If you've been poking and/or hanging around here for a while, you may have seen Ron talk about (or have seen a video of him working with) a gent by the name of Mike Holler.
I stumbled across a link to a series of articles he's written, which I'm here to happily share with everyone:

Notice how his "Powre Lynes" supposedly create turbulence inside the intake manifold just like our Groove?
I think ours would create more, bigger turbulence sooner through the throttle plate's range of travel.
I also think we can apply this to the exhaust system to make the hot exhaust gas pass through more efficiently without increasing the diameter of the tubes, for another incremental gain in power. We're not mixing air and fuel at that stage, but would less precious metal be needed in catalytic converters?
