Question about Controller vs motor upgrade

[MikeF0209]

I got a 2018 CC Precedent and I have a question.
If I want to achieve about 22-23 mph, would upgrading the motor be sufficient on this cart or do I have to upgrade the controller as well.

Is it standard to have to upgrade controllers when doing motor upgrades or can I keep the controller stock with an upgrade motor from plum quick for example.

Thanks,

I'm new to carts, but here's my take on it.
I have a stock 2003 48V with 10.3:1 rear axle gears.
It would do 19 mph downhill, 17-18 on flat and 14-16 on hills.
After installing a PQ Bandit it will hit 21-22 on the flat/downhill and 15-17 on hills.
I got the Bandit because I figured the motor was 17 years old and wanted a known good condition motor.
Been prepping/modifying for an Alltrax XCT 48400 controller.
Cables/wiring are almost done, solenoid next, then the Alltrax.
I think ours would go a little faster than most stock carts because with the gear ratio & 18.5" tires it is equal to having 22" tires and 12.0:1 gears.
Just a motor upgrade with a stock system might get you to 20 mph or just over, don't know.
I think a controller will get you there, maybe with a stock motor.
I think other more knowledgeable people will have input.
An upgrade to a 400A controller would need to include 2 ga cables for the batteries/motor and a 400A solenoid to handle the increased amps.

I have a 2016 Precedent, with an Alltrax controller and 2 gauge cables, I can hit 27 with the stock motor on 22” tires.

Your starting point for any speed upgrades would be the controller. The controller is the equivalent of the carburetor on a electric car. The controller governs the speed. Even with the most powerful motor built will only go 19.6mph with a Curtis stock Controller. You also need to provide field mapping for a new motor. To me the ideal situation would be to upgrade the controller first to see how it goes. If you got lots of hills in your area you may find you need to increase your hp. If you need more speed get a speed motor. If you need more low end power get a torque motor.There are a few controllers out there but my preference is the Alltrax XCT48500 which is fully user adjustable.
