I'm with you on this Jerry,
George ( down under)
I don't understand why you think the velocity is guaranteed to be higher in
the PP runner? That all depends on the size of the runners, and
ports. You can't just make a blanket statement like that.
Not
being an engineer I am used to my own stupid mistakes. The reasoning behind
the statement come mainly from two considerations: first the p ports breath a
lot better than any side port configuration thus more air is flowing through
them; secondly, there are only two runners instead of four so naturally the
speed will have to be double assuming the same size runners. If in the case of
side port, the intake runner i.d.s are reduced, the skin friction will be
greatly increased. Face it, side ports are a drag. There is no way velocities
in a four runner intake can ever approach those of a two runner p port. IMHO,
Jerry
