how much compression?

how much compression can you run with a fi setup. im looking at 9.7:1 static and 8.0 dynamic. once you factor boost into this, it gets really high really quick. how high can i go? im looking at 14.98:1 on 8 psi. thanks -Dave

I'm at 8.7:1 and am limited to about 12psi on 91 if I don't spray some meth/water. With meth/water I've been doing about 15psi. I wish my motor was 7.8-8.0:1

With ATI ProCharger centrifical superchargers, we set the compression ratio in the 9.0 to 9.5/1 range. With a front mount intercooler with the above combination we can run 16 psi on 93 octane pump gas. Bob
