Torque loss estimate switching to high speed gears
Title says it all. Looking for an estimate in torque loss if I switch to 6:1 gears
2005 TXT, Series, 36v, lithium upgrade, stock motor and controller (plan on sr48500 as next upgrade before sending motor to plum quick!) All my driving is flat pavement around the neighborhood I’m hoping to switch gears upgrade the motor controller and still gain torque at the end of it all! Thanks guys Sent from my iPhone using Tapatalk |

Re: Torque loss estimate switching to high speed gears
6:1 gears are 50+% taller than stock gears. Expect at least that much torque (power) loss.

Re: Torque loss estimate switching to high speed gears
How fast are you running now, and how fast are you looking at going? If you are just using the cart on flat pavement as a neighborhood cruiser, then maybe consider a Series to PDS conversion.

Re: Torque loss estimate switching to high speed gears
Running about 16mph right now and looking to top out north of 30 eventually. I want to be able to drive on more major streets without feeling like a jackass holding up traffic.
Probably not going to convert but interested in what you think the results would be and what is involved in it. Sent from my iPhone using Tapatalk |

Would the 500amp controller counter most or all the loss? Sent from my iPhone using Tapatalk |

Re: Torque loss estimate switching to high speed gears
It will certainly help but, with the stock motor, not entirely.
There are too many variables for a simple answer. Have you ever been in a golf cart over 30 mph? It's pretty scary. The suspension & steering geometry is designed for 14-19 mph. The braking is no where near adequate. |

Need to replace the Controller and motor (I recommend Scotty's FSIP MOT-B3). Need a F&R switch and a PDS wire harness. Existing controller and motor can be sold to offset the cost. |
