2107 Motor upgrade options

[jayhrc51]

I've been looking into motor upgrades and I wanted to see if there is anything that I'm missing before dropping some money. Carts Unlimited has what seems like a nice option for under $600 with their FSIP speed motor. I just recently purchased an Alltrax 400 amp controller and upgraded solenoid from them so, according to their site, I should get around 27mph with factory wheels on their motor.

Are there other options that I should be considering that will get me similar speed. What about Plum Quick motors or anything else? Trying to stay in that $600'ish price range for motor budget but willing to up it to $750 if performance gains justify the extra spend.

My cart is basically street only and I don't have anything that I would consider a steep hill near me in the FL panhandle. I will be upgrading all wires to at least 2 gauge when I do the motor. I also plan a 3" lift and some 23" tires. Any idea what speeds I should expect with all upgrades combined. I'm sure that I'm not the first to have a similar setup so what are others seeing? Is 30mph realistic?

I have a 2011 Yamaha with the XCT400 controller and I upgraded to a double banded speed motor from Electrical Motor Products. The cart is otherwise stock, and I hit 30 on the nose via gps app on iPhone. With your eventual lift and bigger tires you should easily exceed 30 with good batteries. I called EMP and explained exactly what setup I have and terrain, # of passengers, etc. and they hooked me up.

Spend cheap, get cheap.. simple as that. You know the old saying, "if it sounds too good to be true........"

Dont spend a dime "upgrading" your stock hitachi motor, it didnt do well at its "stock 19mph job", upgrades are pointless on the stock motor. (Your hitachi may not do 19 if the controller isnt unlocked, but still, dont pay any motor place to "redo it for more speed"). Ptv speed code (on the original motor controller) is the best for stock motor, any $ beyond that is a waste.

I sent my stock Hitachi motor to Plumquick for the Bandit upgrade and went from 12 to 17mph. I then added a Alltrax XCT 300 and got to 21mph. Unfortunately, it failed after two years and then I found a deal on a D&D motor.

I would call Don Plowman at Plowman's carts and discuss motor options with him. He hasdesigned motors specifically for torque and/or speed and is very helpful.

When I say upgrade, I mean replacement for something better. I prefer a purpose built motor but asked about Plum Quick or other options because I'm not up to speed on all the different motor options yet. I am definitely a "buy once, cry once" type of guy. So, what kind of options should I be looking at?

If I swap out the motor does it make sense to also change the rear end gear to something like a 10:1. Thought process being that I might be able to pick up more speed while reducing overall engine RPM. I realize that would also impact the torque requirements on the motor but just trying to get a handle on what makes sense and what is a waste of energy (money).

Any gear change should be accompanied by a controller upgrade. And, only specific motors will work with the stock controller (which isnt very powerful at all).

I've recently installed an XCT 400 and a HD solenoid so I'm ready for more upgrades at this point. Are you saying that a gear change should be the next logical step in the upgrade progression? I was thinking motor (since I've already done the controller/solenoid), wheels/tires/lift and then gear as a final piece of the puzzle.

If I do the gear change before motor that actually works in my favor because it'll save me a little bit of cash on this next round of upgrades.

If you change gears and keep the stock motor & controller, you will shorten the life of both. I dont think gears should be on your upgrade list at all.

I do not have a stock controller, I have an XCT 400 from Alltrax.

Your next step for speed should be ditching the stock motor.
