The bigger (new) Alt. pulley is so you would not loose voltage after going to a smaller main pulley.
Ahhhh you dudes are upside down. SMALLER ALT pulley = MORE ALT OUTPUT/
more alt sucking power. The smaller pulley spins the alt faster.
And on my F Bod the alt was not producing enough with the smaller crank (under pulley) and sitting at the light the car was surging and lights where dimming and
A/C on ,made it worse. I gave up on the whole deal.
