200HP (just kidding)
Bryan, I'm with you and agree but...
At level cruise and leaned I seem to flow (like you) around 4.5-5gph. BTW - the Revmaster is rated 85HP@3200RPM. But likewise my IO-360 burns 10.5 ROP in cruise (or 7.5 LOP) but on takeoff it needs about 16gph. The extra fuel goes to things like cylinder cooling and detonation resistance.
In yesterday's flight, WOT on takeoff/climb I had trouble getting to full throttle without the engine faultering (expirence has shown this to be too lean a condition) and CHT's were a bit hot. This was flowing (according to the chart) around 7.3 gph. I'll duplicate the flight later today with a richer needle setting to verify.
It would be nice to hear from others who have a fuel transducer (red cube) as to what your max fuel flow shows up at in a steady state Vy climb at WOT/full-rich.
