Playing with an under drive pulley would throw off some of the benefits of a lower field coil current. There might be some gains to be had though. Its not something thats going to be a straight forward adjustment.
Aw, sorry to hear. What driver and FETs were you using? Mind sharing the schematic? I think a Denso square conductor alternator (~20% higher fill factor) and synchronous rectifier could return a reasonable 70% efficiency which is not too bad.

Yea I realize that, but it's not like reducing load at idle saves much fuel anyways, and even a small reduction in the speed of the alternator and water pump helps a lot for power savings under typical usage and high rpm since power is a cubic function of speed.
