I and every thing else that I have read agree with your comment on the centrifugal blowers...
Yeah they sure were not shy about blowing their own horn...PR dude was working overtime..ha ha....
I did enjoy the history and development of the SC as used in the automotive industry.... ...amazing what they could do in the late 1800's...I would kill to see how one of those rotors are made...
This link has some pics of an edelbrock e-force supercharger case being cast...I have a feeling their are NO pictures of the rotors being made..hush hush secret squirrel information dontcha know
