The low compression (within the given range of pump gas), high boost set up is better. have you searched... its your friend. low compression with high boost allows more air/fuel into the system, and takes advantage of the compressor's ability to over fill the engine. Web14 de dez. de 2009 · If you have 9.5:1 comp with 12psi and make 600hp your cylinder temps are "Y". If you dropped the comp to say 8.5:1 at 12psi you might make 580hp an have 500rpm more lag but your cylinder temps are now "X". Since the temps are lower now you can increase boost to say 15psi before your cylinder temps are up to "Y" again.
