Why The Roush Stage 3 Mustang Is Worth Every Penny Of Its Supercharged Awesomeness


The final price tag is still a horsepower bargain.

No stranger to making Ford Mustangs even more powerful and special, Roush Performance has just announced official power ratings for its new Mustang Stage 3 which, according to the famed tuner, "is the most powerful and well-balanced production Mustang to launch out of the ROUSH Performance garage." Beginning with a stock Mustang GT and its 5.0-liter V8, the crew at Roush have added a 2.3-liter TVS supercharger that now churns out a total of 670 hp and 545 lb-ft of torque.

For comparison, the stock Mustang GT has an output of 435 hp and 400 lb-ft. Roush has also given the car a Quad-Tip exhaust (with optional Roush Active Exhaust System), standard single-adjustable coilover suspension system, and an aero body kit.

There’s also race-inspired graphics, wheels, and grille work. Roush claims the RS3 Mustang "truly bridges the gap between road car and race car, putting drivers behind the wheel of the ultimate uninhibited muscle car." Pricing starts at $21,995, not including the price of the donor Mustang GT, which’ll cost you at least $32,300.
