Cool - thanks for the numbers, CyrusCosmo!
I'm glad my response didn't bug you; often people don't talk about it, you just notice a lack of enthusiasm or participation. I certainly don't want to get into a "my tool is bigger" contest, especially with the tools I have...
When I first started thinking about this, the AC Propulsion motor was about the only high performance AC option. It was way out of my budget, so I spent some serious time looking into small, efficient trannies that would work. Unfortunately, everything I found was "custom" and expensive as well. The options available now - batteries, motors, trannies, etc - make this really fun!
I'll put together a spreadsheet with some form of combined output torque and speed graph. I'm really curious to see how this will work out. Oh yeah, would you have weight #'s for the C4 and a scoobie diff? It seems it would be good to compare the system performance.
