Just throwing this out there for people to know about it. UR has made a pulley to replace the airpump. It's for those who have replaced or want to replace their airpump, but have some trepidations about the tension for the water pump and already using an underdrive main pulley. The only other is the greddy pulley kit that would be double underdriving the alt/water pump. Some use that set up (replaced main and greddy kit) with no problems other than dimming lights. This allows you to save 8 pounds (not 10ish like a straight airpump removal) and keep the same belt wrapping around the stock water pump pulley. I just think its great someone made one for the car and wanted you guys to know. It's 175.19 as an introductory price.
