With the latest technology, this Whipple system makes more power than any other positive displacement supercharger system on the market giving you tire frying, neck whipping power that will give you a grin from ear to ear. The all-new system features Whipple’s massive oversized air-to-water intercooler for unmatched cooling capacity, W140ax 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 new Whipple system is 100% complete and is designed for stock engines but has enough capability to work with heavily modified engines. While others claim, Whipple Superchargers simply deliver more power per pound of boost than any other supercharger on the market today.

This system is 100% complete, including Whipple's 2.3L supercharger, high-flow fuel injectors, aluminum high flow intake manifold, SCT Flash Programmer for the factory ECU recalibration, and all the pre-formed & fitted hoses with all the necessary wiring connectors for a easy installation. The calibration is for stock vehicles or those with a catback only, just bolt on and drive.
