Alternator Pulley?

[FrvrDreamin]

Im stopn at Laurel Mountain to get some UDP's on Thurs and was wondering if i should leave the Alternator Pulley OFF because of my system?
On modded mustangs some said it was ok to leave on and others said they had to leave theirs off...

Any opinions?

[INSANELY CRAZY]

everyone has there own opinion on this one... i have run all 3 and had no issues, i've also ran just the crank u/d pully and also had no issues...

if you have an upgraded system (stereo) i would leave the alt alone....unless its an OD pulley.

I'm only pushin I believe 800watts, but have my flipscreen too...

So i guess the alternator pully stays off then?

You'll be fine to run the underdrive pulley. I used to have two fosgate power series amps with over a 1000 watts rms with no problems. You have to remember that with the radio tuned down it's not going to draw hudge amounts of power. The only time you may notice something is when your sitting at a light at night time with your lights on with your radio cranking. Your lights may dim some. Worse come to worse you can always swap back to the stock pulley.
