fuel choice, cam, combustion chamber, piston design all play into this so there is no simple answer, only pay yur money and takes yur chances
here is my 02
first decide on the fuel and cam,
I like 10-1 on pump gas, and 11-1 or so on e85 for a street machine
compression ratios on race gas can be similar to e85
I ran 9.5 to 1 on my twin turbo ttix car which allowed me to make 600 to the wheels on pump gas and 800 on meth
it's an ez combination that's held up well

Which ever allows the ignition timing for best power/torque for your package and desired boost, fuel, charge temps etc etc without being knock limited.
