Bolt On 185 Horsepower

Bolt on a ProCharger D-1 supercharger kit, complete with V mount air to air intercooler and get ready for 185 hp more of tire screeching fun from your new Corvette while still running on high octane pump gas. ProCharger's HO Intercooled kit includes everything you will need for a professional, OEM quality installation. The kit includes a ProCharger self contained supercharger, mounting brackets, air to air intercooler, bypass valve system, piping, connectors, FMU, hoses, and all hardware. This kit can be installed by most back yard mechanics, with basic hand tools. Most ProCharger supercharger owners are up and running on the first day. Some cars, equipped with certain GM suspension options will require slight modification to hood reinforcement or supercharger bracket.

Corvette Supercharger Technology

Thanks to ProCharger's industry leading D-1 compressor design, ProCharger produces more power with less boost than the competition. The 6 rib direct drive and unrestricted air intake system also help increase the efficiency of the supercharger. L98 Owners with unmodified Corvettes can expect around 370 rear wheel horsepower. These gains are a product of ProCharger's commitment to having the industries lowest charge air temperatures. That, in conjunction with their reputation for quality, reliability, and street driveability is why a ProCharger Supercharger is the ultimate power adder.

Integrated System Design

Unlike its competition, ProCharger locates both the intercooler and supercharger away from the high-heat, detonation causing areas of the engine. The C4 kit was designed to minimize factory component relocation and requires little or no modification of stock Corvette parts.

D-1

This kit includes Procharger's D-1 Supercharger, capable of making over 370 rear wheel horsepower and is capable of making even more with additional L98 modifications or with more boost. Their supercharger features 6061 Billet Aluminum housings with CNC machined casings for precise alignment. Inside, ProCarger's D-1 incorporates industry leading innovations such as a 4.44:1 step up ratio, aerospace quality high speed bearings, and a 7075 T-6 Billet Impeller. The D-1 is a great match for a C4 L98 owner, who would like to produce 350-500 rear wheel horsepower, with immediate low end pull.
