From my experience and from performance figures others have posted a 160 hp 9A with a Hartzell prop will burn about 6 to 6.5 g/h LOP at 150 kts (173 mph) at around 8,000 ft.
I noted this number and took it as a bit of a challege
This morning I took my EVO rocket, (280 to 300HP?) up to 8000'PA to see what I could do at 150knots TAS.
It took a while to slow down
but with the autopilot on level flight I was at
2000rpm, 14.5"MP burning 6.1 gph
It takes a certain amount of energy to push and aircraft through the air at 150 knots. Most RVs and rockets share a very similar profile, thus these results were not unexpected and I am sure that the RV14 will be about the same.
