The BWoody V3 Anti-Slip Idler Pulley is designed to increase supercharger belt wrap and help eliminate belt slip on modified 6.2L Supercharged Gen 3 HEMI applications. Compatible with the Dodge Charger Hellcat, Challenger Hellcat, Jeep Grand Cherokee Trackhawk, and Demon applications using smaller pulleys, the V3 system adds approximately one additional inch of supercharger pulley wrap to help maintain belt engagement under load. Each kit combines a BWoody Performance V3 adjustable idler bracket with a Metco billet aluminum idler pulley, necessary installation hardware, and detailed instructions. Pulley options include 3-inch and 3.5-inch billet aluminum configurations, allowing the system to be matched more closely to the vehicle’s supercharger pulley setup. Finished in anodized black and engraved with the BWP logo, the V3 also adds a clean performance appearance to the engine bay while addressing an important issue found in higher-output supercharged HEMI combinations.

Supercharger belt slip can become a concern as a Hellcat-based combination moves beyond its original pulley configuration. Smaller supercharger pulleys increase the demand placed on the belt drive, and insufficient belt contact around the pulley can reduce the system’s ability to maintain consistent engagement. Instead of adding horsepower directly, the BWoody Anti-Slip Idler is designed to help the existing supercharger drive operate more effectively by increasing belt wrap around the pulley.

BWoody accomplishes this by positioning an additional idler to provide approximately one inch of extra belt wrap around the supercharger pulley. Increasing the amount of belt contacting the pulley gives the drive system additional engagement where it is needed. This makes the V3 especially useful for modified Hellcat, Redeye, Demon, and Trackhawk combinations where smaller pulley configurations and increased supercharger speed can make belt management more important.

The V3 system is also fully adjustable, giving installers additional flexibility when setting up the belt drive. BWoody offers the kit with either a 3-inch or 3.5-inch Metco billet aluminum idler pulley. The manufacturer specifically recommends the larger 3.5-inch pulley for combinations running 2.40 and 2.50 pulley configurations. Selecting the appropriate idler size allows the system to better complement the rest of the supercharger drive combination.

Installation does require consideration of belt length. BWoody states that the V3 typically requires a belt approximately 1/2 inch to 1 inch longer, depending on pulley size, and the replacement belt is not included with the kit. Belt length should therefore be confirmed for the exact upper pulley, lower pulley, idler, and tensioner configuration before installation.

Construction is equally performance-focused. The supplied billet aluminum idler pulleys are manufactured by Metco Motorsports, while BWoody supplies its V3 bracket, hardware, and installation instructions. The black anodized finish and engraved BWP logo give the assembly a finished appearance that complements modified Hellcat engine bays.

For supercharged Gen 3 HEMI owners pushing beyond the factory pulley combination, the BWoody V3 Anti-Slip Idler Pulley provides a practical way to improve belt wrap, reduce the potential for slippage, and support a properly configured high-performance supercharger drive system.
