| Post subject: | More airflow |
From what I understand, and I may be wrong, the diesel loves air. The reason we get black smoke under WOT is because it isn't pulling in enough air to burn the fuel completely and the remainder is exited as soot. Would it make sense to have a hood scoop to funnel in as much cold air as possible into the motor? Is there something in the software or MAF that would prove this to be untrue? A hood scoop with 3" exhaust and a straight through muffler... Possibly throw in a chip and we would be set. True? Dave |

Anyone have any thoughts on this? Thanks! |

I'll take a crack at it, although I am no expert. The main reason that you aren't likely to need something like this is that you have a turbocharged engine. The pressure differencial between air that is stagnant versus what is in a scoop is negligable compared to the pressure created by the turbo, so you aren't likely to see much of a difference. Your turbocharger, if operating properly, will pull the air that it needs from wherever unless there is a serious restriction such as a clogged air filter. |

The biggest thing a less restrictive air intake would do would be to reduce turbo lag. The turbo will ultimately produce the boost (unless there is a severe restriction), but the speed at which you feed the turbo air is directly related to the rate at which the turbo builds boost (and the engine builds power). Also, the colder (and denser) your air charge, the more power you'll get. |

We get the black smoke because we pushed down hard on the pedal and the engine hasn't enough air to burn all the diesel we just pumped in. The turbo spooling up is the only cure for that, or you have to moderate your foot. The truth in a diesel engine, since engine compression gives us the temperature to burn diesel, is that the atomized diesel has to literally find a hot oxygen molecule to mix it up with before it will burn. Turbos put in more air, so we can add more fuel, to get more power from a smaller package. We have to live with it. I guess I a little more moderate a driver than others, I haven't ever seen a big black cloud of smoke come from my CRD. |
