Ford's brand new Shelby GT500 Mustang is a masterpiece of automotive performance, packing a 760-horsepower wallop courtesy of a supercharged 5.2L 32-valve V8. Paired to the rear wheels exclusively through a 7-speed Tremec dual-clutch transmission, this "Predator" V8 engine propels the GT500 to 60 mph in a scant 3.3 seconds, and through the quarter-mile in just 10.7 , per the manufacturer.

That's marvelous and all, but what if you want to row your own gears the old-fashioned way, while maintaining that superfluous level of grunt? Enter the Ford Mustang Jack Roush Edition.

The latest Mustang-based ballistic missile from from Roush Performance , the Ford Mustang Jack Roush Edition actually surpasses the new Shelby GT500 for peak output, wringing up to 775 horsepower out of the Mustang GT's smaller 5.0L Coyote V8. That figure is made possible by a supercharger designed in-house, and it's supported by an up-sized radiator, plus auxiliary oil coolers for the engine, transmission, and differential. More power equals more heat, and more heat equals accelerated wear - unless you find a practical way to disperse it quickly.

The Jack Roush Edition's 5.0L is fed air through a custom air box, exhaling through the company's excellent H-pipe active exhaust system, with a knob to control the noise level placed right on the central tunnel. But best of all, Jack Roush Edition buyers get a choice between the Mustang GT's two factory transmissions: 10-speed torque converter automatic, or 6-speed manual.

We say "best of all," but really, one could make a case for the active carbon fiber wing being the Jack Roush Edition Ford Mustang's true pièce de résistance. That wing - along with a chin spoiler, fender vents, hood heat extractors, a rear diffuser, and some other exterior enhancements - elevates the Mustang's appearance to aggressive new heights. The car's lowered suspension, which features a custom tune for the MagneRide dampers, doesn't hurt - nor do the big six-piston Brembo brakes up front.

Interested? Be prepared to take out another mortgage; the Ford Mustang Jack Roush Edition will set you back $50,995 U.S., plus the cost of the donor Mustang GT - $36,725 or more before incentives. That's nearly $90,000, if you don't feel like doing the math - over ten grand more than the Shelby GT500. But can you really put a price on the pure joy of shifting your own gears?

Just 60 Jack Roush Edition Mustangs will be produced for the U.S., with another 10 earmarked for export.
