Golf carts are becoming commonplace as cheap transportation around large properties or small communities. However, the dilemma of reaching a higher top speed plagues many a lead-footed cart driver. Without embarking on a complete golf cart overhaul, there are a few tricks that can make it go faster.
Instructions
1. Add larger tires. The bigger the tire, the larger the revolution and faster flat ground speed (provided the RPMs remain constant). Expect some loss of low-end torque.
2. Install a higher RPM high-speed electric motor. Take measurements to ensure a new, larger motor fits into the available chassis. Higher RPM motors might require that a higher amperage, high performance controller also be installed.
3. Remove or adjust the governor. Many golf carts have some kind of governor that limits the vehicle's top speed. The most common governors are located in line with the accelerator cable, a clutch activator cable or installed as an RPM or REV limiter.
4. Replace the existing gear sets with a gear set that has a lower ratio. The standard factory gear set ratio on golf carts is 12.5:1 and provides for a speed of roughly 14 mph. An 8:1 gear set ratio increases top speed to roughly 20 mph, but at the loss of low-end start up torque.
