More Horsepower! The stock V6 Mustang came with a decent 193 Horsepower and 225 lb/ft of Torque from the factory, but after installation a ProCharger-equipped 3.8L V6 Mustang can make 60-80% 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 2-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, ProFlow bypass valve, and a computer chip.

Application. This ProCharger Stage II Intercooled Supercharger System is specifically designed for use on the 1999 to 2003 V6 Mustangs equipped with the 3.8L engine.

Technical Note. The ProCharger kit does not include fuel injectors and will require the use of 39.5 lb/hr fuel injectors, ProCharger part #FI001I-039.

Is this a complete kit with everything you need? If I were to purchase this would I be good to go? More specifically do I need to buy a blow-off valve? Intercooler? etc... in order to have this 100%set up ready to ride after install? I am in the market for an item such as this and want to make sure I have everything lined up before the install. Any comments would be greatly appreciated!


  • Yes this is the complete kit

does stage ll kit include fuel injectors and if not,do you offer them?


  • It does not include injector because this kit is for a stock V6. You can buy injectors if you plan on raising the boost. Injector size will depend on your horsepower levels you intent to target, along with what kind of fuel system upgrades you do. American Muscle does sell upgraded injectors.

For the ProCharger stage 2 for the 99-4 v6 mustang Can you put the boost high then 11 psi or is that the highest?


  • 9-11 PSI of boost is for this kit only since its intended for a stock V6. If you upgrade your fuel system, slap a smaller pulley, and get tuned, you can run more boost.

how well will procharger stage 2 intercooled supercharger work on a fully rebuilt and built engine from the bottom up like has new crankshaft, flat top pistons, rods lifters, valves, rocker arms, cam, intake throttle body, headers the hole nine yards how much will it gang with this on or how much work wuld it be to get it to work right on my engine??????


  • Best time to put this on is a new engine. The engine will break in and be matched to forced induction!

After everything is installed, your saying that I can run 9-11 pounds of boost without a tune? On a stock engine, adding more than what the factory intended it to handle.


  • Yes. But they will give you a tune. You send them your computer with what all is done to the car. And they tune it accordingly. Reccomend a wideband a/f ratio meter so you can make sure it's not to lean or rich. I would also go get it dyno tuned if able just cause they can get more hp out of it with some dyno runs.

    The supercharger does the job. Added a bunch of power I needed for tx2k16. Haven't gotten it dumped yet so I don't know what it has added in terms of numbers.
