It's alive- well sort of. First start and there is a whistling noise that isn't the supercharger itself although it does make the appropriate noises. It has a pretty good sized vacuum leak from a 3d printed fl**ge that wasn't very flat and that is absolutely shrieking like a jet engine. Also it would not take throttle very well, probably because of the vacuum leak. But hey, i expected things to need tweaking, fixing and tuning. After finding the leak i lapped that part flat on a piece of granite starting with 80 grit then on to 120, and 400. I will put this back on tomorrow see if things are better. I am not concerned about the runners being sealed as they have an o ring in compression.. Also need to wire up the EGT probes and display
