 As some of those who attended will be able to tell you, it's tough to explain
concisely.  This group was there for five and a half hours of detailed
instruction, 65 slides and live demos via video and had the ability to ask
questions and pick our brains during the breaks.  That's a lot to put into an
e-mail!  I'm not trying to be evasive.  (If that were the point, we wouldn't
have done a free Saturday program and I wouldn't have flown from Baton Rouge
at my own expense to help. <g>)  I just don't know how to answer it in simple
terms, other than to say that you have to get the air to go where it's needed
and restrict the air where it's not needed.  It's needed most on the UNDER
cylinder fins.  The best advice I have is to look at a Cirrus.  They got it
98% right.  They missed two points that do make a difference, but they have
the best factory baffling I've seen.  If you baffled a Lancair to look like a
Cirrus under the hood, you'd be a long, long way toward the right answers.
