I have a need for speed!    

The standard speed of a golf cart today is 12 to 14 miles per hour but many options are available to increase both the speed and power should you desire.

Gas golf cart:

Simply adjusting or removing the governor system on a gas cart is asking for trouble. The engine design RPM should not be exceeded and your golf cart professional can adjust these systems to the high end of the acceptable RPM.
Changing the differential gear ratio is a great way to gain additional speed but you will loose low end torque for hill climbing so there is a trade off. Speeds of up to 25 MPH are attainable with the right combination of gear ratio, tire size and engine adjustments.

Electric golf cart:

A large assortment of optional motors, controllers and tires can make your electric golf cart a powerful and fast vehicle. These changes must be designed as a system where wire size, controller capacity and motor amp draw are all taken into consideration. Even the forward and reverse switch may require an upgrade to handle the increased power.

The club car IQ cart has some factory adjustment upgrades available which is the most cost effective way to attain speeds approaching 20 MPH.

Discuss your requirements with your golf cart professional and he can suggest a power package to give you what you are looking for.
