Title says it all. Are the stock Duramax chargers, particularly the LB7 models, on a pedistal that attaches to the manifold or are pedistals just used for upgrading to aftermarket chargers?
Thanks

Are stock chargers on a pedistal????

Need to know 100% sure, cause I was "pretty sure" also but am trying to verify before I use that point in a discussion.

I think the stock chargers have the pedestal molded into the turbine housing. Unlike a cummins that has a standard flange, the duramax chargers can only be used on duramax's unless you change the turbine housing.
See how PPE made the pedestal in this picture, well that part is attached to the stock chargers, IIRC.

Yes, it is integrated, I remember looking at my stock turbo, and it had a pedistal that was on the exhaust housing.
No They are not on a pedistal that is seperate. The exhaust housing of the turbo is the pedistal for the factory charger.
That's not the only thing I Cut. No sensors left (MAF, Baro) who needs'em. The stock turbo assembly weigh's at least 45 lbs. and look's like a toy compared to the A5K, which should be spinning again fairly soon.you couldnt get those hoses off so you just cut them i see
Well this is not good news. I have mentioned the 2.5" rules around here for pulling. Associated with this inducer limit, there is a "NO adapter plate" rule as well. This part of the rule eliminates us (LB7s) from also upgrading to an aftermarket 2.5" charger. Thats gonna make it tough to keep up with built Cummins' with nice efficient 2.5" chargers. Oh well. Such is life I guess. I was trying.

The diesel shop is open. Let' take it easy and only go with twin turbos and triple CP3'sMaybe both our trucks will be up soon. After this mess I just may build a motor
:yup:
Dodge guys.:rofl:
Honestly go talk to your local pulling mafia. Most do not know that the Duramax is a intergated mount. The DHRA was going to outlaw adapters to try to keep out BIG chargers. I brought it up that that would screw the Dmax guys. They just did not know. That rule is a older one. Basicly what most mafias want is a mount flange no larger than a T3. The do not want a T3 to T4 adapter or a T3 to T6 adapter. If you talk to your local mafia about why we need a pedistal I honestly think they would understand.

I ahve asked for clarification. He just keeps saying "Read Rule X" and won't say yes or no directly. Don't understand why he's being so difficult. Actually I do; he's just always this way. You have to guess what his intrepretation is and if you guess wrong after asking him and show up to pull, you'll be sorely dissappointed cause they tech pretty good there and you will not pass if you haven't met every rule the way they see fit. So the guessing game is a bit frustrating. All in all though, the rules are pretty fair. I love the 2.5" rule IF the older Duramaxes can also upgrade to that as well. Its a happy medium between stock charger class and the, now insane, 2.8" class. Shouldn't *have* to build a motor to pull in it and you still get to do some of fun things like upgrade cahrgers. :angel: So by in large, I'm all for it. Again, provided the older Duramaxes can also upgrade to 2.5" chargers. IF NOT, then a retrofitted LBZ charger is the ONLY thing that is legal per the rules cause you are allowed to use chargers off of different model year trucks. He apparently spoke to ATS and other "Duramax Gurus" and they apparently informed him that the LBZ charger is as capable as most any 2.5" charger on Cummins due to programmability and better flowing heads and such. I'm not buying into that a whole lot but oh well. One guy commented that he knows where a 2.5" charger is that can flow more #s/min. than an A5K. :crazyeyes:
It is very clear why they have set the rules the way they have. They'll even tell you why. It IS to allow the Dodges to run approx. the same sized charger as the newer Duramaxes. It is the entry level class, meaning there is NO stock charger class where all makes have to have stock chargers. Just this one where apparently the Duramaxes (all years) have to remain stock. What ever their ruling intrepretation is, its set in stone for the season. Perhaps I can get to their rules meeting for next year and get the adaptor plate rule changed or a clause added that will at least allow the old Duramaxes to upgrade chargers.
Thanks for y'all's help. For the record, this is the same guy that was in charge of the Diesel Power Challenge East truck pull and is also setting up the TS Performance Truck Pull (will be the same rules at TS's event except DRUGS ARE ALLOWED).

I'm not complaining, just explaining the way it is currently.

Rediculous. I guess the people who already pull are used to this, but for me just getting into it, it is kind of frustrating! There should be a stock turbo class like Mitch said if they want to be that way.
This may be a stupid question, but what is our stock inducer size? Which turbos go up to the 2.5"? 2.8? Is a gt 4202 2.5?

I believe the LB7 inducer is somewhere in the lower 2.4" range. The exact number is slipping me. The LLY is like 2.51x if my memory serves me correctly. The HTT GT40 turbo, according to a friend with one is in teh 2.6" range. I'm not sure about other GT40 series chargers. The A5K is really close to the 2.8" size. Again, I don't know its exact size but they are used a lot in that class. The 4202 I believe can be larger than 2.8" depending on housings but there again, I think they are being produced to target the 2.8" limit of things. the "02" part, in my understanding is in reference to the 102mm exhaust side.
I get rode pretty hard for arguing about rules and stuff on our local board (our site is a mix of trucks but is predominantly Dodge) more so because I have never pulled yet. I understand their frustration in that but that doesn't mean I don't have logical thinkig just because I don't pull yet. Now that I am planning to pull, I still get rediculed even for asking these things. Oh well, what can you do. There are some TOUGH CR Dodges here that I likely won't be able to beat even if they keep their factory charger. They give our top Dmaxes a run for their money at nearly every pull they went to. Theres also a 12V that has a built motor and runs a 2.5" charger that is very tough to beat as well.
I might give it a go at this pull just because it is the nicest track around, the crowd is awesome, the techs are pretty fair in their judgement (even though they take twice as long to tech GMs) and it'll let me see where I stand against these trucks. Perhaps a little trump card I have up sleeve will help out if I can get the money together in time to get it done. It should even the field a bit even though I won't have a larger charger.
