Very nice, Chris. Congrats. Your cars are running very strong.

 

Scott,

Thanks.

I heard your Porsche is an ANIMAL! Your car gives us something to shoot for.

We only have 2 boost target settings. One is used for 91 octane pump, and the other is used for pump+meth, race and race+meth. This unfortunately makes our pump+meth boost level the same as the race fuel level which only allowed us to run 23psi for high boost.

With stage 4 we're going to cut that back to 3 settings so we can target a much higher boost level. It will be pump, race and race+meth. We just need to run a slightly larger turbo and a different clutch and I think we can squeeze 1,000rwhp out of it.

I should have some Stg4 results in another month or so. Talk to you soon.

Chris.

 

23 psi is my max boost level as well. I don't run meth, though. Just race fuel.

Looking forward to seeing your Stage 4 results.

 

Yea, I think we're going to need stage 4 to keep up with you.

 

My goodness, I seriously want another M with this kit hmmm

 

how does the rest of the driveline hold up? This is exceptionally impressive

 

Thanks. The entire drivetrain has held up without incident so far. The factory drivetrain is pretty stout, but I also believe one of the main reasons is that we're still retaining the factory dual mass flywheel, and we're running a slippable single disk clutch. This provides a nice cushion every time the car is shifted. We also have yet to someone take these beasts to the track with some monster slicks and do a major launch. At that point we'll know if there are any drivetrain components we need to create.

Chris.

 

Did you make 889rwhp at only 23psi, or was that done at higher boost? In the Supra's we're lucky to make 700rwhp at 23psi so I was surprised to make around 819rwhp at 23psi in the M3. To make 889rwhp at 23psi in the M3 would require a larger turbo than the 74GTS we're running.

If you wouldn't mind me asking, what engine displacement and turbo are you running?

Chris.
