Old, vanes & vortexes

[Frank Evan Perdicaro]

I've been out for a few days.

There are various vortex induction systems out there in the 
commercial world.  For EFI and carb., there is the Tornado 
induction managment system, patented by a local guy (here in 
SoCal).  Also, one of the aftermarket EFI "plate" adapters
has sprouted vortex-generator cuts.

Vortex generation can provide lots of oddball benefits, from
better fuel scavaging from the walls, to slight compression, 
to more effective squish.  All need tuning.

There is an SAE paper out there, republished in a book I skimmed,
about a spiral/helictical intake tract with the valve at the center.

To put a few threads in the blender, can we make a Hilsch Vortex 
Tube in our cylinder heads?

Just yesterday I finished "Race Car Aerodynamics, Designing for
Speed".  Lots of good references, various discussions of vortexes
on the _outside_ of motors.  Air probably cannot tell the difference...
