There is some disagreements in circles about jet engines looking at the weight of fuel consumption per hour vs weight of fuel the plane can carry. And that the fuel usage is way lower thus the A/F ratio is vastly different than an ICE engine.
The other one is, why are Oxygen enriched fuels like Q16 being used in N/A racing engine if O2 has no power. Don’t flame a fire…. LoL seems that more O2 makes for a better fuel burn reaction…
