Bumping old thread - I have a BF 2.76 upper, new metco idlers & BF snub idler, using a Gates K080745HD. I've put around 150 miles on the car since installing the parts listed, and the belt is completely black. Car hasn't been re-tuned since smaller pulley, so I've stayed out of boost completely, slowly putting around town on weekends. Is this belt slip? How do keep the belt green?
