[QUOTE="Fourcam330, post: 3394179, member: 24445"] John Mihovetz makes 2000HP @ 40psi with a .020" over 4.6 (twin 72s). A 5.4 can in theory make more power though no one has to date. I asked John a few mos. ago if he thought about switching to a GT block 5.4 in his NMRA open comp. cougar (6.7s@210+ with 4.6). He replied that he's thought about it, but there's really no reason to switch since he doesn't feel he's tapped the 4.6 yet. John's made over 1500HP with Reggie Burnette's procharged 5.4s which is as high as they've gone so far--blower limited. Regarding forced induction, the real power limitations on a motor built as such are the power adder(s) themselves--as in, how much air the turbos or blower can flow. On the whole, the motors are more of an afterthought. If you're talking N/A, the highest HP 5.4 makes ~570rw vs. ~440-450rw for a 4.6. [/QUOTE]
