Or the battery pack may just not have the oomph needed. In any case adding voltage (42v) will help

I was amazed by the difference adding a seventh 6V battery made.

I know - huh? - Western took Ezgo carts and added the 7th battery and ran circles around the competition

Yeah I just need a new charger and a couple more cables. All I lack is funds! Lol

However, at 21MPH your cart is running a bit slower than I calculate it should, so Scotty might be right about the motor being weak, or it might be something causing excessive mechanical drag.
I took it for a test run last night and set the program up to monitor the cart. I was maxing out at a hair over 4400 rpms and topping out at 21-22mph. The torque is amazing! I still need to play with the throttle linear adjustment or whatever it's called. I'm not sure if I saved the one Scottyb preloaded for me.

What does everyone suggest for a new motor? I would like a minimum of 25mph but closer to 30mph, some good torque, and the ability to run on 36 or 42 volts.
Price doesn't matter. I only want to buy one!

The motor RPM and cart speed numbers don't match the tire height and gear ratio, so either your tires are less than 23" tall or the speedometer you're using is reading low, or at least those are the two most likely explanations of the disparity.

There are no slip joints between the motor and tires, so with 23" tall tires, and stock (12.44:1) differential gears, the cart will travel at 24.2 MPH when the motor is spinning at 4,400 RPM.

Before looking at motors, I suggest finding out why the cart speed vs motor RPM numbers don't match and the reason why the cart's top speed is less than it ought to be.

Up the voltage - generally speaking, 36v is not going to move the cart as fast as you are looking to go.

These two statements seem to be a contradiction. It will be a lot cheaper to go 42-48v now and see what you got. Then buy a motor later.

You're correct. Price definitely matters. I guess what I'm saying is that I'd rather spend the money buying what I want the 1st time and not buying 3 motors to get what I want.

I've not measured the actual tire height so that could have something to do with it. I'm learning. Lol
