I apologize up front if this thread is not appropriate for this section but I think it will fall under technical. Please move if needed. Below I have a few pictures of my 2013 GT500 stock supercharger pulleys system. I think been having boost issues since I bought this car and I am 100% sure previous owners didn't perform proper maintenance on it or paid good attention to light issues. The car has some good days of boost with 3rd gear pulls showing 14-15lbs of boost, but as soon as it warms up good it starts drooping very low, in the 7-9lbs and feels slugged. Today I tested the car as soon as I got out in the street to catch it cool enough and the outside temperature was fair in the 78-81F and the car did the same thing. highest boost I saw was 10lbs. Additionally, I felt some light jerk while I was testing on 3rd and 4th gear pulls. The pulls I did where from 3K rpm to 5K rpm. in 4th gear at around 3K rpm it moved slow and I felt a few light jerks, like if my clutch or rear end differential was slipping. I did not found significant rubber dust in the engine bay, but I clean the crap out of the car a while ago and didn't even thought about checking for that. I just check the belt and pulleys and the pictures below is what I found. Can you guys with better experience with superchargers let me know what you think?
