Vortech's "Power Cooler" aftercooler kit uses a water-to-air heat exchanger to reduce intake air temperature from the supercharger. Reduced intake temperature lets you run more boost and ignition timing without detonation. Power gains range from 10 all the way up to 70 horsepower depending on engine configuration and boost level.
Kits come complete with a water reservoir, circulation pump, hoses and all support hardware and plumbing. They're even 50 state smog legal and maintain Vortech's full warranty coverage! The battery must be relocated to the rear of the vehicle to fit the Power Cooler. But hey, you wanted to do that anyway for better traction and handling, right!
