This is another reason, why I don't like excessive smoke and believe that we can produce awesome power without resorting to plumes of afterburning soot.
As fun as it may seem to some, unfortunately, it just attracts the attention of the lawmakers who'll tout it as a justification.
It reminds me of when I used to smoke (cigarettes) and insisted on my rights - then I gave up and realized that whilst I chose to smoke, others around me couldn't easily choose not to inhale my secondhand smoke in most situations.
I have no objection to a brief smudge as the turbo catches up, but a black fog cloud will only lead to yet another nail in the coffin of our current diesel driving (relative) freedom.
Just think how much more power could be extracted if all of that partially burnt fuel you see in the smokeout pictures, was instead burnt cleanly in the engine and mostly turned into crankshaft and turbo energy.
I say, save the black fog for the drag strip and racing venue, but keep it clean on the road - you never know which lobbyist/senator/law maker may be following...
