Default humming noise after UD pulley install??

immediatly after i installed ud pulleys, i heard this humming noise coming from under the rear of the car. I've had no cooling or charging issues and im not running the alt pulley. I've never heard of this issue with pulley's before. What could it be?

i might put the stock wp pulley on and see if it goes away. I thought the problems w/ pulleys was with cooling and charging issues. I'll probably takes off these pos **** pulleys, there worthless. Definately not worth the time, money, and problems they cause, to gain a whoppin 3hp.

Thats what it sounds like, the fuel pump. My only guess would be b/c the alternator has been slowed down, not giving the pump enough power. Also, my belt does seem a little tighter than the previous one I had, but i doubt thats it.

Ricenator, i like how you're keepin it real with the two tone and pin stripes. Im trying to decide if i should repaint in the two tone or just spray it all metallic grey.
