Gale Banks put it pretty well lately when he said "Running smoke free is the only way in to NHRA meets. There are a lot of bandits out there who think smoke is macho, I'm not one of them. Smoke is the result of incomplete combustion. I prefer to burn the fuel in the engine. Smoke is power you can't read on the dyno or feel in the seat of your pants, period. And the EPA is watching the street smoke boys. Thanks to that, as a board member of SEMA I with others will be dealing with EPA at the upcoming SEMA show trying to protect the very guys who build and sell such products. Products who's smoke production will blot out the Sun. Smoke is defended in some of the posts with a "stick it where the sun don't shine if you don't like it" attitude. As to those guys, I guess that would be where ever they happen to be. "



All the injector makers, chip makers, turbo makers are hard pressed to increase your tq/hp without churning out more soot into your DPF. How many of you 6. 7L owners have already had DPF problems or heard of lots of folks with DPF problems?



Why are "THEY" not giving us more test mules with 25k on the dash with their product?



I have offered to be a test mule but have not any takers yet!!

I agree 100%.



I think the new future is 99. 5% smoke free.



The NHRA has ALWAYS complained about our smoke. Occasionally they have tolerated it, they even tolerated our 30"+ crank centerlines...



The smoke we see might be awesome for sled pullers and such, but I think that the new high tech will be smoke free power. That's power you can use!



Ever tried to tow with a 500HP Cummins? If I try to tow hard it throws so much smoke it stops traffi. If I could have a 450rwhp truck without smoke I would be all smiles all day!





This may go against all the "smokers" but I think it is the right thing to do.

sounds like someone is buying banks marketing hype ...



banks has to run nitrous at the track to keep it smoke free ...



THere are lots of people running NOS at the track but I've never seen another truck make that much power without a puff of smoke. Banks has done a great job with that truck. Now if they could only make a tuner for our trucks like that... ... :D
 
Hype or no hype, the idea of this thread was the idea that with a troubled 2007-2008 trucks with DPFs and some are buying into the idea that it might be safe to install add-ons of all types to help your performance without hurting our DPFs. I am not against adding injectors or chips, I would just like to see more data.

I think I will just keep my good ol' 98 12 valve, and keep things on the smoky side. . No DPF's to worry about, no computers with buggy software, no computer re-flashes. . Can't you remove the DPF and leave it off, or is there sensors on there?? Not too sure or familiar with these new motors. Gale Banks can have all his crap and burn it clean, but when it comes to customer service he comes in last. . I had numerous problems with some of their products that have now become a paperweight with wires coming out. . Kind of looks like a metal jellyfish. . That's my $. 02 on Gale Banks.

This is all great and good but the reality is if you stuff a CAT and a DPF in the tail pipe you get clean air and use 30% more fuel. Where does this help the environment. When Banks comes up with a way to make it smoke free and still get a minimum of 20 mpg then let me know and I will be first in line. My 99 dynos 450 RW HP and tows like theres nothing behind it, all with a minimum of smoke and still getting 19. 9 mpg. You want to get on a soap box, go to a few third world countries and get them to clean up thier filthy exhaust, belching out of all the gassers that won't come close to meeting our EPA standards and when they catch up to us then start preaching to me about smoke. And what about EGR???? Where is the sense in cooling the air charge through the intercooler to make it more dense with oxygen, and then dump hot exhaust gas back into the air charge right into the intake. This causes a reduction in O2 and less efficient burn. Go ask Gail Banks to come up with a better idea and see if he can answer that question. Some how I doubt you will get a chance to ask it let alone get an answer.

Rant over!!!
 
Ms. Diesel Lady,



Once again let's get back to my original point and the thread topic. WITH ALL THE PROBLEMS WE ARE HAVING WITH THE DPFs I would like to see all the manufacturers show us some solid data as to what their products are going to do to our DPFs in the long run. Is that a soap box rant?



Pre 2007. 5s it don't matter. Pour a gallon of water in the intake, it will not ruin the exhaust but it will make your valves do kinda funny.

you have a good point. But Gale Banks is the last company i think will do any good for our truck's. they stand behind marketing and not research. there race truck is a good point. One you dont know what is under the hood and you will never see what they use on a shelf for sale.



i am more worried about a stock truck with the dpf at a 100k miles. since the lack of flow, extra back pressure, and raw fuel pumped trhough the turbo what effects will that have? we dont have the traditional turbo any more. in a 100k miles are we going to have to perform double bypass to clear the exhaust from the valves to the DPF. I'm just saying!!!!!!!
 
I don't think this is about Gale Banks, vs. Edge, vs. Bully Dog, etc. It's about making power without ruining the DPF's and truth in advertising.



When I had my own shop I was always put up against the wall when customers would ask me about warrenty issues. Will this void my warrenty? I had to say yes. Although the ad says no? Ruined my credibility from the start.



Now, there is nothing being mentioned, or tests showing, the effects the aftermarket will have to the DPF's.



We are going through a steep learning curve between keeping the DPF clean, and melting it down, or colling to much, and clogging it up.



I think we will have to see more programs that work WITH the sensors than trying to trick and bypass them.



How much more fuel the truck uses, how much backpressure is added from the factory or how more "innefficient" the motor is from the factory is negligent to this conversation. It's about how the DPF and engine is effected with added power. There are much higher consequences when adding power to a motor that has a DPF compared to the old school non-emission motors... .

Okay, sorry I get pretty passionate about this subject. We are both on a soap box and I meant MY Rant not yours. I am just tired of these Enviro wackos preaching about smoke and how we all need to make our trucks smokeless but the conveniently forget about how this kills fuel mileage. I am all for someone figuring out how to make the diesels clean, but without fuel economy to go along with it they are just being hipocrites. I don't believe that EPA is as concerned with the planet as much as they are concerned with having job. Just like politicians, what happens when we have enough laws and clean air? They are out of work.
P. S. Most of the newer chips that are produced now only add timing for at least the first two levels, which gives you much better performance and no more fuel, thus added fuel economy. So there are lots of manufacturers that are making products that don't make smoke. And these products will not hurt the DPF. It is the soot that gets them clogged. Also, I have the new 6. 7, totally stock and the tail pipe is black with soot. So not only do I get crumby economy because of the DPf etc. I have to say they don't work that well.
Just my opinion.
 
In my line of work, talking with some of the engineering reps from the OTR engine companies, they said that if the EPA would allow them to tune the engine for optimum combustion efficiency and treat for NOX in the exhaust, fuel economy would go up and soot production would be essentially zero - no need for a DPF.
 
Just a reality check.

If it blows black smoke like an old coal burner that is cool?

In my book it is rude. You worry about fuel mileage, yet you belch out black smoke like a frieght train? (unburnt fuel out the tail pipe, Fuel mileage , Huh?)

My 07. 5 with all of the emmission crap on pulls like no tomorrow and still has a clean tail pipe after 5K miles. I don't know how to tell if it goes into regen, maybe cause I don't try to make it smoke? Maybe?

Just my bit
 
Smoky Thinking

Yes, it is easy to get "passionate" on this subject. So here I am with a counter-soapbox. But lets try to keep generating a little light with all the heat.



One way to start would be to refrain from intro-and-re-intro-ducing name-calling into the threads in this forum.



DL, not everyone with a slightly-or-greatly differing viewpoint from your own is an "Enviro wacko" (or a hypocrite).



My own little defensive contribution to name-calling is the acronym "DGAS-ers", which expands to "Don't Give A ****-ers". ;)



Since I'm sure you welcome constructive critique, I'll offer a couple of thoughts about terms:



"The environment", as usually thought of by those interested in improving/protecting it, does not include "fuel economy",... although you seem to think that is an essential ingredient.



Without considering all the associated complexities;

Whether vehicles get 1 mpg or 100mpg has no effect on the environment, if those vehicles are smokeless, and if by smokeless you mean harmful-emissions-free (and if we ignore vehicle production enviro-costs).



Fuel economy is a measure of convenience to humans, ... not of environmental health. The fact that oil has been underground, undisturbed, for thousands of years has had no ill effects on the environment. And if we run out tomorrow, and your mpg goes to zero, the facts that there would then be no oil underground (or on top) and you would be greatly inconvienced, would also have no ill effects on the environment.



It is what we humans are doing with the oil that is effecting the environment negatively (among a thousand other for-our-convenience activities), and apparently there is at present no "convenient" way to continue to increase the use-rate, while lessening the harm-rate, if by "convenient" we mean cost-free.



One of the costs, at present levels of technology, seems to be somewhat less power efficiency in those engines which most-effectively reduce the harm-rate.



Now an easy "Us vs. Them" way to look at the "Enviro Wackos" vs. the DGAS-ers (to again use the ever-so-tempting name-calling technique) would be this:



EW's say - "We have been destroying the environment, ... and by 'We', we mean ALL-OF-US, and by 'The Environment', we mean OUR environment(and our children's, children's children's, etc. ). By "environment" we don't mean mpg, ... we mean clean air, pure water, abundant wildlife, flora, etc. , ... i. e. , a healty Earth.



We are willing to acknowledge that correcting this situation will require something of us, in convenience and in dollars. We are willing to pay our share of the cost. We will support new technologies (solar-electric, fuel-cell, wind/wave/tide-generation,) which offer relatively harm-free power. Meanwhile, if some of that payment must be made in fuel dollars, so be it!



Now to the DGAS-ers:



Many of them seem to say - "OTHERS claim the environment needs protection. IF that is really true, let THEM find a free-for-ME way to fix it. I certainly don't intend to give up any of MY "conveniences", to support THEIR cause. Why should I pay for something THEY want?



Oh, . . but I do believe in clean air, water, etc. "



Now a little thought should make clear which of these positions is the "hypocritical" one.



Another convience, for the conscience, is the attribution of ill-motive to the "do-gooder" OTHERS. As in - "EPA (EW's/anyone-who-disagrees-with-me) doesn't really care about the environment,... thay only care about their jobs!"



Right!



They'll be "out of work" when we have enough clean air?



Not a problem. At the rate the rats in this particular cage are reproducing, "enough clean air" (or enough anything) is unlikey to mean job-loss for anyone.



In any case;



Farmers will be out of work when we have enough food.

Drs. will be out of work when we have no illness.

Policemen will be out of work when there is no crime.

Firemen, ... when we have no fires/other emergencies.

Soldiers, ... when we have no wars.

Teachers, ... when we all know everything.

Etc. , etc. , etc.



All of these situations are desirable.



None of them are probable.



What is your point?



We can have discussions, even intense ones, and express differing opinions, as friends.



But it is difficult to feel friendly when someone is calling you names, ... either directly, or by simplistic association ("lumping").



I see the merit in being both a hunter-fisher and a conservationist.



I am a diesel owner-driver.



I am also an environmentalist.



I am amazed that any thinking person could not-be (or would be reluctant to so-state).
 
heres an even bigger test, find someone smart enough to take all of the RETARDED junk off my 41 thousand dollar truck and let it run like it ought to!!!! that would be impressive
