Hey p4ndiamond,
I have the same supercharger (V7 JT) on my 03 MM, been up & running with a smaller length (second) belt since august '22, but the car was in storage from oct until just now. I have slip as evidenced by some (not a lot) black rubber powder around the supercharger. I am just about to pull the trigger on an 8 rib conversion, however, it sounds like from your comment in the video that I might be able to get rid of slip with a smaller belt? Curious, could you say the part number and length of your belt? Many thanks
