Im installing stacks on my 1990 F-250 in a couple of weeks, and therefore I was wondering how I could get rich black smoke to come out of my exhaust stacks

any body that knows how to do this?
At this time there is noe visible smoke at all from my engine..


Thanx

 

Black smoke is a sign of a POORLY tuned truck. You could try to find a tuner that'd change the pump to run richer, thus pouring more diesel into the engine.

 

Yes, to get smoke you have to burn excess diesel. The pump is easily turned up to do that.
Scroll down to the pre-powerstroke diesel page. There have been plenty of posts there on turning up the injector pump and on fitting stacks.
You can post your question there or do a search for the information. Good luck.

 

this does not sound like a very smart thing to do.

it is a ticketable offense in some states.

it is bad for the air.

it is just not right.

 

huse - that post was a joke, wasn't it? Please say it was a joke.

 

Just block off part or most of the air intake, starve it for air some, it will belch black smoke like no tomorrow.

Why anyone would want to pump out black smoke is beyond me though.......

 

Hook a tree chipper behind it, throw some stuff in the bed and try to merge onto an interstate. Should smoke nicely.

 

Turn the fuel pump up one flat maybe a flat and a half, but you better have a pyrometer on it cuz you can overheat your egts quicker that you would ever believe.

Also, you might have to invest in some code G injectors from the 93-94 7.3 turbo.

 

I dont want black smoke all the time just when i use full throttle.. Iwant black smoke out of my smokers because i kinda looks weird with smokers/stacks without any smoke...

so what would happen if i turn the IP 1/4 would that help?

thanx

 

it would mess it up.

 

I never heard of ANYONE doing this.

You should atleast do some performance mods to the truck.

 

i see where all these people are coming from, but its not always bad..look at "performance" trucks at the strip or at a truck pull who boil out enough smoke to choke a flock of geese in the air..im not real sure how to accomplish this task, ill ask my friend when he gets up he has a 93 that pours it out at full throttle im pretty sure all he did was bigger injector, code g maybe? and he had our local diesel performance shop tune his fuel pump

 

Those performance trucks are designed with all out performance in mind with no care for the environment. When the daily drivers get done at the track they are re-tuned so that they do not blow smoke on the street.

That said, not all performance trucks blow smoke. The current world speed record holder Gale Banks did not blow any smoke when making his record speed run.

 

Black smoke is just unburned hyrdocarbons from excessive fuel. The tuner drag trucks dump all that black smoke most likely because the higher EGT's helps build even more boost which makes more power. This would have no effect on a normally aspirated diesel, just a waste of fuel. More fuel without the more air to burn the fuel is pointless.

 

I'm thinking you'd better move this thread to the diesel section, or join a forum that deals only with diesel power.

I own a 470hp 12.7 l diesel. It's setup to pull. That's what I do. I can pull 108,000 lbs up an 8% grade and mine ain't belchin' black smoke (I get a puff on shifts). Black smoke may look cool, but as I said earlier, it's a sign of a poorly tuned engine.
