You may remember last year that Raybestos built a throwback NASCAR clone out of a 1964 Pontiac GTO. It was covered in Hot Rod magazine and there were tons of cool videos on the build-up. We even ran a piece on it in our Optima Ultimate Street Car Invitational shootout coverage in the March 2012 issue. Well, the folks at Raybestos loved it so much, they did it again this year, only they chose to cover the build-up of a blown Roush-built Mustang.
After the build-up, the Raybestos Stage 3 Mustang was placed on Roush’s in-house dynamometer for a final tune, and the results were impressive. The Raybestos "Beast," as the Roush engineering team has nicknamed the car, produced 580 horsepower at the rear wheels. That’s an estimated 670 horsepower at the flywheel. Fresh off the dyno, the Mustang hit the Hot Rod Power Tour, making the long haul in a 1,500-mile drive from Michigan to Texas. Despite being driven hard, the Tremec Magnum XL 6-speed transmission and Moser 9-inch rearend worked their magic to net a very respectable 18 mpg. With that much power on tap, plus legendary Roush handling and an unbelievable Raybestos NASCAR-spec brake package, the latest Raybestos giveaway car has earned its reputation as a beast on the street.
