Hi guys.

I don't own an Evo, but have a Fiat Coupe 2.0 20V turbo.

I need some thoughts as I know a lot of people on the forum have experience with the turbo I run.

My setup is the following(the important bits).

PTE6262 DBB with .82AR turbine housing
PTE 46mm external wastegate
Full 3.5" exhaust from turbo
Fully forged motor

I made 502WHP when my car was mapped, running 2bar or approx 30psi at 7850rpm. My car revs to 8250rpm, but I had maxxed the dyno out as it was limited to 145mph, and my car does 160mph in 4th gear, which is what the run was done in.

Here is my question. Does 502WHP at 2bar seem like an accurate power figure on a 6262? I see guys on here running 600WHP and over with the same sort of setup.

I've had doubts about whether the mapper extracted everything out of the setup, although it is running very safe. If I take my car up against a car with the same setup but with a GTX3071R, I am only just pulling away from him, which doesn't seem right to me!

 

What fuel are you running? This makes a big difference. Also you say the dyno pull for your tune was done in forth gear? Does this car has a six speed in it?

What kind of dyno was the car tuned on? Any idea what a stock car like your would put down on the dyno?

 

I'm running 97 octane pump gas. The car used to have a 6 speed box but I changed it for a stronger 5 speed. 4th gear is the correct gear to do the dyno runs with as it's the closest 1:1 ratio.

My car was dyno'd on a Dastek dyno, and they are known to be slightly optimistic!

Stock they run around 160WHP.

 

Seems reasonable on pump gas.. I made 650~whp on E85.
