Intake Manifold Porting - Bad Idea??

[jlevie]

haha thats the part that no one argued about. Supposedly if the air will move faster with less turbulence if the inside is not like less than 50 grit roughness. And if the random protrusions are cleaned up the faster the air moves. The faster you get the air to travel before it hits the injectors the better. I really don't know though, school me. I open to all ideas.

Actually one of the tricks for increasing flow through the intake and head is careful roughening in selected parts of the passages. That causes a boundary layer to form and stick. Air on air is less "friction" than air on metal.

So the current plan then is no smoothing, just matching the ports the head.

Took the intake to a the shop and the guy there recommended I leave it since I don't have a lot to play with. He said I wouldn't notice much of a difference if it was ported, and that it is good the way it is since it is smaller than the head. So its going to just get a good pressure wash and I'll put it back on with the new gaskets.
