splat, has anyone brought up that the way he is porting it might not be optimal? It seems that im is polished throughout all the way into the runners leading to the chamber.
From what little i know, on other cars getting ported, we would leave the runner, just that final tube going into the chamber, rough, so that the air tumbles a bit before entering the chamber, that smooth runner lacks the turbulence caused by the rougher spot before entering the chamber. the tumbled air generally gives a better mix of a/f and thus a more efficient charge.
has this come up at all, or does this sound applicable at all. I am not an engineer, and this was just something I saw discussed, it seems plausible, but the difference also seems minute. and again Im only referencing the runners if that s what they're called, the legs of the spider if it was one.
