ROUSH Stage 3 Production is Underway



The empty engine bay on the 2010 Ford Mustangs can only mean one thing – ROUSH® is in the process of turning this car into Stage 3™ fire breather. The first step in transforming the stock 315 horsepower 4.6L V-8 engine into a 540 horsepower monster is pulling the engine out.

From there, ROUSH® technicians perform an extensive internal rebuild. This includes replacing 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®.

Look for the first 2010 ROUSH® Stage 3™ Mustangs to hit the dealerships by the end of the month, right on schedule. The 2010 ROUSH® 540RH™ will follow shortly, hitting the streets in October.
