Re: Exhaust size and free power.

Okay,

I said I'd let you know when I found out about the exhaust device (cone
in
a megaphone).  It is based on what is called the Cowanda effect.
This is not a smooth transition, it is an abrubt change in the fluid
flow.
The original research was, I believe, in French and the name of the paper
was:

"Increasing fluid flow by diverting it from its axis of flow"

If anyone has time (I won't have any for awhile) and desire, you might
search for this on the net and in SAE resources.
