I'd wait for the whipple or KB.

KB is going to have three. 2.8 Mammoth, 3.6 L, and 4.2. Muahahaha!

I love it when aftermarket companies advertise "crank" hp.

Unless they have an engine dyno, they are just speculating.
Just advertise the rwhp gains over stock on the same dyno.

S/C looks bada$$

I want to see engine dyno runs. I prefer to refer to bhp (engine HP) instead anyway...it's a larger number after all.

with the CR of that motor i cant imagine more than 5-8psi. you going to get some wicked cylinder pressures even at that boost level. but i guess with that high of a CR your going to make bigger power under boost anyway. the 5.0's are making what 370whp on average so say its a 6 psi(thats a giant pulley) kit its probably making in the range of 460whp or so? akin to a 3v on 9-10psi. i really doubt its making near 500whp or over 500whp. its just too far fetched with how the 5.0 is setup.

Again, my point of listing whp.
Speculating on crank hp without an actual engine dyno is pointless.
What's important anyway is how much of that power is getting to the ground.

It's simple, go to their dyno get a baseline to the wheels. Put s/c, tune and anything else on, go back to same dyno and redyno.
List whp and the delta gain.

Chances are this s/c is running 7 psi as that apparently is the recommended max with the 5.0's 11:1 CR
Whipple is stating with 7 psi you get "around" 600 hp.

You have a tough time marketing 510 rwhp on a car that starts with 415 advertised hp.. It is all about perception. People don't think of the 5.0 mustang as having 350 rwhp, they think of it as having 415. You have to put the numbers where people will recognize them.

It doesn't help that you can get 460-480 rwhp wth the "old technology" 4.6. The perception is that the 5.0 has 100 more hp than the 4.6, so any mods have to follow that perception by showing a 100hp difference for the same money. So if you can get 550 crank horsepower from the 4.6, you should be able to show that you can get 650 crank horsepower from the 5.0 at the least. In reality, the high compression ratio isn't going to allow for it on a stock 5.0 motor, and that compounds the problem.

People who like to mod cars need a reason to get the 5.0. So far, the best reason to get it is because it doesn't need any modding to be a great performer, and that excludes the mod market.

Don't expect anyone to be advertising rwhp differences with the 5.0 anytime soon.. at least until after the memory of near 100% gains in hp from a modded 4.6 are long gone.
