I hate to be a pessimist or sound that way but how many flight hours do
you have with this engine?

Subject: [LML] I have a Zehrbach engine in my 4p



I have a 500 hp direct drive (no gear box) V-8 of 650 cubs installed in
my 4P.
I am attaching some pictures for those disbelievers.  The first one I
took at
a small airport in WV. near Morgantown.  The picture shows Darus
Zehrbach
setting at his PC programing the two engine computers as the engine is
at
a cruse setting of 350 hp.  This unique run stand can measure the torque
of
the engine.  The prop he used is a 105" three bladed Hartzell on loan
from a
King Air.  We were able to put 8 or nine hrs. on the engine before
loading it
in my pickup for the trip home to IL.

The next picture is in my hanger just after unloading.  Picture three is
with
the engine just after installing it in the 4P.  The last picture shows
the intercooler
and intake system.


I could not believe how smooth and quiet the engine ran.  This engine
has
duel electronic engine controls with duel spark plugs.  The electric
system has
duel independent systems ie. two batteries, two alternators along with
the
ability to interconnect the two systems in the event of an alt. failure.
one of the
alternators is the very large anti-ice unit while the other is 100 amp.
Darus
even found room for an air conditioning compressor.
