2002 mustang gt
with PC piston 17cc dishes for boost, some people says my compression ratios is 9.40:1 with the PI heads.
is that a good compression ration for daily drive?
how much psi i can boost with those pistons?
Its fine. The only thing it prohibits you from doing is running large amounts of boost or adding a lot of timing unless you run a superior fuel (e85 or meth injection)
