Roush Phase 1 to Phase 3 675HP Supercharger Upgrade Kit for 2011-2014 GT Mustangs with a Roush Supercharger and Manual Transmission.
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.
Primary Components Include:
- 80mm Supercharger pulley
- Roush fuel pump voltage regulator with Roush plug-n-play wiring harness
- Cold air induction system
- 2085mm 6-rib serpentine belt
- Unique Roush PCM calibration
*Does NOT fit the Boss 302.
