Golf cart manufacturers typically limit the amount of speed that their carts can achieve due to restrictions placed on them by golf courses (usually 12 m.p.h. limit). What if you would like to give your golf cart a little extra pep though? Obviously, the best way to supe up your golf cart would be to install a more powerful engine in it. If this is not an option, however, you may want to explore ways to increase the power of your current golf cart engine.
Step 1: Find Engine
The first step in this process will be to actually find the golf cart engine so that you will be able to work on it. Typically, there will be a panel behind the seat of your golf cart that can be removed using a screwdriver.
Step 2: Find Governor
The governor in your golf cart engine is the part of the engine that is designed to limit the amount of power that the engine is capable of putting out. If you want to supercharge your golf cart, the governor is the part that you will need to adjust. There are several different types of governors in golf cart engines, depending on the manufacturer, but by far the most common is the spring-loaded model. You will typically find this type of mechanical governor in line with the cart’s accelerator module. More specifically, the spring-loaded type of governor will usually be at the carburetor or near the differential. Once you have located the spring-loaded governor, turn the device using a wrench in one direction or the other. You will need to test the cart to determine which way the spring will need to be turned to produce higher speeds. Once you have determined the direction, turn the governor in that direction until the desired speed increase is achieved.
Step 3: Adjust Clutch/Throttle Cable
Another type of governor is the clutch/throttle cable. You will find this type of governor next to the secondary sheave or driven clutch. To adjust this type of governor, use a wrench to adjust the tension on the throttle cable. Lengthening this cable will provide more power to your engine, as more gas will be able to enter the engine.
Step 4: Spark Regulation Type of Governor
The final type of governor that your golf cart may feature is electrical, as opposed to manual, and may therefore be beyond your ability to regulate manually. This type of governor was developed specifically to prevent do-it-yourselfers from fiddling with the power output of their golf cart engines. Rather than adjusting the amount of fuel that is fed into the engine, this type of governor regulates power output by limiting the amount of sparks igniting the engine. This type of power regulator is often connected directly to the ignitor in the engine, and is therefore impossible to adjust without also tampering with the ignitor, which is not recommended. Unfortunately, if you have this type of golf cart power governor you may be out of luck when attempting to increase your speed.
