I have a 03 cobra with steeda 2.81 pulley with the idler. I've noticed that when I punch the gas in 3rd gear from like a 60 the rpms kind of hand around 4k and it sounds like the belt is slipping as the blower sound does not increase, almost feels like wheel spin then it pulls normally past there. Only seems to do it in third. Any ideas? Could this be belt slip? I will try and get a video up. Thnx.
