[QUOTE="Stanger00, post: 12463481, member: 128629"] I wouldn't go with 9.5 comp. You aren't really gaining much power for the risk of detonation with crap fuel. I haven't done the math but I'm running a aluminator with 8.5:1 compression if I were to bolt on 4 valve c heads. I'm running 44cc TFS heads and with the smaller chamber my compression is up higher but still below 9:1 compression. However I am running 16 psi at 7k rpms and with 19* of timing and 91 octane the car pulled just over 600hp. My tuner dialed back the timing for daily use and even with that tune the car is more than an animal. I would turn down the 9.5:1 compression just for piece of mind. Edit: with 15 psi at 6500-6800 you should be in the ball park of 550-570. The cams and intake will start to cork up around 6200ish. I'm running a bigger cam and my stock PI manifold didn't start to restrict till 6500 and was making power till 7k. [/QUOTE]
