How to make a electric golf cart 75mph?

To make an Electric Golf Cart reach a speed of 75mph, there are several modifications and upgrades that need to be made. It is important to note that modifying a golf cart for excessive speeds may not be legal or safe, so it is recommended to consult with experts or professionals before attempting any modifications.

Here are some general steps that could be taken to increase the speed of an Electric Golf Cart:

1. Motor upgrade: Replace the existing motor with a higher-powered motor that can handle higher speeds. Look for motors specifically designed for golf cart applications.

2. Controller upgrade: Upgrade the controller to handle the increased power and provide better acceleration and speed control.

3. Battery upgrade: Install high-performance batteries with a higher voltage and capacity to deliver more power to the motor. Consider Lithium-ion batteries for their power-to-weight ratio and longevity.

4. Gear ratio modification: Adjust the gear ratio of the golf cart's transmission to optimize its performance at higher speeds. This can help in achieving higher top speeds.

5. Tire upgrade: Install low-profile, high-performance tires designed for higher speeds. This can improve grip and reduce rolling resistance.

6. Aerodynamic modifications: Make aerodynamic modifications to reduce drag and improve the golf cart's overall efficiency at higher speeds. This can include adding fairings, optimizing the body design, and reducing any unnecessary weight.

7. Safety considerations: It is crucial to install additional safety features, such as improved brakes, seat belts, and reinforced chassis, to ensure the golf cart can handle higher speeds safely.

Remember, modifying a golf cart for higher speeds may void warranties, violate regulations, and compromise safety. It is important to consult professionals and LOCAL authorities before making any modifications.
