Ball Bearing Turbos.

[Diesel Freak]

I am looking for a ball bearing turbo.



Specificly to replace a HX40. I would really love one that had a Garrett T66 compressor and compressor housing, and had a turbine and turbine housing that flowed like a Holset HX40/16.



Spool up should be at least as good if not better than a PDR40.



I know someone out there has one that could bolt uo to a Cummins Manifold without a spacer.





Come on now spill the beans!



I need something that can handle being fed by a Thumper!

Have you looked at what the Garrett is doing with the Fords?

The floating on oil in a bushing method seems like it would produce less friction also

i believe it is the other way around. the oil makes a fluid wedge between the shaft floating it between the bushings, that causes restance [the higher the oil press. in the bushing, the more restance] a BB carterage will spin very easly with low restance. take a look at at rollerblade wheel or skateboard wheel, spin one of them up by hand and that will spin a long time, now, if you had a friction bearing with oil floating it, it wouldn't spin near as easy...



i still want to see that twin compressor/single turbine idea go into production...



scan out of SCC magazine of the idea...

Yes, I even got to fondle one at the PDR Dyno Day.







Just wish they had one to bolt onto the Cummins!

We got a VERY low number of custom ones from them that I REALLY wanted to try out. Still might get to.



I'll let you know how it works.

Garrett is actually in the process of making a ball bearing design for the cummins. They are claiming they will be available middle of next year or sooner. We all know how that goes though...

From my understanding they wanted to make a "universal" turbo that would suit all 3 diesels, don't know if that is still the plan or not.



One of the Garrett engineers was registered on thedieselstop.com and got a good working relation with my boss.

I have rode in a Dodge Ram 24 valve Cummins equipped with a ball bearing turbo.

Sounds crazy, and spools very fast.

That would be the next toy on my list if they came out with one!!!

DF, I saw a T-88 on a Mustang today that I'm welding a set of headers for... . I like it and it moves like 1400-1500 CFM and is not high in price!

Did you get a chance to see the A/R of the housing? Did the guy know what turbine was in it?



Turbonetics has six variations of the exhaust side, and this is not counting turbine trims.

Diesel Freak, ya should have looked under Nascar's hood at Dynomania... . we've been testing a ball bearing turbo on his 1st gen truck for Garrett for awhile now. So far mileage is up, egt's are down, throttle response is better, but we have another version coming, so we'll wait before posting all the details.

This is what Piers is talking about.

Cliff, I'm no turbo guy by any means but the intake side said . 75 A/R, the exhaust housing housing is a little small than my 3B as best I could tell but the impellers are bigger much like a B-2, he's going to run it for a while then switch over to a 100mm or a 106..... Oo.

Ceramic bearings

Just a thought, has anyone try to search ceramic bearings from manufactures like Timken, to get measurements of their bearing and open

e. g. HX-40 to see if it can be machined to accept ceramic bearings... ... . hmm, maybe I should first finish my Cummins before a new project...

Piers, I saw it, and I also picked Marks brain about it. I did not want to post about it because I was under the impression that it was an experimental piece.

Ball Bearing Turbo

When Piers offers a ball bearing turbo, I'm buying!Oo. Oo. Oo.

 

[TxDieselKid]

Just think about it on a twin set up!

Guys,

This turbo rocks. I have been running it for 2 months now and don't want to take it off except for maybe the new bigger one coming. I've been beating on this turbo (50psi daily) and working with Garrett by giving them feed back and advise on changes for our trucks. Their head honcho tells me it will handle 50psi daily so it gets it if it likes it or not.



So far so good. It has a . 89AR housing and flows good air. Pulls almost as good as our HX40 on the top end. It flows better on the bottom and mid and flows more than our HX35 at all levels (bottom/mid/top end).

It is a pleasure to drive as it spools quick and smoke is way down. Very clean runner as it responds like right now.



We'll keep you guys posted on our findings in the future.

Mark or Piers,



Is the gentleman's name Brian that your working with?
