(October 30, 2007) ROUSH Performance unveiled the 510-horsepower and 510 lb.-ft. of torque P-51A Mustang automobile Tuesday at the SEMA Show in Las Vegas.

"I've often said that there was never a Mustang built that I didn't like and that includes both the car and the airplane," said Jack Roush, an aviation enthusiast who currently owns two P-51 Mustang warbirds. "This is the type of product that ROUSH has wanted to produce for at least 10 years but the right platform, the right technology, and the right timing never intersected until now."

The ROUSH P-51A is easily the highest horsepower Mustang the company has ever produced and represents the first time internal engine components have been upgraded by ROUSH technicians in its Livonia, Michigan, facility. It was determined that the only way to give the P-51A moniker its due was to completely break into the 4.6L, 3V and rebuild several of the functional internal components, which include a forged steel eight-bolt crankshaft, forged aluminum pistons with increased dish to lower the compression from 9:8 to 8:6, and forged steel H-Beam connecting rods. These upgraded parts were necessary for the stock Ford engine (which comes with 300 horsepower from the factory) to be able to withstand the additional power generated from the newest iteration of the legendary ROUSHcharger supercharger system.

Additional alterations include a custom aluminum upper and lower intake manifold for the high-capacity air-to-water intercooler and ROUSHcharger. ROUSH installs a custom fuel rail and high-flow fuel injectors, a high-flow capacity fuel system, and dual electronic throttle body.

The changes to the ROUSH P-51A don't end under the hood. A ROUSH aerobody kit will be installed, which includes a front fascia, chin spoiler, hood scoop and rear spoiler. The ROUSH black high-flow grill is added along with cooling side shields to give the car the aggressive look it needs while stalking the streets.

Internally, the car will come with ROUSH sport leather seating and custom floor mats, both with an embroidered P-51A emblem. The white face gauges and billet aluminum pedals will get a lot of use as the driver bangs through the gears with the ROUSH short throw shift lever and retro black ball.

For those who look behind the 18-inch ROUSH forged five-spoke wheels will see the vaunted Stage 3 suspension underneath this vehicle. Designed to handle even the tightest twists and turns, this suspension includes specially-engineered and tuned front struts, rear shocks, front and rear springs, front and rear sway bars, and jounce bumpers. The front brakes are also upgraded with 14-inch front two-piece rotors and four-piston calipers. Each component was specifically engineered so that ride comfort was not compromised at the expense of the tremendous gains in performance.

Pricing for the ROUSH P-51A Mustang has not been set, but will be announced shortly. The vehicle is slated to begin production in the first quarter of 2008 and will be limited to 100 vehicles. As with all ROUSH vehicles, the P-51A will carry a 3-year/36,000-mile warranty.
