I have a little over an
hour of flight time on my airplane
now and thought I would give the group a report. After first flight I
decided
to change the exhaust system. I copied Bill Eslick and Tracy's system.
I
am running Bill's SpinTech muffler. It is much quieter in the cockpit
now
and ground reports indicate that my exhaust is slightly deeper that
Bill's
but very close.
I have a long taxi to get
to the runway. Temps at takeoff
have been 150-180 for oil and 190-210 temp for water. Reaching pattern
altitude
I am at 210 -215 oil and around 225 for water temp. After leveling off
oil
stabilized to 205 and 210 water. Lots of room for improvement, but it
has
been 90 plus degrees for every flight. On the last flight I noticed the
upper
cowl is bulging between fasteners. I am waiting for Bill's upper louver
experiment to decide weather to try to exit the air high or low.
I am getting about 5000
RPM static and at 140 MPH the engine
turns up to 6200 RPM. I would like to do a couple ground runs with a
smaller
pitch prop to determine if I am over-propped or just not producing
power. If
any one has a smaller pitch prop for sale or loan please let me know. I
am
currently running a Performance Props Inc. 74x88. Takeoff rolls take
about 1000 ft. and climb out is very flat.
