Yamaha G29 Gas Speed Upgrade

Till now we have learned what we should do in order to increase the speed of the Yamaha G29 Gas. Now let’s get into details and instructions on how to do the upgrades that have been mentioned earlier.

Remove the Governor

The governor is the one that is limiting the top speed of the golf cart. Removing the governor will surely give the cart the flexibility to move faster.

Firstly you have to remove the cable from the carburetor. After that follow the cable to the governor and detach the governor spring.

Disconnect the gas pedal and reattach it to the carburetor. The gas pedal shaft might need some adjustments after the process.

If you have the tools and know how to complete the whole process, then it should not cost you anything. But if you need any technical support then you need to pay for that labor cost only.

Engine Upgrade

The Yamaha G29 Gas has stock engines in it which are much more efficient. But if you need more performance out of it then you need to upgrade it.

You can change the motor of the engine to get better performance. You can get a more powerful motor from your nearest golf exterior manufacturing company.

Or you can order one online. The higher performing engine motor will produce more torque, which will improve the initial pick up as well as uphill driving. 

It can cost you between $700 to $2000 to get a new engine motor installed. However, you will need to spend on labor costs unless you are willing to install it yourself.

Speed Controller Upgrade

The speed controller upgrade is a good way to upgrade the speed of the Yamaha G29 Gas golf cart. 

As the speed controller controls the cart’s acceleration and deceleration as well as the speed of the cart while it is running.

So getting a controller that allows more current and voltage to your motor can increase the speed of the cart.

You can get a better performing speed controller between $500 to $1500 from any reliable golf cart manufacturing company. 

Torque Converter Installation

Installing a torque converter can increase the number of torque that the wheels are getting from the engine. 

The amount of torque that the motor is producing is multiplied by the torque converter’s gear ratio.

For instance, if your golf cart is able to produce 5ft-lb of torque and you get a torque converter that has a gear ratio of 3:1, the output you would be getting is 15ft-lb. A torque converter can cost you between $100 to $250.

High Performance Clutch Installation

Installing a high performance clutch can increase torque. The clutch helps the motor to engage and disengage from the drivetrain. 

Installing a high performance clutch helps the motor to engage at high RPM, which will produce more torque from the engine.

In this way you can get better initial power out of the cart while using the stock engine. You can buy a high performance clutch from online between $75 to $150. 

Cold Air Intake Installation

A cold air intake is an aftermarket product that brings cool air directly into the engine. 

Installing a cold air intake is beneficial for more powerful engines that are often used at high speed.

By letting the engine get more air, it improves performance and helps to keep the engine safe from any heating damage.

Installing it can cost you $300 to $500 excluding the installation cost.

Upgrade to Bigger Tires

Upgrading to bigger tires is the easiest way to increase speed without touching the engine or by tweaking any motors. 

The larger the tires are, the faster the cart will run. If there is no additional weight on the back, the Yamaha G29 Gas can accommodate up to a 20″ tall all-terrain tire (20×10-10, 20×10-12) without a raise kit.

Any taller tires will require a lift kit on the G29 Gas. It will increase the speed of the cart by 2 to 4 mph without doing any expensive mods.

Bigger tires such as 20” tall can cost between $250 to $350.
