so early, I wonder how much diff comp ratio could make. It's clear how higher c/r makes power in an NA engine, but it seems it would limit power in a TT engine. Isn't it true that a boosted engine will create enough volumetric efficiency that the limiting factor in power is the size of the combustion chamber when the piston is at tdc? I could see some argument for higher c/r if the setup has a lot of lag, but even then, one would trade a little low-end response for a large loss of power at the top end. I don't speak as an expert here, but I'm curios as to whether I'm right in my thinking.
