Default Add motor if adding controller?

I am Telling my dealer to that I was a little more top end speed versus the code3 (17mph). He wants to add a 500amp controller. It says it's not necessary to upgrade the motor. If I were to upgraded the motor, what can I expect to gain?

2. Series or sepex drive system?
3. What size tires are on the cart?
4. How many people ride on the cart?
5. Rear seat, cargo box, or small trailer?
6. Is the electrical system 36 or 48 volts?
7. What top speed is desired?
8. Is the used on or off the road?
9. Is the terrain hilly? If yes, steep or mild hills?
10. Is the footing sandy or muddy?

Dont know. I am going to assume it is Sepex after perusing through your site.

23x10xR12

4. How many people ride on the cart?
4-5. The 5th person is my 6 year old

5. Rear seat, cargo box, or small trailer?
Rear seat

6. Is the electrical system 36 or 48 volts?
48 Volts

7. What top speed is desired?
at least 24.
8. Is the used on or off the road?
90% on road

9. Is the terrain hilly? If yes, steep or mild hills?
Flat land(sea level), although I would like to take int the mountains on North Carolina from time to time, but that is only wishful thinking. i may tow a smoker with it for neighborhood functions.

10. Is the footing sandy or muddy?
We have black dirt here with some sand since we live on the coast. We may take it to the beach.

BBQ Boy, I just went through asking this on this forum and also talking to Dave at Revolution Golf Carts. The 500a controller will get you more torque and some speed. It can be used with the stock motor (has to be programmed for it) but will require the cables and solenoid to be upgraded as well. If yo go that route both ScottyB and Dave recommended the Admiral MOT 4 motor which should get you around 28mph, I believe. That's the setup I am looking at. My understanding is I would not see much of a difference between the 400a and 500a but the difference in price is not that much so probably worth just getting the 500a for the fan alone.

Couple of things.

Mathematically, removing the speed limit of the factory controller and running the stock motor to a safe maximum of 6000RPM will get you about 34MPH with those tires. Friction and aero losses might be hard for the stock motor to overcome all the way up there but I don't think speed is going to be your issue.

The 500A Alltrax XCT controller is a very stout and highly adjustable unit. It can be turned down to safely mate with the stock motor but still give you tire spinning acceleration and much improved top speed. If you decide to upgrade later, it can be turned up to its full potential. Curtis, Madjax/Navitas and others make great 500A controllers as well but none seem to have the user flexibility that the Alltrax does.

Absolutely must have 2AWG cables throughout and SHD400A solenoid.

If the dealer is a true CC dealer, he may not be willing to sell anything that goes faster than 20MPH (25 for a LSEV with lights, horn, etc) or it will no longer be considered a golf cart. This is something to ask. If so, the Alltrax will let you adjust top speed in seconds. The other brands, require expensive programmers.

A speed code 4 upgrade for about $100 could get you to about 22-23 with those tires if the dealer does not care about breaking the maximum golf cart speed rules. However, this does nothing for acceleration and torque which you will need a lot of with those conditions.

I was just told to stay away from Alltrax as it will pretty much crap out after 3 years. I then called my dealer and he said they won't carry alltrax any longer for that reason. This is where it becomes foggy. I don't know wether or not some dealers prefer certain brands due to better pricing for them, but my buddy was telling me his Alltrax failed hi twice. His lakehouse cart has a curtis with zero issues.

I have been an Alltrax Dealer for 10 years. In that time we have sold thousands of Alltrax Controllers from 3 generations of products including AXE/DCX to SPM & the new SR/XCT models. In that same time we have also sold 3 other major brands.
The failure rate in the Alltrax is lower than all the others combined. And this allows that the old Alltrax were easily killed by catastrophic motor failures, dropped wrenches, & mis-matched components.
The newest generation Alltrax XCT has 10 features you should consider before buying another controller. Go here > http://www.cartsunlimited.net/about-...ntrollers.html
Most importantly are the reverse polarity protection and the user friendly free interface software and water proof construction with built in cooling towers and fan
The 2 yr replacement warranty guarantees you get a good unit that will give many years of service.

I'm sure there are plenty of horror stories about failures but to me, the benefits of the Alltrax XCT outweigh the perceived risk. Without the ability to de-tune, a 500a controller from anyone else will absolutely require a new motor. No way the stock motor holds up to that kind of power and load for long.

Scotty sold me an alltrex 400 to go with my plum quick motor and my 2012 precedent has a top speed of 32 and with 4 person load stays around 27, plenty for me.

PS: listen to both of these guys, they really know their stuff...
