Just a thought - if you spin the alt faster, it will make more current - correct? it is an induction device after all. So, would it be possible to put a smaller pulley on a stock one so that it would spin faster?

I guess even if this is possible, I still wonder how much more current you would get from such a modification. And I don't have a clue if it's safe to do or not.

I believe the pulley set I put on was a smaller alt pulley than before, but still not enough power, especially not when I want to run 4-8 100w lights.... plus my system, plus my efan, then I still need sufficient power to the rest of my truck to run right.........

From what I have seen 200amp is the largest you can run to be safe with stock wiring, even seen that the power wire to alt needs to be upgraded though with the new alternator.........

Anyone know if that alternator will fit? or if the 4.0 and 3.0 alternators are the same stock which would mean it would work?
