Under rpm, you can see the clutch slip.
I can get some pictures next time the owner comes by.
He is getting a new clutch, so we will retune with the new clutch. He also has exhaust leaks, and we tuned for 10.8 afr, but it felt like 10.0.
So with the new exhaust gaskets, a bit less split, and a bit leaner afr, we are hoping for 470whp at 1bar boost

Stock FPR?
Are you running higher fuel rail pressures than stock?

550/1600c is ok, but I am pretty sure they are borderline.

But believe me, the car is INSANELY FAST! I have tuned many high horsepower cars ( 800-1000HP), and this rx7 can really hang with some of them. I guess the weight of 2000lbs helps to run with a 800hp Supra ( 3600+lbs).

even though that turbo is mixed parts. I was going to get a T72 instead of a T78. if i knew now what i known then I would of gone with a T72.
BTW how much power you think that 550/1600CC's can hold cause i have close to the same setup?
