laser, i truly admire your engineering capabilities, u can literally make your own parts.
no offense tho, but engineerically speaking, if u spin those 2gear type blowers right now at even 90k rpm, it wouldnt even generate and push the same amount of air down the carb versus the carb just pulling air like usual.
i think the blade gears are too small, they will on constrict the flow.

dont let me stop u tho, continue, id like to see this. if i had the capabilities, i would experiment on this as well. maybe start wid a a bigger 4 stroke engine,

why dont u design a trumpet, or turbine style tube and blade, and fabricate a supercharger out of that. the roots style i think is a more dificult process to do.

can i see your machinery someday? im in the bay area.
