help on dpf delete information

[SStrano]

I'm having a hard time sifting through all this DPF delete stuff and was wondering if I could get some basic questions answered.



It seems there are a few different kits from different folks.



Do they all get rid of the DPF only? Do they dump the cat too?



How does installation vary? It would appear that some have ready made sensor replacement, some don't. And some are ready to bolt-on, some aren't, is this accurate?



And does anyone yet have a setup that keeps CEL's from coming on?



Finally, it seems from all reports the DPF is hugely restrictive (not that I'm surprised since it can catch soot). Mileage gains look big in all the cases it's deleted, unlike the claims you often see with boxes, etc. Is that pure assumption, or have others noticed this?



Thanks... . been a great source of help so far!

I will try and answer you in order. First, No some kits get ride of DPF and Cat wile others just get rid of DPF. From what I can gather, both companies are making plug and play kits. I still think that the Houston based company sells them with out. I bought one of the first kits and had to go to dodge and spend 150 bucks on egt sensors, but I replaced all three. Next, I am not aware of a kit that keeps the CEL's from comming on. You can get the edge with attitude and it will clear codes on start up, if you want. Finally, as far as restrictive, I have a picture of my mag lite shinning on one end of the DPF and you can see nothing on the other side, it is very restrictive. My MPG did increase, but no more that 3MPG, but I drive like an idot. I saw the most MPG gains when I put on the complete AFE intake. Like I said I drive stupid and I get 15. If I drive normal i easly see 18's, but what is the fun in that. I have a 2007. 5 4x4 quad cab and oversized tires. The other thing, is that when the DPF is gone the jake break works better for me, I dont read anything about this, so it could be in my head. I hope this helps.

Well for the mpg mine only changed about 1/2 a mpg but my truck is stock other then the above part. I will have to get an intake and see if that helps. and I don't drive to hard on it.

Hi. H&S makes a kit with all you need for the change over, EGT sensers and bungs welded in place. there is also a down pipe for there kit. Dont know for shoure but was told there was a Cat in the down pipe that was very restictive. If Diesel Lady comes on , She has the H&S 5" and can give you some real time reports. I will be ordering one in a few weeks but have not made up my mined if it will be down pipe back or just cat and DPF. replace.

you will need somthing like Juce with Att. to clear codes at start up.

I thought the Juice with Attitude wasn't available for the 6. 7 yet. Are you using the one for the '07 5. 9?

 

[Harlan]

The Juice & Att. is available for all 6. 7s.

call Edge and they will tall you or go to there web page.

Cool, it's been a month or two since I went to their site. I see it now. I want one, but I think I'll wait a bit until all the software kinks have been worked out by Dodge. I don't want to void my warrantee just yet.

 

[RVanWagnen]

HAAAAA HAAAAA!!!!! im not sure arround you, but here by me with a cummins powered truck the dealer will void your warranty just for leaning on the counter wrong! These trucks might as well not even come with a warranty... .

 

[HLewallen]

So, what happens to the regen cycles with these kits? Do they just simulate a PDF that never hets clogged, or do they simulate something rational? Do the kits also include EGR block off? Has anyone verified whether the DPF is covered by the emissions warranty, or just the 3/36 warranty? If it was only currently covered by the 3/36, that would leave me to believe it is not considered an emissions component until the 2010 regs com online. It might be a good reason to ditch it, or a good alternative after your warranty expires.

We just put a H&S 5" turbo back on my buddies truck, so far he likes it, you do get a CEL but it does not go into limp mode. I'm pretty sure you can run lsd with out hurting anything too.

 

[LMangold]

Extra sulfer can't be good for the EGR and exhaust brake which will build extra carbon at a faster rate.

What's so funny? I don't get it.



The extra soot from the LSD will definatly not be good for the turbo, and of course EGR.



If you delete the DPF, plug the EGR, but, DO NOT plug the EGR, if you DO NOT remove the DPF.

The Best DPF Hit My Door TOday - Dodge Cummins Diesel Forum

look at the first thread, there are links to pictures from the BADP system, they modified a magna flow 5" exhaust for a 5. 9. they also have a 4" system that they make, delete pipe for the DPF and 2nd Cat, and a down pipe to delete the 1st Cat

LSD diesel, thats so hard to find. Its been said that its not even made anymore. not sure how true. but i have seen where passenger pumps have ultra low stickers on it and then you go to the pumps for the semi's and it has a low sulfur sticker on it.



removing the dpf, you will less likely plug your EGR. with the DPF in place you are holding that carbon in the EGR longer rather than just flowing it straight out with no back pressure. but if your scared of plugging the EGR, then just block it like so many others have. Just think 100% clean fresh air going into the engine, that would be crazy.

Extra sulfur in the fuel will not produce more soot, but extra sulfur will damage the NOx Absorbing Catalyst (the can in front of the DPF). If this is removed I don't think you'll have any adverse affects of running LSD. I'm pretty sure the H&S takes this out of the picture as well as the DPF.

 

[PaulBarker]

yes you are correct it is removed with H&S and the BADP Kit

From what I hear, Mexico still has LSD.



You will ruin your DPF if you plug the EGR. DO NOT JUST plug teh EGR. You have to delete the DPF, and plug the EGR, or just delete the DPF.

i am not sure where this 3/36 thread started but dpf is part of the 5/100k emission wty. i just verified labor op. 11500139

Mexico is not the United States, Not worried about them. I am sure you buy LSD in Africa and in Asia too.



You would destroy your engine if you block off the EGR with the DPF inplace. Your EGT's will get way to hot when it regens. The DPF would be your last concern. But i think you misunderstood me. Its ok, it happens.

 

[PaulBarker]

I was not very clear on what i was saying, i assumed people know you have to have the DPF off when you block off the EGR
