NHRA Stock Car drag racing has generally been reserved for vehicles with factory-spec powertrains, but for the first time the rule book is allowing vehicles with aftermarket parts to compete. Two versions of the ROUSH's supercharged powertrains -- the 430 horsepower V8 from the Stage 3 Mustang and the 510 horsepower V8 from the P-51A -- have been approved to race in the Stock and SuperStock classes. The Haas, Carrothers & Wagner Racing team has already lined up to race a ROUSH Mustang and is currently building the car around the Stage 3 powertrain.

When Roush pulled the wraps off its new P-51A Mustang, we ventured a guess that it wouldn't take too long to sell out the 100 being produced for 2008. After all, it's the most powerful Mustang ever produced by Roush at 510 horsepower, and the car's personal connection with Jack Roush's love of both planes and automobiles is sure to make it an instant collector car. Well, it turns out we were right. In fact, Roush has received so much interest in the car that it has bumped the production to 151. It doesn't sound like much until you consider that's more than a fifty percent increase from the originally planned run of 100 cars.

While pricing hasn't even been announced yet, expect an MSRP of just over $65,000. That gets you Roush's latest supercharger, forged internal engine components, a custom lower and upper intake manifold, a custom fuel rail and high flow injectors, upgraded duel throttle body, and a high-capacity intercooler good for at least 510 horsepower. The P-51A also gets a Roush body kit, 14-inch brakes, upgraded interior, 18-inch wheels and tires, and a paint scheme inspired by the 357th Fighters Group that was legendary in WWII.

During World War II, the P-51 Mustang fighter plane helped establish air superiority for the Allies. Jack Roush's latest street Mustang borrows its name from that aircraft and hopes to establish similar dominance on the ground against the "invasion of foreign brands." This is the Roush P-51A Mustang, being introduced to day at SEMA, and it is the most powerful road car (in terms of HP) the company has produced so far. Underpinned by a Roush Stage 3 suspension and driven by a modified, ROUSHcharged 4.6L V8 producing at least 510 horsepower and 510 lb-ft of torque, the P-51A should be more than able to keep pace with its competition. Naturally, a full Roush aero body kit, upgraded wheels and tires, and a brake upgrade are also part of the package. The P-51A isn't shy about advertising its prowess, either, with "510 HP" emblazoned in large block characters on the hood. Incidentally, the yellow and red accent squares on the grille and fenders take their colors from the "Yoxford Boys" of the 357th Fighters Group, Eighth Air Force ETO, which had more air-to-air combat victories during WW2 than any other P-51 group in the Eighth Air Force. Will owners paint competing automakers' logos on the front fenders after each stoplight showdown win? Who knows, but it sure would be in keeping with the theme Roush has going here. That thunder emanating from the exhaust pipes is the sound of automotive patriotism, Jack Roush style.
