Anywho, made room for the motor today..



Will have to eventually make a bracket for the power steering pump, but plenty of room now.
Now I'm confused. Your PS pump seems to still be attached....and is that a Leinenkugel sitting near the firewall? I thought I was the only fool to drink and work on my cars! Sometimes it helps when working on a particularly frustrating bit.

Belt path 1:

Simpler:

On this option, are you replacing the p/s to gen belt with a longer one? The pic isn't quite clear on that point. I wouldn't worry about slippage if you use a large enough pulley on the electric motor.

Have you sorted the AC2 to crankshaft ratio yet? ie, how fast will the electric motor spin compared to the crankshaft?

Something Ben Nelson mentioned to me is if it's possible to disengage the electric motor from the crankshaft, it would be beneficial, and make the brushes last longer. One possible scenario is the battery pack is depleted and you don't want to waste the fuel spinning a now useless motor. If you had an a/c clutch on the electric motor, you could do just that from inside the car. And the pulley on the a/c clutch would I think be close to the best ratio for what you're doing.
