R914 not developing full power
in 912 / 914 Technical Questions
5 years ago
I was hoping you folks could help me with an engine problem.
New R914 on my gyro. 3 hours on it so far. Variable pitch prop, set at max fine pitch both on manual and on automatic. . Running E0 Mogas 91 octane. TCU works. Waste gate moves and does self test on power up . Turbo turbine spins. Idle throttle position corresponds with idle valve at carburetor. Max throttle position corresponds with max valve at carburetor.
Maximum static power we get is 4800 rpm and 27" MAP
Gyroplane manufacturer says we should see 5500 rpm. But I'm not sure I trust that statement.
We see no indication of turbo engagement, since the MAP is only 27". We should see around 39 at full power and much higher rpm.
Any ideas?
