Underdrive pulley???
so I was nosing around on moesperformance and saw something called an underdrive pulley that is supposed to give some performance gains. I don't really understand what it does. Anyone?

Torque reduction on the accessories, AC, water pump, power steering pump, ect... Reduces the power needed to turn them thus freeing up some ponies. Kind of like getting a 4.56 gear/gears except on the other end...

yeah it slows down all the accessories. DO you really want to spin you alternator slower have your AC less effective and your water pump pumping less for a few ponies. 3 hundy too. ***** dat.
