I love a well-documented project.
I'm converting the little brother to your C3, a blend of 1970 and 1972 Opel GTs. Poor man's C3 I suppose.

I went over to your thread on the Corvette forum. Yep, same BS I got on my Opel GT forum. Lots of ignorance of people who have no clue about what an EV is (some deliberate and some innocent), a handful of people condemning you for what you're doing to your own property because there are correct and incorrect opinions to have about cars apparently, and a mostly supportive group of people just happy that you're passionate for project and sharing it with the world.
Your car looks fantastic. I've been looking at GTs so much, I forgot how much I love the comparatively steroided-up look to the C3's. Looks stellar and sinister in black.
There were a pair of C3 conversations happening here in the last year, seem to have fizzled out, haven't seen updates in a long time.
A few notes...
- You're avoiding the Model 3 drivetrain. Damien's already got his spinning, he usually sinks his teeth in until he's got a success. He piggybacks on Johannes' Open Inverter software, which works pretty much universally, so, once he's reverse engineered the Model 3, it's pretty much just waiting to go. It's not that many wires. It's a 6-pole (3 paired) resolver, that was his last stumbling block, and then 3 power leads. The motors are dead simple.
You don't have to use the inverter there to drive the motor. You can use any inverter, as demonstrated by him using the Prius Gen 3. This week's news about the Prius Gen 3 inverter, Damien discovered just the MG2 inverter alone will handle 500 amps before gracefully shutting down. The Gen 2 did about 70% on the MG1 as its MG2, so, you could realistically see 850 Amps out of an inverter you can often pick up for around a hundred bucks. Just ludicrous value for engineering and hardware.
- I would not use the fancy expensive controller you're planning. I think every single Tesla controller sold is based on Johannes' Open Inverter open source project, they just print and rebrand their own boards. You don't get any support beyond using the forums to help troubleshoot, but it's like 1/10th the price.
- You're worried about suspension. Why not just grab the whole suspension from the Model S or Model 3 or whatever you're going to use, and adopt it wholesale? Only issue might be width, Teslas are fat cars, but, if you want it low with wide flares, no problemo.
Sounds like you've got this all pretty well researched. I'm guessing with you having lost your job recently that this has become a bit more of a budget build, so, maybe some of those are corners you want to cut.
I was on the fence about you whittling a coffee table into a toothpick, taking a running, modded 'Vette when there's gotta be some aborted projects around for cheaper and easier. But, I like your idea of just driving it first for a year. It'll get you nice appreciation for the old, and a good comparison to what it became.
Keep us all updated, would love to see regular updates.
