If I put on a set of underdrive pulleys including the one on my alternater,wiil i still have enough amps to power my system?

 

IMO stock fbody alternators suck. I kill about 1 a year with a sytem with 1 big amp and 2 little tiny ones. I upgraded to the 140amp iceberg and all is well so far, It still dims the lights and what not when its really rockin but havent killed it yet, and i do run an underdrive pully on it. If your alternator is stock i wouldnt risk it but if you have upgraded give it a try and see how it works for ya....if you lose too much juice put the old one back on. Actually just follow my credo "Beat it till it breaks, then buy one better!"
