Thatís Great, Now How Can I Make My Golf Car Go Faster?
If you have a Gas Golf Car:
Install larger tires - the easiest and
Remove the governor - may reduce the life
expectancy of the engine.
Reset the governor settings to increase torque
- a mechanic can do it or provide the technical assistance for
Change to high-speed gears - maybe the best
alternative but use the services of a skilled mechanic to make
sure there is no added rear-end noise.
If you have an Electric Golf Car:
Install larger tires.
Change to high-speed gears.
Field coil upgrade - most cost effective with
adequate results without requiring advanced mechanical skill.
Change the field coil in a 2-hp motor (a standard in golf
cars) and it can become a 3.5 hp motor. Does not need to
upgrade the controller. You can only upgrade if you have a GE
motor, the casing can be removed, and the existing field coil
is not glued with epoxy, but wired.
Change to a high-speed motor - next easiest
but may require changing the controller depending upon the
demands made on the motor. See notes on the controllers below.
High-speed gears with high-speed motors is not
recommended. Better option, depending on terrain, is
installing a high-speed motor with a high-performance motor
controller and using larger tires.
Special Notes On Electric Golf Cars:
If you set up your electric golf car to go to
55 mph it may result in SERIOUS INJURY OR DEATH.
Please note that the Federal Motor Vehicle
standard speed for low-speed neighborhood vehicles can not
exceed 25 mph. Thus, do not operate your high-speed golf car
on public roads at speeds of more than 25-mph.
To calculate the top speed of an electric golf
car, use the equation below:
RPMís of motor X Tire Radius (in inches) / Gear Ratio X 168 =
Miles per Hour
Example: A golf car with 3000 RPM motor with an 8" tire and a
12.44:1 gear ratio (a standard in golf cars):
3000 X 8 / 12.44 X 168 = 11.48 mph (standard speed for golf
with 10" tires, top speed is 14.35 mph
with 12" tires, top speed is 17.23 mph
Available gear ratios: 8:1 and 6:1
8" tires, 3000 RPM, 8:1 gear ratio, top
speed is 17.85 mph
8" tires, 3000 RPM, 6:1 gear ratio, top
speed is 23.81 mph.
12" tires, 4400 RPM, tops speed is 52.38
Standard golf car controllers deliver a
maximum of 225-275 amps sufficient for golf car applications
and flat ground use. If you wish to install a larger 3.5 or 5
hp motor, itís small size may cause overheating. You can
upgrade the 225-275 controller without them overheating.
However, with a 3.5 or 5 hp motor, a 275 amps controller is
If you use the car for off-road use, hunting
or hill climbing, increase the motor size to 3 Ĺ hp, 5 hp or 7
hp to give the golf car the needed torque to get uphill faster
and for quick acceleration. Again, you should consider
upgrading your controller. Orange County Monster Carts offers
upgrades to 400 amps, 500 amps and 650 amps to prevent
overheating. In addition, these upgraded controllers increase
the voltage in 36-volt cars to 48-volts.
If you intend to use your golf car for
street-use, we recommend upgrading the controller to handle
If you have a 3 Ĺ hp motor, we recommend
upgrading the controller to 400 amps.
If you have a 5 or 7 hp motor, we recommend upgrading the
controller to 500 amps.
F-N-R (forward-neutral-reverse) switches may
not perform efficiently when using high current motors. Orange
County Monster Carts can offer you controllers that will
eliminate the F-N-R switch (used with series wound motors)
since they are handled by the controller.
We have available the upgraded high-powered
motor 400, 500, or 650 amps controllers for EZGO, Club Car and
Yamaha. These are simple and inexpensive alternatives to those
offered by the manufacturers.
