I built a cart for my Fire Dept and we needed a little more power. We were torn between doing high speed gears or installing a Plum Quick Bandit motor. Our cart is a completely stock 2001 48 volt Club car. We decided on the motor due to the possibility of loosing to much torque with the high speed gears. So I made a few videos that show the results of installing the bandit. Here is two links to You tube first one is with the stock motor.
