basicly what you have is a belt driven turbo and it has to spin up to make good boost. With a roots type you have all the power right off the start.
Roush make a roots type supercharger that bolts right on your engine. Ford uses it on the GT500 and also sells it for the F150

I spent quite a bit of time comparing different blowers, asking experts. Vortech went all out on their 06 package for the stang. it says it will add 160hp with the smaller pully. We are at/very close to 460 now with the bigger one and flowmaster headers, so I would say their calculation of 160hp gain is dead accurate. I don't think I can get the power out of a roots type like I can the Vortech. With big pulley we got 383 rwhp and 428lbs tq. Plus cost was a factor, by far the Vortech was the cheapest. $5000 included EVERYTHING, even the computer, fuel pump,injecters, Literally everything. The drive train on the stang is pretty good, only a 15% loss in HP. We left all the factory goodys in including the traction control so it still rides smooth as hell. I was gonna lower it , etc, but I don't think I will. I like the luxery ride too much.
