Well, Lynn,
I guess I was the victim of disinformation when Andy told me
at Reno that
the cowl inlets were much larger than stock…
Here is a picture of the “small” inlets on Race
33 - http://www.sportclass.com/2003_gallery_images/2003_7_lrg.jpg
Here is a picture of the “large” inlets on the
factory Legacy - http://www.lancairlegacy.com/Gallery_images/Legacy_profile.jpg
Here are some pictures of the hole in the intercooler “clearance”
blisters that Andy and Darryl “forgot” to close before the race - http://www.sportclass.com/2003_gallery_images/2003_4_lrg.jpg,

Now, it is possible that the inlet area, for just engine cooling,
on Race 33 is less than the inlet area on a stock Legacy. But, you have to
adjust the stock inlet area for the air lost to induction air, which would
result in a functionally smaller air inlet devoted to engine cooling. I mention
this for the sake of discussion, although I don’t believe this is the
case.
I appreciate the correction, however, on the use of ADI
fluid and the spray bars.
Fortunately for all of us, there is almost always more than
one way to accomplish any particular engineering goal. Each method has it
plusses and minuses resulting in one solution out of a series of various
compromises. I am not condemning the use of plenums any more than I am saying
that George has the “only” solution to engine cooling. However,
from the data I have seen so far, and to the extent of my engineering knowledge
(which is rather limited, as I am not an engineer), I believe that most plenums
represent a suboptimal solution to the many compromises inherent in cooling
these beasts. On the other hand, I still think they look way cool and I remain
very intrigued about their design and implementation.
Lynn, is this
your cowling? http://www.lancair-builders.com/photopost/showphoto.php?photo=32&password=&sort=1&cat=504&page=1
I like what I can see so far. Do you have any more pictures
of the installation further along?
I hope all these links worked.
Best Regards,
Mike
