Reply to "Intake "Popping" - Help!"

The intake runners don't connect to each other, so how can they steal air from each other?



The intake runners not being connected to each other may be exactly the problem.

Reversion at a certain speed with your cam may be inevitable.

In manifolds with a common plenum reversion from one cylinder is drawn in by another cylinder and so nothing is noticeable at the top of the carb or injection throttle blades.
