    Features & Details

    • Complete Kit - Tuner Included
    • 70-75% More Horsepower
    • P-1SC-1 Supercharger
    • 10 psi of Boost
    • 3-Core Air-To-Air Intercooler Included
    • Designed for Stock Applications Only
    • Fits 2005-2009 4.6L GT Mustangs
    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.

    Technical Note. This Complete Supercharger Kit is designed to be used on stock applications, as Procharger will only provide a tune for the stock motor with stock exhaust or most aftermarket axle-back and cat-back exhaust systems. If your vehicle is no longer stock and has been upgraded with an aftermarket throttle body, cold air intake, headers, off-road mid-pipe, etc..., Procharger will not be able to provide a tune for your modifications. For modified vehicles, it would be best to purchase a Tuner Supercharger Kit so you can have a local Dyno Shop custom tune your vehicle with your aftermarket upgrades.

    Please Note. Procharger Supercharger Systems are built to order for our customers and accordingly, we require you to submit additional information about your vehicle using this form. Because of this there is a 14 day lead time on orders once your information is received.

    Once the Customer Information Form is filled out, please email it to with your Order Number in the Subject line, so the order can be processed.

        Is this charger better than

        • 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.

        Intake tube vs Strut Tower brace Will strut tower braces clear the intake tube/filter above the valve cover?

        • I would call the brace manufacturer to make sure but in my experience I had no problems. Rodstoy

        I have the Ford Racing intake manifold and like the way it looks so I was thinking on going pro charger but I think that boost comes in later and I have cams also that moved to power curve up in the higher RPMs so I'm looking to recoup more of the lower end torque back. Do you suggest go with the ProCharger setup so I can keep the frpp intake manifold and all ready spent money on that or would you recommend going with a root Style supercharger for more of the instant torque when you hit the pedal since I have cams? Trying to figure out the pros and cons of both superchargers it's a lot of money and want to make the right decision

        Does this kit require changing out the maf or will it be sufficient with proper tuning?

        • This kit would not require you to switch out the MAF. The tune included with this kit would be sufficient for the stock Mustang.

            Its worth it

            The kit is very straight forward, piecing everything together was the most time consuming part. It comes with complete instructions but at times you find yourself just going with it and getting ahead of the instructions. The floating thermostat was the most difficult part for me, be careful with the factory hose clamps. I sheared one of the ears off and it took up 2 hours of my time because it was hard to get to. I recommend reading the tuning section of the book because you have to email your factory tune to procharger, then they email you a modified tune which could take 24 hours..they got it back to me in like 4 hours.

            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 to the wheel. With the procharger I'm running 538 to the wheel on 10psi.

            went from 276rwhp to 432rwhp...the blow off valve sounds amazing!! had to make some room for the new air intake but fits snug.
