Making the Compressor Wheel for the Mini SUPERCHARGED Wankel

What you see on this video is the compressor wheel of the supercharger. It is similar if not the same in function to the procharger or vortech superchargers.

Basically the cold side of a turbo that is driven via a belt instead of the exhaust gases like in a turbo. The difficult part which I can't make at all, or if attemted it wouldn't be presice, is the compressor housing.

This one will be printed in a metal 3d printer and the inlet will be finished off on my pocket NC to meet the clearances that I want.
