@shall_spotting the Twin screw mounted superchargers like my TRX has sit on top and you are correct . The procharger is a centrifugal style power adder. Its more efficient and acts like a belt driven turbo . Centrifugal use ball bearings and oiled via wet sump design lubrication . While roots style have teflon lined twin rotors that need rebuilding often and use sealed bearings lubricated with grease typically.
