EZGO TXT is a popular choice among golf cart enthusiasts for its versatility, reliability, and affordability. The standard model, however, may not always provide the desired top speed for those who seek a little more excitement on the course. To address this, we will explore various methods for upgrading the speed of your EZGO TXT 48V golf cart. By implementing one or more of these modifications, you can unleash the full potential of your cart and improve its overall performance.
Upgrade the Controller
The controller is the primary component that governs the speed and torque of your golf cart. Upgrading to a higher amperage controller will allow for more power to be delivered to the motor, resulting in increased speed and acceleration. There are several aftermarket controllers available, such as the Alltrax XCT, Navitas, and Curtis, which are compatible with the EZGO TXT 48V golf cart.
Install a High-Speed Motor
A high-speed motor can significantly enhance the performance of your golf cart. Aftermarket motors, such as the Admiral MOT-A2 or D&D Motor Systems’ high-speed offerings, are specifically designed to increase the top speed of your cart without sacrificing torque. Be sure to select a motor compatible with your cart’s voltage and controller specifications to ensure optimal performance.
Upgrade the Solenoid
The solenoid is responsible for controlling the flow of electrical current between the battery and the motor. Upgrading to a heavy-duty solenoid, such as the MZJ-200A, can handle higher amperage and provide more power to the motor. This upgrade is particularly crucial when using a high-amperage controller or a high-speed motor to prevent potential damage to the electrical system.
Change the Gear Ratio
Altering the gear ratio of your golf cart’s differential can have a significant impact on its top speed. To achieve a higher top speed, consider installing a high-speed gear set with a lower gear ratio. Keep in mind that a lower gear ratio may result in reduced torque and hill-climbing ability, so it’s essential to find the right balance for your specific needs.
Use Larger Tires
Installing larger tires can increase the top speed of your golf cart by effectively changing the gear ratio. Taller tires have a larger circumference, meaning they cover more distance with each rotation. This translates to a higher top speed, albeit with a slight decrease in acceleration.
