You are right that making the same HP with lower compression means more boost. The only thing is that Direction Injection really changes those normal rules. We can run 25-28psi on 10.0 CR Mini engines all day, only because the direct injection allows for a near det free environment at those levels. Its not det free, but its very forgiving that is for sure!
