alright so looking at some old school hot rod stuff where people tried out all different weird things i got a strange idea. anyone ever see a roots supercharger driven off of a turbine wheel? i took the thoughts backwards like 6-71 blowers being belt driven, centrifugal (somewhat of a turbocharger compressor) belt driven, so that makes a turbocharger a turbine powered centrifugal but ive never seen a turbine powered roots.

Im in no way thinking ive come up with some magic setup and i highly doubt it would work good but i envisioned this king of weird looking setup of a 6-71 on top of a motor with a turbine housing at each end. obv would have to be geared down a lot prob somewhere around 15-20:1 if anyone has ever seen anything remotely like this id like to see some pictures. i dont want to hear stupid comments and things like its impossible because anything is possible (not saying im going to make one)

I think the biggest problem you will have is the parasitic loss on the engine caused by the energy needed to turn the rotors...think about the size and weight of a turbo compressor wheel, even a big one like an 88mm versus a "small" blower rotor set like the tvs1900. Sounds like a worst of both worlds type of setup; tremendous lag and huge parasitic loss.

Yeah,gonna be too much lag in turn defeating purpose of positive displacement blower.

Those rotors are waaaay heavy.

Roots Blowers are positive displacement, meaning each turn displaces a set amount of air..... im thinking it will not work correctly with a turbine wheel because the turbine is not capable of either variable geometry or spinning at a seperate speed than the blower impeler.
