Variable Geometry Turbos for Dodge Cummins

[PeterT]

For those of you interested in variable geometry turbocharging for the late model Dodge Cummins, be sure to watch Xtreme 4x4 on the Spike network the weekends of March 5-6 and March 12-13. The show airs both Saturday and Sunday at 1:00pm Eastern. You will see a variable geometry turbo installed on a 2005 truck.

VGT Turbo

Peter,



Obviously this is a Banks Turbo,. . right? Will it require an upgraded Intercooler? Do you guys market a set of twins for say a 500HP + 04. 5? If yes, pls provide me contact info and tn to whom I may speak regarding same.



Tks,



Pat

i'll need to remember to set the vcr up... thanks for the heads up...

 

[PeterT]

Pat,

Yes, this is a Banks Turbo. The duct work is designed to work with the Banks intercooler, which also incorporates a High-Ram intake (you’ll see that on the show as well). For production purposes we are going with the versatility of the variable geometry over a twin or a compound turbo setup. We are achieving over 500 HP with the VG with excellent drivability. The only twin setup that we are involved with is a marine version that is making about 750 HP.



After the show airs, our sales reps will be equipped to handle any questions regarding the variable geometry turbo. The unit that will be installed on the show is a prototype, production units should be available within about 6 months.

Will the turbos void our factory warranty?

jwilliams3, I think you're just a tad beyond that worry... :-laf

 

[PeterT]

Jwilliams3,

The products that you will see on the show, including the variable geometry turbo, fall into the category of racing products. In any of the literature that accompanies our racing products (Six-Gun, Big-Hoss Bundles, etc. ) you will find statements that indicate that when these products are used, the vehicle owner assumes responsibility for all warranty issues. The reason for this is that these are products that a customer could potentially use in an abusive manner.

How can I buy one?

How can I buy one?

And what do they cost?????????????????????

 

[Timbeaux38]

And what about the 24v 98. 5-02 truucks?

The only twin setup that we are involved with is a marine version that is making about 750 HP.



I like it!

KOOPDADDY,

After the show airs you can contact our Sales staff and they will have some info about when the product will be available.



GWoody,

Pricing is far from being set at this point, but it stands to reason that it will be less than a compound turbo setup.



Timbeaux38,

Functionally the turbo will work on the 98. 5-02 trucks just as well as the 3rd Gen trucks, but we may need to do a separate exhaust manifold casting to get it to fit in the truck properly. We have been discussing how to make that happen.

Downpipe

Peter,



Will this turbo have a 5" downpipe? Do you have any maping or other specs on this turbo you can share?

 

[PeterT]

OT-OF-HERE,

The turbo has a 4” turbine outlet pipe. About all I can tell you right now about the turbo is that it is a Banks-Garrett hybrid variable nozzle turbo that is capable of about 500 HP and 1000 lb-ft, but is still very responsive for day to day use. We are calling it a ShapeShifter Turbo.

Peter,



Since it sounds as if your still in the planning stages with prototypes, maybe you could look at a downpipe that would flare to 5" for better flow. Pls consider it. Also , for this turbo to do its best job would you need to upgrade the intercooler? If so, will that be covered in the TV presentation and advise the % of flow increase that would be obtained. I suppose you'll have a package for this upgrade to include all the goodies necessary. Tks.

Make It Work With A Turbo Mount Exhaust Brake!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[PeterT]

Pat,

The turbo currently has a 6-bolt flange on the turbine outlet, so any custom exhaust could be made for the turbo, however, I think it is valid to point out that a 4” exhaust is sufficient for more power than this turbo will deliver. The Sidewinder Dakota engine produces 735 HP and 1300 lb-ft torque with a 4” diameter exhaust. An upgraded intercooler would definitely be recommended for use with this turbo, you will see one of those installed on the show as well. Intercoolers cannot be properly evaluated just based on flow. You need to consider both temperature drop and pressure drop when discussing an intercooler’s capabilities, and the result is an evaluation of its efficiency. The Banks intercooler is about 10% more efficient than the factory unit, which means that it will allow for about 10% more power at the same EGT than the factory intercooler.



FDavid,

Since this turbo is considered a high performance item, we most likely will not design a direct mount brake for it, however since it is a variable nozzle turbo, it is not out of the question that we might be able to control the turbo in such a way that it actually acts as a brake when we want it to by closing the mechanism down and restricting exhaust flow.

FDavid,

Those exhaust brakes are restrictive anyway. You need to lose that thing and put a 5 incher in its place

[Cryotek]

PeterT, is the variable part of the new turbo on the turbine side(exhaust) or the compressor side?? Both have pros and cons just wonder which you went with and why?

 

[FDavid]

Seane I figured you would be on this thread the way you go through turbo's :-laf . I was about half tempted to dump that exhaust brake until Piers got me a B1 that worked with the exhaust brake. I just want another choice.

Stop by sometime, maybe we can trade some cheese coneys for a set of stacks
