I probably could Andrew, so my apologies, your response made it appeared you have already made up you mind that I was talking nonsense. Perhaps I am, but I usually try to only state facts and opinions when I have some experience which I believe may be helpful to a problem. You had already received some excellent advice around gearing and how to tune engines, but appeared fixated on the fact that you Ruby was out performing Duncan's special. That to me dictates that something is significantly wrong with Duncan's set up, which I felt quite was likely to be carburation and timing This was because as you now know the gearing difference between your cars is insignificant, and now that you understand weight and frontal area better you will I hope realise that even with the same bog std engine specification Duncan's car should quite happily out perform your Ruby. Sorry if I caused offence by being offended.
