undrdrive pulleys were the first mod i installed on my car.... they were also the first to be uninstalled to b/c at idle my car wasnt producing any voltage from the alternator. it slows down your accessories which is not really a good thing. try to find some light weight/same size pulleys instead

Hey Thats not a bad looking cobra how much $$?

i guess i shouldnt use it for now..my charge is weird. sometimes it drops down to 0 and back up and ****. headlights will already go to a little dim when im stopped. i need a new alt.

Youre supposed to be able to use the underdrives since you already have the 3G 130 amp alternator stock. You need to load test your charging system and figure out the problem and see if it really is the alternator.

RE: under drive pulleys

i put the summit aluminum ones on my '95 and there is absolutely no difference in charge at idle. these come stock with the better alternator though, and i dont have any big power-sucking electronics.
