More Horsepower! The stock GT Mustang came with a respectable 300 Horsepower and 320 lb/ft of Torque from the factory, but after installation a ProCharger-equipped 4.6L Mustang can make 70-75% more horsepower at the flywheel. Thanks to the industry’s coolest charge air temperatures, the unmatched power gains are delivered with maximum reliability and everyday drivability.

High Capacity Intercooler. If you have the desire to continue modding your Mustang even after adding a ProCharger Supercharger, then this is the Kit for you. The 3-core air-to-air intercooler included with the Stage II Kit has a higher capacity than the High Output (HO) Kit. This Stage II kit will accommodate additional modifications as you continue to transform your Mustang into the highest horsepower beast possible.

Complete Kit. The ProCharger Stage II Intercooled System comes 100% complete, and includes ProCharger self-contained supercharger, air-to-air intercooler, intercooler tubing, brackets, 39 lb/hr fuel injectors, ProFlow bypass valve and a computer programmer.

Application. This ProCharger Stage II Intercooled Supercharger System is specifically designed for use on the 2005 to 2009 GT Mustang equipped with the 3 valve 4.6L modular engine.

Will this prochrger for on to a 2009 Bullitt? It wasn't listed so I wanted to make sure before I go towards this setup.


  • Just so there is no confusion there is no such thing as a 2009 Bullitt. During the S197 body they ran only for one year 2008. That is why they don't have a listing but it will fit a 2009 GT.

How will stock internals and transmission hold up with this?


  • Your stock internals will be fine with the Procharger Stage II Intercooled Supercharger System (05-09 GT). I would recommend getting an upgraded clutch. However when you start upgrading this kit and running more boost, then you will need to start upgrading your internals.

Question Resolved

What's the difference between the high output and the stage 2? Which one is the safest route for a stock internal engine?


  • The Procharger Stage II Intercooled Supercharger System (05-09 GT) will have a 3-core air-to-air intercooler included with this Kit, it has a higher capacity than the High Output (HO) Kit. The safest route for a stock car would be the Procharger High Output Intercooled Supercharger System (05-10 GT) item number 80813

Question Resolved

Will I have to install a new fuel pump or does this kit include a fuel pump upgrade?


  • The Procharger Stage II Intercooled Supercharger System utilizes a fuel bump booster, so the stock fuel bump can be used. If you were perhaps interested in running an alternative fuel, or planning to make more power, which would require more fuel, we would recommend a fuel pump with a larger flow rate.
