Hi David and Ira,
I guess you are both right, but achieved cooling-improvement on different ways.
David, I well remember our chat on the Europa AGM last year but have to admit,
that I thought of something cheaper than a new Propeller. I even would consider
this, when it would be "only" the money provided it's a reliable solution. But
since my Europa is on the Dutch Register, I'd expect considerable paperwork
with the authorities going along with additional costs. However additional
performance
is also tempting :-)
Ira, yes - Bud Yerly has huge knowledge of the Europa cooling modifications and
I know his comprehensive article. Since I can't do much myself and cannot bring
my Europa to his shop, I have to stick to more or less easy solutions like
removing the Thermostate first.
I have already modified the airflow in the tunnel with an aluminum sheet to
force
more air through the Radiator and the result is quite good when airborn in
all kind of OATs even in extensive climbs at MTOM. On the other hand I know of
conventional installations (XS-cowling and 914) like the one of Tim Weert from
Holland, who seems to have no cooling issues. The cooling-problem in my Europa
is either not dramatic, since I can run the engine for >10 minutes from start
up until take off in 28C (and that is with a coolant Thermostate which pushes
the temperatures quick to 85C). It's rather the situations like sitting behind
a queue at the holding position - like David described it - when it becomes
uncomfortable with one eye always on the CHT-gauge. At the AERO fare in
Friedrichshafen
I positioned my Europa 3 meters behind a Cirrus SR 22 to Keep the
CHT at 115C.
I'll remove the Thermostate first....
Anyway thanks for your advice!
Regards
Roland
