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 ________________________________ Message 2 _____________________________________ Time: 05:20:06 PM PST US From: Robert Jones Subject: Re: RV10-List: Fuel flow markings 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.

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..

Barrett rated it at 290 hp. A stock engine would have lower fuel flow. Robert Jones > On Feb 8, 2020, at 17:55, Kelly McMullen wrote: > > =EF=BB > Hmm, that is awful high fuel flow for takeoff.
