1988 ezgo new motor

[1988ezgo]

Hi I have a 1988 ezgo resistor cart and looking to get a little more speed without sacrificing torque. I've been looking at motors and would like your opinion on one. Here is one i've been looking at it's 4 hp @ 4400 rpm. Not sure if this is just for speed or will help torque a little. Thanks http://www.blockbustergolfcarts.com/...plined297.aspx

if you go with a more powerful motor the chances are real good your gonna melt your resistor coils...............

[1988ezgo]

Is there some way to stop that?

[rabbitreborn]

upgrade to a solid state controller.

[1988ezgo]

But why would it melt the resistors? It still has the same amount of power and all I wouldn't be upping the voltage. And what all would I need to upgrade to the controller?

[rabbitreborn]

because a bigger motor is going to demand more power.......

as for what all you need, talk to ScottyB, he has complete kits for doing these upgrades.

I own the motor you are referring to (also known as a D-297). It is a good motor and performs as advertised in my (solid state)TXT. This cart already had a 400amp speed controller in it and to reap the benefits of the motor I had to upgrade the cabling and the F/R switch. Pushes the (relatively heavy) cart to 20mph with no heat issues.
I also own a 1991 resister cart. I put the motor that was in the TXT in it. This is a 2.5 hp 3400 rpm(approx.) motor. Well, it really lit that resister cart up, pushing it a full 3 mph faster on the flats and up my test hill. BUT, I say again BUT, not long after installing this motor I had to replace two contact studs and the wiper contact(switch) on the speed board. May have been coincidence (parts were 20 years old) but I also have some mild heat issues now. Driveability is also affected. The cart lurches more when operating at other than WOT. This is with only a slight increase in power (2.5hp vs the original 2.0hp). Based on my experience I would think the D297 would completely overwhelm the resister type electronics and would also be annoying to drive except at WOT. These motors draw a lot more amps than the resister electronics can deliver resulting in failure of the speed board, resister coils, F/R switch or all of the above.

Also: If you are serious about buying this motor I got mine from a site sponsor much cheaper than what you referenced.

you can have your motor done for 1/2 of what they want for that one you linked to...but again you have to upgrade the rest.......................

Is there any solid state conversion kit that you can buy somewhere?

[scottyb]

I sell a conversion kit. Unfortunately, some key components have become unavailable due to a company being sold ... We are working hard at reproducing these components ourselves. Please check with me in a week or 2
