Tuner Kits and Supercharger Options

Tuner kits are the same as complete systems except without the fuel system upgrades or ECM reprogramming. This allows for custom tuning and fuel modifications that the custom tuner or racer may prefer. Vortech has supercharger options for various types of racing or boost level. For continued use, such as road racing, the V-2 series superchargers share the engine's oiling system. This approach is more suitable for continued boost conditions and allows for the addition of an oil cooler or filter.
