  10. Lethal Performance Gatekeeper Torque Pipe Upgrade for Paxton / Vortech Supercharged Mustangs (2015-2020 Mustang GT)
    $714.99

    Looking to gain more torque out of your 2015-2020 Paxton or Vortech supercharged mustang? The Lethal Performance Gatekeeper will do just that. Centrifugal supercharger setups build boost with rpm so horsepower and torque suffer a bit in the lower rpms. Our Gatekeeper setup will allow you to gain the missing horsepower and torque in the lower rpm's by spinning the supercharger harder but still allowing you to control the desired boost you want to run based on what spring that's used in the waste gate.

    This is a simple upgrade which includes all of the components needed for installation.

    What's Included:
    Turbosmart WG38 2011 Ultragate 38 in Blue (7psi Spring Standard)
    New Charge Pipe with CNC Machined Billet Aluminum Flange for Wastegate
    NPT Fitting for Flange
    12" of Vacuum Hose
    Wastegage Spring of your choice
    New Vortech / Paxton Supercharger Pulley (Griptech Optional)

    Note: No timing changes are required as long as you keep boost at the level you're currently tuned for. However is recommended for you tuner to lower initial timing due to the increased torque the car will make with this setup.
    Mbr>Our Gatekeeper setup includes a 6 or 8 rib 3.33" Paxton / Vortech pulley with the option for a Griptec one. The stock 103" belt will work by moving the idler in, but the recommended belt length is 100". Belt options are listed in the dropdown menu option.
