Do you think that your accessory belt can transmit that much power?

What you're thinking of doing is quite similar to Brucey's hybrid setup except he used a low voltage AC motor setup. His gains were alright. I expect yours to be better because of the lean burn engine. If you can get it to keep you in lean burn all the time you should see a decent gain.

It would be much better if you could seperate the motor from the engine though. I was just talking to Ben Nelson last night about this. I think a series wound or PM motor off of the 2nd transmission shaft (not the input shaft) of a manual transmission would work much better because it would allow you go full EV. My idea also incorperated a freewheeling clutch to eliminate brush wear when the motor isn't in use. The downside is that you don't have a transmission to assist with an additional gear reduction. But, when talking with Ben, he normally drives his Metro in 3rd gear which is nearly a 1:1 ratio.
