    Even More Power! The 2003-2004 Cobra Mustang came with an impressive 390 Horsepower and 390 lb/ft of Torque from the factory, but after installing this Black 2.3L Whipple Supercharger Upgrade Kit, you'll be planting a ground pounding 475 Horsepower and 440 lb/ft of Torque to the pavement. That's 85 more horsepower and 50 more ft/lbs of torque over stock!

    Aftermarket Oval Throttle Body. This Black Satin 2.3L Whipple is designed for use with an aftermarket oval throttle body. This 13 psi Supercharger Kit does not require PCM, fuel pump or MAF meter upgrades and is a direct bolt on replacement.

    Supercharger Kit. As a complete bolt-on system, the Whipple 2.3L Twin Screw Supercharger requires zero modifications to your engine or PCM. Compressing more air per RPM at lower temperatures and with less parasitic loss, this supercharger offers incredible power levels. It features a discharge plate that offers more plenum area and a larger radius, which distributes air more evenly over the entire intercooler core.

    Application. This Black 2.3L Whipple Supercharger Upgrade Kit is designed as a performance upgrade for the 2003 to 2004 SVT Cobra Mustangs in combination with an aftermarket oval throttle body.

    Please Note: Whipple Supercharger Kits are built to order for our customers. Because of this there can be a 10 to 14 day lead time on orders.

    Will this fit my 99 cobra ?


    • This will fit with your 1999 Cobra however you will need all of the 2003-2004 Cobra parts to make this work. You will need the lower intake manifold, heat exchanger, intercooler core, vacuum/boost lines, solenoids, timing cover, power steering relocation, etc.

    I have an 01 cobra I building and was wonder if I could use this whipple for my engine type 4.6 4v ?


    • This will need many different modifications for it to fit on a 2001 Cobra. Things like a lower intake manifold and a lower intercooler. Also, you will need the timing chain cover, heat exchanger, MAF, cold air intake, and other parts from a 2003-2004 donor Cobra. It will not be an easy build to complete.

    Will this supercharger fit my 2002 GT with a 4.6L 2V V8?


    • This is designed as a performance upgrade for the 2003 to 2004 SVT Cobra mustangs only.

    im trying to get a t/c supercharger for my mach 1. would this work, i know i need alot more stuff.


    • This supercharger is specifically an upgrade for an already supercharged 03-04 Cobra. We offer a Procharger that is sold as a complete kit, so basically as close to a "bolt on" supercharger as you can get.

    I wanted to know if this would fit my Lincoln Aviator 2004 4.6L. I understand that it uses the same engine from the 99' SVT Cobra and this is an upgrade from the OEM supercharger. So I'd rather be safe then sorry when it comes supercharging my vehicle.


    • yes it will fit im ordering roughly the same part for my 04 GT and if your motor is the same as mine it will fit but it is aftermarket so no guarantee that u will have a flawless install though some part are that way. good luck with your build.

      This supercharger is fantastic. My '03 cobra is so much more intimidating and the engine looks great with the black finish. 10/10 would recommend

      Installed this my self

      I did this install myself in my garage with only a few hours a day after work last week. Was fairly easy. The instructions were good but I would advise not to follow the instructions for the removal on the stock supercharger. Its nearly impossible to pull the entire unit out by your self. Instead remove the supercharger from the lower intake and coolant hose bracket from the front , that was the only issue i ran into. I haven't been able to drive it yet due to needing a tune but everything fit like it should .
