Construction & Design

This boost pulley is meticulously CNC machined from billet aluminum, ensuring exceptional strength and precision tolerances. The billet construction resists deformation under high RPM and torque loads, maintaining consistent boost levels and reliability during demanding driving conditions. The black electrophoretic coating not only enhances corrosion resistance but also delivers a smooth, uniform finish that protects the pulley from environmental wear and tear.

The 5-rib serpentine design matches factory specifications, allowing for direct replacement without requiring belt or accessory modifications. This ensures a clean installation that preserves the integrity of your vehicle’s accessory drive system.

Performance & Sound

By reducing the pulley diameter to 3.20 inches, this upgrade increases the rotational speed of the supercharger, resulting in an estimated 1 to 2 pounds of additional boost pressure. This boost gain translates to improved throttle response, increased horsepower potential, and enhanced overall engine performance. Actual gains will vary based on your vehicle’s engine size, supporting modifications, and tuning.

While the pulley itself does not directly affect exhaust sound, the increased power delivery contributes to a more aggressive engine character and driving experience. Professional installation and ECU tuning are recommended to maximize performance and maintain engine reliability.

Installation & Fitment

The CFR Performance Hellcat Boost Pulley is designed for direct fitment on 5-rib serpentine belt systems found in select Dodge Challenger, Charger, and Durango models equipped with the 6.2L Hellcat engine from 2000 through 2026. Installation requires removal of the factory supercharger pulley and replacement with this upgraded unit.

This pulley is compatible specifically with the Metco Motorsports Hellcat Supercharger Pulley Hub and is not compatible with the ZPE Inc. Griptec hub. Due to the nature of boost increases, professional installation and tuning are strongly recommended to ensure optimal performance and engine safety.
