I am planing to install a Vortech supercharger S-trim high output on my 93z and I was wandering if anybody has insite as to what is a safe bore range if i run between 10-15 psi along with the best compression ratios. My exauhst would be Hooker lt super comps with a borla or corsa exhaust. Please feel free to correct and make suggestions to increase this combos effectivness.

 

When using a supercharger it is best to leave the bore as close to stock as possible, and if you want to run 15 PSI on the street on pump gas, keep the compression below 8 to 8.5:1. The exhaust, the bigger the better, when you run 15 PSI the engine effectively got twice as big. Watch your head gaskets with that kind of pressure
