New engine is flying
Posted: Sun Feb 19, 2012 4:38 pm
Finally got my new O-360 engine flying in the Rebel today. Definitely way
more power, no question about that. Am trying to break in the new cylinders
and having trouble getting up to 22 MAP or 65% power without going too fast.
My windows start opening up a bit at the front at 125 mph. My prop might be
too fine, as I have to run about 2500 rpm to get 22 MAP.
Take off and climb is good though. Was seeing 1800 fpm on initial climb.
Basically, it now performs the same on the ampibs as it used to on wheels
with the O-320.
Really puts through the fuel though, with full power, at 18.5 gph. The O-320
only did 13 WOT.
Handling and c of g exactly same as before. Did not have to change my
elevator trim. Did notice having to use more right rudder on take-off and
climb though.
Cooling is good, too, so very happy about that. Rear cylinders ran about 350
or less, Had to tape off the top of the oil cooler to get the oil temps up
to 185 which is the highest I saw today. OAT at the lake today was 19 C.
Got a few adjustments to make and some finishing on the cowl, but at least
it is flying again. So I am a happy camper today.
