I use to run an RR UD crank pulley and did not like it. My AC did not blow cold or well at idle and the car ran hotter in the summer.
Hmm? Never experienced any of that with the UR one & I live in TX - summer 9 months & fall 3 months.
 
RR here only issue is I need to go out and tighten up my belts now and I cant stand working on my car in the cold but I really cant stand to hear my car squealing in the morning.So today when I get home I will tighten them up hopefully gettin rid of the belt issue.
 
I went to the RR site and the price is higher then what was stated in this thread. Can i get a discount somehow?
 
Has anyone tried the OBX underdrive pulley. Found one that is about $80 cheaper than the Unorthodox UDP.
 
Well I bought the OBX UDP from ebay for my car. Got it for about $100 shipped. That is $85 cheaper than the Unorthodox version and that does not even include shipping. So I got a heck of a deal. I have not heard anyone installing this version so I will give you guys updates on the install and how she does. Here is a pic of it:

Does anyone know if I need to get different belt sizes for and OBX underdrive pulley?? I haven't even seen or heard of anyone using this brand UDP
 
Is it a must to torque the UDP bolt to 120lbs of torque? Don't have a torque wrench right now and I really want to install mine now. Anyone know about how many turns 120lbs of torque is??
