Note that once you put on that non CARB approved Focus Sport cold air intake you are legally in the same area as I am as far as federal emmisions regulations. That stock air filter is very much part of the system. My plans are to meet emmisions but not the visual inspection.

as i understand velocity and torque are tied together LOOSELY.
velocity comes frome venturies, funnel shapes, goofy pointless curves and length.
pressure and flow are part B and part C.
this is really complicated fluid dynamics or whatever the science elite call it.
ALLSO NOTE the comment on the first page about the slow tip in.
if you suddenly DUMP lots of air in an engine - especially backing off the throttle and then slamming it down again - like in racing...
your mixture is gonna be all over the place.
bad for the engine, bad for emissions.
super fast plates might make you go rich/lean/rich/lean faster than things can adjust.
especially if you accomplich your velocity and flow goals.
nobody has addressed the basics here and ive only scratched the surface.
freeze! put your hands up and stop the rocket science!
i say engines 101 are in direct conflict.
