- tighten the tension pulley bolt
- check the belt tension with gates phone app, it should be close
- if needed, unscrew the tension pulley bolt and adjust a bit the tension bolt, screw the tension pulley bolt and recheck again with gates app

This method really helped me dial in my belt today. Thanks @
vgi
My belt was way too loose before I think. I was getting belt powder on parts near the SC plate. I also thought the cogged pulleys were the reason why the whine went completely away, after switching from smooth pulleys. But seems like my belt was just too loose.
I also couldn't get consistent results on the gates app because the belt was so loose. I'd pluck the belt and wouldn't get any results, or it would jump from 15hz to 120hz or something like that.
After using @
vgi method above, I was able to actually get the gates app to read a consistent result. It is reading 55hz after every pluck (as well as I could actually feel it resonate now).
I'm going to drive around for a week or so and check back if the hz stays consistent (or my belt breaks from being so tight now). If it's still 55hz I might try and dial it into 60
Edit: well now that I measured the bolt, it's 19-20.5 mm depending on how you measure it exactly. So that puts me a little more at ease about being the correct tension now. Plus hearing the whine again is awesome!
