Default Motor vs Controller

What is the relationship between the controller vs a high speed motor when it comes to increasing speed. Will a controller speed up a stock club car, or is the motor necessary as well?

Are you asking about a sepex or series drive system? The results vary

For sepex clubcar, say 1510 or 1515 stock control. You'll likely only get another 5mph at most from upgrading only the control. This is also assuming you arent already running a speed code4.

The field mapping is what determines the RPM capability, and the stock control already runs that at 1.9~2A on the min field. 1268s have a lower limit of 2. Some obscure models I don't see often allow for 1A; potentially a bit faster. With the stock motor I would be afraid to run it any lower than 2...its risking damage at that point.

But a higher current control means more torque so you can start adjusting tire size and gearing for increased speed. However a motor change would be much easier and probably cheaper.

This topic has been discussed many times so you find more information by googling or searching the site. Basically sepex motor rpm is limited by stock controller. A controller upgrade can unchain a stock motor resulting in 22-23 mph on stock tires with improved acceleration. And offer additional options like shift on the fly performance modes while opening the door for any aftermarket motor.
Performance motors do consume more amperage than the stock motor. Assuming the motor is compatible wit the control, stock restrictions upon amperage flow and motor rpm may adversely effect the motors performance.

Others report good results with motor only upgrades on flat ground.

Trying to figure out if a 2012 club car can reach 25mph plus without a motor change by simply replacing the controller, or which one is less expensive. I just signed on to the site, so I have no reference to older posts.

My leaning is toward a PlumQuick motor swap with all stock components (have my disc brakes coming from you already). Just ignorant to weather this is the best rout to go.

Since you are in a coastal region you might get away with that. But I don't know how many mph you will actually see. My 24 mph mootr requires a 400a control which would give 22-23 mph by itself and a small tire increase could add 2mph more to get you there. But honestly 23mph feels fast in a cart to most of us.

Thanks for the reply. I have 22" tall tires and a 6" lift with heavy duty rear springs and everything else except the disc brakes is stock. I'll probably go with the Plumquick motor and 4 gage wires and go from there. Thanks again for the education...

Funny, that's what I had on the cart I just sold, 6" lift, 22" tires, all stock even the battery cables and I installed a Plum Quick Bandit motor. Real happy with the performance of it, tires at 28 PSI and on GPS, I could see speeds around 25-28 MPH. I'm starting to build another Precedent but I'm going to stretch it and most likely will go with a Plum Quick motor.
