So when running 200F LoP and 15 gph, I am cruising 235-240kt TAS on 59% power? I get more efficient with each iteration!" I figured Walter would have jumped in here by now. All the previously listed numbers could be correct. It all is based on the brake specific fuel consumption (BSFC)of your specific engine. Some engines are better than others. Carbureted engines usually have higher BSFC numbers (poorer fuel economy). You need to get data for your engine and then the "factor" works LOP. Note.... LOP not rich of peak. The BSFC at take off power is much much higher than LOP cruise. Craig Berland
