ok i recently did a pi headswap
and i wanted to know how much compression that changes my car to.
also i wanted to put a kennebell on it. how much boost can i run? i heard it was about 6psi if i intercool it....would that be worth it?
eh i dont like the idea of a twin screw/roots on a stock rotating assembly. the stresses of instant boost at low rpm's on the stock RA just gives me the heeby jeebies.
if you have 97 pistons with PI heads you get too much compression you need to lower it with thicker gasket or work the chambers look for 9.1 CR and you can run safe 12 pounds of boost and with intercooler a little more
