Furthermore you're the dolt that decided to come in and light up my post over at golf cart modified with a completely false statement. As far as meeting up I'm closer than you think... ;) Further still I don't have any roll back issues because I have the Navitas controller which mitigates the parking brake test rollback so yes gears are not a problem. Lastly 75v is not overvolting anything. The curtis and the navitas can handle 72 without issue. To say nothing of many new carts also being 72v. |

Re: What is your Top Speed (GPS verified only)
58v lithium pack. Stock gears. Stock TXT48 motor. 23" tires, 6" lift, HD rear springs. Alltrax 300 controller.
I had the controller RPM limited to 5800 and it hit 29 to 30mph on GPS. It was really not fun at that speed. I changed the controller to limit to 5650 rpm as I want 28 to be my max, but I have no re-GPSed it since I reduced max RPM yesterday. |

Re: What is your Top Speed (GPS verified only)
Old 04 PDS with new Navitas package with Blue tooth stock gears 23" tires. 38 MPH and will pull the front tires off the ground when I set the acceleration to max. Nothing new here guy's voltage = power & speed!
In fact I'm surprised that you aren't faster than that @ 72 volts! My old 72 volt cart ran 60MPH and it was DC with a Plum Quick motor & gears and it would ride about 20 feet on the back wheels when I wanted it to! |

Re: What is your Top Speed (GPS verified only)
Wow! This escalated very quickly. I was coming to comment that there are already multiple threads started on the forum that asks what everyone's top speed is and list their mods... but please carry on
BTW if you guys decide to meet up to "settle this", please record it and post back to this thread. |

It'd be cool to figure out why some carts are more comfortable at high speed than others, if anyone has any guesses or insight; this could be a good resource for others building fast carts. side note- I've got Leaf cells arriving today and should have them installed in a couple weeks, we'll see if I get any more speed out of the extra voltage. I currently have my controller tuned down a bit, I think I set it near 500a because the batteries and cables get extremely hot when running the full 600a for a couple miles at near wide open. Also, the batteries get GASSED if I floor it; I find I can maintain near the same top speeds using about ¾ throttle the way I have it set up, and it adds about 2 miles of range to driving it that way. |

Re: What is your Top Speed (GPS verified only)
Stock rear end with D&D motor 400amp 48 volt Altrax controller. Tires are low profile don't know the size and it's pouring down raining so I'm not going out to see, and it does 28/30MPH on flat ground and can take a turn at speed with no issues.
I like a little more side wall on the rear tires to make them a bit taller. |
