You kids are going to end up spending $3000 on a blower that makes you an amazing 15whp more.

Also, Eaton has made very few "twin screw" compressor style blowers... anything they have done in the compressor style blower market has never been mass produced nor would it ever come close to fitting inside a m90 case.

The "twin screw" stuff you are thinking of here are basically just gen6 roots blowers.
