How does under-drive pulleys effect the AC output on those hot summer days?
I understand they give no more then 1 or 2 hp. If they also make the AC noticeably less effective then I have yet another reason to give them a pass.

Nice looking blue Unorthodox pulleys would be nice under the hood but I don't really care that much about how the engine compartment looks anyhow.

 

No noticable difference in my AC at all. I have the SR ones.

 

Probably would notice the A/C not working well in very hot climates, but I don't think that includes Canada.
