Ultimate Guide: How To Make A Golf Cart Go Faster Today

Can you make a golf cart go faster? Yes, you absolutely can! Many golf cart owners want more speed. Making a golf cart faster involves specific changes. These changes depend on if your cart runs on gas or electricity. You need to know what you are doing. Always put safety first. We will explore safe and effective ways to boost your cart’s speed. This guide will show you how to give your cart a true golf cart speed upgrade.

Deciphering Your Golf Cart Type

Before you start any work, know your cart. Is it electric or gas? This is the first step. Each type needs different upgrades.

Electric Golf Carts

Electric carts run on batteries and an electric motor. They are quiet. They need no gas. They are popular for neighborhoods. Most electric golf carts are easy to upgrade for speed.

Gas Golf Carts

Gas carts use a small engine. They run on fuel. They sound like a car engine. Gas carts can also get speed boosts. The methods are different from electric carts.

Safety First: Essential Checks Before Any Mod

Adding speed means your cart will go faster. This puts more stress on parts. Always check these safety items first:

Brakes: Your brakes must be strong. They need to stop your faster cart. Test them fully.
Tires: Good tires are key. They need enough tread. They must hold high speeds.
Suspension: A good suspension keeps the ride smooth. It helps control the cart. Check for worn parts.
Steering: Make sure the steering is tight. No loose play. You need full control at speed.
Frame: Look for any damage to the cart’s frame. A strong frame is vital.

It is wise to upgrade brakes and suspension first. This makes your cart safer for higher speeds.

Electric Golf Cart Performance Mods: Boosting Your Ride

Electric carts offer many ways to gain speed. These electric golf cart performance mods are common and effective.

Raising the Voltage

One simple way to make an electric cart faster is to increase golf cart voltage. More voltage means more power. This gives you higher speeds.

How to Increase Voltage

Most golf carts are 36-volt or 48-volt.
* 36-volt carts: You can change to a 48-volt system. This means adding two 6-volt batteries. Or you can switch to six 8-volt batteries. This makes the cart run with more power.
* 48-volt carts: You can upgrade to a 72-volt system. This needs more batteries. It also needs a new controller and motor.

What You Need for a Voltage Boost

New Batteries: You will need more batteries. Or you will need batteries with higher volts.
Upgraded Controller: Your old controller might not handle higher voltage. You will likely need a new one.
Compatible Motor: Check if your motor can take the extra voltage. Some motors can handle a small jump. Bigger jumps need a new motor.
Heavy-Duty Wires: Stock wires might be too thin. Thicker wires are safer. They prevent overheating.

Table: Voltage Upgrade Overview

Current System	Target System	Battery Needs	Other Parts Needed	Expected Speed Gain
36-volt	48-volt	Add two 6V, or replace	Controller, wires	4-7 mph
48-volt	72-volt	Add more 8V, or replace	Controller, motor, wires	8-15 mph

Increasing voltage is powerful. But it can wear out parts faster.

The Golf Cart Controller Upgrade

The controller is like the brain of your electric cart. It sends power from the batteries to the motor. A stock controller limits speed. A new, bigger controller can send more power. This boosts speed. It is a major golf cart controller upgrade.

Why Upgrade Your Controller?

More Amps: Higher amperage controllers deliver more power. This lets the motor spin faster.
No Speed Limiting: Many factory controllers limit speed. An aftermarket one removes these limits.
Better Torque: You get more pulling power. This helps on hills.

Choosing a New Controller

Look for controllers from brands like Alltrax or Navitas. Match the controller to your motor and battery voltage. Get a controller that can handle more amps than your current one. Many kits come with a new solenoid too. This is often needed.

Installation Steps

Safety First: Disconnect all batteries. Wear safety gear.
Remove Old Controller: Take out the old controller. Note how wires connect. Take pictures.
Install New Controller: Mount the new controller. Connect wires carefully. Follow the new controller’s guide.
Connect Batteries: Reconnect your batteries. Test the cart at low speed first.

A controller upgrade is one of the best custom golf cart speed modifications you can make.

The Golf Cart Motor Upgrade for Speed

The motor turns power into motion. A stronger motor makes your cart faster. A golf cart motor upgrade for speed is a big step.

Types of Motors

Stock Motors: These are basic. They are good for normal use.
High-Speed Motors: These motors are built for speed. They have fewer windings. They spin faster.
High-Torque Motors: These are for hills and heavy loads. They offer less speed but more pulling power.
Balanced Motors: These offer a good mix of speed and torque.

For speed, you want a high-speed or balanced motor. Match the motor to your controller and voltage. A 48V motor will spin faster on 48V than on 36V. A 72V motor will be fastest on 72V.

Installation Tips

Replacing a motor is a bit complex.
1. Disconnect Power: Always unhook the batteries.
2. Remove Old Motor: Unbolt and take out the old motor.
3. Install New Motor: Put the new motor in place. Bolt it down tightly.
4. Connect Wires: Connect the motor wires to the controller. Double check all connections.

A new motor often goes hand-in-hand with a controller upgrade. They work best as a team.

Golf Cart Speed Chip Installation / Speed Sensor

Some electric golf carts have a speed sensor. This sensor limits top speed. It is often found on EZ-GO and Club Car models. A simple golf cart speed chip installation or magnet change can remove this limit.

How it Works

Speed Sensor Magnet: In many carts, a magnet on the motor senses speed. A factory magnet tells the controller to slow down at a certain speed.
High-Speed Magnet: You can replace this magnet. A “speed magnet” or “speed chip” fools the controller. It tells the controller the cart is going slower than it is. This lets the cart reach higher speeds.

Benefits

Cheap: This is one of the cheapest speed mods.
Easy: It is fairly simple to install.
Quick Speed Gain: You can see an instant speed boost.

This mod is usually for carts that already have a speed sensor. It might not work on all models. It’s often the first step in seeking a golf cart top speed increase.

High-Speed Golf Cart Gears

Changing the gears in your golf cart’s rear axle can also add speed. This is like changing gears in a car. High-speed golf cart gears make the wheels turn faster for each spin of the motor.

How Gears Work

Gear Ratio: This is the number of times the motor shaft turns for one turn of the wheel.
Lower Ratio: A lower gear ratio means fewer motor turns for one wheel turn. This equals more speed.
Higher Ratio: A higher ratio means more motor turns for one wheel turn. This equals more torque but less speed.

Downsides

Loss of Torque: With high-speed gears, you lose some pulling power. This can make climbing hills harder.
Complex Install: Changing gears in the rear axle is a big job. It needs special tools and know-how. It is not for beginners.
Cost: Gear sets can be costly. Plus, you might need a mechanic to install them.

Despite the challenges, high-speed gears are effective. They offer a direct way to achieve a golf cart top speed increase.

Gas Golf Cart Engine Tuning: Unleashing Power

Gas golf carts need different methods to go faster. The focus is on the engine. Gas golf cart engine tuning can make a big difference.

Adjusting the Governor

Most gas golf carts have a governor. This limits the engine’s RPMs (revolutions per minute). It stops the cart from going too fast.

How to Adjust

Find the Governor: It is usually a small box or rod connected to the engine. It may be near the carburetor.
Loosen the Nut: There is often a nut on the governor arm. Loosen it.
Adjust Linkage: Move the linkage to allow more throttle. Tighten the nut.
Test: Test the cart in a safe area. Do not over-adjust. Too much speed can damage the engine.

Be careful with this adjustment. Too high an RPM can blow the engine. This is a basic form of golf cart top speed increase.

Upgrading the Clutch

The clutch transfers power from the engine to the wheels. A stock clutch might not work well at higher RPMs. An upgraded clutch can improve speed and acceleration.

Why Upgrade?

Better Engagement: A performance clutch engages more smoothly.
Higher Engagement RPM: It can be set to engage at higher engine speeds. This gives more power off the line.
Durability: Aftermarket clutches are often stronger. They handle more stress.

Types of Clutches

Primary Clutch: Connects to the engine.
Secondary Clutch: Connects to the rear axle.
You might upgrade one or both. Many parts are available, like heavier springs or different weights.

A clutch upgrade works well with other engine mods. It helps transfer the added power to the wheels.

Enhancing Air Intake and Exhaust

Just like a car, a golf cart engine needs to breathe. Better airflow in and out helps.

Air Intake

Performance Air Filter: Replace the stock air filter. A high-flow air filter lets more air into the engine. This means more power.
Cold Air Intake: A cold air intake kit brings cooler, denser air to the engine. Cooler air has more oxygen. This boosts power.

Exhaust System

Performance Exhaust: A less restrictive exhaust system lets engine gases escape faster. This reduces back pressure. It can add a few extra horsepower.
Muffler Delete: Some people remove the muffler. This makes the cart very loud. It can add a little power but is often not worth the noise.

These changes are part of gas golf cart engine tuning. They help the engine run more freely.

Carburetor Adjustments or Upgrades

The carburetor mixes air and fuel. Proper tuning means the engine runs at its best.

Adjustments

Idle Mixture Screw: Adjust this for a smooth idle.
Main Jet: For more power, you might need a larger main jet. This lets more fuel into the engine at high RPMs.

Upgrades

Aftermarket Carburetor: A larger, performance carburetor can flow more fuel and air. This gives a bigger power boost.
Fuel Pump: With a bigger carburetor, you might need a stronger fuel pump. It ensures enough fuel gets to the engine.

Carburetor work can be tricky. If you are not sure, get help from a pro.

Universal Speed Enhancements: Good for Any Cart

Some upgrades help both electric and gas carts. These focus on how the cart moves.

Lighter Wheels and Performance Tires

The wheels and tires affect speed and handling.

Lighter Wheels

Reduce Unsprung Weight: Lighter wheels mean less weight not supported by the suspension. This helps the cart accelerate faster. It also improves handling.
Material: Aluminum wheels are lighter than steel.

Performance Tires

Low Rolling Resistance: Tires designed for low rolling resistance use less energy to move. This adds speed.
Street Tires: For paved surfaces, street tires are best. They offer good grip and less friction than off-road tires.
Correct Size: Larger diameter tires can increase top speed. But they can also hurt acceleration. They also need enough fender clearance. This is a subtle golf cart speed upgrade.

Suspension Upgrades

A better suspension helps control the cart at higher speeds.

Heavy-Duty Springs: Stronger springs reduce body roll. This makes the cart feel more stable.
Performance Shocks: Better shocks absorb bumps. They keep the tires on the ground. This improves handling and safety.
Lift Kits: While lift kits often add larger tires (which can boost speed), their main purpose is ground clearance. They can also affect stability. Choose wisely.

A stable cart is a safe fast cart. This is part of custom golf cart speed modifications.

Beyond Speed: Essential Safety and Stability

Making a cart go faster is fun. But it adds risks. Always think about safety.

Upgrading Brakes

This is not a choice, it is a must. Faster carts need stronger brakes.

Disc Brake Kits: Many golf carts have drum brakes. Disc brakes offer much better stopping power. They are a great upgrade.
Heavy-Duty Brake Pads: Even with drum brakes, better pads can improve stopping.
Regenerative Braking (Electric Carts): Some electric cart controllers offer better regen braking. This helps slow the cart.

Never skimp on brakes. Your life may depend on them.

Enhancing Stability

Higher speeds make a cart less stable.

Wheel Spacers: These push the wheels out further. This widens the stance. It helps prevent rollovers.
Lowering Kits: For street use, lowering the cart’s center of gravity makes it more stable. This improves handling on turns.
Wider Tires: Wider tires give a larger contact patch. This improves grip and stability.

Combine these stability mods with speed mods for best results.

Legal and Practical Considerations

Before you hit the road with your faster cart, know the rules.

Local Laws and Regulations

Speed Limits: Many areas have speed limits for golf carts. Going over these limits can lead to fines.
Street Legal vs. Off-Road: Is your cart street legal? Adding speed might change its legal status. Check local rules.
Registration/Insurance: Faster carts might need different registration or insurance.

Always check your local DMV or city office for rules.

Maintenance After Mods

A faster cart needs more care.

Electric Carts:
- Battery Care: Higher voltage and more power drain batteries faster. Keep them charged. Check water levels often (if applicable).
- Motor/Controller Heat: Monitor for overheating. Upgraded parts generate more heat.
Gas Carts:
- Oil Changes: Change engine oil more often.
- Spark Plugs: Check and replace spark plugs regularly.
- Air Filters: Clean or replace air filters often.

Regular checks and maintenance keep your faster cart running well.
