I have seen videos and photos online of people using dyes and smoke to show where the air is flowing inside the port when on the flow bench.
Easiest thing to do is feed a cotton thread in the port when its running. Question is does this show anything useful. In mine it is only happy when its hugging the port floor and short side turn. If the thread is lifted up to the port roof it just goes nuts with what I presume is turbulence.
I was expecting the air to flow across the back of the valve and into the chamber on the centre side of the chamber since this would be the most direct route (straightest-no bends) but there is no way you can get the thread to come off the short side turn no matter how you try and feed the thread in.
Any one got any useful flow bench experience/techniques they want to share?
