Will the stock fuel pump with 47lbs injectors be able to keep up with the fuel needs using the 74mm pulley with a stage2 r push charger and long tube headers or will I need to upgrade the pump/ buy a boost-a-pump


  • This C&L Performance Supercharger Pulley is specifically designed for use on the 2011 to 2014 GT Mustangs equipped with the Roush Twin Vortices Series Supercharger. Your stock fuel pump should be sufficient.

Do you need to upgrade your injectors to run the 74mm pulley. I'm using a Roush stage 3 on my gt.


  • injectors are not typically required with the C&L Supercharger Pulley, but this will depend on your current injector size as well as all other mods done to the car that will effect the final horsepower output.

2012 gt what size is the belt that goes with the 75mm pulley 800 mm 805 mm? what comes with the kit.


what size belt would you use with the 75 mm pulley?


  • The C&L Supercharger Pulley would utilize the stock belt length unless additional pulley changes have been made.

Can you pair this with a bama tune on a 2014 roush


  • As of right now, Bama does not offer tunes for Superchargers. I would keep checking back in the future in case this changes!

    91 Octane

    It was very hard to find 93 octane fuel so reduced from an 80mm to the 82mm Good for about 8 to 10 lbs of boost
