Jared,

There is a direct correlation between engine health and hp and that is how much work can it do, not necessarily how many RPMs. The static engine run up test is to see how well match your engine and propeller pitch are. If you engine is older and had a cruise prop, you may not make enough rpms to safely get it in the air.

So for you plane we need to know the pitch of the Sensenich (it will be between 60 and 65 inches) and consulting the annual checklist in the maintenance manual we see on page 2 of 16. that the following pitches and rpms setting are given (interpolation between as need in a linear fashion) – remember high school?

61 2100 – 2275
63 2050 – 2225
65 2000 – 2175

So there you go to get started.

Roscoe,
Im a new Tiger owner – just to follow up on the above, the static rom is the max rpm I’ll see when I fully open the throttle on the deck. Ive got a 63 pitch prop, I’m at a field elevation of 2400′ and I’m seeing 2200 rpm at the start of my takeoff roll. Sound like the proper application of a static rpm eval?

Eric,

Tiger static rpm is 2150 – 2275, you did it correctly on the ground with full throttle, so your are in the range and the Sensenich prop is a better airfoil than the McCauley.

Cheers

Roscoe

Thanks Roscoe!
