Hello all,
I have read a few posts saying that 160 kts at 10 GPM is not possible for an RV-10. I just want to report my experience on the RV-10 performance. My RV-10 is not particularly fast, in fact I think it is a couple kts short of Van's numbers, so I would expect other RV-10's to be better.
I have verified the true air speed with 4 ways GPS runs and find that it is within 1-2 kts. The fuel flow gauge usually reports about .7-.8 GPM high on fuel use compared to the pump at the end of a flight. So I believe the fuel flow is accurate and reads conservatively if anything.
Here is a picture of 162 KTS true airspeed at 10 GPM. The flight conditions are 8000 foot density altitude, just under 60% power, lean of peak EGT and 2100 RPM.

The RV-10 really is an efficient machine.
