Product Description

Roush Phase 2 to Phase 3 675HP Supercharger Upgrade Kit for 2011-2014 GT Mustangs with a Roush Supercharger and Manual Transmission.

Roush's Phase 3 Supercharger Upgrade Kit is calibrated to deliver 675 hp and 585 ft/lb of torque. This power-adder upgrade increases your 625 hp/525 ft/lb Phase 2 Roushcharged Mustang for more tire spinning fun!

High horsepower can't be made without the proper supporting modifications and Roush made sure to take care of everything. A fuel pump voltage regulator and plug-n-play wiring harness were developed to help protect against extreme fuel-to-air changes and possible engine damage. The plug-n-play wiring harness allows for easy installation or removal if the kit ever needs to be removed. No cutting or splicing of factory wiring or harness is required.
