I'm not saying that I don't trust him. I'd like a little more education. Why does helmholtz vibration not take place? Or why is resonating such vibrations not important or possible with a boosted application?

I can see it differing based on cam intake close angle. Of course, this is what affects helmholtz resonance in a non boost application. Do you remember why? Can you pick his brain a little more about this?

I seem to remember one of worlds worst cars (from some list) not getting the helmholtz resonance right in the intake manifold. it was on car talk or something.

If i remember right, it made the gas in the carb bowl foam... not good

Thought this would be a good laugh
