Re: intake port molds

Just what size/shape is best? A wise old sage once said, "Truth is where you find it!" My point is, there is soooo much more to evaluating porting than a "static" flow bench can evaluate. I'm talking about harmonics set up by the opening and closing of the valves; the interruption and reflection of air flow - harmonics in other words - which play an important roll in "internal supercharging". My point is, what looks best on a (static) flow bench is not necessarily what is going to be best in practice. And, for most of us mortal people, the math gets sooo complicated that all we can do is get close, and then experiment and see what trends develop. The proof is in the pudding, in other words, along with what is desired from then end product. Gotta run. "Mo later!" P.
