If theres no money limit then theres no power limit or atleast thats my view on things. u can always have more boost better flowing heads etc. just depends on how much money your really talkinh about spending

Fourcam330, Some Vipers have in excess of 1,200 hp. What hp do you think the GT's 5.4 can be built to (regardless of cost)? Thanks.

www.svspower.com is making 1725 rwhp from the vipers engine.

accufab has pushed the 4.6 ford V-8 to 1800 crank hp. so it stands to reason that they can get 1725 rwhp out of the 5.4.

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.

VT Engines is doing some big things with 5.4's, as well as a few others.
