Common Modifications To Increase The Top Speed Of a Predator 670cc Golf Cart

Just installing a predator 670cc engine on a golf cart may not be able to give you the desired speed. You may need some additional modifications to achieve that. Let’s check some of them out!

Increase the tire size 

An effective way of increasing the speed of a predator 670cc golf cart is to install larger tires. Larger tires cover more areas as the golf cart runs that can help increase speed. 

Change gear ratio 

Gear ratio has a big impact on the speed and acceleration of a vehicle. You can change the gear ratio by getting new gears for your golf cart. 

This job requires good mechanical skills. It may be wise to discuss with an expert in this field while both selecting and changing the gears.

Calibrate the air intake and exhaust system 

The perfect airflow, both in and out, is crucial for a vehicle’s engine health. It’s not any different for a golf cart. 

You can try calibrating both the air intake and exhaust system of your golf cart to improve the top speed. Getting a good performance air filter can help so much in this case. 

Get a more suitable carburetor  

Another great and effective way of improving the top speed of a Predator 670cc golf cart is to get a performance carburetor. You can also fine-tune the existing carburetor, if possible.

While at it, you can also get new spark plugs. Some golf cart users experienced in this sector shared that replacing the spark plugs with new ones helped with the performance of the cart.

Adjust the speed governor 

Usually, golf carts are not built for speed driving. Many golf carts come with a speed governor or limiter to keep the speed in check.

If you want to increase the top speed, adjusting the governor may help. Some users explained that removing the contraption helped with their cart’s speed. Contraptions include throttle cable and governor. 

Note: It must be done with caution. You can’t let this modification affect the stability of the cart.
