the 413 Bosch Motorsport unit 10psi more pressure static, still no pressure hold.  Interesting that either my 044 was tired or the 413 is just so carefully selected that you get better performance than the 044 it started life as.  Either way reset my 60 psi base pressure. Scratched head some more.  Then came across a post on the turbosmart forum that says turbosmart fpr's don't hold pressure pump off...  Well I'll be...

Put some roll cage padding on to meet the blue book helmet contact rules, that went well!

Put a novice sticker on, also went well.

Tried to put a number background on the nose, went badly, number background in bin, tea needed.. Job for another day when missus is not shouting about inappropriate use of hair dryer.

Put some anti-freeze in the coolant as the temp is dropping (I don't think anything would freeze in the garage but better to be safe ehh).

The had a look at the oil fitting.  Turns out the adapted tee is made of some unweldable aluminium, which is common for the readily machinable alloys, Ho hum.  Next plan, new tee tap for m14x1.5 turn down on lathe and use m14 to 1/8ntp adaptor.  I will make this work!

Second time lucky with the oil fitting.  Just the tip in now, that should work well me thinks.

Process was..  Cut top tee down, m14x1.25 tap the centre and then an M14 sump plu adapted (the kind you would use for mounting a temp sensor in the sump).

Engine starts off so easy to work on and then the more you cram in the harder it gets....i still think the engine in a westy has better access to the oily bits than in an actual rx8! the only place left for my 2nd cooler was down left hand side...luckily there was a blanked hole for exhaust exit of a previous engine that i stuck a naca duct over and some ducting done the trick...your a fair way from Merlin at coombe but i found them really helpful. so much easier than trying to pick fittings from a catuloge...i stuck some bits on the counter and they went out of there way to help. an oil thermostat  would help mine takes an age to get up to oil temp....but alas no room left. :P

keep up the good work!
Title: Re: The other rotary Westfield!
Post by: Smiffers on January 27, 2016, 02:01:37 AM
Due to miss ordering of fittings, I think I have more stock than Merlin!

Working out in Singapore this week so getting frustrated I can get stuff done; thinking about the cooler I was wondering if I could double the height of my cooler to a 40-50 row unit and then graft two 20 or 25 row cowls together to feed it air from the front splitter...  That way I can fit everything in the same place and the current hoses 'may' already be fit for that purpose.

Ok so had a look at the gear stick...  Throwing caution to the wind I took an angle grinder to it see what the big black fat it was that would not let me bend it...  Turns out it's a big rubber bush, vibration isolation I guess.  So I chopped it all up and now I have this...

I was going to get the oxy out and bend it back towards me, but the reduction in height has effectively reduced the throw and so I'm not stretching as much now.  I'm sure I will have changed the feel now so I'm going to see how it works out like that.

Nice vid sounds just like mine!  Have not been back to llandow for years...

I cancelled Abingdon as waiting on another op and currently signed off for 2 weeks with kidney infection. gutted.

Post by: Smiffers on February 16, 2016, 04:49:59 PM
I've tuned out all the flames on over-run, not so much fun but less fluffy when you get back on the power.  There are some small blue flames between gear changes every now and then and some little flashed on over run (there is a small one in the clip along the straight).  I might actually put a little more fuel in on the over run to help with cooling.

I wish you a speedy recovery!

Thanks Clive,

Maybe shoot me an email with the specs for turbo and explain a little about how it has gone together.  If you have any data from MSP installs please share that as well, spool time, boost through the rpm rang etc. I'm weighing up a few possibilities for next season so would be very interested.

Sticker is my pleasure, you (and your business interests) have played a fair part in helping this all come together and I'm sure will continue to do so...

Always appreciated.

Looks great  :)

Did any issues crop up, and how did she feel on track?

Oil got a little hot ;)  It actually will be fine for the sprinting and hill climb that I'm going to start the season with but have also ordered a 40 row setrab cooler (it is a monster!).

Other than that mostly good, struggling with some push understeer a little at first improved things a little but not perfect:

1. We added two turn of neg camber (one turn at a time) one turn transformed the turn in two went a little too far and I felt no gain.  We are going to back that off by a turn for the next test
2.  Next time out we are going to soften the front anti-roll bar to see if that helps
3.  Could also be a worn/overheating viscous diff module, that is being rebuild this week to a 4.4 and the silicone will be repacked if needed.

Turns out a 4.7 on the little 13" wheels was going to be too much 4.4 is going to give me 145mph top end and a 1st gear that will only be used in the paddock.  For the 4.7 to work I would have to have a far more focused gearbox super long first and very close ratios.  Something to think about when we go sequential.

Diff should be back next thursday which gives me 8hrs to fit it before Abingdon...  Easy.

Post by: boosted on February 19, 2016, 04:09:35 PM
Great to hear...strange on your understeer....mine never has any its oversteer that gets me . Whats it like when you got some heat it them fronts?
Title: Re: The other rotary Westfield!
Post by: Smiffers on February 19, 2016, 04:15:33 PM
Even up to temp the tendency remains...

Do you run a front anti-roll bar?  Here is my hunch...  The 13B is short, I have it a long way back in the car, I may just be over controlling the front roll couple and not allowing the neg camber to work well.  One thing I might try is disconnecting the front bar and see what happens.  Also when I order up the slicks for the season I'm going to go a little wider on the front tires to try and increase the baseline balance F/R.  so will be 24/57 Rear 22/54 front or Avon equiv.

Or it could be a worn diff, but that is down in Chipping Sodbury being taken care of, so we will see.

Things is ours are quite different...mine being live axled and a narrow and front and rear on 200 section tyres...plus my engine is good 100mm further forward than yours. Im really happy with handling on track its the road that scares me...goes skittishes on bumpy roads.
plenty of rubber on these a005 about 18months old now but happy for you to try them out at Abindgon.

Yeah, it is interesting.  Mine is the same on-road, takes all you have to stay out if the scenery!

I'm running 24/57 (240) Rains or 235/45 Radial V70's Rear and 20/54 (200) Rains or 215/45 Radial V70's Front.

Would be great to give the Yoko's a go to see what changes at Abingdon...  Would be good to do that before I order sizes for the season, thanks for the kind offer.

Keep me posted on your plans for Abingdon, as always still food and lodging available for you....  Might be putting a diff in on Thursday night mind you!

Its prob 50/50. Also i had loads of camber on the front i ended up taking it right off as tended to lift front of car whilst turning if that makes sense...i also settled on dead parallel no toe in or out.
Happy now aint gonna mess with it again.
Title: Re: The other rotary Westfield!
Post by: Smiffers on February 19, 2016, 07:40:31 PM
Yes I understand, if you have too much in corner grip from high camber and roll you end up lifting the inside wheel giving a twisting effect so back it off to get a good compromise.  I have not got to that point yet, car feels fairly flat and just scrubbing on under power, I think that is going to be roll bar related the more I think on it...  It's set someplace in the middle of the range at the moment, will try softening it up.

Toe wise I have 0.5mm in on the front and 1.25mm in on the back, stability feels great on track.  Might back off the rear toe a smudge to see how close to parallel I can get without it getting scary!
Title: Re: The other rotary Westfield!
Post by: boosted on February 19, 2016, 07:55:12 PM
Nice to able todo on an airfield circuit with plenty of run off! I did all my changes at Hullavington but only the front as nothing i can do on rear! I got the playskools anti roll bar kit happy with it very well made and fitted a treat.

1.25mm in on the back, stability feels great on track.  Might back off the rear toe a smudge to see how close to parallel I can get without it getting scary!

I would leave rear toe at that, run parallel on the front but anything getting near or anything inducing toe out on the back will get real unstable, but then I'm guessing you know that ;)

Post by: clive on February 19, 2016, 10:53:54 PM
Just had a look at your pictures, I love pictures and video for telling what is going on as many times this can show more than you think you feel.

Front end looks very good, but if you look at the rear camber and the effect its having on the tyre, to me  it needs 1.5 degrees of negative camber at the back (no more than that)  as your showing positive camber under load.

Then stiffen the back shocks up just a couple of clicks, or tighten up the rear bar slightly if you have one.

If I am right you will find turn in will be better and traction off the corner should improve, without hurting the front end, let me know  ;)

Day went well, kind of...

Started badly, night before after diff fitting went super smooth...  car wouldn't start, fractured terminal on a cell in the battery pack, managed to lash it back together and get the cells balanced before bed at 0230!

Up at 0700 to get the car and tools loaded and off to Abingdon arrive at 0900 pull the car of the trailer and the battery has not survived the night!  So the boys trundle off to Raceparts in Walingford and come back with a little gel cell an hour later.  Put that in and it starts on the button...  Success!  Kind of...

Go for a noise test 105db! Whoops, seems I have melted all the wadding in the silencer (again) during the 2 test days.  Agree with Erling that I can set a rev limit for the day in the ecu.  Rev limit set to 6750rpm away we go!

By now it is 12 and I need to put 150 gentle(ish) miles on this diff, 60 litres of fuel later and the car has not missed a beat, new diff run in, job done.

Probably not given everything seems to be working ok now, just finishing blue book prep for the first race.

Slicks arrived from BMTR, they have been awesome in offering advice, Got some Avon hill climb rubber to stick on next week.

More exciting news is a barn find in my grandfather in laws lockup in the US...  A Mazda repu (the rotary pickup truck), seriously thinking about crating it over here, not sure I have seen one in the UK.  Going to go check it out in the summer to see if it is viable.

Another successful day at the races - Goodwood circuit sprint.

What a place to race, it is balls out the whole way around and they have very nice banking complete with daffodils, I counted 1435 on the way round.  It almost makes the banks inviting!

Found out that 6th gear is still useless as we seem to hit a bit of brick wall around 135mph...  More power or less drag needed!

Any way my efforts were good enough for class win and 15th overall.

Few phone snaps, will get some vids up soon.

It's not so bad and Goodwood is one of the faster tracks around, with no run off, so I think that makes it look faster and more terrifying than it is. 

Just run out of power, another gear in the box.  The seven type cars have the aerodynamics of a brick (actually it is worse than a brick, but I wont get into that) so you need an awful lot of power to push them over 130mph just due to the drag.

Borg Warner 7670 for next season should deal with that little problem...  Now 150 mph might be knocking on the door of slightly concerning!

Post by: Smiffers on April 25, 2016, 06:15:20 PM
It all depends where you start and end...  The problem is (assuming nothing else changed) as the air speed increases so does the drag exponentially, the faster speed you got to, to start with, the more power you need to go even faster.

A generalised drag equation look something like this:

Drag = Cd x (d x V^2)/2 x A

Cd is the co-efficient of drag that is a constant the represents the slippiness or otherwise of the object it does change unless you change the aero
d is the air density (That does not change by much)
V is the velocity and is squared
A is the area of the body referenced (also constant)

So that pesky speed has an awful lot to answer for and gets exponentially worse the fast you go... booo!

Yeh, ends up like your driving through treacle. That's why the Veyron needed another 200hp to go 10mph faster I think

Yep and the Veyron had significantly better Cd than me!  I would not be surprised if I added 200hp that I only got 10mph as well (and I'm starting at a far lower speed) given the rubbish aero the car has.

Yes, I did have a westfield aero kit but got rid of it due to it being too ugly to put up with!  It's interesting that yours gets figety over 120, I was at 135 and apart from my head being ripped of my shoulders the car was as planted as it is at 20mph (this might be a slight exaggeration).  Do you run a chin spoiler on the nose? and a rear diffuser?
Title: Re: The other rotary Westfield!
Post by: boosted on April 26, 2016, 09:17:18 PM
I have neither....i did have a rear diffuser...but it got ripped off at about 100mph coming back from Hayward Rotary. Think the air pressurised it through the trans tunnel....

Post by: Smiffers on April 26, 2016, 09:37:59 PM
Ahh yeah, really there are three things you need to run a rear diffuser without that happening, the chin spoiler to stop too much air getting under the front and into the engine bay, some vented side panels to reduce the amount of air that go down the tunnel and some holes in the rear above the diffuser to reduce the pressure that does make it...  I'm not allowed the holes in the rear as per blue book for the class but so far so good!

Most events are around £100 entry (apart from Goodwood!!) but get down to £80 for some airfield events.  You already have everything you need so apart from fuel to get you there and back it can be a cheap day out.

Next up for me is Debden on the 8th, I think the entry is only £80 and I can put you up the night before about an hour away (Parents house) for a nice start to the morning.

Let me know if you are interested, I think the Westie deserves an outing hey?

Its awful on road due to roads round here potholed awfully that i worry that im gonna hit a bump and end up in a hedge...but on track its pretty good...combe has been semi resurfaced and felt pretty good but inits current guise i dont think i can drive it any faster...with irs comes the ability to add some camber to get the slicks working and some better rear end handling.

30hrs is more than you think when racing, so it is not as bad as it seems when you look at it as a day and half.

Sprinting for a season is probably only 15hrs run time...  Two seasons from a race engine would do me OK, its probably what I will get from my engines before I will tear them down to check all is ok and refresh.

It is an expensive hobby racing, if you are making money you would be at least partially tearing down the engine after every one or two weekends,  gotta make sure everything is still in spec to maximize those 10ths!

Another good weekend this weekend.  Car was faultless again, so far the rotary has been the most reliable car in the paddock so far! (I'm sure that will change!).  2nd in class to a very impressive caterham with a 'proper' gearbox and lots of power...  He had a second on me by the first marker boards (see video)!

Couple of little things to fix, oil breather needs orientation changing, it is on the side of the catch can and tends to drip down the side of the car and then out sprays a mist of oil on the back wheel!  No actual oil in the catch can so I can only assume it is just breathing as it is supposed to but not draining back into the can correctly.  No big bother just a pain to mop up!

I'm going to swap a lightweight flywheel on to the 'test engine' in the car, as the £300 ebay special has become the 'race engine' all on it's own merits!

Here was my fastest run of the day 93.20, FTD was a single seater with an 88 dead:

https://www.youtube.com/watch?v=h8bOvYldpLg (https://www.youtube.com/watch?v=h8bOvYldpLg)

1st timed run, 4 cones dead :)

Slicks are a sprint compound, Avon A15 (I think), not the super super sticky hill climb compound but only one grade off.  Pretty good grip from cold, they seem to work really well.

Another great outing at the weekend - 1st in class and 8th overall out of 190 cars. There is a chance that we had the course record for the class on both course layouts, but don't quote me on that until I have had that confirmed.  I'm getting much quicker now I get comfortable with the car and the setup is improved.  Will put some vids up later but here are some little bits and bobs from the weekend.

With your result, and the fact that Peter Hewson it leading his Time Attack Club Class with his RX-8, plus Liam is doing well in the 750MC race series in his RX-8, things are beginning to look up for rotary power in UK competition. Hopefully e a good omen for Clive this year  :) :)

Are they running turbo rx8s or NA?

That launch control is great, can't beat a good bit of second gear tyre smoke, especially on slicks. Probably helped to protect any parts that could injure themselves from the tyre hooking properly.

They are both running NA, with weight stripping and suspension mods. Having seen Liam's video, he's clearly a very capable race driver. I haven't seen Peter drive, but he's used a solid engineering background and a lot of maths to tune the "ride frequencies" of his car.....it seesm to be working!

Hello chaps,

Forgot to post an update from the last outing, back to Goodwood and had a great day out (apart from the fact I forgot my race suit and two of my friends had to do a 3hrs trip to fetch it).  The car was great, we improved on our last visit lapped time by 5 seconds (I thought I was quick last time), won the class and beat some of the bike engined single seaters to come 6th overall, not bad for a brick.  But to put it into context I managed a 89.22 and the fastest car of the day (A carbon Dallara) managed a 75 second lap!

Anyway here is the best lap... sorry about the condensation, have got some silica pads to go in to stop that.  Sure you can get the idea...

Great outing this weekend, probably the last one of the season for me as it look like Combe is over subscribed so may not get an entry.

Best result so far this year, first in class and second overall.  Missed out to a big power EVO that the course suited well.  Here are my timed runs, small mistakes on all of them, ironically my fastest one had the biggest mistake! Really happy with the consistency though 50.44, 50.37, 50.40

How did you get on at Combe?
Title: Re: The other rotary Westfield!
Post by: Smiffers on November 08, 2016, 02:47:19 PM
Really good, 4th overall behind some exotic high power stuff!  Came away with some class silverware.

Car performed well, track took a little bit of learning but got it all together for my last timed run above.  Need some more top end poke for Combe as it is so quick, final lap time was 78 seconds and some change from a standing start, not too shabby.

Thanks Casey...

One more little gem from this week, hand formed collector, using nothing more than a hammer, some hardwood knocking blocks, vice and a abrasive chop saw.  Welded it with argon back purge, don't want any lumps of oxide heading into the turbo!

Slowed down a little as I cut my finger off with a chop saw...  don't ask...  have been patched back up though and have started making progress again.  A long way behind with everything but hope to have first start in about a month.

Got a bump to come and update you guys,  turbo conversion is finished and we are out racing again.  I have taken on the timing and mapping duties my self and currently tuned to 9psi...  not sure I’m going to need too much more, enjoy the fun from the weekend.   First FTD and also the overall course record:)
