2003 Ford Mustang Cobra - Repeat Contender

Motivation comes from a Kotzur Racing Engines-built 449ci Windsor with a 4.125-inch bore and a Sonny Bryant crank. The 9.1:1 bad boy relies on a Steve Petty-specified Comp Cams valvetrain and Brodix Neal BF202s for breathing. A 105mm throttle body receives boost from twin 80mm Precision turbos, and charge air is cooled by a custom liquid-to-intercooler. At just 25 pounds of boost, horsepower checks in at 1,580 at 7,300 rpm, with 1,200 lb-ft of torque. View Related Article
