Re: 1987 Porsche 944 S conversion

I would take a look at SendCutSend.com for those aluminum pieces. I use them for quite a bit of my custom fab stuff that I want to *not* look like I made it with pliers and a dull hacksaw.
If you have that many to make....automate it for sure.

Passenger floor pan removed, new floor pan loosely fitted. Should get me through another 40 years.

Re: Tesla Battery Boxes

Isaac....that was hilarious. I'm pretty sure it will be alright, and until the shop actually gets the engine bay cleared out, this is all theoretical, but I don't want to come at this without exploring all options. 16 Tesla cells is a bit of a challenge to keep as low and centered as possible. But f...

Tesla Battery Boxes

I'm designing my battery boxes, and I have seen the Tesla model s cells laid both horizontally as they come in the Tesla, and I have seen them standing on end. Does anyone have any real world experience with standing them on end, and if there is any impact at all from a cooling perspective, or packa...

Canbus Termination Question

Hi,
I looked through the wiki, but didn't see anything on this.

Is the canbus terminated on the inverter controller? I'm wondering if that might be the problem I am having reading any values from it.

Alrighty then....$20 Amazon gift card to the first person who can accurately help me source these little buggers for use on my project.
This is driving my crazy, and I'm 90% sure these are available off the shelf somewhere.

I'm considering making my own HV to HVJB cables for the Tesla LDU, but I have no idea where I can source the cable seals pictured here. Anyone have a clue what these are called or where to buy them?

Re: Rolls Royce with a Tesla Drivetrain

Got the motor on the stand, swapped the board, plugged in the wiring harness, got precharge contactor behavior as it should be, logged in to wifi and saw the web page.

Not a bad days work.

Re: Rolls Royce with a Tesla Drivetrain

Have you a plan for the hydraulics? Brake and ride height system run off cam-driven pumps, and it’s a specific fluid, so can’t easily replicate. There’s a good overview here (https://www.rrsilvershadow.com/Emenu/hydr.htm) I think if you did put a full Tesla battery pack in the car, it might be the ...

Re: Rolls Royce with a Tesla Drivetrain

Sorry, I was unclear there. I didnt mean I was going to literally use the Tesla pack itself, but that I would be purchasing a full set of the 16 or so batteries that the Tesla comes with, and using them to build my own custom pack.

Apologies.

Someone had to do it, so I guess I'll be the idiot to pull it off.
[*]One perfectly good 78 Silver Wraith (check)
[*]One brand new Tesla Sport LDU (check)
[*]One fabulously designed open sourced control board (check)

What could possibly go wrong?
