    More Horsepower! The stock GT Mustang came with a decent 260 Horsepower and 302 lb/ft of Torque from the factory, but after installation a ProCharger-equipped 4.6L GT Mustang can make 55-60% 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. 

    Superchager Kit. The ProCharger HO Intercooled System comes 100% complete, and includes ProCharger self-contained supercharger, air-to-air intercooler, intercooler tubing, brackets, 39 lb/hr fuel injectors and ProFlow bypass valve.

    CARB Certified. Best of all this ProCharger High Output Intercooled Supercharger System is 50-state smog legal under CARB EO # D-365-5.

    Application. This ProCharger High Output Intercooled Supercharger System is specifically designed for use on the 1999 to 2004 GT and Bullitt Mustangs equipped with the 2 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 support@americanmuscle.com with your Order Number in the Subject line, so the order can be processed.

    What if I have an off road x pipe and gears? do i need the upgraded kit?

    • Having any modification other than a catback, yes you would want to get the upgraded tuner kit. When you have an off-road catless mid-pipe and gears, they both need to be tuned for recalibration. This supercharger kit can not accommodate for those modifications while the tuner kit can. Tuner kits will allow for more modifications and will get you the best performance from you Stang, which is the main goal of supercharging your car!

    What exactly is the "tuner kit" What do you mean by tuner kit. Is it an option you purchase......or is it that form u fill out so they can program the chip that comes with kit

    • Tuner kits are the same as complete systems except without any fuel system upgrades or ECM reprogramming. This allows for custom tuning and fuel mods that the tuner or racer may prefer.

    Can i install this along with bbk long tubes? do i just need a custom dyno tune instead of the one they provide?

    • Yes, this kit is going to work with long tube headers. You would need to get a custom dyno tune, as the one from Procharger wouldn't work if your Mustang isn't stock.

    If I bought this kit, with me running FBO's, I cant run the tune procharger provides. Could I still run this kit with a custom dyno tune?

    • The Procharger High Output Intercooled Supercharger Kit can be run with a dyno tune.

      procharger a pro pain in the neck

      I'm not even sure where to start with is one. This had to be the most miserable auto project I've ever taken on. Lets start with "easy installation", quoted directly from prochargers brochure. That is a flat out lie. It would only be true if their instructions manual was complete and comprehensive, which it is not. I downloaded and read the manual before i purchased. Seemed pretty easy. When you actually start to follow the instructions you will find much ambiguity and failure to inform you that things like supplied brackets need to be drastically bent, and the photos supplied don't look like a 2000 gt and the kit on the pic is not what I have. Next problem was bad/wrong parts. I received a bad MAF flange with numerous holes in it from a poor weld job. The supplied rad overflow support was stripped. Wrong bolts (too short) were supplied for MAF to flange bracket. Wrong bolt (wrong size) provided to brace supercharger from timing cover. While Procharger did replace the parts, it was a series of shipments and this greatly delayed my project. You can only work so far ahead before you need the parts to go on to next step. Also annoying was that each deliver from procharger, even a $1 bolt is done requiring a signature so plenty of my time wasted waiting for my parts at home. There are also fitment issues that I have not yet fully resolved. Procharger calls for the the upper Rad hose to be trimmed to fit. Well not even close. The pics sent by tech support don't even look like my car.They seem fine with the hose hard against the supercharger and the inlet pipe resting on hose. I bought another hose and a coupling and made my own that does not rub. The supplied air filter is too long and must be squashed about an inch to fit where they say. Again, tech support pics show a mustang but it don't look like mine. I have found one from KandN that will work, and that's going to cost me $65. Tech support unwilling and unable to help solve this problem. The supplied Diablo Tuner would not load my tune. Needed to send a replacement. Hats off to them for an overnight replacement and good tech support. Was about a three hour job on phone with them to get the tune installed. By far the problems were compounded by poor support from Procharger. I have had to make dozens of calls to them for help with fitment/parts and though I liked each and every one of the tech guys, at the end of the day they "didn't know what else to tell me", as related to the air filter, rad hose, intercooler bracket modifications. Most distressing of all is that they offered apologies, because this has never happened before. I have turned a few wrenches in my day, and got all my mechanic friends to look at this along the way and they aren't impressed either. If the parts don't quite fit, then since 2000 they have had plenty of time to update manual and their overall database to be aware of and be in a position to help. In other words, this cant be the first 2000 where things don't fit. And if you are wondering if the car may be tweaked, wonder no more. I ordered this car new in 2000 and have been only owner, currently 8k miles. I'm not filling in the time to install box because it don't go up to 3 weeks. Lastly, the tune. Prochargers "tune" guys are too important to speak with you on the phone. They prefer emails, but do a terrible job responding. When I started the car, the high speed fan ran constantly. I was a nightmare to get the tuner to call me and explain this. I also had flood on hot start and they told me to take it to a tuner. I told them that my $5200 kit comes with a tune and that I intended to get one. So I have very low confidence level in procharger and their "tune". And its been a week since I emailed tuner last and no reply. I'm finally about to take it up with American Muscle as Prochager has just worn me out. It would appear that I'm going to have to find a shop and pay $$$ for a dyno tune anyway. And if anyone is interested, I have chain of emails a mile long to document this process. The supercharger does pull pretty good though.

      Procharger

      Bought a 2002 Mustang GT with a P1SC Procharger. It is super loud and extremely noticeable. I got 410rwhp and 420 torque with the procharger and some other boltons stock motor. If you like people staring at your car when you pull into anywhere like grocery store or wherever, you WILL get someone looking at you. Great product
