Construction & Design

The aFe Supercharger Power Pulley Kit is meticulously crafted from premium 6061-T6 billet aluminum, known for its excellent strength-to-weight ratio. This material choice ensures the pulley is both lightweight and robust, reducing rotational mass and improving throttle response. The black hard anodized finish not only enhances corrosion resistance but also provides a durable, attractive surface that withstands the rigors of high-performance use.

The hub is precision CNC machined from 17-4 stainless steel, a material prized for its high strength and resistance to corrosion. This combination of materials and manufacturing processes guarantees a perfect fit, exceptional durability, and a professional finish that complements the Hellcat’s engine bay.

Performance & Sound

By reducing the diameter of the supercharger pulley to 2.50 inches, this kit increases the supercharger’s rotational speed, resulting in an approximate 6 PSI boost increase. This translates to improved engine power and throttle response, enhancing overall driving dynamics. While the primary focus is on performance gains, users may also notice a subtle change in supercharger whine, adding to the aggressive character of the Hellcat’s sound profile.

Installation & Fitment

Installation of the aFe Supercharger Power Pulley Kit requires removal of the factory pulley from the supercharger snout, which involves special tools and technical expertise. Due to the precision nature of the components and the need for proper belt sizing, professional installation is highly recommended to ensure optimal performance and reliability.

Additionally, the kit requires the use of a smaller belt (Gates K100570HD) to accommodate the reduced pulley diameter. Proper tuning is also necessary after installation to safely maximize the increased boost and maintain engine reliability.
