With only long tube headers, an x-pipe, an axle back, a cold air intake, and a custom tune my car is putting down 452hp at the wheels and still knocking down 20+ mpg's. Once I put a blower on this car I will be at 600 rwhp easily, and for less than the price of a Shelby. Of course the one disadvantage to doing this is you can say bye-bye to the warranty (unless you get either the Ford, Roush, or Edellbrock supercharger which all seem to come with some kind of warranty protection) And speaking of the Roush; have you considered that as an option on the Mustang front?
