Well I couldn't sleep without trying to figure this out. Looks like it was the new smooth idler pulley next to the supercharger. Something is not right with it. I could see the belt tracking back and forth from side to side on it and everytime it hit the edge it would make the noise and probally causing the supercharger pulley to rub as well. So I pulled the entire wrap kit off and put the stock belt back on.
As far as I can tell no more noise. Took it for a test spin and was seeing about 18.75 PSI. So I guess brandons claims of .5-.75 boost increase were correct. This faulty idler is probally what caused the belt problems with the first pulley he sent me.
I ran it up to 100 mph. The air was 55 out tonight and my AF ratio was still 11.0-12.5. I really think I could push another 2psi with a smaller pulley and be alright. I'm gonna try to get with Brandon tomorrow and let him know what's going on.
