| Subject: | Fuel flow markings |
Guys
I am now making the final configurations of my EFIS, and one of them is the Fuel
Flow.
For those of you who also have an RV-10 with Lycoming IO-540 engine and C/S prop,
will you please share your fuel flow markings,
Red (lower) range 0 - x gal/h
Yellow (lower) range x - y gal/h
Green range y - z gal/h
Yellow (upper) range z - w gal/h
Red (upper) range w - t gal/h
Thanks in advance
Carlos

Red Lower 0-3.5
Green 3.5-28.5
Yellow 28.5-30
Red 30
That should get you started. I have an Airflow Performance FM 300. Idle can dip
below 4 and Takeoff Power can hit 28.5.

Hmm, that is awful high fuel flow for takeoff. I rarely see over 24.5 with
Bendix RSA fuel injection., with stock compression and magnetos.
Pretty good rule of thumb is 9-9.5 gph per 100 hp. 27 gph at takeoff is a
number usually associated with close to 300 hp.
At idle I will be under 3 gph..

Sorry, I have a Barrett Precision BPE540-X that has 9-1 pistons and cold air
induction. Barrett rated it at 290 hp. A stock engine would have lower fuel
flow.
