What in you opinion is the best way to couple a turbo compressor wheel to an 8mm motor shaft ? Do you know what setup phantom is using ?
I think some sort of direct coupling is best. From looking at the phantom website I think that Rob is custom machining the motor shafts, or may be having them made to order at this point. It looks like the end of the shaft is drilled and tapped (using a mill and custom clamp). My guess is that he is either creating a shoulder on the shaft for the wheel to rest on, or widening the bottom portions of the hole in the wheel.



This all gets very tricky to machine and requires a lot of custom setup. I'm sure I could do it, but I'm I'm glad I found the SeaDoo supercharger which has turned out to be surprisingly well suited for this.

As it happens I bought a T70 turbo as part of my testing plans. If your seriously thinking about using one let me know, I'd sel it to you for dirt cheap.
