[Tigers] Hood Floating

[Steve Laifman]

Steve S.,

A standard louver allows air to move from a high pressure area to a low 
pressure area.  The NACA (NASA) duct is not designed to be an air 
outlet.  Instead, it is used in aircraft as a"submerged" inlet.  For 
cooling purposes, it allows air to be drawn in with a minimal air flow 
disturbance.

It is commonly used for aircraft and racing cars. They have been tried 
at speeds much more than twice 90 mph.

An excellent short article can be found at:

Illustrated, with lots of references.  Note aircraft and Ferrari 
applications.  None leave the "hood" open.
