Hello together, maybe someone can help me further and this is about the compression ratio and its effect on the engine power. It is about a via compressor charged engine. The engine has an original, as a suction cup, a compression of 9.8:1 and was charged while maintaining the compression via compressor, which is not unusual with this engine. Later the compression by other pistons was lowered to 8.5:1 and the car was retuned. Unfortunately, no Power measurement made with the original compaction. Can you say about what is lost in readout if you only lower the compression when everything else remains 100% the same? I only have the power value of the input measurement before resetting. The background is that I could better estimate the quality of my conversion compared to others, with the same engine, since I always wonder that I have a relatively low power at relatively high charging pressure.
