650amp alltrax, emp motor, 48v, 2awg cables, 20.5" tires=what speeds?
Stock height ezgo txt series cart. I found all this stuff for cheap. If it all works right, what kind of speed and torque can I expect? Will it chirp the tires, possible wheelie, any ideas on speed?
650 amp axe alltrax controller 2 stage emp motor 36v 6, 8v batteries for 48v Upgrade cables to 2awg Heavy duty f/r 215/50/12 tires for 20.5 inches on stock height. I'm possible thinking about a small lift to get 22" street/turf tires, would it make a noticeable difference? I'm trying to get to 30mph. Is it possible with this setup? . |

Stay under 6500 RPM. 12.44 gear ratio is stock. Max is 32 MPH. Im not a cart guru so take it for what its worth. |

Call and talk to EMP about what speeds you want and they'll fix you up but you might need 8:1 gears.

You guessed it. The build is done and it is fast! I don't have any completly flat land around my house, but I hit 33mph on a very slight downhill slope. It will cruise easily at 20-25mph. |

Huge difference. It doesn't burn out or do wheelies but it takes off fast. It leaves our gas one in the dust. It's wired for speed not torque though. If the controller was set up for torque and the motor wired for torque it probably could pop a small wheelie. I have the switch for it. I may end up wiring it to be switchable for speed/torque. It'll just take a lot of cable to run it up to the front of the batteries. |

I have similar setup, D&D High Speed motor, 6:1 gear, 500 amp controller, same size wheels and tires, 48v and don't have a street long enough in my neigbhorhood to top it out. I've hit 35 (gps) before lifting off!
