I have just completed the test phase of my RV7. Throughout the testing, I expected higher speeds than what I was getting. I am currently attaining 110-120 knots with 2200 RPM /22 MAP. The aircraft is configured with all but leg fairings and wheel pants. I'd expect the lack of fairings and pants would contribute to a loss of 10-20 knots. That doesn't make up for the 170-180 knots that I am hearing from other RV7 owners.
I have an EFii ignition/injection system with CHTs/EGTs in the 185/1300 range. The ignition timing, however, is rather generic in settings and I am suspecting that it may be contributing to the lack of power. The EFii documentation to tune the timing is rather weak. Anyone have insights or suggestions to 1) identify the lack of speed (fairings, wheel pants) and/or 2) how to insure the timing is set correctly?
