pullies

I had the AEM alternator pulley only (underdrive) and noticed a slight difference.

Then I went to the Unorthodox Racing light/underdriven pulley and noticed more of a difference and stayed there.

With the UOR pulley, I lost the harmonic dampener (opinions all around about this), but have yet to experience any problems. Also, after driving 10k miles with it, I noticed that my headlights are slightly dimmer at idle (with stock radio and fog lights on). Never noticed that when I first put it on, and believe me, I checked. And no, I did not run both pullies at once.

Good luck.
