Torque, or more accurately end torque in our use of the word, is the turning power of your wheels moving your golf cart.

Adding More Torque

Torque can play a big part when it comes to adding speed to your golf cart. The more torque your golf cart has, the more speed it can produce.

Upgrading The Motor

The first thing you should look for in a motor for your golf cart is the size of the field coil. Typically, Series Wound Torque Motors have larger coils inside. The larger coil allows for a larger magnetic field generation. This can hold the armature much more securely, which in turn creates more torque.

Upgrade The Speed Controller

Besides your motor, there are several parts to your golf cart that can increase the overall speed that you need to consider before throwing a new motor in.

Upgrade Your Battery

Installing a new battery with a higher voltage is a quick and easy way to increase your overall power and speed for your golf cart. Changing the battery on your golf cart takes little to no time at all, and can be the difference in maximizing your golf carts speed.

Upgrade to Bigger Tires

Increasing your tire size is probably the easiest and most cost effective way to get more speed out of your golf cart. The nice thing about upgrading your tire size, is that it doesn’t matter whether you have a gas or an electric cart.

Keep Your Golf Cart Clean

I know it seems silly to think that keeping a golf cart clean would add some speed, but you’d be surprised. Obviously a nice and shiny outside can cut down a little bit on aerodynamics, but we’re mostly talking about the junk you rarely notice on the undercarriage.

Final Thoughts

Making your golf cart faster can be done in a variety of ways, and over an extended period of time.

Expectations and Cautions

You should have reasonable expectations when trying to speed up your gas golf cart. The average speed of a golf cart is 12- 14 MPH, so if you think you can transform your cart into a vehicle that can merge onto the freeway, think again. However, gaining up to 10 MPH is certainly within reach.

1. Remove the Governor

The governor limits the top speed your golf cart can move. Removing the governor on your gas golf cart is a bit of a risky option, but it certainly gives you what you want: more speed.

2. Upgrade the Engine

All of the main golf cart manufacturers (E-Z-Go, Club Car, and Yamaha) have stock engines in their gas models which are high quality and efficient. Upgrading your engine, however, is a great way to gain speed without performing a riskier alternative such as removing the governor.

3. Upgrade the Speed Controller

The speed controller on your gas golf cart controls your acceleration, deceleration, and the speed at which your cart moves. So, an upgrade to your speed controller could certainly help make your golf cart faster.

4. Regular Maintenance

Golf cart maintenance is often overlooked, but it can be a key to your gas cart operating effectively. That includes how fast the cart moves.

5. Lose Weight

It might sound elementary, but reducing the weight of things like your golf bag and all of the extras that you carry in your golf cart will actually increase how fast your cart moves around the course.

Important Notes

If you intend to perform any changes to your golf cart it’s important to consult your owner’s manual and manufacturer warranty. Performing some of these repairs or upgrades yourself, instead of using a certified golf cart mechanic, can void your warranty.
