Can S4 V8 use RS4 parts to get 8250 RPM?
When I look at the port vs. FSI versions of Audi's V8's, the 7200 rpm version only went from 340 to 350 hp. Since the RS4 makes 420 hp, I am thinking a FSI-less version would make ~400 hp. Given the problems with FSI and RS4's in general, I am curious if anyone has looked at using some RS4 V8 parts to make a port-injected V8 with 8250 redline.
The RS4's V8 has 32 valves vs. the S4's 40 valves, but I am guessing the switch was made to accommodate FSI rather than to raise the redline.
I would think the higher redline would mostly require stronger rods, lightweight pistons, stiffer valve springs, and hotter cams.
Does anyone know the major mechanical differences between the two V8's?
