That's a good point, I haven't driven anything with a centrifugal supercharger. It may be a different experience, though from my reading I think it is quite similar. Superchargers are known for instant response because there isn't the need for exhaust flow to build boost.

There's also the question of integration of an aftermarket supercharger. I had a BMW 318ti that was supercharged and a huge PITA, very temperamental. All of my Mustangs have been factory supercharged with an OEM level of integration.

(edit) I'm curious about the why here though. Cost wise, it makes more sense to buy a 5.0 since a street driven blown 4.6 with stock internals is roughly the same horsepower as a normally aspirated 5.0...

But if you want to go really crazy..

BTW, 4.6 'Stangs are 3 valves per cylinder. The 5.0 "coyote" engines are 4V.

I suspect because you can get a 4.6L Mustang and supercharge it for less money than buying a 5.0. Personally I also like that body style better (pre-2010 S197). I actually have two Stage 3 Roush Mustangs right now, both with the 4.6L. My 2008 427R is 435HP, my 2010 Stage 3 is 540HP. The 2010 has forged internals from Roush as part of the Stage 3 package, so it's a more comprehensive build than the 2008.
