Mine was never driven in rain, maybe they are prepped differently than in 2004.

I thought you didnt like the resonance in the 2-3k range?

I'll bet a nickle there's another exhaust system on this car within a year.

I wouldn't take that bet..

I didn't. But for a virtual race car, it wasn't a bad thing.

I've been running the Flowmaster for years. Street and track. You can always cap one side for quiet drives.

Jack, I thought you had problems with noise at one track??

John,
The car is still in NC but so am I. Short visit with the boys at Zuffenhaus.

A few more from underneath.

I have only one tiny reservation about this truly stunning project and it is very UK specific - yet relevant for intended use in the UK.

It centres on the exhaust and the noise limits which we are cursed with in the UK for track days. Even "noisy days" have a 105db static noise test tested 1 metre from the tail pipe at a 45 degree angle and at 3/4 max revs. Most folks fudge it and test at no more than 4500rpm but some tracks look at your rev counter and do the math based on where the redline is. By way of example, my Supercup cammed 3.2 with 993HEs and M&K muffler tests 103db if I fudge it at just over 4000rpm and probably 105db at 4500rpm when its capped and in 2-in 1-out mode. I have tested it at 110db in proper 2-out mode - its a rallye style with 1 side and 2 straight back pipes. I can't see how this car will be under 105db as ITBs are noisier than common plenum intakes and stainless headers seem to be noiser as well for some weird reason.

Do not despair. We have solutions in the UK and some know-how in how to fudge the tests and indeed some tracks that have no testing at all - but currently, your track day fun will be limited.

Can't wait to see the car.

Not sure yet where we will end up next year, but Snett, Dijon, Spa, Le Mans and Magny Cours are on my list of wants, so as long as it comes in at *around* the 105 mark, this car would probably get on regular days at all of those.

After that it is just looking for the no-limits days like Silverstone GP and so on. If Teo elects to run with RMA or similar, they might have a degree of 'enhanced flexibility' in some places. Dunno how it will fare at Goodwood, Brands and Combe, though I have no burning desire to go to any of those - Euro road/track trips are where its at...

I know a few early cars with 2.8 motors on ITBs w/Motec and similar crossover exhausts on SSIs, they get on OK so we'll see how this one does.

Bob - thanks for the great pics, like the welding on the rear of those Lindseys.

Well Mr G, we both have much the same info to draw conclusions from, but I think 105db will be tough unless extra bolt on silencers are used. IMHO, we were lucky with the last Snet testing - especially Rainer. I have not seen that kind of leniency before.

I hope Matteo can join your/our posse and play wherever he wants. I am sure any problem can be solved, but as they say, be prepared :)

Yes I agree RB, will prob have to cap something but should get on without a muffler change is what I meant to say. Remenber that Ferrari Challenge Car at Snett, dunno how that got on but still it swung it somehow.

Considering the slick fit elsewhere on the car I'm a bit surprised that the exhaust tips aren't set up into the valance little bit - any reason for this Keith or did you guys prefer the smooth valance/low pipes look? Or is it the stock fit on the Flowmaster?

We were actually assuming that we'd need to fit the valance and develop the exhaust solution - but what you see is how the motor arrived - it physicall fits (very well) as is...

although, this could be replicated pretty easily:

what do you think, Matteo?

Oh yeah, that's what I'm talking about. Screw caps or Supertrapp fittings on that and you are really in business.

I much prefer the through valence exhaust, though it is still a stellar piece of workmanship.
Great work, guys!

Look forward to seeing the dyno data.

Good luck with your move Teo!

Socialism at its best...

What rear bumper is that? I need a new one without acordions.

Nice work by the way.

just wanted to make sure you finished tightening the right banana arm thru bolt / nut...

That was backfiring because of a hole I'd torn in the muffler. The Flowmaster by itself makes sound at Laguna Seca.

trying not to hijack this thread,
Jack O.: That was backfiring because of a hole I'd torn in the muffler. The Flowmaster by itself makes sound at Laguna Seca.
Do you know how many DB it makes?

...Those suspension pieces are dazzling.

WOW !


Just think though - if all the tuning with the laptop could s
be shared here what a great lesson for those of us without these skills.

Step by step stuff mastering Motec - with all the little things involved.

Yowee !! Keep this thread goin' full bore !

Hey Keith, where did you find those pictures of the red Foyt IROC car? I took those at RRII. You'll be hearing from my lawyer soon - copyright infringement and all...;). I hope that you guys are still up to no good and giving Bob a hard time. See you at RRIII?

I am officially in the UK....

I like the original IROC look better.

Having said that you know where my priorities lie... Inspection has to take precedence on anything else. Then let's move the tips up....

As per the noise restrictions in the UK... We'll see... I am sure we'll find a solution, be it a different muffler, fudging with testing or else...

PS
Keith did you find out about setting the limiter on the Motec at 8,000rpm?

I think its NIMBY-ism or political correctness gone mad. Not sure how you get to socialism though.

Sorry to go OT.

Welcome Teo! Here's another set of IROC pipes to mark your arrival, call it a fanfare ;)

Magnificent Keith, loving the oil system and the relocated tank.

looks like a show car, I can't wait to pictures of it used and dirty!

Very cool stuff Keith, i have a question though.

With the thermostat mounted on it's side like that in the center tunnel, won't the path of least resistance always be to the oil cooler instead of back to the tank?

I have the same unit and i have always understood that when mounted vertically, oil can flow towards the tank when cold, but really doesn't have the pressure to push it until the oil heats the internal spring and shuts off the flow through the middle and back to the tank.

I really didn't understand how it functioned until it failed last summer and oil temps were up drastically. The line to the tank was hot but the return line wasn't because it didn't have the pressure to get to the front mount cooler.

Thanks,
Paul

I'd rather ride straight to Hell in Satan's 917K. At least I can be sure we're not going to putt-putt along at 55mph!

what kind of oil cooler did you put in? Any drawings or specs on the mounting brackets?

Thanks!

Looks like a 72 row mocal cooler with custom mounts.

I question my own car's ability to cool ('95 3.6 w/ Super Sport Cams) with the 72 row Mocal cooler. I guess the cooling requirements may be different now in the UK?

Not to sidetrack, but I'm planning to an in fender Carrera cooler in series, because I've seen temps creep up above 210 under non track conditions.

Keith, is this a possible issue? Like Teo's car, I have good airflow through the cooler from an enlargened nose valence.

How long is the oil cooler? Just for reference sake.

subscribed

*IF* it is a Setrab 172, which it appears to be form the pic, then the core is 22.50 inches in length. It would be 2.0 inches thick and 6.25 inches tall. I use that cooler and it is a good fit behind a bumper with a cooler cut out....


Cheers

Keith - if it's not a headache - perhaps you'll consider showing us some of the tuning and 'whatnot' taking place with that motor. (?)

This is the most interesting stage of the whole project.......
Once it's on the road, the fundamentals of the motor, mapping, timing etc. diminish to some degree. But hey, you got your hands full with it.....and most likely have things to work on besides entertaining pelicanites.

Excellent updates thus far...

Basically...., we're all curious about the powerplant.

Jeff,
Do you have cooling issues? Or do you run a second cooler, also?

Doug

Lol, that's the "stuffed up there so we can figure the line length" shot. - I guess I should choose photographs more carfeully...

The Tstat is actually mounted on the wall to the right in real life.

I'll post more pictures as we get it together.

BTW, did I mention that we are driving it around the shop at this point?

DW SD - we've left room for supplemental Carrera-styled coolers in the fenderwells if they prove to be necessary, but we're thinking they might not be - we'll see how well the side exit (with supplemental fan) setup works soon enough!

How's it run?

Doug
