    Keep it under 7-8psi and you could probably go as high as 10.5:1 with premium fuel and conservative timing.

    You could probably get away with 11-12psi on pump gas with 9:1 compression.

    All that goes out the window when you start talking higher octane fuels, methanol injection, aftermarket cam profiles, etc.

    How about filling us in the rest of your engine specs before going any further? :shrug:
