[Hostile_1LE]

I am thinking of bumping my compression up in December when I have my motor out. Currently I am running too little compression (11.5:1) for my cam. I still want to be able to run pump 93 octane without having to us octane booster, but I want to give my cam some more comp to play with.

What is the max compression I can run and still be able to put 93 in the car and have it be happy.

Currently I am HCI with:

SS3
GPI Ported Heads
MSD
103mm
Roto-Fab
1 7/8" catless LT's
E85
Full 3" straight pipe
GPI Tuned
Car weighs nearly 3900 lbs with me in it.

My guess is 530whp based on the runs with others cars that I've gotten.
