Audi Eaton Supercharger Porting

The F.A.S. Motorsports Audi Eaton Supercharger Porting service is a precision-machined performance upgrade for the Eaton-style supercharger found on Audi's 3.0T TFSI engines, including models like the A6, A7, A8, S4, S5, and Q5. The factory Eaton supercharger features a twin-screw design that, while effective, contains significant casting restrictions in the inlet, discharge port, and rotor housing transitions that limit peak airflow and efficiency at higher RPM. The F.A.S. Motorsports porting service removes these restrictions through CNC machining of the inlet bore, port entries, and rotor housing transitions, dramatically improving the flow characteristics of the supercharger. The result is a measurable increase in boost response and delivered airflow, translating into improved mid-range torque, stronger top-end power, and reduced heat generation under load — all from the factory supercharger you already have. This is a send-in service — you ship your supercharger to F.A.S. Motorsports, where expert technicians perform the porting work and return the unit fully machined and ready to reinstall. The service is compatible with both naturally aspirated and modified 3.0T builds and pairs especially well with tune upgrades, pulley kits, and intercooler upgrades. For Audi enthusiasts looking to push their 3.0T platform further without a full supercharger replacement, the FAS Eaton Porting service is one of the most cost-effective performance upgrades available.
