When one thinks of a Hellcat-powered Challenger or Charger, few are thinking, “Man, these are really restricted by the factory” but you’d be surprised. There’s quite a bit of unlocked potential within these big-power-producing powerplants and Edelbrock just announced a quick way to let that blown semi-hemispherical V8 breathe a little bit easier.
Their new BIG MOUTH Hellcat Supercharger Nose Drive (pt# 15462) is engineered specifically for 2.4L Hellcat superchargers used in “2015–2023 Dodge Challenger Hellcat models. Designed, cast, and machined entirely in the USA, this latest innovation delivers increased airflow, boost, and power.” Yes, you read that right: 100-percent USA-made casting and engineered.
Then consider that this is a direct “bolt-in” replacement for the factory Hellcat 2.4L nose drive that accommodates throttle bodies ranging from stock 97mm (when using the included adapter) to 130mm, and you’ve got true bolt-on performance that also solves the several weaknesses found in ported factory nose drives. A large 300M input shaft provides extreme strength under high-boost loads, and increases airflow.
Here’s the original press release:
Edelbrock is proud to announce the launch of the all-new BIG MOUTH Hellcat Supercharger Nose Drive, engineered specifically for 2.4 L Hellcat superchargers found in 2015–2023 Dodge Challenger Hellcat models. Designed, cast, and machined entirely in the USA, this latest innovation delivers increased airflow, boost, and power.
Developed by Edelbrock’s supercharger engineering team and produced at the company’s foundry in San Jacinto, California, the BIG MOUTH was refined with advanced Computational Fluid Dynamics (CFD) analysis to maximize efficiency. The result is a nose drive that reduces inlet restriction and unlocks the full performance potential of the Hellcat’s factory supercharger.
The BIG MOUTH is a bolt-in replacement for the factory Hellcat Nose Drive and is designed to work with a wide range of throttle bodies. With the supplied adapter plate, it accommodates the stock 97 mm throttle body, while also supporting the 105 mm Demon D170, aftermarket 108 mm units, and even massive 130 mm throttle bodies. Unlike heavily ported stock nose drives, the BIG MOUTH’s heavy-duty casting eliminates weak points, providing unmatched durability.
Built for serious strength, the BIG MOUTH features a 300M input shaft and a steel pulley hub for simple pulley ratio changes. Combined with its larger, optimized design, this nose drive delivers stronger, faster, and better performance for Hellcat enthusiasts who demand the best.
