2.4L Billet Supercharger Snout (Hellcat)

What Is the Hellcat Supercharger Snout?

The supercharger snout is the front housing of your IHI 2.4L positive-displacement blower — the section that holds the rotor pack in position and routes airflow from the throttle body into the supercharger inlet. The factory unit is cast aluminum. The FAS billet snout is precision-machined from billet aluminum stock for tighter tolerances, improved flow geometry, and greater structural integrity under sustained high-boost conditions.

If you are running a 2.4L Hellcat platform — naturally-aspirated-converted Challenger, base Hellcat, or any non-Redeye application — and want to maximize airflow into the supercharger without a full snout porting service, this is your starting point.

Why Billet Over Cast?

Cast snouts are adequate at stock power levels. As boost climbs — through smaller pulleys, more aggressive tune calibrations, or supporting mod stacks — cast housings become a limitation. Billet provides:

- Tighter dimensional tolerances — closer rotor-to-housing clearances for improved sealing efficiency - Improved surface finish — lower drag at the inlet passage, particularly noticeable at high supercharger speeds - Higher material strength — billet aluminum handles thermal cycling and sustained pressure better than cast equivalents

Is This Compatible With Hellcat Redeye and Demon Applications?

This snout is designed for 2.4L Hellcat applications. The Hellcat Redeye, SRT Demon, RAM TRX, and Trackhawk all use the 2.7L IHI supercharger — a different unit with a different snout geometry. This snout does not fit 2.7L blowers.

If you are on a 2.7L platform, contact FAS about snout porting on your existing 2.7L supercharger housing.

FAQ

Q: What is a hellcat supercharger snout? A: The supercharger snout is the front housing of the IHI blower — the section that positions the rotor pack and channels airflow from the throttle body into the supercharger inlet. The billet hellcat supercharger snout replaces the factory cast aluminum unit with a precision-machined billet version for tighter tolerances, improved flow geometry, and greater durability under sustained high-boost operation.

Q: Is the FAS billet snout compatible with Hellcat Redeye and Demon applications? A: This billet snout is designed specifically for the 2.4L Hellcat supercharger (non-Redeye applications: base Hellcat Challenger, Charger, Durango SRT, Jeep Grand Cherokee SRT). It is not compatible with the 2.7L IHI supercharger found in the Hellcat Redeye, SRT Demon, RAM TRX, and Trackhawk. If you are on a 2.7L platform, contact FAS to discuss snout porting options for your existing 2.7L housing.
