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.

I bought a lot used from someone. It's a little older with a different procharger however, it's self-contained and has about the same specs as the p1sc. I has LT, jlt intake, and cams and put down 346 ...

How will stock internals and transmission hold up with this?

ericknoerdel

  • 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.

Is this charger better than http://www.americanmuscle.com/roush-r2300-phase-2-supercharger-0509gt.html

GCHS

  • It really comes down to personal preference honestly. The first thing that is different is that the ProCharger is a Centrifugal style supercharger which will have you relocate where your cold air intake is whereas the Roush supercharger is a Root style which will install where the intake manifold is located leaving you to not reposition anything besides the cold air inlet tube and throttle body. Secondly, the ProCharger will (with a tune) gain you between 70-75% HP (between 510-525 HP) and the Roush is rated at around 550HP. Both of the superchargers will come with reprogramming. ProCharger will include their own programmer and Roush has a PCM Flash Voucher card which can be used to rewrite over 200% lines of code within your cars computer over the competition. Lastly, price and installation time. While the Roush is more expensive than the ProCharger it is also an easier install than the ProCharger. As always with superchargers, mechanical expertise is required and you can expect the installation time to last about a full day to have it completed.

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

SWD

  • 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

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

Ovalman62

  • 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.

Would this kit be safe for a stock bottom end on a GT that is driven HARD and at the track every other weekend? I want this kit but have debated on building a forged bottom end for it first due to my driving habits.

Chris

  • Since you use this car at the track every weekend, it is recommended to build up the bottom end. Forged internals would be a perfect fit for you. This will prevent the engine from becoming severely damaged. If you are going with this kit and using the car for the track, it is highly recommend to upgrade the internals.
