I remember reading an earlier post concerning the volume of air anticipated at the intake by the PCM. The gist of the post was if the air volume was increased by a higher flow intake modification, the PCM would respond by venting the excess before it entered the turbo.
If that is the case, the K&N results pretty much blow away that bit of programming theory supposedly incorporated into the PCM by DCX.
Hopefully, I will live long enough to know the rest of the story. So far, the episodes have been good, but have yet to qualify for a non-fiction banner.
Likewise for the exhaust flow. If the System is progressively expanded to a larger diameter (from the 2 1/4" O2 sensor plate to a 3" exhaust system), then the result would be a more rapid cooling of exhaust gas before it exits the tailpipe. This nets higher exhaust gas density and slower extraction.
I guess it is possible that slower extraction of a higher volume exhaust gas may equate to higher performance.
Something about this picture just doesn't add up....
I am not trying to start a war, or question anyone's integrity. I believe that each of us has an experience to share that is backed by their own research. However, none of those individual research projects are collaborating what we have heard from DCX, and even fewer are in-sync with what we have been taught about air flow, gaseous dynamics or the general concept of physics.
I know the general consensus is that a bigger intake and exhaust equals supersonic transport, but has anyone sorted out the claims against the results that physics allows?
If we were able to completely bypass the PCM, some of these claims may carry some truths. But, with the PCM trying to neutralize anything that it sees as out of it's anticipated parameters, it is like trying to fill a five gallon bucket made of window screen with a four gallon source (that may or may not have a leak to begin with).
