I don't have a 3G alternator, but rather the stocker. I do have the March billet underdrive pulleys. At idle, with head lights on, and fan motor blowing at full blast, my voltage meter drops and the head lights dim. However, as soon as I get moving (i.e. over 1,000 rpms) the problem goes away.
As long as you're not idling for an extended period you should be alright. Hope this helps. E
