Yeah, I mean if everyone had access to 100+ octane race gas all the time then no one would care about compression. But we don't and for alot of us 91 is the best we can get, so this "compression doesnt matter" talk is confusing me. They say just make sure its tuned real good. Well what is involved in this tuning? Retarding the timing a grip and run octane booster all the time? And if it didn't matter then why do all the cars that come with forced induction from the factory run somewhere in the 8.5:1 range if not less.
