Want to build a 35 MPH cart
OK guys, I thinking on what it would take to build a 35 MPH max cart for use on county roads? I would use it to run around to the store, post office, etc. My next door neighbor is a CHP and will get me the check list for street legal.

Re: Want to build a 35 MPH cart
36v series cart converted to 48v, 8:1 gears, 700 amp controller, HD switch and solenoid should do it.
You mentioned CHP, if you're in California it will be hard to get your cart street legal without a real VIN number. |

Re: Want to build a 35 MPH cart
At 35 MPH can you get up to 30 minutes of battery pack life?

Re: Want to build a 35 MPH cart
If I understand, a stock series motor is 2850 rpm @ 36v. 48v gives +25%, that would be 3500 rpm. Calculator gives that 24.1 mph with 18.5" tires. Am I correct that it would take a 27" tire for 35 mph?

I posted incorrectly before, add 6:1 gears and on 18.5" tires your speed would be 34.9mph. That being said, it is doubtful that a stock motor with 6:1 gears would have enough torque to get up to that speed. The tire size increase would do the same as an axle ratio change and the torque would still be a problem. |

Re: Want to build a 35 MPH cart
I know that to voltage increase is 33%. I heard form Scottyb that the increase in speed and torque was about 25% with the 36v to 48v conversion. Are you saying that the increase is linear?

Scotty's 25% number is a non-scientific, seat of the pants, practical experience, realistic number that is probably more accurate. |

Re: Want to build a 35 MPH cart
And what about the stock breaks at that speed?

Re: Want to build a 35 MPH cart
Stock brakes are VERY ineffective at high speeds. They are designed to stop the cart with 2 passengers at 14mph and not much more. The kind of cart you are talking about needs MANY SAFETY improvements. Brakes being one of them.
