looks like i toasted the turbo saturday

[lil red cummins]

truth be told, i have been really conservative with the BOX since i was waiting for the gauge cubby to come, and the pyro was not permanently installed. it was hard to see in its temporary position when driving. daily i drive at 2,2 and love it with an occassional 5,2.

well, i installed all the gauges, finally, last week. i had tried 5,5 and all seemed well. power was incredible. i turned it up to 9,5 and only ran it full power in 6th from 50 to 90. shut it down because the front of the truck actually felt light with the acceleration! total time in the throttle seemed like around 5 seconds. i glimpsed at the boost which was at 38-40. never did get a good look at the pyro. i assume it was over 1000.



anyway i noticed today there were strange "harmonics" in the sound of the turbo as i was driving to work, so when i got home tonight, i pulled the intake off to check it and found metallic particles imbedded in the intake area. the exhaust side is fine, no marks or heat distortion. i can easily push the intake impeller sideways into the housing to bind it, however it does still spin freely without oil pressure as long as i spin it and let go. doesn't look like any particles made it downstream to the intercooler. i checked with a light and a rag.



so, since i am my own warranty station (truck will be 1 year old 12/27) and i was going to upgrade the turbo anyway, (even though i wasn't planning on doing it so soon), i need suggestions for a bolt on replacement. i read a few threads mentioning the B1-04 and others. i am probably not going beyond what i have now in power, except maybe alcohol/water injection. this is a daily driver and i am happy with the amount of power i have already. since it is a stick, quick spool up is important. seems like i spend more time in a gear waiting for spoolup than once it is spooled.



please suggest away either in this thread or PM me. the turbo is on the bench and the truck is down. also thinking about e-brake too. not trailering now, but may pull a TT in the future.



thanks

HMMMmm - Internet photos CAN be deceiving - but *I* sure don't see the scrapes and scars at the vane tips and adjacent housing I would expect - I sorta wonder if maybe the turbo ingested something from upstream that created that debris?

Wondering the same thing here? The noise I can't explain but why would the particles be outside the turbo on the intake side if they came from inside? Sideplay in normal in a turbo shaft as long as it doesn't touch the sides, what do you mean by "make it bind"?



The only direct bolt on that will recieve a direct mount exhaust brake is the B1 line for these trucks. My Killer B2 bolts up direct but requires a diffrent downpipe and I had to modify the intercooler tube slightly.

Leftover goo from pyro install?

 

[lil red cummins]

talked to a knowledgeable person today, and he suggests that i may have barked the turbo (spun it backwards) and that may be why there are particles "ahead" of the compressor. seems like a reasonable explaination. the intake system is stock.



these particles are imbedded by the way, they do not just brush off. i had to dig at them with my fingernail to remove them. it looks like they were deposited at high temperature, as if the air was shooting out the inlet while the impeller was digging in the housing.



as far as "making it bind", i mean that if i push slightly sideways on the nut and try to rotate the impeller, it will not. the bearing is loose enough to make this happen, which i understand with oil pressure, may not be the case as the oil will float the shaft to the center of the bearings.



right now, the best bolt on option i have discovered is the BD super B. are there any other suggestions?



scott:

do you like your killer B2? how much modification did you have to do and how much time did it take?



thanks

I am running the Diesel Dynamics Jammer turbo and pipes to make it a direct fit (on my 2004), and the afe filter with their box. It has been on over a year and has done very well, even at higher altitudes. I don't have any direct experience with the other options, but I am happy with this turbo. And, many of you know how many turbos I have gone through on Sickly, my 97

wrong side of the turbo for that... .

 

[Gypsyman]

If you want to run the Jacobs then the B1-04 is the way to go. Excellent spool-up on my 6 speed and an excellent fit. If you go with an inline brake you have more options.

I'm happy with it thus far. Much stronger than the stocker with spool nearly as fast. Don't expect zero egt issued with it and a TST, it's still hot but you have to get up to level 5 before it becomes something you need to watch. Can't touch 1250° on 4:4.



Install took me about 7 hours. This is including install of a new ATS manifold, building downpipe, modifying the intercooler pipe, and installing a 4" inline Pacbrake. My understanding is there is no need to modify the intercooler pipe with the stock airbox, I have the AFE Megacannon. The oil supply and drain will swap right across and the turbo will bolt up to the manifold just fine (but you will need a couple of bolts w/nuts to replace two of the original studs).

lil red cummins,

Hey Lil' Red... what will happen to that old turbo when you've replaced it?



-Ryan

 

[lil red cummins]

good question ryan,



i haven't decided yet. i was thinking about taking it apart and seeing what it would take to make it right. but as of yet i have not made any decisions. needless to say, it is not useable in its current form.



what ya got in mind?



by the way due to the additional cost of an e-brake, i am probably only going to do the new turbo at this time. e-brake may come sometime next year.



so who is a BD distributor? i understand pricing may be different from a distributor than from the factory. don't want to step on any toes, so please PM me if you feel it is appropriate.

ut ohhh, Ryan is looking for some toys to play with :-laf

I just think it would be really cool to take apart and display the parts on my desk at work. Right next to the 5. 9 connecting rod I already have! [I get lots of comments on that rod and it generates a lot of discussion].

Look into the bd super b it works with the bd turbo mount exhaust brakes I have one on my o4 it will handle 450hp Bd is pretty protective of their design this is all they would tell me as a vendor the housing is around a 16cm and they use a small impeller with extended fin just a imagine a impeller and the end of the tips are extended small impeller helps it spool up like a hy9 holset but extended fins deliver air above the capabilities of a hx 40 it really is a sweet design. Bd engineers designed this impeller and schweitzer delivers the product you can pm me for the price lil red

 

[Loaded 45]

I will second the BD. Super B - cheap in price and one year warranty.

Spools fast & egts way more controllable. Easy to install , If you had good tools you could probably do it in 2 hrs or less. The 4 manifold bolts suck.

5X5 + fueling module used to smoke like you would not beleive - now same settings with the BD turbo - pulls way harder & barely smokes - For the price you cant go wrong. - Good luck!

What exactly does "bark the turbo" mean? Would that account for the occasional noise I hear when spooling the turbo up on a fast acceleration and shifting gears. Is there any harm in that? This usually happens when I'm pulling heavy.

 

[BCarmicle]

You are most likely hearing the wastegate open that lets boost out when shifting gears.



Barking the turbo is when the turbo is spooled(spinning) and you let out of the throttle fast and the turbo tries to stop spinning. You will know if you hear this sound and can be damaging to the turbo.

BD Power Super B Turbo, love mine!



BullyDog Power Pup on EXTREME, Edge EZ on 4, stacked. Handles everything just fine. EGT's are very managable, very quick response, and quick cool downs. Lifts front end off the ground just enough to loose steering.



Highest EGT's are 1400 with 40+ pounds of boost at WOT. Fuel pressure running 17 lbs.



Cruising at 70mph, EGT's at around 750-800, fuel pressure at 15 lbs. Very responsive from a roll, hits 100 mph in a blink of an eye.

Any issues with barking the super B??
