Speed and low cost do not compute
Welcome to the madness
You could go with a speed chip aka freedom mode

Default Re: More speed

Welcome to BGW! (Or at least the first post. )

1990 was a decade before PDS drive systems with "Speed Chips" existed and 5 years before the DCS drive system with a Sepex motor was produced, so you have a series wound motor.

With a series wound motor, there are three ways to increase speed.
1. Change the final drive ratio, which also reduces torque. (Taller tires and/or gear ratio)
2. Increase battery pack voltage. (48V)
3. Install a high speed motor.

In each case, the rest of the drive system (High current cables, Controller, Solenoid and F/R Switch) will have to be upgraded to deliver the Amps needed to propel the cart faster.

What is the cart's speed at present?
What speed are you wanting to get to?
