Supercharger Compression Question I am thinking of adding a entry level LOW BOOST supercharger to my 383
LT1...the engine is all forged and of course balanced..with all the mods. Ported lt4 heads, cam, long tubes, intake, fuel pump, roller rockers..etc
Currently making 440 rwhp, but of course we always want more. As I said I was considering adding an entry level low boost supercharger my only concern
is compression which is 11.8 to 1. I don't want to redue the engine..have to much cash in it so if the supercharger can't work with my setup I will just have to let the idea go...Any help or advice would be appreciated...Thanks MM

I think even 5-6psi is pushing it with that much compression. I would get new heads with larger chambers like will82 said. And you'll pick up a lot of power with those as well if you get a good flowing set.
