WOW It's really that hard on the axels?
You wouldn't by chance have any pictures would ya?

WOW It's really that hard on the axels?Sorry, I transfered it all to others when I hung up my wrenches, retired, and moved away from Alabama.
In answer to your question, yes it can be done. We have done it.
You will need a bigger drive motor, much more robust drive controller, and you can cut the 'life expectancy' of trans axle to 75% less than normal .
No pics, they were other people's toys.WOW It's really that hard on the axels?

LMAO Yeah I get that. I always thought I'd blow the 10 bolt rear in my 79 Z28 pulling 1.19 second 60 foot's every week at the track. Then I did a full nitrous pass ONCE with a 1.11 second 60 foot and 8.73 @ 177 in the quarter mile. That was my best time ever. Not to shabby for a backyard built car in the early 90's.No pics, they were other people's toys.
Yes, if you pour 4 times the horsepower+ into the final drive than it was designed for, it doesn't live that long.
Yeah, we all have to 'throttle down' some day .LMAO Yeah I get that. I always thought I'd blow the 10 bolt rear in my 79 Z28 pulling 1.19 second 60 foot's every week at the track.

Nah they don't want to upset my other daughter they have to work with her in the common wealth attorneys office. lmao"I'M TELLIN' YA, SON, YER GONNA DRIVE ME TO DRINKIN'... IF YA KEEP ON DRIVIN' THAT HOT... ROD... ER... GOLF CART!!!"
P.S. What did ya do, slip the deputy a fifty while nobody else was looking?
Y'all might want to check out my Youtube playlist. lots of good stuff here. About 180-190 songs
Didn't I post the picture here what the higher torque of higher voltage did to the rear leaf springs? They looked like wet noodles! The new heavy duty springs are working great. Though I have to admit I don't think I've stomped on it like that since bending the first set of springs. lolDiesel and electric motors are fairly close in that their torque is high starting at low rpm's, I mention this because when I was working for the local school district they had a John Deere diesel zero turn mower with a Hydromatic transmission that really multiplies the torque and from hard shifting from forward to reverse twisted the axles in half at the spline that goes into the differential and those axles were very heavy duty. A larger high torque motor will likely break a GC differential fairly easy.
Yes. Torque-related fatigue-failures are real.Diesel and electric motors are fairly close in that their torque is high starting at low rpm's, I mention this because when I was working for the local school district they had a John Deere diesel zero turn mower with a Hydromatic transmission that really multiplies the torque and from hard shifting from forward to reverse twisted the axles in half at the spline that goes into the differential and those axles were very heavy duty.

Pulled this old post up from July 4th to see just how long the battery has been installed. Roughly 3 months and with the solar panel doing most of the regular charging duties. I checked the BMS yesterday to see how many cycles the battery has had now at a little over three months of use. 15 cycles is all in about 90 days. I think that is just way to cool. Looking like this battery may well last me the rest of my lifetime!Finally put the LifePO4 battery in today. Holy Smokes alive! Stupid quick is the only thought I can come up with for it. If you can imagine getting axel hop in a golf cart then you know what it feels like. Loosing 260-270 pounds and adding about 7 volts under full load really was a game changer. I'm actually a little afraid to mash it straight out anywhere it might get traction. Can not wait to get some taller SOFTER tires. It rides even rougher with the weight loss. Also looking forward to switching it over to a newer type system some time down the road. It would be nice to be able to run a lot slower without all the heat waste this one has. Went almost exactly 8 miles down logging roads and still had 71% state of charge when I got back. The new systems with regen motor braking would be a lot, maybe even twice as efficient as the current system.
Don't know about that setup. I believe those are for a gas engine go-cart with a centrifugal clutch and not an electric golf cart.@Supervisor42
You said you had done some carts with CVT's and electric motors how much of a beach was it?

They are meant for gas engines but I have done a lot of crazy crap like this in my time. I believe I can use one of those and swap the rear gears to 6:1 and have 50% more torque off the line and twice the top end speed.Don't know about that setup.

Most of what we did was upgrade the motor (bigger), the controller to SEM or AC, and boost the battery voltage.
You already did that for me in post #159.@Supervisor42 If you have the time and feel like it give my idea some thought and pick holes in it for me, tell me why it won't work. Please
It will require some fabrication but that's life in the fast lane. lmao
