Hi all,
I did a static run up of my 914 today. I had it tied off to the tow hitch on my
car with the tail weighted down with an 80 pound bag of salt. Apart from white
knuckles and a bit of vibration it was a non event.
My 914 is not developing full power. With the prop set manually to fine pitch
the engine would only develop 5100 rpm and 34 inches of manifold pressure. I
would have expected 5500~5800 RPM. I have checked the throttle and it is moving
to full open. The tach is an EIS engine monitor and I have no reason to suspect
it is incorrect
I need a few data points. Could some one tell me what is the maximum RPM I
could
expect with an Airmaster set manually to fine pitch.
Secondly, I cannot get the engine into boost. My first thought is that the
waste
gate might not be set correctly. I removed the cable from the servo and it
might not be in the correct position. Can anyone tell me how to set it
correctly.
Conversely, .... 34" is 100% power, could the TCU be limiting it? if so
what parameters can do this. I only one I know is the air box temperature.
Thanks, Paul
