2008 Roush P51 Mustang #41 of 151 built The ROUSH Performance P-51Aâ„¢ Mustang was the the highest horsepower Mustang that the company had produced at the time of its release, and represents the first time that internal engine components had been upgraded by ROUSH technicians in their Livonia, Mich., facility. It was determined that the only way to give the P-51Aâ„¢ 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 ROUSHchargerâ„¢ supercharger system. Additional alterations include a custom aluminum upper and lower intake manifold for the high capacity air-to-water intercooler and ROUSHchargerâ„¢. ROUSH installed a custom fuel rail and high-flow fuel injectors, a high-flow capacity fuel system, as well as a dual electronic throttle body. With that the new ROUSH P-51Aâ„¢ engine has a rating of 510 horsepower and 510 lb.-ft. torque. . The changes to the ROUSH P-51Aâ„¢ didn't end under the hood. A ROUSH aerobody kit was 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 comes with ROUSH sport leather seating and custom floor mats, both with an embroidered P-51Aâ„¢ emblem. The white face gauges and billet aluminum pedals will get a lot of use as you bang 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 have also been upgraded with 14-inch front two-piece rotors and four-piston calipers. Each component specifically engineered so that ride comfort was not compromised at the expense of the tremendous gains in performance.
