E46 Turbo Project Progress

[mkodama]

I just read through this entire thread and I have to say the combination of the great driver, the awesome car, and the incredible crew makes this such a fun thread to read. I mean, all the work that is done to this car and the speed that it is done is just unbelievable.

Oh yeah, and I came up to the Thunderhill race. I was working with Henry Schmidt and his E36 M3. This thread kinda answers some of the questions of why your car didn't qualify and why it came out of no where and took the lead. Also, I guess the 567 hp explains why you were so fast, our car has only 485

My only leftover question is why didn't either of the evosport cars race on sunday?

Thanks for the kind words. It has been a fun development project for 2007. Most of it has been fun anyways!

I race the car with about 450 whp for longevity reasons. The motor has actually put out 670 whp on the dyno at a pretty high boost number, but that was with a bigger turbo and a power band that was literally on/off. We have downsized the turbo and eased the boost so it is very driveable at 450whp.

The only problem is that it gets heat soaked after about 30 minutes. We were very fine for 30 miutes on controlling temps, but the last 8 minutes of the race we spiked water temps and twisted the block. We have twisted the block before, so this is not the first time. We just need some more cooling capacity to keep the engine temps in check.

Lagoni didn't race on Sunday because they lost a turbo in the Saturday race. Like I said - development year!

Looking forward to a racing year in 2008.

Is this the same car that you posted about in the other thread? An NA E36 M3 CSL?

Jon, what do you use for cooling now? What are the plans to improve it?

I use a C&R double pass radiator and a big oil cooler. But everyone thinks of that!

It's really all the little things that evosport has done/is doing that makes a big difference. Everything from controlling intake air temps so coatings to shielding to covering heat sources. Then also evosport has some proprietary knowledge in head cooling and exhaust port cooling that really should help contribute to reduced temps.

It's really 100 small things that make a difference.

Yep, 485 hp 3.2 liters. But I think the rev limiter is lowered to save on engine maintenance, so maybe not all of that is being used. Nonetheless, the guy who preps the car says it can run circles around GT3 cup cars.

If it is naturally aspirated, thats an AMAZINGLY healthy motor. I know it is a Euro S50B32, but I really didn't know they went that much HP. Is it punched to 3.4 liters?

I'm fairly certain that an E36 M3 CSL was never made.

It was - or at leas the concept was executed in the 1995 M3 Lightweight. They came stripped without radio or AC or sunroof. Although they did have power windows and locks.

The car in question though (while it may have been a LTW - I am not sure), is more appropriately described as Billy Auberlen championship winning car built by PTG. I don't remember the year. It was owned by Gil Caravantes out here in California, then sold to Henry Schmidt in Cali also. It's a beautiful car and an amazing example of workmanship.

[ParadigmGuy]

OK, cool. I'm glad to see that you know about the car in question. mkodama posted in another thread earlier in the day about an NA 485HP 3.2 liter, so I'm curious to know more about the car.

[Jim Bassett]

Dunno about the 485HP figure, but the car is "listed" as a 1998 when signed up for CR's. You can see the old 1998 PTG hero cards here (it's actually the first "1999" card - check the image link):

FWIW. That's just what I found by JFGI, no guaranty expressed or implied

Jim - watched that car race professionally, been on track with it in Club Races

My car runs 450 whp in race trim and I was able to move from last on the grid to first over a 35 minute race. As most of you all in the force induction forum have tought me, while I like whp number, I let my car speak on the racetrack by what it can do. Just think of my road course racing as 30 minutes straight of running the 1/4 mile with turns thrown in for fun!!

It is an absolutely beautiful car. It's one I still lust after.

Jon, saw the car at SEMA. Very interesting setup. I hope i get to see it in action some day.

[DessicatorGC]

Jon, have you thought about getting a glacier and strapping it on the hood?

really can't thank you enough for letting us learn so much from your projects

maybe you should run some east coast events to help with cooling. there should be no problems with a Feb VIR date, i bet snow would help the temps

He's in California, so the cost of the environmental impact study to meet the regulations of moving a glacier would probably be cost prohibitive. ;-)

Not only that, but the state of California has declared said Glacier a "cancer causing agent", added a use tax, requires and environmental use permit, makes me clean up any waste water generated by it's melting, makes me buy "offset credits" for the water that evaporates into the atmosphere and then 'recycles' the waste water to be used as drinking water which they sell at rates close to gasoline. But the sun shines 360 days a year, for which the Democrat State Congress takes credit.

I'm pretty sure it's still at 3.2 liters. But I can't be absolutely sure about everything since the guy who preps the car (also my neighbor) is quite secretive about everything. Often he likes to give people false info about the car. But that's racing sometimes...

But all the little details that go in the car are so fun to look at. Like the braces on the shock towers, are made of of three different diameters of pipe and beautifully welded. And the gigantic carbon fiber intake that can honestly fit a small dog inside it. Also the on-the-fly driver adjustable sway bars were something I've never seen before.

Than again, a 2.1 liter turbo capable of 450+ hp that can pass our car and continue to pull away is an even more amazing feat.

Yeah, I know John and his reputation for mis-information (whether as part of strategy or not). I would venture a guess that he has inflated the HP number just a bit but no matter.

The cockpit adjustable sway bars and the sequential trans in that car put it in Super Mod (where it is appropriately classed) and are both very well executed. Again - me likey.

[TomM]

I doubt the motor is making 480. The strongest motor PTG built was a 3.4 S54 at around 480 +/- 3 or 4 hp. I'm not saying it's not possible, but on a club racers motor that undoubtedly doesn't go 30hrs before rebuilds, it's not likely.

Plus, that engine power quote would defy the laws of internal combustion physics in terms of its max theoretical HP.

Does it have a sequential or a straight cut box? How is the maintenance?

Once again, John who is in charge of prepping the car isn't always honest with everything. But I'm pretty sure it has a straight cut gearbox. Please excuse my lack of car knowledge. As in, the car has the typical H-pattern gear selector and a clutch, but the clutch isn't ever used for shifting. Makes for some pretty loud but quick shifts.


PS: Strangely enough, most of my car knowledge is Gran Turismo 4 and the internet. I feel like such a poser. Sorry for any incorrect info.

[Steve J.]

Is there a shop thats running the car, or is it privately/personally run?

What John is this?
