What is the benefit of an 8-rib belt design on this pulley?

An 8-rib belt design offers more surface area contact with the pulley compared to a standard 6-rib belt. This increased grip helps to prevent belt slippage, ensuring more consistent power transfer to the supercharger, especially under high load conditions.

How does a smaller diameter pulley affect supercharger performance?

A smaller diameter pulley, like this 95mm unit, forces the supercharger to spin faster for a given engine speed. This results in increased boost pressure being delivered to the engine, which can lead to a significant improvement in horsepower and torque.

Can this pulley be shipped to California?

No, this HKS pulley is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

This 95mm, 8-rib supercharger pulley from HKS is crafted from a solid aluminum alloy, chosen for its lightweight properties and ability to maintain its shape under stress. The 8-rib design is key here, offering a more robust grip than a standard 6-rib belt, which helps prevent slippage, especially when you're pushing your engine hard. This improved belt contact means more consistent boost delivery to your supercharger.

HKS is well-known for its performance parts, and this pulley is built to their standards. The precise sizing ensures it fits correctly onto compatible supercharger systems, allowing for a straightforward installation process for those familiar with forced induction setups. By using a smaller diameter pulley like this 95mm unit, you can increase the rotational speed of your supercharger, which in turn raises the boost pressure your engine receives. This can lead to a notable increase in horsepower and torque, giving your vehicle a more responsive feel.

Keep in mind that this pulley is not CARB approved and cannot be shipped to California. Always refer to your specific supercharger system's installation manual for detailed instructions and any additional components you might need.
