DPF Deletes and Feds

[Bassboats]

Just read an interesting article on the ProPickup magazine website about DPF delete kits and how the EPA is taking action against the manufacturers and installers. According to the magazine's editor, it sounds like the feds are getting real serious about enforcing the smog laws. http://tinyurl.com/afsosrf

I read the post on ProPickupmag.com website about the EPA going after the companies that sell those "dpf delete" kits and tuners. It reminds me of when catalytic converters were being cut off back n the '70s. Sounds like the diesel guys running those kits and tunes will probably be in the market for used DPFs. I think a shop down the road has a couple laying out back. Wonder what I can pick them up for?

Merged topics, Don't need duplicate topics.

Its not a problem if you know where to go to get an inspection.

[kstruckcountry]

What inspection?

 

I doubt anyone with a delete will be trying to put their DPF back on.

Edge settled with EPA yesterday, settled to pay $500,000 fine.

Ill sell you mine lol. :-D

The pro tuning shops that specialize in adding horsepower to stock diesels figure that there is a 3% gain in power by doing a DPF delete. It is hardly worth the effort and money even ignoring that it is illegal and the engine is likely to generate 100x as much soot out the tailpipe that everyone around you get to breathe.

 

P.T. Barnum was right that there is a sucker born every minute and there are lots of companies happy to sell unneeded do-dads to people from chrome plated valve covers and aluminum housings to ignitiion wires in pretty colors. Emissions controls are a pain in the ass at times but so is paying taxes and so is paying the monopoly company an exhorbitant amount to pick up my trash at the curb in the containers when it would be easier to put the trash in the back of my pickup and drive down the road and let my trash blow out the back along with the extra pollutants from my tailpipe.

 

I grew up in the Los Angeles smog basin and can remember when driving down the freeway I could not see the buildings on the sides of the road the air pollution was so bad. It is still like that in Mexico City and in Beijing and other cities where there has not been an effort to minimize the pollution coming out of the tailpipes of vehicles. This air pollution kills people and in the USA alone there are more than $12 billion spent on hospital visits alone from people having asthma attacks as a result. So if the feds decide to start enforcing the laws in this area it makes a lot of sense.

 

It is not legal to have a fully automatic firearm or a silencer and so it is also not legal to sell parts for converting a firearm to one that is fully automatic or to sell a silencer. Somehow the people selling the DPF delete kits and tuners have stayed under the rader which is odd. In the 1970's the feds clamped down on people removing catalytic converters and installing a section of pipe so they could continue to use chearper leaded gas and so the muffler shops and everyone else stopped selling the sections of pipe to anyone for any purpose. Lots of otherwise intelligent people thought that the removal of the converters provided a dramatic boost in horsepower and gas mileage which was a complete fiction. Race cars without converters had a lot more done to them to get the horsepower they achieved and could use out on the track. In many cases reducing the back pressure in the stock engines reduced horsepower and led to burned valves.

 

I have a choice as to whether or not to have a diesel powered truck and it is a package deal with the engine, the DPF, and the associated maintenance that goes this setup. I have the option of getting a gas powered truck which will also have a catalytic converter and have its own emissions systems that will require some attention. My Duramax LML produced 765 ft lb of torque and deleting the DPF to get and extra 25 ft lbs makes no sense at all.

 

If you need to customize your diesel truck then invest in chrome and a lift kit and bigger tires (and hopefully mud flaps) and nerf bars and tinted windows or a custom paint job but leave the emissions systems alone.

It doesn't take long at all for a DPF delete to pay for itself with the cost of urea what it is.

[MikeNH]

While my emissions system is intact and I have no plans to change that I do not feel the govt has any right to dictate what I do with my truck. That is just a power they assumed, and no one stopped them.

 

 

And full auto firearms and suppressors are indeed legal in most states. Expensive and complicated to obtain, but legal. ;)

Yeah that DEF stuff is a price point killer!! Last time I checked mine the Def fluid added about $0.0025 per mile for me to run my truck. So at that rate it will take me about 480,000 miles of driving and then it will have cost the same as a delete kit for my truck. I plan on having it for a very long time but I am not sure if it will be that long or not.

3% LOLOLOLOL....dude my truck gained 4mpg ripping egr and DPF off. You can gain almost 40% RWHP with just a tune, nobody takes it off for power gain.

 

It's not about gaining anything anyways, you need to realize how they work in the early ones. It makes the rear two cylinders dump extra fuel on the exhaust stroke so it dumps raw fuel into the DPF. Ignites it and makes the soot burn up more complete, people

Rip them off because its super hard on the engine, turbo, injectors, cp3. The new urea is a better design, still plagued with problems tho.

 

They make zero sense, they run cleaner but make you burn 4-5mpg more. Makes no sense. They will always sell straight pipes and tuners.

 

nobody will stop.

 

:-D

It's the owners choice to do whatever he wants with his investment.

Good luck getting 480k out of a DEF equipped truck. It will cause you issues loooong before that, probably just after your warranty is up! if it was me I would have the egr/def laying on the floor to protect my $70,000 investment!!

[doverarjim]

Chevyboy, that is my point. The cost of the DEF will not make a bit of difference over the time that I will own my truck. I can save money by not removing the system from my truck. I will need to drive the 480,000 miles to spend the same amount of money in def as what it will cost for the delete kit. So why do it???
