2010 ROUSH 540RH Mustang

The ROUSH 540RH Ford Mustang features a 540 horsepower powerplant and has limited content. Also known as the Hammer, The ROUSH 540RH Mustang comes armed with massive horsepower, a ROUSH rear decklid spoiler, and short throw shifter with a choice of white or black ball, the 540RH is a stoplight slayer.

The 2010 ROUSH 540RH Mustang 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. The ROUSH 540RH Mustang 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.
