i think some other people here with chips and reflashes here need to chime in and correct me if im wrong.


why do you want smoke so bad? that is just money right down the drain. and with fuel prices the way they are, that isnt very smart. jmho.Edited by: steiner43511

There is a really big misconception on this 6.5 forum as to what 'black smoke' really is -


If you're blowing black smoke, you're wasting fuel, big time - black smoke is unburned fuel, from not enough oxygen to sustain combustion.


Ideally, as you accelerate, you will only see faint smoke at nite in the lights of a vehicle behind you - this indicates the engine is getting the right ratio of oxygen and fuel to make power.


These 6.5 systems are primitive, so if the fuel is cranked up, it is cranked up across the band - from idle to top end.


What you will see, for a really hot chip - and this is what I got - you will get a puff of smoke while the turbo is spooling up Boost, and then only a very light haze, disappearing as Boost comes up over 10psi.


Any more smoke than that will jack the EGT's up to an unusable level for steady load, such as towing, hauling, etc.


The old 18-wheelers, pre-turbo era, had to crank the pumps up to get the power, and black smoke was considered good - altho it was not.


Black smoke is unburned fuel, which is a light oil, and which carries heat just like cooking oil does.


You cannot fry chicken in water - takes oil to get the heat up.


Oil can get to 1500-1800deg and up without burning if not enough oxygen is available - 1500deg will ruin pistons and such under sustained conditions, such as towing.


While this may not be the answer you are looking for, it will be the one you will remember if you are in pursuit of 'blowin' black smoke' to impress the girls, and such.


Black smoke is not good for your engine's survival.


Word up......

The cool thing is having no smoke at all :)

We've a lot of very small Diesel engines in passenger cars here pretending to be high-tech and environmentally friendly and having particle filters and any such bells and whistles. But when they try to accelerate, they smoke badly.

My truck doesn't smoke, she just accelrates. That's pretty cool :)

If you want smoke, unplug the vacuum line to the Wastegate Servo cannister, then make a run past the bowling alley, and watch all the little kids stand around and marvelhttp://www.dieselplace.com/forum/smileys/hihi.gif

not sure if u was jokin or not but would that be somthin that would cause a big loss of power wouldnt it?

Precisely - because blowing black smoke is missed opportunity......to make power.


If you're seeing Dodges and Fords blowing smoke, it's probably because they need some tlc attention - bad fuel, air filters, fuel filters, fuel additives, IP service, etc.


Black smoke simply means the fire went out before all the fuel was burned.

In addition to sage advise JD has given, remember also the 6.5 pre-burns fuel in the pre-combustion chamber, so you aren't dumping fuel directly on top of the piston, lessening smoking ability.


Smoking until the turbo provides enough air & engine "catches up" with the fuel is not a good thing. In the Navy we had a saying "32 Knots & No Smoke" that was a phrase of compliment, saying your plant was giving all she could as efficiently as possible, we would laugh a Dieselmen or Boilermen that could not make their ships go fast without smoking. (Of course it was easy for us being jet powered, a smoking jet is cause for real concern)


Now in WW I & II when needing to hide and make smoke helped pre-radar days, ships would make smoke on purpose to hide from the enemy throw in an extra burner with special smoke tip orifice drilled out to add gobs of fuel for making smoke, maybe thats what Ford & Dodges are doing, hiding from fact they are driving a Ford or Dodge http://www.dieselplace.com/forum/smileys/smiley36.gif.Edited by: Turbine Doc

Ja, the smoke is just a concealment for a lack of power! :)
