I would like to hear from unorthodox racing pulley owners. Have you had any issues with your UR pulley? How long have you had it installed? And (very important in Louisiana) did it make a noticable difference in the effectiveness of the air conditioning?? I have had my UR pulley for awhile and have been trying to decide if I want to install it. I would appreciate hearing comments from anyone with a UR pulley on the box or xA.

I've installed it last month. No issues so far. I can't really gauge the difference since I added a header at the same time as well. =-/
