Intake manifold flow test. Interesting read!

interesting read, but I don't like constant flow. An engine is disrupted flow. On the intake side, it's a quick, big, gulp of air and stop! On the exhaust side, it's a quick, blast of shoved air in "pulse style" with a slamming door shut (valve). Intakes and heads truly need to be bolted on an engine for the ultimate in accuracy.
Never thought of it that way.
