No but not sure what exactly it sounds like. I keep thinking I have to be pushing the limits of the 6rib on my truck but all I hear is the supercharger screaming. Not sure I would hear the belt or not.
What can I log to detect belt slip? Sudden jumps in rpm?? Manifold pressure dropping while rpm increases I would guess?

In the video you can hear it, or at least what I believe it to be belt slip at the 11 second mark. It's right before the shift, there's a change in engine tone and S/C whine. I had a video a while back of a buddy (LastCall) who had his truck on a dyno and you can hear the belt slip clearly as he hit the top of his rev range.
It could be something else completely but from what I'm used to hearing that's what I think it to be.
Not sure what all you can log, but you wouldn't notice a drop in pressure, more like a lack of the pressure climbing. It's a fixed linear raise in boost on a screw/rotor type blower that is proportional to RPM, and if it noticeable flat lines that it's can be an indication of belt slip. Also visually seeing belt dust on your shroud/pulley's is a good indicaiton.
I'm sure some of the blower guys have better ways to tell if it's slipping.

. the thing ur pointing out at the 11 second mark is actually the converter locking which people think is a slipping trans/belt, the only problem im facing is a squeak that i recorded in another video, i think the belt needs some tightening, shifts weren't dialed in so this video was for fun only lolnotice the squeak as soon as i hit the pedal in first

Yeah that's the sound of the rubber you left behind haha.
Impressive build , just read all 24 pages.
Question though, what fixes the gap between fuel rail and the lower manifold after the spacer is installed, im lookin at buying one ..
