Hi! Paul/ Duncan.
Thanks for the message below. Even without any gills but with the Jabiru
arrangement I had no such thing as cable tie meltdown. The nearest sign
I had was some "spirowrap" which ran under the exhaust manifolds. As I
said I believe the presence of the gills in flight allows the upper cowl
pressure to reduce so discouraging the downward cooling flow. If the
gills were added to allow residual cooling after shutdown it would be
simpler to open the top access panels immediately on shut down. I have
ordered "the fibre glass engine cooling hood" on my engine which should
also assist in preventing the heat build up in the cowl top and I expect
my intercooler air to assist with cowl top cooling too. I would have
expected the Jabiru being fully air cooled to have far more residual
heat to dissipate on shutdown anyway and since I didn't have a problem
then I will leave the gills on my new cowls closed, unless I get some
more feedback against.
I've not had a rattling response on the question
Regards
Bob Harrison G-PTAG

Hi All,
Actually I have my gills rear ward facing. It wasn't by design, I just
made a mistake and I didn't even know until Andy pointed it out to me.
Although I don't have before and after measurements, the underneath of
my cowl seems cooler that some other people have reported. I base this
on the fact that I don't have any cable ties that melt under the cowl,
whereas I have heard many reports from others.
One of these days I must smear a bit of oil around to see what is
happening
Paul

IConversion of the gills to a rear-facing exit may prove beneficial (to
reducing cooling drag), although care needed to ensure fuselage
composite not overheated. I have the moulds for such a mod., but never
tried it out.
