Koen,
I wish that I understood your analysis and the chart I inserted. Why are you using 4000 RPM in the calculation? Doesn’t CO reach its maximum power around 2500 RPM when the piston speed starts to exceed the CO flame speed? You can probably tell from my question that I don’t understand. Would three holes give greater airspeed and higher quality gas?
Bottom line: If I were to try Kristijan’s nozzle set up on my 1800CC MGB, what in your opinion would be a good size to start? Would 4, 10mm holes like his give me greater airspeed and better gas? If I used a slot instead of holes, what opening area would be optimum?
