Below are two charts showing  a short flight on 2/18/18. The first one shows RPM, TAS, PALT and FF. The area highlighted shows 171 knots TAS at a pressure density of 8500 ( not shown on chart ) with a FF of 8.5 as I had leaned it back some. With the current prop pitch this is about top speed. I typically cruse at 160 knots with a FF of around 7.3. This flight was done with one person on board and a fuel load of 26 gallons ( 32 gal is max ), OAT was 57F on the ground.

The second chart shows EGT, CHT, oil temp and oil pressure. This engine runs very cool. The highest CHT I have seen is 340 degrees in the summer and I leave the oil cooler about 95% blocked off all the time. Engine will typically use one quart between oil changes.

The third item is an oil analysis report showing data back to 2014.
