Product Details▾

The FAS Motorsports 4.5L Whipple Supercharger Race Porting Service is designed for racers and performance enthusiasts who demand maximum airflow and efficiency from their Whipple unit.


Our precision porting and hand-finishing process opens up airflow paths, reduces turbulence, and increases horsepower across the RPM range. This service is ideal for high-boost applications and race builds where every CFM matters.

We carefully port and smooth the inlet, throttle body opening, and critical airflow areas within the 4.5L Whipple housing. The result is stronger mid-range torque, improved peak horsepower, and optimized performance under extreme conditions.
