Whipple W175AX Bare Supercharger Head Unit 2.9L (Extended Drive) WSC-175AXB
High-Capacity Twin-Screw Head Unit for Custom Power Builds
The Whipple W175AX 2.9L Bare Supercharger Head Unit is designed for builders, fabricators, and performance shops developing custom supercharger systems or resale kits that demand maximum airflow, instant throttle response, and unmatched efficiency. This listing is for the supercharger head unit only, making it the ideal foundation for engineered, application-specific forced-induction setups.
OEM manufacturers choose positive displacement twin-screw superchargers because they deliver a wide, flat torque curve and immediate boost responsecharacteristics that centrifugal and turbo systems simply cannot match without lag. The W175AX offers up to 80% adiabatic efficiency and up to 99.9% volumetric efficiency, allowing it to produce massive low-end torque while maintaining strong top-end horsepower at higher boost levels.
Unlike roots-style superchargers, which suffer from poor efficiency as boost increases, the Whipple twin-screw design maintains superior thermal efficiency and reduced parasitic loss across the entire operating range. This makes the W175AX an excellent choice for low-boost street applications, high-boost race engines, and everything in between.
Whipple supports an extensive ecosystem of drive lengths, pulley configurations, and bypass valve options, giving builders complete flexibility to tailor airflow and boost characteristics to their specific application. The W175AX is available as a complete unit or rotor assembly for custom housings, offering unmatched adaptability in the performance market.
