Man..i was about to buy the pulley until i read this:

3.17 What does an underdrive pulley do?

By changing the diameter of pulleys running off your engine you can increase
or decrease the amount of revolutions the pulleys get (think about gear ratios
for a moment, and general gearing thoughts) Anyhow, using an underdrive pulley
you can make less revolutions, sapping less power. This is good to use on say
power steering or A/C. I do think that underdriving your accessories probably
sacrifices how well they perform. You'll probably get less steering assist
and cooling. I don't think it's wise to mess with your alternator.

I got it in some Honda FAQ from Customimport.com

Any comment?
