What is the main benefit of a larger diameter supercharger pulley?

A larger diameter pulley changes the drive ratio between the engine and the supercharger. This can result in the supercharger spinning at a different speed relative to engine RPM, potentially affecting boost levels and power delivery.

Can this pulley be used with any supercharger belt?

This pulley is designed with both 10-groove and 7-groove belt configurations. You will need to select the appropriate belt length and type that matches the groove you intend to use on your supercharger system.

What material is this pulley made from?

The product information indicates this is a well-built pulley with solid construction, suitable for performance applications. Specific material details beyond this are not provided.

By changing the pulley ratio, you can adjust the speed at which the supercharger spins relative to the engine's RPM. This ATI pulley is well-built with solid construction, intended to handle the demands of a performance application. The dual-groove design means it can adapt to different belt configurations, which is a practical consideration if you've modified your setup or are planning to.

This pulley is a direct replacement part for the specified Viper models. Ensure you have the correct belt length for your chosen groove configuration to maintain proper tension and alignment.
