I will share a little bit here.

My drive pressure ratio with my current turbos.

42 psi emap
23psi of boost from MAP sensor

42/(23+14.7) = 1.11 ratio

I am golden. 1.50 is the get nervous point where it shows I need larger turbos. You can go higher but it is not wise.

EGT's showed no restriction in the Fast Intentions exhaust manifolds.

The highest the IAT's got was 116deg. That is in a 95 deg shop and after 5 pulls on the dyno. It never got any higher. It's dead on the money. The front bumper was on the car.

I did 870whp at 23psi of boost. I can go higher but no need to share here.
