I'll do it eventually. I'm designing more for Under the curve driveability than I am for a few HP at RPM's I rarely spend time at.

Hard to say. It looks like they squeeze the pipes at the MAf mount area, but to what internal diameter I don't know. Necking down the pipe and then expanding it again does improve velocity (like a venturi) and could provide some leaning and more power depending on the ID. The placement of the MAF inside the tube will have an effect also as air flow through a tube is faster in the center than it is toward the outside. I'd tend to doubt that 20hp number though..
