Copy dat good buddy..
I've been staring the rear end of IRS test mules running around Detroit for nearly a year.
A Boss intake is good for 30 crank hp with the current heads. Ford warranties the 575hp TVS blower setup so they must trust the internals. If the 5.0 gets direct injection I can't imagine 475hp is that far of a reach.
Where are you getting 30 crank hp from just an intake manifold?
