Why Are Golf Carts Not Fast?
Golf carts are made for specific uses. They move people and gear on a golf course. This means they do not need to go fast. Their main job is to be quiet and easy to drive. They also need to save power. Speed is not a top goal for them.
Most golf carts leave the factory with speed limits. These limits keep drivers safe. They also make sure the cart’s parts last a long time. The parts are not built for very high speeds. Factory settings keep the cart running well. They also meet local rules for low-speed vehicles.
Many factors limit a golf cart’s speed. The motor size is one limit. The battery power is another. The way the controller works also plays a big part. The size of the tires matters. Even the way the gears are set up affects speed. Knowing these limits helps you pick the right golf cart speed upgrades.
Getting Ready for Speed Changes
Before you make any changes, plan carefully. Think about how you will use the cart. Do you need a little more speed? Or do you want a lot more speed? More speed often means more cost. It can also mean less battery life.
Consider your budget. Some changes are cheap. Others cost a lot of money. Think about your skills too. Can you do the work yourself? Or will you need a pro? DIY projects can save money. But they need tools and know-how.
Safety is key. Making a cart go faster changes how it handles. It might need better brakes. It might need stronger suspension. Always put safety first. Also, check local laws. Some areas have rules on how fast golf carts can go.
Tools You Might Need
Having the right tools helps a lot. Here are some common ones:
- Wrench Set: For nuts and bolts.
- Socket Set: Also for nuts and bolts.
- Screwdriver Set: Different types and sizes.
- Wire Strippers/Crimpers: For electrical work.
- Multimeter: To check electrical currents.
- Floor Jack: To lift the cart.
- Jack Stands: To keep the cart stable.
- Safety Glasses: To protect your eyes.
- Gloves: To protect your hands.
Major Electric Golf Cart Performance Modifications
Many different ways can make your electric golf cart faster. These range from simple adjustments to major component swaps. Each method affects speed, cost, and difficulty. Let’s look at the main options for electric golf cart performance modifications.
Boosting Power: The Controller
The controller is like the brain of your golf cart. It tells the motor how much power to use. It controls the speed and how fast the cart starts. Changing this part is one of the best golf cart speed upgrades.
Grasping How Controllers Work
A golf cart controller takes power from the battery. It sends this power to the motor. It makes sure the motor gets the right amount. Factory controllers often limit power. They do this to save battery life. They also do it to keep speeds low.
An upgrade golf cart controller can send more power. This lets the motor spin faster. It gives you higher top speeds. It also makes your cart start faster. This means better electric golf cart acceleration tips.
Types of Controllers
- Stock Controller (Reprogramming): Some newer carts let you change settings. You might use a hand-held programmer. This can remove speed limits. It is simple but gives only small gains.
- Aftermarket Controller: These controllers are built for speed. They handle more power. They can give a big boost to your cart’s speed. They are often a top choice for serious upgrades.
Installing a New Controller
- Step 1: Disconnect Battery: Always turn off the cart. Remove the main battery cable first. Safety is vital.
- Step 2: Find the Controller: It is usually in a box under the seat. It will have many wires.
- Step 3: Label Wires: Take photos of how wires connect. Label each wire. This helps when putting the new one in.
- Step 4: Remove Old Controller: Unbolt it. Disconnect all wires carefully.
- Step 5: Install New Controller: Bolt the new controller in place. Connect wires exactly as before. Check your labels and photos.
- Step 6: Connect Battery: Put the main battery cable back. Test the cart slowly first.
Pros and Cons of Controller Upgrades
| Feature | Pros | Cons |
|---|---|---|
| Speed Gain | Good to excellent | Might need other parts to handle power |
| Cost | Medium to High | Can be a big investment |
| DIY Ease | Moderate (needs careful wiring) | Can be complex for beginners |
| Impact | Better top speed and acceleration | Can drain batteries faster |
| Safety | Needs brake upgrades for higher speeds | Increased wear on other components |
An upgraded controller is often the first step to increase golf cart top speed. It helps your cart use its power better.
More Power: The Battery System
The battery system is the fuel tank of your electric golf cart. It gives power to the motor. More power means more speed. This is a crucial part of golf cart speed upgrades.
Deciphering Battery Power
Most golf carts use 36-volt or 48-volt systems. The voltage tells you how much electrical “push” the system has. Higher voltage means more power. This leads to more speed and torque. Torque is the turning power. It helps the cart climb hills.
A higher voltage golf cart battery system directly impacts speed. Upgrading from 36V to 48V is a common change. Some even go to 72V. This is a big step for speed.
Ways to Upgrade Batteries
- More Volts: Add more batteries to increase total voltage. For example, six 8-volt batteries make 48V. Four 12-volt batteries also make 48V.
- Better Amperage-Hour (Ah): This measures how long batteries last. Higher Ah means longer run time. It does not directly mean more speed. But, it helps keep speed constant as batteries drain.
- Lithium Batteries: These are newer and lighter. They hold a charge better. They give full power until they are nearly empty. They can be more expensive. But they last longer and perform better.
Changing Your Battery System
- Step 1: Plan Your Voltage: Decide if you want 48V, 72V, etc. This depends on your controller and motor.
- Step 2: Buy New Batteries: Get batteries that fit your chosen voltage. Make sure they fit the battery tray.
- Step 3: Disconnect Old Batteries: Take photos of wiring. Label everything. Remove old batteries one by one. They are heavy.
- Step 4: Clean Battery Tray: Make sure the area is clean and dry. Check for rust.
- Step 5: Install New Batteries: Place new batteries. Connect them in series. Follow wiring diagrams carefully. Always connect positive to negative.
- Step 6: Reconnect Cart: Hook up the main battery cables last. Charge the new batteries fully.
Pros and Cons of Battery Upgrades
| Feature | Pros | Cons |
|---|---|---|
| Speed Gain | Good (especially higher voltage) | Can be limited by stock motor/controller |
| Cost | High (new batteries are expensive) | May need a new charger too |
| DIY Ease | Moderate (heavy, needs careful wiring) | Batteries are heavy and can be tricky to lift |
| Impact | Higher top speed, more torque, longer runs | Adds weight (less for lithium) |
| Safety | Needs proper wiring and safety gear | Risk of electric shock if not careful |
A higher voltage golf cart battery system is often done with a controller upgrade. They work well together to boost speed.
More Muscle: The Motor
The motor is what spins the wheels of your electric golf cart. It turns electrical energy into motion. A stronger motor directly means more speed. This is a top way to increase golf cart top speed.
Interpreting Motor Power
Golf cart motors come in different strengths. Stronger motors can handle more power from the battery and controller. This lets them spin faster. It also gives them more torque. More torque means quicker starts and better climbing.
A high speed golf cart motor is designed to spin very fast. Some are made for more torque (for hills). Others are made for more speed on flat ground. You need to pick the right motor for your needs.
Types of Motors
- Stock Motor (if compatible): Sometimes, your old motor can handle more power. If you only upgrade the controller, your stock motor might perform better. This is not always the case.
- High-Speed Aftermarket Motor: These motors are built for speed. They are stronger and more efficient. They are designed to work with upgraded controllers and battery systems.
- High-Torque Aftermarket Motor: These are great for hilly areas or heavy loads. They offer great acceleration but might not give the highest top speed.
Replacing Your Golf Cart Motor
- Step 1: Disconnect Power: Turn off the cart. Remove the main battery cable.
- Step 2: Access the Motor: The motor is usually near the rear axle. You might need to lift the cart.
- Step 3: Disconnect Motor Wires: Take photos and label all wires. Unbolt the wires from the motor.
- Step 4: Remove Old Motor: Unbolt the motor from its mount. It can be heavy. Get help if needed.
- Step 5: Install New Motor: Bolt the new motor into place. Connect all wires correctly. Refer to your labels.
- Step 6: Reconnect Battery: Put the main battery cable back. Test the cart slowly first.
Pros and Cons of Motor Upgrades
| Feature | Pros | Cons |
|---|---|---|
| Speed Gain | Excellent (especially high-speed motors) | Can drain batteries faster |
| Cost | High | Often needs controller and battery upgrades |
| DIY Ease | Moderate to Hard (heavy lifting, tight spaces) | Can be complex for beginners |
| Impact | Much higher top speed, better acceleration | Can cause more wear on other parts |
| Safety | Requires brake and suspension checks | Must match with controller and battery |
A high speed golf cart motor is a key step for serious speed gains. It works best when combined with an upgraded controller and higher voltage batteries.
Shifting Gears: The Gear Ratio
The gear ratio in your golf cart’s differential decides how fast the wheels spin compared to the motor. Changing this is a direct way to alter speed. This is known as a golf cart gear ratio change.
Fathoming Gear Ratios
Think of a bicycle. When you are in a low gear, you pedal many times for one wheel turn. This is good for climbing hills. When you are in a high gear, you pedal fewer times for one wheel turn. This is good for speed.
Golf carts have a fixed gear ratio. A higher gear ratio (e.g., 12.44:1) means more torque, less speed. A lower gear ratio (e.g., 6.5:1) means less torque, more speed. For increase golf cart top speed, you want a lower numerical gear ratio.
How to Change Gear Ratios
- Buy New Gears: You need a gear set specifically made for your cart model.
- Access the Differential: This is the axle housing where the gears are. It’s usually under the cart.
- Drain Oil: You will need to drain the gear oil first.
- Remove Old Gears: This involves opening the differential case. It can be complex. You need special tools.
- Install New Gears: Put the new gears in. Make sure they are aligned perfectly.
- Refill Oil: Put new gear oil back in.
- Seal and Test: Seal the differential. Test for leaks and proper function.
Pros and Cons of Gear Ratio Changes
| Feature | Pros | Cons |
|---|---|---|
| Speed Gain | Good | Less torque for hills/heavy loads |
| Cost | Medium | Often needs professional installation |
| DIY Ease | Hard (precise work, special tools) | Incorrect install can damage the differential |
| Impact | Higher top speed, lower acceleration | Can put more strain on motor |
| Safety | Needs brake upgrades for higher speeds | Not ideal for hilly terrain |
A golf cart gear ratio change is a good option if you drive mainly on flat ground. It can give a good speed boost without changing electrical parts. But it is one of the harder electric golf cart performance modifications.
Simple Speed Boosts: Speed Chip or Code
Some golf carts have a built-in speed limit. This limit can sometimes be changed with a special chip or code. This is a quick way to get more speed. This is called a golf cart speed chip install.
What is a Speed Chip or Code?
Many newer golf carts have an electronic controller. This controller has software inside. This software limits the cart’s speed. A “speed chip” or a dealer code can change these settings. It can remove or raise the speed limit.
This method often works for golf carts made by brands like EZ-GO, Club Car, or Yamaha. Each brand might have its own way to do it.
How to Use a Speed Chip or Code
- For EZ-GO PDS Models: You might need a “speed chip” that plugs into the controller. It changes the speed mode.
- For Club Car IQ Models: You might need a special diagnostic tool. A golf cart dealer or service center can do this for you. They plug into the cart and change the settings.
- For Yamaha Models: Some Yamaha carts have a “speed code” that can be entered. This often needs a dealer tool.
Pros and Cons of Speed Chip/Code
| Feature | Pros | Cons |
|---|---|---|
| Speed Gain | Small to Moderate | Only works on certain cart models |
| Cost | Low to Medium (chip cost or dealer fee) | May void warranty |
| DIY Ease | Easy (if just plugging in a chip) | Hard (if special tools or dealer visit needed) |
| Impact | Slightly higher top speed | Not a huge power boost, mainly unlocks existing |
| Safety | Minimal added risk | Still consider brake checks |
A golf cart speed chip install is a simple and often affordable first step. It can give a small but noticeable increase golf cart top speed.
DIY Golf Cart Speed Increase Tips
Not every speed boost needs new parts. Some simple things you can do can help your cart go a little faster. These are great for a DIY golf cart speed increase.
Tire Pressure
- Check Often: Tires lose air. Low tire pressure makes your cart work harder. This slows it down.
- Inflate Correctly: Check the tire’s side wall. It shows the right pressure. Use a tire gauge. Proper pressure makes rolling easier. This adds a little speed.
Tire Size
- Bigger Tires: Putting on slightly larger tires can make your cart go faster. Why? Each spin of the wheel covers more ground.
- How Much? Going from an 18-inch tire to a 20-inch tire can add a few MPH.
- Downsides: Bigger tires can use more power. They can also make the cart ride higher. This affects stability. They might rub against the cart body.
Reducing Weight
- Lighter Cart: A lighter cart needs less power to move. Remove extra seats or heavy accessories.
- What to Remove: Tools, unused sand bottles, or anything heavy that you do not need.
- Benefits: Even a small weight loss can give a slight speed increase. It also helps battery life.
Check for Drag
- Brakes Dragging: Sometimes brakes can rub a little. This slows the cart down. Check if your brakes are fully releasing.
- Bad Bearings: Wheel bearings can get old and cause friction. This can slow the cart. Replacing them can help.
- Alignment: If your wheels are not straight, it creates drag. Get an alignment if needed.
Regular Maintenance
- Clean Connections: Make sure all battery and motor cables are clean. Remove any rust or dirt. Bad connections waste power.
- Charge Batteries Well: Always charge your batteries fully. Old, weak batteries lose speed.
- Lubrication: Keep moving parts greased. This reduces friction.
These DIY golf cart speed increase tips are cheap or free. They are great starting points before spending big money.
Electric Golf Cart Acceleration Tips
Making a cart go faster is not just about top speed. It is also about how fast it gets to that speed. This is acceleration. Good electric golf cart acceleration tips can make your ride feel much zippier.
- Controller Upgrade: As mentioned, a new controller gives a huge boost to acceleration. It sends more power faster to the motor.
- High-Torque Motor: If you want quick starts, a high-torque motor is key. It delivers power right away. This is great for climbing hills too.
- Higher Voltage Battery: More volts mean more power. This extra power directly translates to quicker acceleration.
- Lighten the Load: The less weight the cart has to pull, the faster it will speed up. Travel lighter whenever possible.
- Proper Tire Pressure: Correct tire pressure reduces rolling resistance. This makes it easier for the cart to get moving.
- Smooth Pedal Control: Apply the throttle smoothly, not suddenly. This helps the controller and motor work more efficiently. Avoid “punching” the pedal.
Good acceleration makes driving more fun. It makes your cart feel more powerful.
Safety First: Must-Do Checks After Upgrades
Making your golf cart faster changes how it behaves. Safety must be your top concern. Faster speeds mean you need to stop quicker. You need to control the cart better.
Brake System Checks
- Upgrade Brakes: For any major speed increase, better brakes are a must. Stock brakes might not be enough. Look into heavy-duty brake pads or disc brake kits.
- Inspect Often: Check your brake pads and drums regularly. Make sure they are not worn down.
- Brake Fluid: If your cart has hydraulic brakes, check the fluid level. Make sure it is clean.
Suspension and Steering
- Stronger Suspension: At higher speeds, the cart can feel bouncy. Upgraded shocks or leaf springs can help. They make the ride smoother. They also keep the cart stable.
- Steering Play: Check for looseness in the steering wheel. Tighten any loose parts. This helps you control the cart better at speed.
- Wheel Bearings: Check wheel bearings for wear. Bad bearings can cause wobbles. They can also affect how the cart turns.
Tires
- Speed Rating: Not all tires are made for high speeds. Check the speed rating on your tires. Get tires that can handle your new top speed.
- Condition: Always use tires with good tread. Worn tires can slip.
Driver Awareness
- Practice Driving: Get used to the faster speed in a safe area. Learn how the cart handles.
- No Reckless Driving: Do not drive too fast. Do not turn too sharply. Golf carts can tip over.
- Passenger Safety: Make sure all passengers know about the speed increase. They should hold on tightly.
Never ignore safety. A fast cart without good control is very dangerous.
Legal Rules and Regulations
Local laws on golf cart speed vary a lot. Before you make your cart faster, know the rules. You could get a ticket if your cart is too fast.
Street Legal vs. Off-Road
- Golf Course: On a golf course, rules are usually about safety. Speed limits might be set by the course itself.
- Public Roads: Many places allow golf carts on certain roads. These are called “low-speed vehicles” (LSVs).
- LSV Speed Limits: LSVs usually have a top speed limit. This is often between 20-25 MPH. If your cart goes faster, it might not be street legal anymore.
- Other LSV Rules: LSVs often need headlights, taillights, turn signals, seat belts, and a windshield. Make sure your cart meets all these rules if you plan to drive on public roads.
Insurance
- Check Policy: Your golf cart insurance might not cover a modified cart. Tell your insurance company about any speed changes.
- Increased Risk: A faster cart means more risk. Your insurance might cost more.
Always check with your local Department of Motor Vehicles (DMV) or local law enforcement. They can tell you the exact rules for your area.
Cost of Speed: What to Expect
The cost of making your golf cart faster can vary widely. It depends on how much speed you want. It also depends on which parts you upgrade.
