Hellcat Throttle Body Porting

The F.A.S. Motorsports Hellcat Throttle Body Porting service is a precision CNC porting upgrade for the factory throttle body found on Hellcat platform vehicles, including the Dodge Challenger, Charger, Durango, and RAM TRX. The factory Hellcat throttle body, while designed for high-performance use, features casting restrictions and bore transitions that reduce peak airflow when the engine demands maximum intake volume. The F.A.S. Motorsports porting service removes these restrictions through precision machining of the bore inlet, blade bore, and port transitions to maximize the throttle body's effective airflow capacity. The result is improved throttle response, more immediate boost buildup, and enhanced high-RPM power delivery — all without requiring a larger aftermarket throttle body. This service is particularly valuable for builds that have already increased boost pressure through a pulley upgrade or supercharger replacement, where the factory throttle body's flow restriction becomes a limiting factor. Customers have two options: send in your existing OEM throttle body for porting and return, or take advantage of the FAS CORE Exchange Program where you receive a pre-ported unit immediately and ship your OEM unit back afterward. Both options deliver the same precision-machined results. This service pairs seamlessly with the FAS 130mm billet supercharger snout upgrade for a fully optimized inlet system on Hellcat platform builds.
