REFLECTOR: Exhaust systems

Has anyone looked into an air augmentation system?  I recall a Long Eze at
OSH last year that had this and I think he exited his exhaust very close to
the hub.  He had lots of other stuff too.  Auto Engine , very long prop
fiber wrapped extension requiring a support frame.  Also the T-34's has
this as a HP increase mod.  Could we use a big NACA  to add mixing air
around the exit of the exhaust?

Some are talking about longer prop extensions solving the problem but if
one
is using a different exhaust scheme this doesn't help define what we really
need to know.......  is there any consensus on how far the prop needs to be
from the pipe to avoid burning? Thanks.
