Message	But it's not quite identical. A higher compression ratio is higher in all conditions...cold/hot, throttle closed/wide open, idle/redline. A turbo starts out with nada, and builds up, and then you have that whole intercooling thing. So why don't people do what? Run high compression? They do. The NA at 10.5 is getting up there (and was definitely high for a Japanese car when it came out), and people run small blocks at 11, 11.5, even 12:1. Usually cars that are turboed aftermarket either have their compression lowered, didn't have unusually high compression to begin with, or are running pretty low boost.
