John,

What engine are you using? Your web sight says that you race at 2,500 =20=

RPM. I have a Lycoming O-320-D1F and run at 2,700 RPM.

The first race that I ran in, I used 2,500 RPM and came in last. You =20
need to use full throttle, highest RPM and lean while watching the =20
CHTs. If you don't want to run your engine at maximum power, don't =20
bother to race.
