you will notice a little bit, though pass on teh alt pully if ya got a big stereo or a lot of elex stuff. up to you, IMO leave the alt pully off.

I've never really been properly told about the alt pully.. but isnt it smaller then stock to make the alt spin faster and make up for the rotation of the smaller crank pully? Which actually would help charge?

that is the way it should be done, install a smaller pully on the alt so it stays working up to spec, and leave the rest as they (assuming you get an underdriven crank pulley, not a set of slightly larger pulleys for everything else which just would be stupid and costly)

tru, if the rest of the setup is properly matched, meaning *all* the pullys. more often than not, at idle you get charging probs and at cruising speed everything is fine.

most of R/T owners just swap the crank pully and leave it at that.
