W140AX Twin-Screw Supercharger Technology
At the core of the system is Whipples W140AX 2.3L twin-screw supercharger, engineered for up to 99% volumetric efficiency. Unlike roots-style blowers, Whipples twin-screw design compresses air internally, producing cooler, denser charge air with reduced parasitic loss.
The W140AX delivers instant boost from idle, making it ideal for heavy-duty trucks that demand immediate torque for towing, hauling, and daily use.
Massive Air-to-Water Intercooling
This system features a large air-to-water intercooler designed specifically for the GM 6.0L platform. Lower intake air temperatures support safer ignition timing, consistent power delivery, and improved reliability under sustained load conditions such as towing or work use.
Complete Bolt-On Hardware Package
The Whipple W140AX system is engineered as a complete hardware-only supercharger kit. All major components required for installation are included, providing a clean OEM-style fit with no internal engine modifications required.
