Crazycage certainly has a spot on cylinder head (and inlet) to make 260 HP at only 16 psi boost.
You will find out soon enough how good your head and inlet are. Hopefully you will not require 25 psi to make 250 HP.
Cheers
Thanks mate, lets hope so.
mike tanski from ferriday eng ported my head , and that was a flywheel fig ..it was 233@ the wheels.
just found an other graph for it from before it went to jamsport fot the management and cam ,made 160hp@ 6psi on the standard ofab and standard injectors with my inlet but standard exhaust manifold.
160 at 6psi still isn't bad going! think mine was 110 @ 5psi on mfi etc.
edit just looked, it was 105 @5psi lol
