Supercharged dyno runs are a ton of fun.
I see one very critical thing with that installation that needs to be corrected right away. The head unit needs to be rotated about 90* clockwise so the internal oil pressure and scavange pump will work correctly or the supercharger will fail.
The snail can be reclocked to line up the piping to realign the discharge port once the head unit is properly repositioned. There is a flat bottom on the supercharger and that must be installed within 15* of being level or you should expect a supercharger failure.
Another thing is that a bypass valve should be fitted to control or eliminate that compressor surging problem to prevent damage to the throttle valve and impeller.
If you want any other help or want any info on the Rotrex please contact me.

I can not really tell from that picture.
Anyway, look at this picture:
You can see the supercharger. The yellow plugs are where the traction oil fittings are connected. You can see the flat bottom to the right. That flat bottom must be downward and within 15* of level.
The supercharger in the picture is turned like the way yours is mounted which is wrong. The flat side needs to be down with the oil fittings on the top.
In this picture is a Rotrex C-30 properly mounted with the flat side down and the traction oil fittings on the top.
