Topgunz - air to air upgrade

Are there any good indicators of belt slip aside from rubber shavings around blower? I have minimal shavings, i don’t see any slip on datalogs through 7300rpm it makes or at least holds boost at 1.3bars but i’m still peaking at 4.5psi. I’m using soapy spray around supercharger and coupler for leaks, and then pressurized smoke test from front of intercooler.
That said, still managed to make a STI sell his car, and i was pretty happy with how well i hung with an R6 and very modded GTR all things considered and i’m not even on e85 tuning yet

Your only making 4.5psi? Have you taken it to the dyno? What is your whp?

According to the rep I talked to at Vortech, if you see any belt dust, you have belt slippage.

I haven’t, still etuning with Seb. Belt dust is likely from when I first put it on I wouldn’t be surprised if i cleaned it off i wouldnt see any more. Must be a leak somewhere. Confusing as before I had a new blower shaft put in i was peaking at 5.8psi and that was with belt/pulley walking and slipping it’s way to death.
I guess if i just put marks on the belt and pulley i would in theory know for sure if it was slipping
