914 / 912 fuel flow - Comperesation data
in General Tech Discussion
12 years ago
Hi guys,
I have just done a fuel burn flight test today. The numbers impresses me. My plane is a Sonex tail dragger with my personal custom built 912UL-F3 Turbo, Efi, Intercooler. It would be interesting to compare data with other 914 engines as well as 912`s. I dont think 120+ KTS and 13-14L/h is bad at all. Neither 150kts and 19-22L/h.
WOT 5000rpm and 42" MP - 27L/h Approx 155-160KTS IAS 2000-3000ft
High cruise setting 4773rpm, 35" MP - 22.5L/h Approx 150-155KTS IAS 2000-3000ft
2700ft, 121KTS IAS, 5068rpm 15.7L/h
2700ft, 122KTS IAS, 4577rpm 14.1L/h - Super ECO
