Whipple W140AX Bare Supercharger Head Unit 2.3L (Extended Drive) WSC-140AXB
High-Output Twin-Screw Head Unit for Custom Supercharger Systems
The Whipple W140AX 2.3L Bare Supercharger Head Unit is engineered for builders and performance shops developing their own supercharger systems for resale or custom applications. This is the WSC-140AXB head unit only, featuring the AX axial rear-entry design. The former radial (top-entry) version has been discontinued, making this the current and supported configuration.
OEM manufacturers rely on positive displacement twin-screw superchargers because they deliver instant throttle response, exceptional drivability, and a wide, usable powerband. The W140AX provides up to 80% adiabatic efficiency and up to 99.9% volumetric efficiency, allowing it to produce massive torque down low while maintaining strong top-end horsepower at higher boost levels.
Compared to centrifugal and turbo systems, the Whipple twin-screw design eliminates lag during throttle transitions and gear changes. Unlike roots-style superchargers, which lose efficiency as boost increases, the W140AX maintains excellent thermal and mechanical efficiency under demanding conditions. This makes it an ideal foundation for low-boost street systems or high-boost race builds.
Whipple offers screw compressors across a wide displacement range, along with multiple drive lengths, pulley configurations, and bypass valve options, allowing builders to tailor systems precisely to their application. The W140AX is available as a complete unit or rotor assembly for custom housings, giving fabricators maximum flexibility.
