REFLECTOR: air oil separators

Wed Dec 8 09:49:55 CST 2010

I am also running  a PZL 350cil engine. The dynamo sheet which came with the
engine showed 205 HP at 24/2600. I just don't see
235 HP at 20/2350, unless you have the fuel injected version of the engine.
My experience over the past 12 years of flying with the
Franklin, is that due to the high overlap of the cam it does not like to run
below 2500 RPM in cruise. My normal cruise is 65% ~ 23/2550  ~ 175 KIAS.
