This kit boosts horsepower from 260 to as much as 402, not to mention upping the torque level. The quality components include a maintenance-free V-3 Si-Trim compressor and an integrated air-to-water charge cooler.

      Gear Driven Supercharger. This Vortech Complete Kit contains everything for the upgrade. You get the gear-driven supercharger, the fully integrated after cooler for charge cooling, high-flow bypass valve, and very efficient impeller, all made using the newest technologies. An advanced housing design is maintenance-free and both oil feed and oil drain units provide superior lubrication. Fuel maintenance upgrade parts come in this kit, too. A polished finish gleams for a quality appearance, and SQ technology provides a nearly silent compressor activity.

      Professional to Install. Given the intricacy of this Vortech V-3 Si-Trim with Charge Cooler Kit, we recommend that a professional install it. The process takes about 12 hours, including mounting it with the included sturdy, factory-style mounting bracket. All required hardware and parts come in the kit.

      Warranty Included. Vortech warranties this Polished Supercharger Cooler Kit for 3 years, with some limitations. For full details, please read the manufacturer's warranty.

      NOTE. The system is not CARB legal.

      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.
