Ball bearing SRM K24

[Bond]

Anyone with experience with the ball bearing RS6 hybrid? Unable to find any picture or info online thats why. New build happening and came across this option on SRM website. thanks for sharing

[Corradovolksb]

I don't think srm offers a ball bearing option yet but I know something is in the works.

[JaredB5s4]

Yea they do now I saw on there website.

Yup it's a $500 adder for ball bearing CHRA. Wonder what bearing cartridge they went with?

[julex]

made of finest chinesium no doubt :)

[LightningLou]

We need more ball bearing options for our platforms. It's ashame that Tial and GT is really the only option for ball bearing turbos up until now... So many ball bearing options for the evo and sti guys it's not even funny. This is a nice step in the right direction

No one is going to offer good stuff when the majority of S4 owners are looking for the cheapest Chinese junk turbos they can find. If they can save $5 over the other cheaper China brand K04 they go for that.

Oh don't forget that most will also tell you that anything bigger then K04 or RS6 is too big and has too much lag...

[zillarob]

Anything bigger than k04 or rs6 is too big and has too much lag

No joke!!! Not to mention most of the time you see a B5 for sale everyone is instantly like OVERPRICED!!!!!! I could list my 100k mile Casablance stage 3 avant today for $12k (never would sell it that cheap) and I'd still get some tool in there saying it's overpriced.

crying laughing right now ahhhhhahahahahahahahahaha

This is interesting.... I'm a ways out from doing anything more to my car, but I had decided that I don't want to run 30+ psi on anything journal bearing.

I was down to 770's or BB 6262. This opens up another option....

can I ask, since you deal with diesels, I do as well, on a much smaller scale and size, why would you not want to run anything over 30psi on a journal bearing? just curious, looking for some good points of view and info on the matter.

[DieselElectric]

Honestly just personal preference. As long as you aren't pushing the turbo outside of it's efficiency range, it's not going to be an issue.

That said, all of these big twin setups (k24, 770, ect.) Are using small turbos, so going to a ball bearing setup makes sense if you intend to really push things.

This is coming from someone who is currently running up to 26psi on f21's daily driven.

[kevinpower]

Hello can you drive 600+whp on this srm k24 turbos ?

[axnjaksn]

gotcha, f21's at 26 psi is nice, e85?? meth?? 93 octane??

[DieselElectric]

93+ 2 d07 nozzles and 100% methanol. 23-24* advance up top.

BB is more robust for dealing with high axial loads versus a JB.

[Bond]

how about anyone with experience with the newer spec k24, the compressor looks to have 9 blade on their website

[themadscientist]

JFC... Yeah lol good luck with that. I have a nice sample here of a very low mileage K24 with an absolutely destroyed thrust bearing and it was pulling teeth just to get a new CHRA.

[Bond]

that sucked, thanks for sharing

[qwnzr]

bump, has anybody run theses yet? noticed the price was bumped up to 700$

[Peter1.8t]

Last time I talked to Sean he was having reliability issues with them so he wasn't selling them just yet. Maybe he figured out a way to make them more reliable.

[Mocke]

He has realibility issues with all his turbos, It hasn`t stopped hom Before :) China crap.

[FlyboyS4]

Baseless statement.

[S4James]

I believe the CHRA's are from taiwan, there are only two plants producing them, and both have excellent reputations with turbo builders.

This is information from an actual turbo builder/rebuilder with a couple decades of experience and a huge reputation in the field, and not some internet troll with an axe to grind.

[Peter1.8t]

That maybe true. I don't run any of his turbos nor I recommend them to anyone. I like BW products personally.

With that being said; would his turbos still have reliability issues if you got a cut of the revenue for the help you provided him with?

[Drehmoment]

You dont need "ball bearings" to make power........TTE genuine BW not chineseium equipped S4/RS4's make up to a 1000 plus crank in Europe with real world data to back it up....not just dyno queen sheets.

If you have a existing not totally beat up set of Ko4's the upgrades are not exorbitant expensive even on the 780/850/950 levels but the problem is most potential users do not realize that quality is never cheap and cheap is rarely quality. The fit and finish between the TTE's and various chicom menu offerings is dramatic.

[FlyboyS4]

I did not see anyone making that assertion, or were you pointing out the obvious?

What genuine BW compressor wheels are the TTE's equipped with?

Though if you're asking Frankenturbo versus TTE 550 pricing, you've got to drill down into what performance the over 100% higher cost of the TTE550 is delivering to you.

[DieselElectric]

Why did you put ball bearings into quotation marks?

It is safe to say that you do some mild R&D for Franks, I dont want to accuse you of shilling but IMO you are not far away from it.The million dollar question is how much of your set of TTE550's machining will be copied over to the Franks thanks to you ?

However I do like your website with the research you continue doing

[FlyboyS4]

It is safe to say that you do some mild R&D for Franks, I dont want to accuse you of shilling but IMO you are not far away from it.

The only piece of FrankenTurbo hardware I've ever helped in development of was flow testing a y-pipe prototype that never went past the development stage.

I'd like to do R&D for FrankenTurbo, or SRM, or TTE, or <fill in the blank with another Audi aftermarket product vendor> as you are imagining, but you grossly overestimate my involvement. I'm quite willing to help vendors in their product development efforts for this platform, I love seeing new options for the B5 S4.

At the end of the day though my strongest endorsement is made by what I put on my car. I have specific goals in mind for my S4 and the parts I equip it with are what I feel are the best to reach those goals. Nobody pays me to say they have a nice product, that would be pretty cool if they were willing to do so though.

The million dollar question is how much of your set of TTE550's machining will be copied over to the Franks thanks to you ?

Sorry to disappoint, the answer is nowhere near worth a million.

But to make sure I understand the question, you think I bought a used set of K04's and had them shipped to TTE, was told the turbine housings couldn't be used for a rebuild so I bought a good set of turbine housings from TTE, had them build the 550's and then paid for those, then tested them on my car, then before I sold them to the guy in the classifieds I shipped them off to FrankenTurbo so they could disassemble and reverse engineer them, then FrankenTurbo reassembled them, sent them back to me, so I could then sell them to another B5 S4 owner? That's what you think I did? You need to write mystery novels.

You didn't answer my question, 'what genuine BW compressor wheels are the TTE's equipped with?

There is no Point discussing quality any longer.
US market is so poisoned with Crap quality, that younger generations does not even understand the difference.
Let them have their Chinesium.

Absolutly. Seen it fail first hand on several setups. Never claimed any Revenue from him at all btw.
