CALL LARRY AT 1-800-783-3673 EXT.1246 FOR ALL THE PURCHASE OPTIONS AVAILABLE ON THIS VEHICLE! The 2010 ROUSH® 540RH™ has a new suspension package which includes front and rear springs, front and rear stabilizer bars and jounce bumper, and a subtle tone-on-tone striping package. This vehicle uses the same engine that debuted in the 2009 ROUSH® P-51B™ Mustang. In order to get this type of power from the Ford 4.6L, 3-valve engine, ROUSH technicians replace many of the internal components with stronger parts including forged aluminum pistons (with an increased dish to lower the compression ratio from 9.8 to 8.6), forged steel H-Beam connecting rods and a forged steel crankshaft. The fuel rails are changed, as are the fuel injectors and an upgraded fuel pump. ROUSH® also upgrades the clutch and includes a custom-calibration for the ECM to manage the performance of the next-generation R2300 ROUSHcharger®. Of all the different iterations of the 2010 Mustang I have driven, the Roush 540RH has by far been the loudest, wildest, most impressive of the lot. It's not often that I come across a car that I'm too afraid to use all or most of its potential, but Roush inspired a healthy, thrilling dose of fear, and I found myself piloting it with respectful restraint. Here's why. The 540RH can pull away from a stop in third gear with no difficulty. In first gear, it takes serious concentration to simply maintain traction. First to second is even hairier, with the rear tires breaking loose without a thought, the back end writhing about anxiously while the car is already in motion. Even in third gear, on the highway, I could lay into the accelerator, and could still spin the tires. And, by the way, all this is accompanied by a gut-wrenching, mind-shattering exhaust note that pounds any discursive thought out of your head. In a sense, the car dehumanizes you, and man and machine combine into some sort of angry Tasmanian devil constantly on the verge of berserker rage. Be sure to visit our You Might be a Roush Owner page
