Show original supplier description
The ProCharger High Output Tuner Kit represents the ultimate power adder solution for your 1985-1991 Corvette C4 TPI (L98). This tuner kit is designed to bolt on and deliver substantial horsepower gains, offering 55-75%+ more HP on 93 octane fuel and 8-10+ psi of boost. The D-1 supercharger, featured in a satin finish, is at the core of this performance upgrade. This kit is specifically for competition use and is explicitly not intended for street use, nor is it legal for street use in California. It may also be illegal nationwide under the Federal Clean Air Act. Purchasing this product requires signing a Vehicle Compliance Waiver, acknowledging its racing-only nature. Customers will also note a WARNING regarding Cancer and Reproductive Harm. For 1985-1991 models, this kit utilizes a 2-core intercooler and factory 6-rib belt drive, complemented by a Bosch blow-off valve. Fuel components and tubing are provided. An optional 3-year supercharger warranty is available, in addition to the standard 1-year warranty. Tuner Kits are intended for stock engines where a ProCharger dealer will supply the fuel system and custom tuning.
