What is the main advantage of a 10-rib belt system?

A 10-rib belt system is designed to handle higher torque loads than a standard 6-rib belt. This increased grip helps prevent belt slippage, especially under heavy boost conditions, ensuring consistent power delivery.

What does the 74mm diameter signify?

The 74mm diameter refers to the size of the pulley. This specific size is chosen by tuners to achieve a particular boost level when paired with the correct supercharger and engine combination.
