So these runners extend inside the plenum. For optimum airflow they should have a nice radius at the entrance, and a velocity stack or "trumpet" is even better. Due to space constraints I had to to keep the velocity stack relatively small, but there are diminishing returns beyond this anyway. Pics below are some Solidworks renderings of what I came up with and what it looks like on the tube intake runner (courtesy of AtomicLabMonkey of course).

Next up is to put the runners on the flanges and position them on top of the engine. Coming in a week or so.
