2.9L Direct Drive Twin-Screw Supercharger

The Whipple W175AX 2.9L Direct Drive Twin-Screw Supercharger is engineered for custom applications and as a replacement for existing Whipple compressor assemblies. Built upon Whipple's long-standing expertise in twin-screw supercharger technology, this unit is proudly designed, manufactured, and assembled in Fresno, California. OEM manufacturers utilize positive displacement superchargers for their instant boost response and broad power delivery across the RPM range. The twin-screw design of the W175AX specifically excels at providing robust low-end torque and significant peak horsepower potential, with efficient airflow suitable for both low and high-boost scenarios. This supercharger head unit features a 2.9L displacement and a direct-drive configuration. A key benefit is the extended 100,000-mile oil change interval, minimizing maintenance downtime. The W175AX is available in either a black or polished finish to suit aesthetic preferences. Specifications for the W175AX 2.9L Direct Drive include a maximum continuous and peak RPM of 18,000, a maximum CFM of 1,720, and a maximum boost pressure of 30 PSI. It boasts a peak volumetric efficiency of 99% and a peak adiabatic efficiency of 78%. The compressor oil capacity is 5.4 fl/oz, with the extended oil change intervals contributing to its long-term reliability.
