The all-new system features Whipple’s massive oversized air-to-water intercooler for unmatched cooling capacity, W175FFax Gen 3 Whipple twin-screw supercharger that reaches 99% volumetric efficiency and industry leading power potential. The unique intercooled bypass system offers better acceleration and less than 1hp of consumption during cruising for excellent fuel economy. The system also includes a massive (over 3 times larger than competition) intercooler water reservoir that has over 4 gallons of capacity, aluminum high flow intake manifold and HP Tuners for the factory ECU and transmission recalibration. While others claim, Whipple Superchargers simply deliver more power per pound of boost than any other supercharger on the market today.
