This bus looks so good in person. Excited for this project
in reply to: JJ’s Class 11 Oval #81157These tires look like what’s on an RC car. They’re going to rip!!
in reply to: Dans ‘65 Tesla #81156This project is going to be kickass. We’ve got a lot of wiring in our future. I’ve got a couple ideas on cool things we could do with this to push it to the next level

Grave robbers 🪦in reply to: Dans ‘65 Tesla #80988Hey John. Looking to get out there soon. I’m in Kentucky for the next couple weeks but may be able to swing by this weekend and next to start to work on this. Call me and we can discuss
in reply to: Dans ‘65 Tesla #80710So looking online this motor a capable of producing 600NM.
With EVs, the drive motors are typically direct drive. A peak torque of 600Nm at the motor is large, but at the wheel is actually not that big, so you’ll need some additional gear reduction to get going. After 9.73:1, that puts mathematical torque at over 5800 Nm 😎 and that’s actually pretty normal for wheel torque with an EV.
This motor controller is just using the existing control board, so it shouldn’t be limiting its output. I’m betting that we’ll need to dial in the power a bit to somewhere that will allow us to put it down given the lower weight of the bug.
in reply to: Dans ‘65 Tesla #79958Looking good! Here’s a general list of things to consider:
- Battery management system (BMS) – do you have one yet? This measures the voltages of all the cells in the battery pack and keeps them at an even level. You will need to run wires from each battery module back to the BMS.
- Contactors and fuses – you will need a contactor to switch the HV energy off between the battery and the drive unit. These need to be kept in a Water/dust proof box.
- Cooling system – The drive unit will need to have some coolant cycling in it to function. You will need a small radiator and reservoir tank. Batteries can be kept air-cooled but would be better with some type of cooling.
- Motor controls – You will need an electric accelerator pedal, a CAN display screen where you can select drive modes, CAN harnesses. For the small tesla drive unit, we had to buy a new control board because the controls are locked to the VIN of the vehicle it came out of. I don’t know whether the large motors have been successfully “hacked” where you can control it without needing a new control board.
- Charging – you will need a J1772 outlet mounted somewhere and a charge controller. The charge controller will need to be wired to your BMS and your battery.
- Safety –
- Insulation is always important. Get high voltage safe gloves for attaching the battery modules in series.
- Do not work on the battery alone. Have a second person present when wiring up the battery.
in reply to: on Craigslist…… #77924Those Westy tents have definitely gone up in value. Hard to beat them in terms of style and usability for camping though.
in reply to: BrownCloud KCW baja race team #77320Congrats Cole and team! What an accomplishment!
in reply to: Glenn's Weekend Blue 1963 Ragtop #76979Been out of commission for about 3 months, but finally got the bug back! I had them weld in the rear bumper metal and mount the bumper for me. Super excited to have it back. Got lots of thumbs up and made lots more smile just on the way home
in reply to: KCW randomness #76978Found this crazy old picture on the internet today
in reply to: Buses By the Bridge #73018Moss crew made it to San Diego. Camping here in the rain tonight. Here are some more photos from BBB
in reply to: KCW randomness #72106check out this crazy bug build
in reply to: Jason's Projects #70986Is the show tomorrow Jason? Look for Michael Bream and the EVWest guys they’re gonna be there
