Wats the max performance i can expect to get using a 4x4 I/cooler i currentl have a std 2wd item but hear there is a boost drop/lack of boost response on RS500 sized units if not running decently high PSI levels.
I want about 340bhp 26psi max with lagless boost from std compression will a 4x4 or 2wd item still handle temps?

Will i notice the drop in boost using the bigger 500I/C. Is there something in between if so?
