2006 Saleen Mustang S281 Supercharged front

The most famous and fanatic Mustang tuner takes a stab at Ford's new horse and ends up finding quite a few more. Starting from the 300 in the Mustang GT, Saleen ups it to 325 on his own, 400 with the aid of a supercharger, driving through either a 5-speed manual or automatic and riding on the Mustang's live rear axle. The bad news is that he charges $38,000 and $45,000, respectively, for these extra-strength Mustangs. The S281E and its "estimated 500 HP" serve as the final threat.
