Question on port matching

Rat Bastid.
None of the you tube videos in this thread support your contention that the opening in the intake man where it meets the head should be bigger & that it helps power because a smaller opening kills power, posts 28,40, 89. You mention fluid dynamics.
Water is a fluid. To duplicate the above scenario, where the port in the head is smaller & overhangs, get a garden hose & aim it at the corner of your house. See if you get smooth flow...


Let me say it again. I know you have some mental issues that keep you from understanding simple English.

The first thing I said was don’t bother with the port match. If you don’t put the correct SHAPE back into the ports it’s a power loser.

I have never said to make the manifold bigger than the head. Get that through your thick skull. I said IF you have to have a mismatch at the head, make the manifold bigger than the head. I didn’t say that every intake manifold should be bigger than the head. This is why someone who has no idea of what they are doing shouldn’t be doing any port work. You can lose power very quickly with a bad port match.

Go back and watch the very first video I posted. It shows exactly what happens when you put a square edge down stream of flow. You get vortices. The other videos show what happens when you have a change in section. You get the same thing.

I know your limited experience and inability learn hamper you. This is another time when you need to go sit at the kiddy table and let the adults talk. You are clearly not capable of contributing anything of substance.
