I suppose, although the Ford Racing / Whipple high-output intercooled supercharger kit for the 4.6L 3V is rated at 550 horsepower using the supplied Ford Racing tune. Only time will tell, really, as to what the new 5.0L will be able to withstand. Whipple has a leg up on the competition, IMO, in that Ford's engineers are the ones creating the tune(s).

Is that 550 to the wheels or total output?

KB superchargers are usually louder than Whipples. I'd bet because of the sound deadening on the 2010+ you just don't hear it inside the car; I hope it's louder outside!

Without changing the 11.0:1 compression ratio, I really do not see the same enormous power increases being available to the new 5.0 as we see with a simple supercharger and tune on the 9.6:1 compression ratio 3-valve SOHC 4.6's...

As Kenne Bell's data already shows, the 3-valve SOHC heads give up nothing compared to the v4-valve DOHC 03-04 Cobra or 07-09 GT500 heads in a forced induction application...

Yeah im sure thats the cause, also KB didnt bother incorporating that inlet tube that supposed to bring more noise into the cabin.

Awesome, this is something to dream about if I ever get bored with my stock 2010.

This was sort of touched on by cdynaco's question -- was there any work required to the bottom end for the boosted output; or was it basically bolt-on top-end only?

Everything I've read to date says the 5.0 has a forged crank. Unless I'm missing something?

This is an excellent read regarding the new 5.0L engine.

From the article:

*Crankshaft: Forged steel, fully counterweighted, induction hardened

*Coyote Mustang cranks are beautiful, fully counterweighted forgings. Ford says full counterweighting was necessary almost the minute it upped the rpm and load from Three-Valve 4.6. Both main and rod journal dimensions are carryover from the 4.6; wider journals were not needed and would have increased drag. The dark-blue tint is from induction hardening

No work needed... which ws surprising, we were thinking the car would make around 430rwhp when it was all said and done, but i'll take the 482rwhp

You're right, I drove into a tunnel the other day and gunned it... the whine is present!
