overdrive pulley...hadnt thought of that. im curious as to what gains might be seen.

well, you'd generally hit your peak amperage output at a lower RPM... so Instead of hitting max amps at say 2000-2500rpms... you might it hit at 1500. Alts aren't like computers... you can't overclock them to get more power... you max out at a certain rpm and thats it.... more rpms doesn't do anything.

Electronically speaking.... it would be better for somebody who did a lot of driving at low RPM's.... maybe a city driver... or somebody that drives a lot of 40mph in 5th gear.

I'd be cautious of doing this though, not sure if this would cause the alt to burn out quicker..... or even if the bearings inside of it would heat up too much and seize up. No clue if either of these issues would even be a problem or not... but its something that I wouldn't be surprised if it did happen.

I think the best solution for you.... if it were easy to do (which I'm sure it isn't) would be to mod the alt to output 15v instead of 14.xx. The higher the voltage the less amperage needed... the less amps needed, the less resistance, heat loss, and voltage drop.

Someday cars will run on 36v or higher systems... that day will be the single greatest day in car audio... 2000watt systems will be able to ditch expensive 1/0awg power cable and run stuff more like 4awg or even 8awg instead. Amplifierss will draw 30 amps instead of 100. I pray they have those higher voltage cars out by the time I go buy my next car.
