If I buy under drive pulleys and a 120 amp alternator. will that help the loss of amps going to my battery? or would that be ruining the point of putting the pulleys on? or will I still be getting the loss of amps at a idle?

I have had UD pullies on for a couple of years now, and have never experienced and adverse effects. Yes, it doesn't completely charge at idle in gear, but I get a full charge in park or neutral. So basicly, how often are you going to be at idle in gear? I do have a bit of stop and go traffic, still never had a battery go dead. Personally, I wouldn't worry about the charging, but if you want to go with a bigger alt. then go for, it will help if you are running something else that draws a bunch of power, ie a serious stereo system.
Hope this helps out

Yep, I totally agree. Also, Scott, what "bolt-ons" do you have? Nice ETs!
