Roland,
Send me pictures of your cowl and install when you can.
Normally when folks have problems they have missed something obvious to me
but not to them and I fail to mention it. Again, I fly with a stock set of
parts by the book, in a hotter environment and overcool normally with the
914 with no intercooler. We are missing something that works for me and my
clients but not for you. We do not want that to happen.
Check your exhaust for leaks. If #3 is leaking a small amount the CHT is
off the charts on the ground and is blown away inflight unless it is a
narrow jet that impacts a 912 carb float bowl which makes things really
exciting.
Best Regards,
Bud Yerly
US Europa Dealer.

Subject: Europa-List: Fwd: Re: Cooling issues XS 914 on the ground
A little "progress" report:
I closed and sealed the gap between the upper edge of the air inlet and the
top of the cooling tunnel and made two 2-hours flights (one low at 2500 ft
and the other one high at FL 110). It was - of no avail. Actually I achieved
the opposite, namely CHTs of 100C in the cruise instead of 95C
(decreasing veeery reluctant in the descent) and also higher oil
temperatures, reaching almost 130C in the climb at MTOM 90 KIAS.
I was at the Fly in at Wyk/Fhr EDXY and met two other Europa owners, of
which one had a Trigear. I thoroughly inspected his cowling and cooling
tunnel, which was a whole lot different to mine. He had a separate opening
in the lower cowling under the radiator for the oil cooler and three
additional openings with gills (similar style as the ones on the sides of
the upper cowling) on top of the cowling just in front of the windscreen. If
we meet again I'll make a ground run with his upper cowling that is easily
exchangeable.
Every Europa is different indeed - and I'll go on experimenting - maybe I
should make the inspection doors on the upper cowling controllable from
inside the cockpit for ground operations (a lot of hot air exits them after
shut down, when I open them) - I guess I would be the first with that one
:-)
