Much as I would like to spend all of my time reading Jabiru information I
regret that you are misinformed - if someone is making comments on the
Jabiru group about cooling then it's either a namesake (!!!!!) or someone
using my name. I have never posted anything to the Jabiru group and don't
even subscribe.
Sorry I can't help there.

Subject: Effect of Propeller Blades on Engine Cooling
To All:
Of late, there has been an interesting dialog on the Jabiru builders
net (jabirubuilders@egroups.com) regarding the effect that propeller design
has on engine cooling. Tony Krzyzewski (Hello, Tony) seems to be one of the
more active participants in that dialog. In part, much of that discussion
has focused on the effect that the design of a given propeller, particularly
the airfoil/chord that falls within the propeller arc encompassing the
cowling air inlets, can have on engine temperatures. Of particular interest
to me was a recent discussion of the relative cooling benefits derived from
blades with larger chords (e.g. wood props such as the Prince) vs. props
with much narrower chords (e.g. Warp Drive, Ivo, Airmaster, etc.). While I
lack the engineering expertise to fully understand all aspects of those
discussions, I've found them to be of considerable interest and very
enlightening. Certainly, they are excellent "food for thought" (a Colonial
expression, yes, Graham?).
In any event, perhaps Tony would be amenable to summarizing the Jabiru
Builders group's discussions on this subject for the benefit of his many
friends here in the Europa community?
I would add, at risk of repeating what I believe I have already read
in some previous communication within our group, that anyone contemplating
the installation of a Jabiru engine might find that subscribing to the
Jabiru Builders net to be of some value/interest.
As I'm sure most of you know, Tony's arm can be appropriately
"twisted" at tonyk@kaon.co.nz. I'm sure he has absolutely nothing better to
do. Are you there, Tony?
