Lost my Turbo

[DRuehlman]

So time has finally come to upgrade the turbo. It appears I have dropped a bearing in my stock turbo or at the very least something is very wrong.



My turbo whine sounds like fingernails on a chalk board now.



So My question is what turbo is best for my situation?



I do tow about once a week, at times heavy (+12K #'s) and over long distances.



My vehicle specs are as follows:



2004. 5 Ram 2500 4x4 Quad Cab

4" lift

325 75 R18 Nitto Terra Grapplers

AFE Intake with torque tube stage II

ATS Arc Flow intake

ATS Pulse Flow Exhaust Manifold

Hog Performance 4" turbo back exhaust

Pure Flow Technologies Air Dog II DF-165

Triple Dog w/ Outlook Monitor

Van Aiken's Torque Dog Module

DTT Transmission built for 1200 ft lbs

Fuel line pressure, Trans Temp and Mechanical boost gauges



I think that is all, but if i remember something else I will include it.



Thanks in advance,

Dave

If you tow try in stay with 62/12/71 2nd option 62/14/74. What gearing do you Have 4:10 / 3:73?

 

[DRuehlman]

To tell you the truth I am not sure on the gearing. I can't believe that I am actually saying that. Is there anyway to tell with the VIN# or a door sticker? I have my truck at my mechanics shop for now so I am out of luck to do the research at the moment, but I do have some paperwork available to me at my house.

When you are referring to "62/12/71" what are you referring to?

Also, I have seen some really high EGT's in the past, I know turbo's help with this but how much can I expect?

For some baseline info, before the triple dog, arc intake, ats manifold, and dtt trans, the truck had a dyno run of 407HP and 787TF #'s of torque. I haven't put it on the dyno since the other mods.

 

[DRuehlman]

Spoke to my mechanic, it has 3. 73 gears.

 

[TCDiesel]

The glove Box has the gearing, 62 is the compression wheel size, 12 is the exhaust wheel size, 71 is the exhaust housing size. When you spec out the huffer you need to match it with cam,setup,TC,use,In others words YOU really need to know what you're doing.

I realize it is important, that's why I am looking for direction.

Thanks again for all the help so far.

TWest, your mistaken , 12cm is housing, 71mm is turbine wheel , and I would never recommend a 74mm turbine wheel for towing... . unless there's a whole new, much tighter housing, being offered to help in spoolup.



I would stick with a 62/65/14, or a 62/71/14 (62/71/13 SS, if you want to spend the dollars on the stainless housing). My . 02

Yep... . Thanks for the correction. I always consider 4:10s as the prefer gearing for any long term towing and city driving,I had the 65 with 4:10s it screamed on the low end . It really suffered Mid to Top. 3:73s is what kills the spool when towing. Its so overlooked almost get flamed for mentioning it,I city and Hwy drive and tow. I can't even remember the last time I had another Gear ratio. I don't drive fast,I just like to get up and Go. I wonder How Much Top would I guy lose with 62/65/12 vs 62/71/14 and 3:73, My guess the 71/14 would suffer on the Bottom and Top (4th Gear) and great in the Mid,the 65/12 would be OK on the Bottom thru the top.

From what I have read, the 62/65/12 is close to the factory turbo but will provide the most across the board, bottom thru top, with a little lower EGT's and light up a little faster. Those who went with a 64/65/12 talk about it having lag, and a lot of lag when towing.



I replaced my stock turbo with a 62/65/12 before I went with twins, it lived up to what I had read about it, it was a good matchup to our 600 engines, and def a little perkier than the stocker. It did lower my EGT's but not enough to suit me, so I went to towing twins. I use my truck a lot for towing, I tow heavy, so my goals might be different than yours.



I have the 373's like you do, but I have the G56. The transmission makes a big difference also. My stick could have handled the 64/65/12 but I do know that the auto trannys have had problems running them, just too much lag.

How much could I expect my egt's do drop with the 62/65/12?

I can hit 1650 pre turbo if not careful, Is there something else I should be doing also to bring them down?

Obliviously I don't do this but with everything on its not difficult.

Sps62

DRuehlman, My first turbo after my stocker was an Industrial Injection SPS62(62/71/14), it was a great turbo for towing and keeping egt's in check.



Do a search under post's by JStieger titled "Prototype" Super Phat Shaft 62!!!. It is an old post so check "any date" while searching. It is a fantastic write up, and sure to help you out.



Found it for you, Jess

That looks like a pretty sweet set up, I would suspect it would react similar on my rig with the two boxes I have. No injectors though.

I still had stock injectors while running that turbo, TST/03 Twins, stacked with an Edge EZ, was a great combination.



HTT has a similar charger, 62/71/13cm Stainless Steel housing, more $, but I would believe even better performance, quite a few folks running it. It is very hard to get a single charger to perform well throughout the power band, quick spool up, plus flowing enough air on top, too keep things cool. These 62's work pretty well, as long as you stay with a 71mm turbine or smaller.



I understand BD is having good luck with their Super B Special(64/71/14), however I have no first hand knowledge, I do know, most folks who try and tow with a single charger that has a 64 or 66 mm compressor wheel, experience too much lag along with surging at certain rpms.



I believe you are following the correct process by researching, so you can make an informed decision. Good Luck, let us know what you decide.

Does anyone have any opinions of ATS, specifically the wastegated Aurora 4000?
