Bombing a 6.7

[MulesHemi]

Just reading in my newest edition on Diesel World, (date says april 2007)
theres an artical about a 6.7 chassis cab that bully dog put together.
They did a lot of show items but it mentions that they added there

"Bully-dog 6 inch exhaust, Rapid flow intake system using bully dogs latest deisgn featuring a sealed air box for cooler air temperatures and there Performance Managment Tool that adds 155hp while monitoring engine functions, readings and parameters through a four color-screen. The estimated power totals for the combination are about 415hp and 994 lb-ft of torque at the rear wheels, according to bully dog"

also...
"after driving around bully dog's ram for a few days, a few things became apparent. First off, the new 6.7 is a MONSTER. There are going to be a lot of happy dodge enthusiasts come early '07..." and goes on to praise the rear view camara ect....

:rck: 415hp and 994 lb-ft of torque :D

some pictures of the truck and new monitor :rck:

I read the same article, you still want to buy my truck????

I think I'm going to start working on my order sheet and option package so I'm ready to go truck shopping, I figure since the Wifey got a new 300 this year, now it's my turn. I'm still pondering long box/ short box, I have to remember te 5th wheel and how easy it can cave in the rear pillars on the short box. Have the color options changed on the 6.7's??? It seems like I just bought my 04' last week. hard to beleive it's been two years.

I wonder how much work they are going to have to do after the regular 6.7 is put out. The cab chassis 6.7 is a different breed from the other 6.7 that is going into the rest of the trucks.

[MulesHemi]

thats true but I'm willing to bet the only diffrence is the computer program

[bobem12]

sounds like good news....I think. Although the chassis cabs don't have the 'special' (for lack of a better term) exhaust on them do they?

[Josh Brown]

It produces power but how reliable will it be is my question. I can't imagine a 6" exhaust on a rig with little mods, I'd like to see the dyno sheet, I bet all the gains are Higher in the RPM range and I bet there is a loss of power at lower RPM.

Bingo, we have a winner. there are many differences in the cab and chassis and the regular ones including the cab and chassis isn't 2010 ready like the other ones are. There is also 45 HP difference in the engines. The cab chassis has a 305HP/610 lb-ft of torque engine and the new 6.7 is 350HP/650lb-ft of torque.

But that could EASILY be computerized de-tuning

I'd like to see the dyno sheet, I bet all the gains are Higher in the RPM range and I bet there is a loss of power at lower RPM.

So would I, all I know is what i read in that artical

[Ram3500Dually]

There is a reason the Cab and Chassis have been out for 7 months and the new 2500/3500's are being held. The engines are different, its not just computerized detuning that is the difference.

[MulesHemi]

whats diffrent about them? i dont know but id like to

[Ram3500Dually]

Nobody knows because they haven't been released yet. Thats why I find it hard to believe Bullydog spent all that money on R&D on something that isn't likely to sell because there aren't alot of Cab and Chassis's being bombed.

[mojoman]

daklover, that is one nice truck.

[MulesHemi]

well then wouldnt it make sense that all there stuff would be interchangable with the 2500/3500 trucks? since we KNOW that one diffrence between the two trucks is the output rating, and we KNOW that the lighter duty trucks are being held back due to a programming issue, couldn't one assume that the only diffrence is the program?

Its just my theroy but, say the program for the lower power chassis cab is diffrent from the one on the 2500/3500...they havent fixed the exhaust filter bug on the program for those trucks so there not releasing them.....does this make sense to anyone else?? It makes perfect snese to me

[Ram3500Dually]

The cab and chassis doesn't have the full egr on them. They aren't 2010 compliant. Can I make that any clearer? It is NOT just a program difference.

[MulesHemi]

If you would have said that in the first place I wouldnt have opened my mouth...er keyboard

I think I did say it earlier...........

[MulesHemi]

ok you win, your a moderator and im not.
back to the interchangeabliity thing though, I would deff. count on most if not all the stuff mentioned being available on the 2500/3500 models

It sure seams like Ram dually 3500 has an answer for everything! Why don't you give us all the winning lottery #'s for Wednesday, and we'll all buy a new Truck.

[Ram3500Dually]

What was that link supposed to show me?

And I forgot, you have worked for DCX for 29 and a half years and have been driving CTD's for 17 years. Oh wait, thats me................

[MulesHemi]

Ill shut my mouth, only because I'd rather not argue over something we both KNOW nothing about

this piss contest is taking away from the point of this thread...the hopped up 6.7

[me1magoo]

I'm curious, what's the "full" EGR? The chassis cab 6.7L that I had in my shop and had my hands in had EGR ported from the exhaust manifold to a throttle body on the intake. What more is there to Exhaust Gas Recirculation? Please explain because I am obviously ignorant to whatever is being done special or different. I understand that there are "differences", but what are they really? The chassis cab had the particulate filter, but maybe it operates differently than the exact product that is going to be installed in the pick ups? I don't doubt that there is something different, that's clear since they can't get the pick ups out the door and the chassis cabs are already on the road. OR, did they release the chassis cabs immaturely and now will have to go back and get them fixed and figured that the lower quantity will be easier to recall and get corrected than the mass flood of consumer non commercial pick ups???? I just don't see why they would build the engine and systems to be compliant THROUGH 2010's improvements and only put that in the pick ups now and NOT in the chassis cabs now and then hold the pick ups, are they not compliant with current requirements? If not, then how are the chassis cabs compliant? Sounds like something else is amiss here, either DCX is not telling the whole story, or they have goofed and are covering it with this emissions equipment not meeting requirements bit.

Wish there was a emoticon for "stir the pot"!

[Ram3500Dually]

Since I have not seen a 6.7 I cannot answer that. One of our engineers at the R&D center was the one that told me what the problem was when I was over there checking something out. He said the new 6.7 in the cab chassis was compliant for the new rules as of Jan 1st 2007 but was NOT compliant with the next set of rules going into affect on January 1st 2010, but the new 6.7 going into the other pickups is already compliant to 2010. He said it is a different EGR system, different computer system and some changes in the exhaust. You can take it for what it is worth but since the other trucks haven't been released yet, he IS and engineer at DCX, he WORKS in the Research & Development building at DCX, I took it that he knew what he was talking about.
I personally am as lost as the rest of you on it.

[john.colorado]

sweet... i want one

[ahimsel08]

what do you mean by 2010 compliant?

[Ram3500Dually]

what do you mean by 2010 compliant?

The government came out with new laws for emissions that started on January1st 2007 and the laws will change again on January 2010. That is the reason DCX quit building the CR Jeep Liberty, it couldn't pass the new 2007 compliant laws.

[six pack]

Anybody else notice that truck has only got one battery hooked up?

[MulesHemi]

your right....wonder why

[me1magoo]

OK, so again, until we see a new one we are gonna be stuck wondering. Oh well, no big loss. I hate waiting though and am trying to get more info about it all. I hate that they are stepping on their own toes with this roll out, really makes it look bad all over, but I'm glad they're holding them instead of just delivering and then trying to hunt them down to fix it later like SOME others have!

[LS1POWERED]

Now now play nice kiddies. lets keep it friendly.

Ram3500 is correct, i remember reading somewhere the chasse cab does not have the DPF crap there to clog up the exhaust. I do wonder if that will be the new trend, buying the chasse cab with a pick up bed to dodge the epa junk.

im glad i picked up my 06 when i did, although i do wish i had a 6sp auto.

[MulesHemi]

Ram3500 is correct

SURE, take HIS side, great......

lol, j/k if im wrong them Im wrong, I just like knowing the facts, and having proof, not speculation and guessing and, Well my buddy whos the dealers cousin told me.......

[Ram3500Dually]

And an Engineer that works on these things for his job is not proof enough for you? Did you not read I said One of our engineers at the R&D center ?

[pyrokid]

Oh those pooor new emission compliant engines!!

[MulesHemi]

damn, chill out, I wasnt talking about YOU, or what YOU said, what I said was just a general thing, not towards anyone in particular

[Budman_Kunz]

Ram3500 is correct, i remember reading somewhere the chasse cab does not have the DPF crap there to clog up the exhaust.

If it doesn't have a DPF on it then what's that big cannister hanging off the bottom of it in the first picture? :lurk:

[Ram3500Dually]

Its not a full EGR like the 2500/3500's will have.

[moparedtn]

The entire tone of this thread is alarming.

If all we know is bits and pieces of what this article says or that engineer states, then obviously the whole story isn't public knowledge yet.

That's all well and good, of course. Sure, many of us are waiting for the 6.7 to hit the streets. Sure, we'll all have our sources and opinions and such.

However, there's no call in being rude and condescending; especially not welcome from a moderator, who should be the "better man" in any such debate.

I hope the tone of things will calm down so we can get back to what this site is about.
Pissing contests, by the way, are not on the list of features of DT.

Thank you Uncle Mo!! I'm pretty sure that if you look in the dictionary and you look up the word " Moderator" you wont see "God" or "Know it all" next to the word as a definition.

[me1magoo]

Guys, I'm trying to shed a little light that I have. I have seen the 6.7L in the Chassis Cab truck. I have had the intake apart and have personnaly turned the throttle body (motor w/ door to allow air into intake from EGR cooler) to allow a clutch pump to be installed. It does have a large "catalytic converter" looking thing that I ASSUMED to be the particulate filter based on pictures and descriptions of such said beast. It does have the decals, warning lights and instruction tag and information in the manual describing the particulate filter operation and proper maintenance and corrective action if it becomes "full". That's it, I am hoping to hear how EGR is more than exhaust gas ported from the exhaust manifold through a cooler and then into the engine air intake manifold now which is exactly what was on this engine. I do not disagree that there may be some programming differences, but when I am told- "It is different", I expect to also hear "this is how", not just "cuz I said it's different". Thanks for any discussion, though, it's not personal, we are just discussing our ideas and thoughts.

Ok guys here are some pics of the new p/up 6.7L engine

The first pic shows the actuator for the valve in the EGR piping. So I'm going to say it's the p/up engine that does not allow EGR at idle.
3rd shot is of the shifter for the new 6spd auto and the 4th is a picture of the button for the exhaust brake.

Driving impressions; This truck is waaaayyyy quieter idling and driving at Hiway speeds. The transmission shifts very nicely, not quite as firm as the 48 under normal throttle and extremely smooth under WOT. The exhaust brake works very well, much better than the Mopar add on kits for the 5.9's.

I can't wait for my truck to show up now, supposed to get loaded on a railcar tonight.
