    Below are some video's with sound of the two noises i am hearing. First video is of a whine noise i have at around 1800rpm no matter what gear im in and seems to get allot better as the vehicle warms up "power steering maybe?". Second video is of what i suspect to be a supercharger coupler going bad, but wanted your advice before spending the money to buy one.

    In the second video it sounds like your coupler in the first it kinda sounds like the belt is to tight or something but that's not possible on serp belts so i'm not sure there.
