My car made 607rwhp through a th400 trans. That's with dual gt pumps and 60's at 20 psi. If I wanted to go e85 could I just go with 80's and turn the boost up to make 700 to the tire
I made 657 rwhp at only 16.6 psi and 19.5 degrees of timing on E85 and 80's with OE rails. If my memory serves me right, the injector duty cycle never exceeded 75-79%, and the pumps (GT's) 81%. IMO the larger injectors (105's) make smooth driveability an issue...kinda depends on what your car sees most...street or track.
