I have a 130 amp alt. the same fan as dbeck and runnig about 700 watts of stereo and only have a little charging issues at night with headlights,fogs,fan.stereo,brakes,and blinkers on.The Volts drop low enough to kick one of my amps off.But other than that it charges great.

do you 2 have the underdrive alternator pulley on or the stock? i have the crank and waterpump one's on but not the alternator. can i run the underdrive alternator pulley with the electric fan, msd, and amp without draining the battery?

i run underdrives with the setup i have told you about.. charge is decent at idle and like 14 at cruise, my alt is a monster though.
