CFR Performance Hellcat Supercharger Boost Pulley

2000–2026 Dodge Challenger, Charger, Durango 6.2L Hellcat

Part #: HZ-7250-PBK

Overview

The CFR Performance Hellcat Supercharger Boost Pulley 2.50" is a precision-engineered upgrade designed to increase the supercharger boost pressure on your 6.2L Hellcat engine. Compatible with Dodge Challenger, Charger, and Durango models from 2000 through 2026, this pulley offers a straightforward bolt-on solution to unlock additional horsepower and torque. Ideal for enthusiasts seeking enhanced acceleration and throttle response, it integrates seamlessly with factory 5-rib serpentine belt systems and select aftermarket components.

By increasing boost pressure by approximately 6.5 to 8 pounds, this pulley delivers noticeable performance gains without requiring extensive modifications. It is recommended to pair this upgrade with professional ECU tuning to maximize power output and maintain engine reliability.

Key Features

Engineered for durability and performance, the CFR Performance Hellcat Supercharger Boost Pulley offers the following key features:

• 2.50" (63.50mm) pulley diameter designed to increase supercharger rotational speed and boost pressure
• Estimated boost gain of 6.5 to 8 pounds, depending on engine setup and supporting modifications
• Compatible with 6.2L Hellcat engines in Dodge Challenger, Charger, and Durango models from 2000 to 2026
• CNC machined billet aluminum construction for superior strength and precision
• Durable black electrophoretic coating (e-coating) for corrosion resistance and a sleek finish
• Designed for factory 5-rib serpentine belt systems to maintain OEM belt alignment and accessory drive function
• Works exclusively with Metco Motorsports Hellcat Supercharger Pulley Hubs (not compatible with ZPE Inc. Griptec hubs)
• Direct bolt-on installation with no permanent modifications required

Construction & Design

This boost pulley is meticulously CNC machined from high-strength billet aluminum, ensuring exceptional durability and dimensional accuracy. The billet construction resists deformation under high rotational forces, maintaining consistent boost levels and belt alignment during demanding driving conditions. The black electrophoretic coating enhances corrosion resistance and provides a smooth, uniform finish that withstands harsh engine bay environments without chipping or wear.

The pulley’s 5-rib serpentine design matches factory belt profiles, allowing for seamless integration with the existing belt system. This ensures reliable accessory drive operation and preserves belt life while delivering increased supercharger speed.

Performance & Sound

By reducing the pulley diameter from stock size, the CFR Performance Hellcat Supercharger Boost Pulley increases the rotational speed of the supercharger, resulting in a significant boost pressure increase of approximately 6.5 to 8 pounds. This elevated boost directly translates into enhanced engine power and torque, improving acceleration and throttle response for a more engaging driving experience.

While the pulley itself does not alter exhaust sound, the increased performance may contribute to a more aggressive engine note under load due to higher combustion pressures.

Installation & Fitment

Installation is straightforward for experienced technicians and knowledgeable enthusiasts familiar with supercharger systems. This pulley is designed to fit factory 5-rib serpentine belt setups on 6.2L Hellcat engines found in Dodge Challenger, Charger, and Durango models from 2000 to 2026. It is compatible only with Metco Motorsports Hellcat Supercharger Pulley Hubs and is not compatible with ZPE Inc. Griptec hubs.

Professional installation and ECU tuning are strongly recommended to optimize performance gains and ensure engine safety and reliability.

What's Included

• 1 x CFR Performance Hellcat Supercharger Boost Pulley 2.50" (63.50mm)
