Alternator Shootout at Idle (136 vs 160 vs 250 amp)

I take 3 alternators, head to head at idle to show which one will perform better than the other at idle, and will also a 49mm alternator pulley on all 3 to see how much that helps to increase the voltage. I have been experiencing a lower than desirable voltage at idle ever since I installed the electric cooling fan for the radiator and the ATI super Damper with a 25% underdrive pulley.
