With regards to 'air spinning intake devices' -- seems to me that any time you
get air spinning as it goes through a tube or enclosed space you are going to
increase
friction between the air mass and the walls of the space simply because of
centrifugal force.
This would perhaps be countered, or reigned in, somewhat by the vacuum in the
center much like a tornado but I can't see how this changes the basic fact
that more,
denser air is scrubbing against the walls of the tube or container. Either
way it just puts more load on the vacuum and thus the engine.
This would seem to lower V.E. or volumetric efficiency; more work to move same
amount of air.
But maybe some intakes are so oddly designed that spinning air has less
turbulence than non but that seems fundamentally broken to me, not sure why
other than
what I already wrote.
