Airflow with the Restrictor

[BeaverGuy]

Have any of you measured the air flow of your engine and compared it to the theoretical max aiflow? I just did the calculation for ideal condidtions and compared it to the air flow for a 600cc and a couple smaller displacements. Needless to say, it seems the smaller motors would hardly be affected by the restrictor at all. I came up with about 75 g/s of air as the absolute maximum airflow through a 20mm restrictor. I'd be interested to see what teams have measured or calculated themselves.

I'de be interested in this also. I'm currently building a flowbench for this exact reason. It should be done within a month or so, but you'll probably have an answer by then.
