for all you guys running mid to low 10's/ high nines. how much boost out of what kind of turbo are yall running. i am shooting for some low low 10's. i have been playing around on desktop dyno just to kinda see what kind of power it is saying. it is showing @640hp and@830torque on 22psi. i know if you look at the precisionturbo chart/graph. 640hp doesnt put you in the low tens. but it doesnt take into effect all that torque. am i way off base here or what? i was hoping to get away with no more than 24psi out of a pt-70. i hate changing head gaskets. thanks guys. jeremy
