I know UD pullies take a bit of the load off the engine. But how does this effect everything? Sorry to sound newb about this. I mean less strain = more power more MPG etc but what about things like your AC? any affect there?
I installed mine a while ago (2-3 years), I do not remember my AC not being as cold. It was a while ago so I am not 100% on this but like I said I don't remember any effect on the AC. I use AC a lot.
wow another pulley thread..........as far as cooling, charging is concerned it wont affect them but the A/C just a bit but once you are cruising you wont notice
