Well a little while ago I posted a thread about my stock truck not passing emissions. After a whole lot of up grades and fixing a few things I finally got her to pass. My first shot my opacity reading was 44 out of 40 now after a rebuilt turbo, a bhaf and a new fuel heater I ran a reading of 2. I could not believe it my self and the guys at the emissions place made me run a second test to make sure, and sure enough. Not bad for a truck with 155,000, and not detuning the pump.

Just thought I would share

 

I bet I could get 100 out of 40.

 

well if that smoke in you pic is any inclanation of now much smoke you blow i would think 200 out of 40 LOL

 

For those of you not familiar with diesel emission testing, here's what we're talking about:



Arizona apparently allows 40% opacity, so he only failed by a little bit. 2% is hardly visible.

Newer setups use an impartial electronic probe in the tailpipe rather than a state employee's eyeball.

 

Those electronic ones can be fooled too. I've gotten by one year on my 93, due to equipment calibration malfunction. I like those tests, its only $9 vs $28 if the stuff works.

Its a joke here, its just to make money, and it all depends on which station you go to, as they all look for different things.

I've blown a 0 before, talk about throwing them for a loop, they just stand around and scratch their heads.

 

I blew a 2% the other day on mine. Kind of amazed me to say the least!

 

Gives a whole new meaning to DUI....could be DUI of smoke!!!

 

what is the test proceedure?

 

i was thinking the same thing. under what operating conditions do they test? WOT, idle???

 

It's a pedal stomp in neutral.

 

then i would fail, and my diafram is at the lowest point with the star wheel up and the smoke screw out and it still smokes.

 

heres a vid i shot this morning when i was done tuning.....for now anyway

 

Looks like 70% to me.

Sounds like the idle is a little fast, too.

 

hadn't got to the idle yet that was right after the vid

 

heres mine in a neutral stomp
