Phase 2 625 HP Supercharger for 2011-2013 Mustang, Go Faster!

ROUSH Performance has launched its 625 hp Phase 2 supercharger and upgrade kits

ROUSH Premier Mustang

Does the Phase 1 Supercharger (525-575hp) leave you wanting more power? We’ve got you covered with our Phase 2 Supercharger and Upgrade Kit. Delivering a tire shredding 625hp and 525lb-ft of tq we have given the supercharger more power using a unique ROUSH calibration and air intake (as well as a pulley and belt if not using a Phase 1 565/575 kit). The calibration works with the intake to bring in more air providing bigger power gains. This Phase 2 Kit is made for automatic and manual 2011-2013 Mustang GTs, except Boss 302 and Laguna Seca, which requires custom install and calibration not available currently by ROUSH. Upgrade Kit works on 5.0L 2011-2013 Mustangs using 525-575hp ROUSH Superchargers.
