Vortech 1999 GT 4.6L V-3 Si-Trim Tuner Kit (Polished)

The 1999 Mustang GT comes from the factory with an impressive 260 horsepower and 302 ft/lbs of torque. A Vortech supercharging system can safely increase this to 364 horsepower and 371 ft/lbs of torque. You will be impressed by the seamless integration of the supercharger system and the true supercar performance it delivers.

This system features the all-new V-3 Si-Trim supercharger. The V-3 supercharger features an internally lubricated transmission, allowing for supercharger installation and operation without oil lines.


  • Helical gear design with 3.6:1 step-up
  • Includes remote fluid drain hose (attached to supercharger) that allows for simple fluid changes without removing the supercharger from the vehicle
  • A ventilated gear case assembly eliminates any potential internal pressure issues that are currently associated with non-vented competitive designs
  • Integrated gear case baffling for proper oil control
  • Simple oil slinger design does not require separate shaft or bearing set. This provides proper fluid delivery to gears and bearings
  • Superchargers are factory pre-filled with our special synthetic fluid.
  • Integrated dipstick for simple fluid checks

NOTE: Battery MUST be relocated to the trunk to run the V-3 Si-Trim Blower
