      More Power! The stock 1999 to 2004 GT Mustangs came with a healthy 260 Horsepower and 302 lb/ft of Torque from the factory, but after installing a Vortech System you will be planting a ground pounding 364 Horsepower and 371 lb/ft of Torque to the pavement. That is 104 more horsepower over stock!

      Complete Kit.
      This Vortech Mustang Supercharger System comes with all the required parts needed to upgrade your pony to a snarling beast. The kit features fuel management upgrades including a high-flow fuel pump and high-capacity fuel injectors. Also included is a voucher and shipping label to mail your stock ECM directly to Vortech so they can install the appropriate program.

      Application. This Satin Vortech Supercharger System is specifically designed for use on the 1999 to 2004 GT 4.6L V8 Mustangs.

      Shipping Note: This product can not be shipped to an APO/FPO, Guam, Hawaii, Puerto Rico, Alaska, the US Virgin Islands or Canada addresses.

      Technical Note. This Supercharger Kit is designed to be used on stock applications, as Vortech will only provide a tune for the stock motor with stock exhaust or most aftermarket 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..., Vortech will not be able to provide a tune for your modifications. Modified cars will require custom tuning. Also vehicles with ECU codes of RKN or MDE will not be supported by Vortech, custom tuning will be required for operation.

      Please Note. Vortech Supercharger System are built to order by Vortech for our customers. Because of this there can be a 5 to 7 day lead time on orders.

        Good product

        This kit took some light modifications to put on the car. After a dyno tune the car made 370 hp & 362 tq. Not bad for a mostly stock motor.

        Vortech V3

        Good product expected fitment to be a little better but still went together with little problem. The base tune from Vortech wasn't great very rich. If you install this kit DO NOT run the supplied tune get it tuned on the dyno! You can do damage to engine if the tune isn't right. I got 336rwhp and 355 lbs of torque @ 6000rpm.

        Vortech 3V

        I had the kit pro installed and glad I did. I sent in my ECM to be chipped. When all done I had 360 RWHP and 380lb/tq but my car was running super lean. I had it dyno tuned and took out the chip they sent me. I now have 404 RWHP and 398lb/tq. Make sure to do the oil changes frequently or the system will burn up

      5 Top Rated Questions

      Is this compatible with the twin turbo and shaker? I want to put the shaker, this supercharger, and the hellion twin turbo kit on my 01 Bullitt. Will it all work together?

      • you can use the shaker but its just for looks, this is for forced induction in which the shaker may work a bit with some modifications, and as for the twin set up, the only way you can run a supercharger with twins is with a top (whipple) mounted set up which it creates compound boost, but you will have to have a strong well built engine with deep pockets as well

      Installation and Extra Parts? What would the installation cost at a shop? And what additional parts would I need to also get installed to run properly and handle all the additional power?

      • The install can range anywhere from 800-1000 and even more if you get it custom dyno tuned. (Which is needed) The parts you need are the fuel injectors which are included and the fuel pump also included. But you will need to buy an 90mm MAF Which is sold on this site. They should include this but they don't without it things will go very wrong. Other then that you are good to go

      Will i have to upgrade my MAF? I have a 80mm. The picture description could show more than just the vortech. So does this come with the intake hoses?

      • The Vortech Supercharger System is a complete system, and will not require any additional components, such as a larger MAF housing. A full listing of parts can be found here:

      what size fuel injectors does it come with?

      • 1999 models include 30 lb. injectors. 00-04 models include 38 lb. injectors.

      So this kit comes with a tune that works for a stock motor, Will I need to get it dyno if I keep it stock with this kit and the tune that is already in the kit?

      • If you have the stock motor you would not require a dyno tune for this. 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..., Vortech will not be able to provide a tune for your modifications.

      it says if you make any changes it needs to be retuned. my question is 1. does it NEED to be retuned if its tuned for cats but then you take them off. 2. if i have cutouts does that affect it (ran just for fun opened every once in awhile). 3. is there any way you could have more then one tune so you could just load the tunes for each of the changes (for cats and no cats) 1 answer
      I have a 2000 gt with these mods: xe270ah comp cams with notched piston to fit the new lift, new comp beehive springs, new valves, (soon new fuel rails) bbk cold air intake, bbk intake plenum and throttle body, Ford racing Intake manifold, accept coil on plug kit, full exhaust headers back, stage 2 clutch, lightweight flywheel and of course it went to the dyno and got tuned. I was told my compression was increased but I'm gonna get that checked again. My concern is will I run into issues with this supercharger kit paired with my cams. I know I would have to go and get it tuned again of course but will I be ok afterwards 1 answer
