LIVONIA, Mich. (September 9, 2008) – Historically, the National Hot Rod Association has only approved powertrains for competition as they come from the factories in Detroit, but all that changed with the recent approval of the 2008 ROUSH® supercharged 4.6L V-8 in the Stage 3â„¢ and P-51Aâ„¢ Mustangs. It is believed that this is the first time the NHRA has approved an aftermarket powertrain for competition.

The ROUSH Mustangs will be allowed in the NHRA Stock and SuperStock categories as determined by the horsepower and shipping weight of the two vehicles. Coupe or convertible chassis will be allowed with a horsepower of 430 for the Stage 3 and 510 for the P-51A. The shipping weight of the ROUSH coupes is 3316 pounds, while a convertible weighs in at 3443 pounds.

Depending on the combination of coupe or convertible and the ROUSH Stage 3 or P-51A powertrain, the cars would be classified between AA Stock and B Stock or SuperStock A and F. For further details regarding the authorized modifications and safety requirements consult the NHRA rule book or visit www.NHRA.com.

It is anticipated that the first team to campaign a ROUSH Mustang in NHRA competition will be Haas, Carrothers & Wagner Racing. The team, which has won three consecutive NHRA Division 3 championships (2004-2006), is currently building a ROUSH Mustang with a Stage 3 powertrain.

“As many people know, I first began my motorsports career in drag racing and had a lot of success in the NHRA over the years,” said Jack Roush. “I never lost my interest in the sport and have continued to follow it with great enthusiasm since moving on to road racing and now stock cars. I think it is going to be very exciting to see a ROUSH Mustang breaking the beams on the starting line and I really look forward to the day one of our cars captures that first ‘Wally’ (the nickname of the trophy awarded in NHRA competition in tribute to Wally Parks, the founder of the NHRA).”

PRESS RELEASE:

When Jack Roush pulled off the cover and unveiled the new 510-horsepower ROUSH P-51A Mustang at the SEMA Show in October, it took just moments before the telephones started ringing at the offices with dealers and consumers clamoring to get hold of the muscle car.

Although the ROUSH order bank isn’t scheduled to open to authorized Ford dealers with final pricing until January, 2008, the post-announcement interest was enough for ROUSH management to re-assess the total number of ROUSH P-51A Mustangs that will be released to the public. Consequently, ROUSH Performance has decided to increase the production run to 151 units when these start build, anticipated to be the first quarter of 2008. It was previously announced that the production volume would be limited to 100 units.

“Certainly we anticipated that the ROUSH P-51A Mustang would be a popular car and sell quickly to our dealer base,” said Joe Thompson, general manager of ROUSH Performance. “But I must say that we were a little surprised at just how fast the demand grew for this car so we worked with our suppliers to make ensure that an increased volume would be possible and can now announce that there will be 151 vehicles produced next year.”

The ROUSH P-51A is easily the highest horsepower Mustang that the company has ever produced, and represents the first time that internal engine components have been upgraded by ROUSH technicians in their Livonia, Mich., facility. The stock Ford 4.6L, 3V engine will see a rebuild of several of the functional internal components, including 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, as well as a dual electronic throttle body.

The new ROUSH P-51A engine has a preliminary rating of at least 510 horsepower and 510 lb.-ft. torque. It is anticipated that final figures may even be slightly higher than this when final testing and calibration is approved by the ROUSH engineering staff. As with all ROUSH vehicles, the P-51A will carry an industry-leading 3 year/36,000 mile warranty.

Based in Livonia, Mich., “The Art of Performance Engineering” takes place at ROUSH Performance.

During World War II, the P-51 Mustang was hailed as a savior of aviation and certainly played a major part in ending the conflict. This long range fighter escorted Allied bombers over Europe and Hermann Goering, the head of Germany’s Luftwaffe, summarized the plane’s role by stating, “The day I saw P-51 Mustangs flying over Berlin, I knew the jig was up.”

Today, at the SEMA Show in Las Vegas, the jig is up for the rest of the Ford Mustang tuners as ROUSH Performance unveiled the P-51A Mustang automobile which, at 510 horsepower and 510 lb.-ft. of torque, is sure to be held in as high a regard as the airplane has been in the history books and will help to save the streets from the invasion of the foreign brands.

“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 that the company has ever produced, and represents the first time that internal engine components have been upgraded by ROUSH technicians in their Livonia, Mich., 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 ROUSHchargerTM supercharger system.

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

The new ROUSH P-51A engine has a preliminary rating of at least 510 horsepower and 510 lb.-ft. torque. It is anticipated that final figures may even be slightly higher than this when final testing and calibration is approved by the ROUSH engineering staff.

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.

As an interesting side note, the yellow and red accent colors on the vehicle come from those used by the 357th Fighters Group, Eighth Air Force ETO (European Theater Operations) who were unofficially known as “The Yoxford Boys” after a village near their base. Its victory totals in air-to-air combat are the most of any P-51 group in the Eighth Air Force and third among all groups fighting in Europe. The 357th flew 313 combat missions between February 11, 1944 and April 25, 1945 and is officially credited by the US Air Force with having destroyed 595.5 German airplanes in the air and 106.5 on the ground. Pilots in this group included Captain Clarence E. “Bud” Anderson who flew a P-51 named “Old Crow.” One of Roush’s personal P-51 fighters is painted as a replica of this airplane.

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 an industry-leading 3 year/36,000 mile warranty.
