A couple of notes from the race that might interest the non-racers as well.
Jon Ross beat me by 0.16 mph in a near identical RV8. He used 2 gallons less of fuel, which makes me think he is better at leaning the engine at sea level than I am. Hence my thread/question under "Traditional Engines". We both have parallel valve IO-360s.
Dick Martin was 10 mph faster than I, but he burned 41 gals. So, he just used more power. If we use the cube law, my airplane and his are roughly equally efficient. (We both have RV8s, but Dick has the IO-390 angle valve engine).
Dave Anders and I used the same amount of fuel (35 gals.)in the race. He went 34 mph faster (no, I didn't drop any decimal points) than I did. Dave has a very slick RV4. He also has a lot of horsepower, but couldn't use it all, since he only has 42 gals of gas on board.
If Dave and I flew the same speed on a cross country, he would use much less gas than I.
So here is the point of racing...once a year we have fun and try to beat each other, but the rest of the year we enjoy the fuel savings.
