If there's anything that the Shelby GT500 lacks, it's definitely not power. At an MSRP of just over $40k, it has more horsepower per dollar than just about any car out there. The boys over at Ford Racing and Roush, however, thought that it could use a little bit more. The two have developed a supercharger upgrade for the GT500 that pushes horsepower to just over 600 while keeping a 1 year/12,000 mile drivetrain warranty. This will most likely be the supercharger used for the GT500 KR as well as the base supercharger for the Shelby Super Snake. Pricing is set at $5,600 and the blower can be purchased through Roush or a Ford Racing distributor.
