need for speed

Right now i have a 36v cc resistor cart named Purple Nurple.I'd like to see 50 mph so was wondering if it would be better to start anew or if there was a way to upgrade? Pretty much my main question is, is there anyone who can give me help or ideas for a 50 mph cart build?
Thanks, Ratchet

are you on a budget? do you have a tool box? motor,controller,h/d solenoid,batteries,wires,brakes,rear gears,traction control, and a seat belt is always a good idea at 50 mph. i built a 2006 ezgo with a d and d motor and programable controller with all the above, we are cranking it out around 50 mph.just a sunday driver. i also built a 72 volt thats runs about 65 to 70 mph. that one we take out and hope we make it back in all together. ''it's fun'' . the speed your looking for is not cheap. like every thing you start making it do things it's not made to do it going to cost you. good luck it crazy at this speed

Theoretically if you used your 36v motor, put in 8:1 rear axle gears, added a 500 amp controller, 2ga cables, 23" tires and ran it on 72v (6x12v) it should run about 48 MPH.
The motor should handle 8000 rpm but being that old it may still come apart.
That being said your motor will spin about 5600 rpm and you would have to think of some way to steer it that that speed. You will also have to add hydraulic brakes to stop it.
Guessing the cost for the project to be about $2500 or more.

Thanks for the suggestions.So a 36 volt motor can hold up to 72 volts?Or is it better to go with a 72 volt motor and controller? Also have heard some stuff about AC motors.

It all depends on what your budget is.
The 36v motor will spin twice as fast as a 72v motor which will give you the speed.
You may have to upgrade the motor but I would still keep it at 36v.
Series motor speed is controlled by the voltage you apply to it and only limited by the RPMs. Most motors will safely spin up to 8000 RPM but the faster they spin, the more trouble they can be.
You would need a 72v controller.
IMO AC systems will become the best system for a golf cart and if your budget allows, I would look into them.
