When the ROUSH Stage 3 Mustang debuted back in May of 2015, it bridged the gap between being a road car and a race car. With 670 horsepower and 545 lb-ft of torque straight from the factory, the ROUSH Stage 3 put drivers behind the wheel of the ultimate uninhibited muscle car and proved that the new S550 platform could challenge any of its musclecar rivals.

The ROUSH-upgraded Mustang proved to be a popular upgrade, and much of that success was due in part to the efficient pairing of Ford’s 5.0-liter V8 engine and ROUSH Performance’s 2.3-liter TVS supercharger. Fast forward to 2018, and this first-generation ROUSHCharged S550 remains a potent package for enthusiasts to enjoy. Yet, thanks to advances in supercharger technology, upping the boost on this popular platform is as easy as making the switch to the new Eaton 2650 rotor assembly.
