ROUSH Unleashes 575 hp Supercharger and Upgrade Kit

2013 Ford Mustang SuperchargerThe new ROUSH® Ford Mustang Phase 1 Supercharger Kit (Part# 421388) and Phase 1 Supercharger Upgrade Kit (Part# 421387) are calibrated to deliver a tire-melting 575 horsepower and 505 lb-ft of torque to the 2011-2013 5.0L-4v V8 Ford Mustang manual and automatic powertrains, an increase of 155 horsepower and 115 lb-ft over the stock Mustang.  In addition to the boosted power levels, ROUSH’s new Phase 1 supercharger calibration is designed to produce greater low end torque and provide increased throttle response for better off-the-line performance.

The ROUSH 2011-2013 5.0L Ford Mustang Phase 1 Calibrated Supercharger Kit is part of the TVS (Twin Vortices Series) line of superchargers developed by ROUSH that have raised the bar for performance and reliability. This is the same supercharger line that has been used and proven for years in ROUSH-built Mustangs.  The ROUSH R2300 supercharger features Eaton's new rotating assembly with cutting-edge TVS technology that delivers more power and better fuel economy in a smaller package for uncompromising performance.

The ROUSH Phase 1 Mustang supercharger kit is protected by a limited parts warranty (ROUSH supplied parts), which is for 3 years or 36,000 miles from retail purchase date.  An optional 3 year/36,000 Mile Complete Powertrain Warranty is also available, which is for 3 years or 36,000 miles from the original Ford vehicle in-service date.  Please contact ROUSH customer service for more information at 1-800-59-ROUSH.

ROUSH Phase 1 Upgrade KitThe ROUSH Phase 1 Supercharger Upgrade kit allows current owners of 2011-2012 ROUSH Superchargers to take their current 525 or 540 horsepower kits to the new 575 horsepower calibration with new pulley and belt.  The phase 1 kit will keep your ROUSH 3 years or 36,000 mile complete drivetrain warranty on the original supercharger system.

The 575 horsepower Phase 1 Supercharger Kit and Phase 1 Upgrade Kit are currently not available for sale or installation in the state of California.
