There is a small like grinding noice in the morning when i turn on the truck, right by the whipple pulley. Do the pulleys ont the whipple supercharters wear out like the ones on the cobra. I know on the cobra i had to replace by billet flow ones because the bearing were going out. I would like to switch it out if that is the problem. The noice usually lasts a minute or two then it goes away. Any of u know heard of something similar???

I had the same noise a few weeks ago. It ended up being one of the idler pulleys on the bridge. Pulley ended up locking up and burning my belt off. To be sure whick one it is you can put a long screw driver or extension next to the pulley and put your ear on the other end. Acts like a doctors stethoscope. Find where the noise is loudest and you found your bad pulley.
Let it sit for a day and then take the belt off and spin the snout and idler pulleys. after it sits, it should make that noise or have some resistance thats not normal.
