    Product Information

    Features, Description, Reviews, Q&A, Specs & Installation


    • 2.9L Twin Screw Crusher W175ax
    • Whipple Supercharger
    • 20-21 Psi of Boost
    • Black Satin Finish
    • Bolt-On Replacement
    • Includes 170mm Mono Blade Throttle Body
    • Includes 123mm Slot Style MAF Cold Air Intake Kit
    • Fits 2003 to 2004 SVT Cobra


    Even More Power! The Terminator Cobra came with an impressive 390 horsepower and 390 lb/ft of torque from the factory. This Black Crusher 2.9L Whipple W175ax Supercharger Kit is optimized for high boost levels on both stock or heavily modified 2003-2004 Cobras and will be more efficient and produce more power than other SC kits on the market today.

    170mm Throttle Body w/ 123mm CAI. This Black Satin Crusher 2.9L Whipple Kit comes with a large 170mm mono blade throttle body that is complemented perfectly by the included 123mm cold air intake kit designed for a slot style MAF (sold separately). The increased air volume of this W175ax Supercharger allows for massive low-range torque gains as well as increased HP and TQ across the board.

    Supercharger Kit. As a complete bolt-on system, this Crusher 20-21 psi Twin Screw Supercharger will require custom calibration for your PCM (not included). 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 Crusher 2.9L Whipple Supercharger Upgrade Kit is designed as a performance upgrade for the 2003 to 2004 SVT Cobra Mustangs.

    Technical Note. Engines with boost levels over 13 psi should always have the PCM recalibrated.

    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.

      Blown away

      Blown away! Great Supercharger! Only down side is the wait time for Whipple to build the kit, and get it out to you. It's capable of plenty of boost/power. 900 hp to the tire, with the right mods is easy for this blower to do. Install is straight forward for anyone who knows their way around these cars, although I recommend a good tuner on hand after the install.

    • The Whipple Crusher W175AX 2.9L Supercharger Upgrade Kit horsepower gain depends on what other modifications you have done to the car as well as what tune you are running. As far as upgrading more parts, it depends on how much boost you are looking to run.

    I am looking to supercharge my 99 Cobra with an end result of 500rwhp (or more). Would the other 2.9L make that power or would I be better off going with this "crusher" supercharger? I already have the other supporting mods and build requirements on the list 1 answer
