I wonder how those fins are going to hold on with hot tack-welds at 100k rpm? Maybe he'll do the same on the turbine side, just as an experiment... We can only hope
All that trouble, when everyone knows all you really need for an instant supercharger is a 12V DC to 120 AC converter that plugs into your car's cigarette lighter, a hair dryer, & some duct tape.
And speaking of trouble- if that guy's really doing this, I suspect there's gonna be plenty of it when one of those tack-welds gives way.
OK, gotta go now & & plug in my free-after-rebate, Miss Priss hairdryer & outrun the local gendarmes!
