2007 Shelby GT500 Mustang - An Evolutionary Tale
|
There are only a few engine modifications thanks to Ford providing a potent, supercharged 5.4-liter bullet. The Evolution Performance gang added a smaller blower pulley, a Stiegemeier-ported Eaton, a JLT cold-air kit, long-tube headers, a custom x pipe system, and a Borla exhaust. SCT software was used to tune the computer, and this mod motor produced 615 hp and 646 lb-ft of torque at the rear tires. A newly designed lower pulley has been custom made and is the first of its kind. With more boost and a 75hp shot of nitrous, the engine made 664 rwhp and 778 rwtq. View Related Article
