| There is a reason forced induction cars typically have lower compression ratios. You will find plenty of examples of cars Zs included that have/are running higher c/r and forced induction and making good power. You run higher risk of catastrophic failure with a boosted high compression car. I look at it like this if you have higher compression you have less room to stuff air into via turbo or whatever and thus cannot take advantage of power gained by raising the boost levels.This means less air getting pumped out per stroke and turbos not being used to there potential. The very definition of compression ratio makes this clear. The ratio measured is it largest capacity down to its smallest. That's why most people say 8 to 1 or 9 to 1, largest to smallest. Turbos and super chargers are made efficient by the ability to cram air into the cylinders. If you have a piston with higher compression you have less room for that air.
