FAS 4.5L Whipple Supercharger Race Porting Service

The F.A.S. Motorsports 4.5L Whipple Supercharger Race Porting Service is a professional-grade performance service designed to unlock the full potential of the Whipple 4.5L twin-screw supercharger. The 4.5L Whipple is one of the most popular high-performance superchargers on the market, used extensively in Hellcat, RAM TRX, and other high-horsepower applications, and while it offers impressive out-of-the-box performance, there is still significant restriction at the inlet and discharge ports that limits peak airflow — especially at high boost levels and RPM. The F.A.S. Motorsports porting service uses precision CNC machining to open up the inlet opening, smooth the port transitions, and optimize the flow path through the supercharger body. The improvements reduce inlet restriction, improve rotor efficiency, and lower the parasitic load on the supercharger at full boost — resulting in more net power at the wheels. Customers who have had their 4.5L Whipple ported by F.A.S. Motorsports report improved boost response, more consistent power delivery, and measurable dyno gains over a stock 4.5L unit. This is a send-in service — you ship your Whipple supercharger to F.A.S. Motorsports, where skilled technicians perform the porting to exacting specifications and return the unit ready for reinstallation. This service is an excellent complement to pulley upgrades, larger throttle bodies, and full race builds where maximum airflow is the priority.
