Which drive options are used for some superchargers depending on the application?

• A. Multi-rib drive
• B. Gilmer drive
• C. Both multi-rib and Gilmer drive
• D. Timing belt

Answer: (C)

The drive choice for a supercharger depends on how the system balances torque, speed, and alignment in a given design. A multi-rib belt provides broad contact with the pulley, offering strong grip, smooth operation, and good tolerance to slight misalignment—making it a practical, compact option in many engine layouts. A Gilmer drive, using a toothed belt and matching pulleys, delivers a positive, slip-free connection that keeps the drive ratio exact at high speeds and under high torque, which is desirable in performance-focused or specialty setups. Because engineers tailor the drive to the specific application's needs—space, load, and reliability requirements—some superchargers use a multi-rib drive and others use a Gilmer drive. The idea is that both can be used depending on the design goals, not that only one universal option fits all situations.
