Performance Questions
I have a 2007 CC Precedent. Upgrades to date are... Plum Quick Bandit motor - I was getting 25 mph on flat ground with stock tires and 4-12 marine batteries (in cart when i got it). The batteries did not last long so I replaced with the CC conversion and 6-8v Trojan t-875s. Very pleased with the conversion and the batteries. At the same time, I put on a Jakes 3" lift and 21" tires. To my surprise I lost about 3 miles per hour. After giving it a lot of thought, I think the loss of speed was due to the added weight of the batteries. I would like to pick up more torque and if possible gain a little of that speed back. What changes would you suggest? At this point, everything about the drive system is stock except for the Plum Quick Bandit motor.

Re: Performance Questions
A bigger speed controller will allow the motor to access more amperage for more torque. 2g cables will allow that amperage to flow unimpeded

Also... I assume the changes you mention will shorten run time? If so, by how much? What controller would you recommend and how much $ would I be looking at for the controller and cable upgrade? |

Re: Performance Questions
I have a dcx 500 with high speed/torque motor and wind will not phase, small hills will not slow it down either.
You should notice a big improvement. As far as runtime, I think it depens on how you use your cart. I use mine for golf exclusively, and I can get 36 plus holes in with no problem. I am using the stock 6g cables with no problem. Dcx 500 is around $400-550. |

Re: Performance Questions
IMO even withthe increased weight of the 2 extra batteries going from 4-6 adding 21" tires should have gained you MPH not lost. 2 batteries is not enough weight IMO to slow it down so much. Maybe the tires are not infalted properly and are causing more drag esp if they are All terrain. Still i think something is amiss. make sure you are getting the right voltage from all 6 of your batteries.

Tire inflation is as suggested on the street tires. The weight difference in the 4 vs. 6 batteries is a total of 204 pounds. The marine batteries in the cart only weighed 45 pounds each while the Trojans weigh 64. As far as the 3" lift goes... I have noticed the cart drifting some from side to side when at high speeds. Any ideas on this. I thought I may have left the front axle nuts too loose, although I thought I tightened finger tight and then backed off until I had a slot for the cotter pin. |

Re: Performance Questions
Is that what the lift instructions said? I don't remember seeing anything on that when I put my lift on, so I wasn't sure if they should be forced to the next slot, or left a slight bit loose.

Re: Performance Questions
I don't remember seeing that part in the instructions. That is just the way I have always done it with other equipment. Typically if you force them to the next slot you will create friction on the bearings.

i know you are getting slighty more wind drag with a lifted cart though as more cart including tires exposed to wind in front. But at such low speeds i just cant see that being the issue. Are you usign a speedo or a GPS? |
