The Roush 2011-2014 5.0L Ford Mustang Phase 2 Calibrated Supercharger Kit is part of the TVS (Twin Vortices Series) line of superchargers developed by Roush, setting new standards for performance and reliability. This is the same line that has been used and proven for years in Roush-built Mustangs and F-150 vehicles.

Countless hours of research and testing contribute to the development of Roush superchargers, including assessments in extreme environmental conditions ranging from -20 degrees up to and through 120 degrees Fahrenheit and at altitudes as high as 14,000 ft for quality and performance. Over 40 emissions tests are conducted to ensure that the Mustang maintains consistent emissions and that all Ford engine diagnostics functions as intended. However, please note that this kit is currently not CARB approved. Engine dynamometer development allows for the re-map of camshaft positions and various other aspects of the calibration.
