W140AX 2.3L Twin-Screw Supercharger System

The Whipple W140AX 2.3L supercharger kit represents over 23 years of GM twin-screw supercharging experience, engineered to be the most powerful intercooled twin-screw SC system available for Chevrolet, GMC, Hummer, and Cadillac trucks and SUVs equipped with the 6.0L engine. This system provides tire-frying, neck-whipping power, offering a substantial increase in performance for a wide range of applications, from stock to heavily modified engines. At the heart of this system is the W140AX Whipple twin-screw supercharger, achieving 99% volumetric efficiency and industry-leading power potential. It is paired with a massive oversized air-to-water aluminum bar-plate intercooler, ensuring unmatched cooling capacity and delivering more power per pound of boost than competing superchargers. The unique intercooled bypass system contributes to better acceleration and maintains excellent fuel economy during cruising with less than 1hp of consumption. This comprehensive kit includes all necessary components for installation, such as high-flow fuel injectors, an aluminum high-flow intake manifold, and a Superchips Flash Programmer for factory ECU recalibration. Whipple emphasizes exclusive features like its 3x5 rotor combo for increased airflow, an oversized heat exchanger for optimal intercooler water temperatures, and a self-contained lubrication system. The design allows for quick pulley changes and OEM quick-connect fittings for ease of installation, with a completed installation that looks factory-installed. It is noted that this system is not legal for sale or use in California.
