Please help the ignorant.
O-320 E2D fixed pitch
The manifold pressure gauge reads 30 engine off.
In flight at 2350 rpm 3500' it reads 26.
Go higher to 10500 it is stilll reading 26 @2350.
In either case push the throttle in and it goes to near 30 and RPMs climb to, or near 2700
At 2500rpm any altitude it reads near 30" but I can still advance the throttle and increase RPM.
Can I really be getting 29-30" of MP at 10500 feet?
At first I thought that I was over pitched on the prop but now I question the validity of the MP readings. This, because it would not be able to get 2700 RPM if it was already at atmospheric at a lower RPM.
Am I understanding the issue correctly or do I need more education. I am ready for more education or a different MP gauge.
Thanks, Tim.
