The electrical load demanded at the alternator is what I mentioned. Going to a smaller pulley will not reduce the demanded load.
Um, a smaller pulley would spin the alternator MORE!
This is a larger pulley.
A larger pulley also has the benefit of exerting more torque for the same effort, so that would provide some benefit. Not much, but some.
I'm not sure what the alternator has in the way of bearings on the shaft, but spinning less would seem to save those as well.
All in all, it's not a big gain by any stretch of the imagination. I would mainly consider it a longevity mod.
Personally, I only went for the P/S UDP.
