Ok fellas I need some help. My car is making a tapping noise. I can tell you what it is not Its not the motor or the supercharger. Each pulley was checked first with a stethoscope and pin pointed one of the idler pulleys. It was checked when the belt was off no issues. Now to the idler pulleys they were checked and switch and still when put back on same tapping sound. Now what I can tell you is that when the idler tension was moved while the belt was on the noise stopped. Here is the video I made of the car making that noise. https://www.youtube.com/watch?v=-3g0K6slxcI
