Polishing intake runners

Makes perfect sense to me and helps solidfy what seemed logical in concept. Explaining it in terms of energy spent follows right along with what I was thinking.

My thoughts were that if you suddenly give pressurized air MORE space it's going to create "turbulance" as it expands. Then when the chamber/runner constricts back down it requires more energy to press the air back into the smaller area. You're pressing the air against an angled surface and the suspended fuel is going to hit the side and come out of suspension.

That scenario seems equally damaging to the process as having a lip exposed.
