so the only things you would have to know wound be your carts actual top speed, the actual mounted tire diameter, and the gear ration of your differential. |

Re: RPM
If your tires are truly 22" tall, and you have stock differential gears (12.44:1), your motor spins roughly 190.1 RPM per MPH.
IE: At 15.0 MPH the motor is turning at about 2851 RPM. BTW, you'll have to physically measure the tire height, since the numbers stamped on the sidewall can be over a inch off. |

Re: RPM
well somehow, here on this site, I got a copy of it in EXCEL......and I was pretty sure it came from you, lol if he had given us that specific info.....I would have just "plugged and chugged" the numbers for him.

Re: RPM
Increase the operating voltage. The stock 36v motor will produce 33% higher RPM on 48v.

Re: RPM
He said "get the rpms" rather than "get the rpms up"
But it is a moot point since both guesses at what was being asked was answered. |

Re: RPM
yeah I just wanna see what rmp's im running well I know my tires aren't a true 22 so I am taken a guess here since they are worn down I say they are a 20 and my top speed seems to be 18 and like 19 down a small down hill.

At 19 MPH on 20" tires, the motor is spinning about 3,972 RPM. FWIW: My Carlisle Turf-Master tires say 18x8.50-8 on the sidewall. On their website, Carlisle says the MTD (Mounted Tire Diameter) is 18.3". I measured the distance the cart traveled in four tire revolutions with me on it, did the math and came up with a tire height just over 17" I also get just over 17" using a level and a yardstick. |

Can you post a current calibration certificate for that yardstick? |
