ok im sure most of u all have a better understanding about the whole compression ratio thing works. Sorry for the dumb questions but i seriously dont know shit about this. I hear all this talk about how some people want to raise the compression and others want to lower their compression. It seems like for turbo cars people tend to lower the compresion, so does that mean if ur goin NA u should raise it?? i dont know im pretty confused it seems like theres a lot of contradiction goin on when i have been reading about it. im lost can some1 please fill me in and help me out here. What would be a good ideal ratio, most likely for an NA car, i would love turbo but honestly i dont have that much money left haha. Thanks everyone.
