Trick flow

The port size has zero to do with how much air an engine can move. Look how much extra the intake manifold adds to port size. It's about flow, not port size. Port size is just used for marketing purposes. Period. It's not the size anyway, it's the shape.

Totally missed the mark on this one RRR. Volume is huge when designing the engine and top end specifically. All engines have personalities, and the port volume has a lot to do with it. Power curves, peaks, shift recovery, pretty much everything is affected by the head’s port volume to one degree or another. It’s only marketing if you don’t understand what it represents.
