2.3L Bare Supercharger Head Unit

The Whipple W140AX 2.3L Bare Supercharger Head Unit is engineered for custom system builders who require a flexible, high-performance component for unique forced-induction applications. This unit is the WSC-140AXB, a 2.3L supercharger in the AX axial rear-entry configuration, as the older radial top-entry version has been discontinued. This bare head unit utilizes Whipple's proven twin-screw technology, which is celebrated for its instant throttle response, broad torque delivery, and strong power potential across the entire RPM range. Unlike centrifugal or turbocharger systems that rely on RPM or exhaust energy, Whipple's screw compressor provides immediate airflow as soon as the throttle is opened. This design is suitable for both low-boost and high-boost custom applications, provided the complete system is properly engineered and matched. Builders must verify all critical application requirements before ordering, including compressor sizing, drive length, pulley configuration, inlet and outlet designs, bypass valve layout, lubrication needs, mounting configuration, belt alignment, cooling strategy, fuel system requirements, and necessary calibration. The W140AX platform is built for durability and dependable performance, making it a versatile choice for custom vehicle, marine, industrial, and specialty projects. Whipple Superchargers has been a leader in twin-screw technology since 1987, with all components designed, manufactured, and assembled at their facility in Fresno, California.
