I am curious as to how many of the Turbonetics drop in guys will be willing to lay down 800.00 bucks plus shipping 35 lbs to and from Cali. and have their truck down for however long to upgrade to the BB center section???. gotta tell yah, I am wayyy dissapointed in this price. All the talk of failures with the journal bearing turbos must have faded away and maybe TN doesnt feel it is necessary to take care of all the Existing Customers as was stated before.

FYI anyone, even chicks can change that center section out 12 point 8mm or5/16 1/4 drive socket. NO need for TN to do it for warranty reasons IMHO, sell me the parts without warranty on the wheels as that is the only thing you could possibly damage . Its a turbo not DIY injectors!!!!!!!!

I suddenly fell back in love with my regular old (WELFARE) turbo again today, cause my self and nobody in their right mind is going to invest 800.00 Plus frieght into a 1300.00 turbo that is working fine.

8500 approx miles on my TN with no problems yet and I love the performance of the turbo especially towing, but months of excitement for the affordable upgrade, for Existing Customers only, and then bam not gonna happen...

Poor, Poor me
Tears add flavor to your Beer :lame:

Dude, I am in the same situation and waaaay disappointed too. I am a big BWD fan and not one to complain but all the talk about TN "taking care" of the existing customers went down the crapper :supergay: I really like my TN and bought it only 2 months ago and it was told the upgrade would be next to nothing and was convinced I should get the thrust bearing unit and "simply" upgrade it when that was available. Sorry but $800 is not a simple upgrade and way to much to pay for this..

 

[ELKHUNTER]

Turbonetics, question here, If I am gonna send you my .84 turbo to be upgraded to a BB unit and all you guys do is unbolt the wastegate actuator and the compressor housing and bolt them back on to a CHRA with a 1.0 exhaust housing will you sell me another compressor housing and send my old center section including the .84 exhaust housing back to me and then I can have a spare turbo or one to sell???

That is Bull Shtttt I could build two turbos with the purchase of a wastegate actuator and a compressor housing. You might should re think what your doing, free cores for TN. Not Cool the Turbo has already been bought once, you made a profit then, dont try and make a second profit.

 

[Diezel Dawg]

WOW, This is interesting fellas, because if i remember right, Joe(CSI) the TN Turbo :nutswinger: always talked about how cheap it would be to rebuild one of these turbos. Will it be the same price if u have to change out the bearings again??? It cost the same amount to have Garrett do the same thing. And it really sux that TN told u to buy the old one and then send it back and they would hook u up. $800 doesnt sound like a hook up, sounds like they wanna make a buck or 800 of them. Makes u really wonder if it is worth all the HYPE!

 

[THEDIESELMAN]

Well I will let you know if it is worth the HYPE when I get mine on next week I hope and from what I have read they are great there are people running the TN BB with B codes.

 

[ELKHUNTER]

The BB flows the same as the the Journal, the ball bearings have other performance features that make them disireable to me...

 

[THEDIESELMAN]

The only thing I can think of is faster spool up and it should do better than the journal bearing turbo in the higher HP applications.

 

[69W900A]

If the turbo uses the same compressor setup off the journal bearing turbo the BB won't do any better in high HP applications. The spoolup is just that, the rate at which the shaft speed increases, that doesn't significantly affect peak boost/air flow. There might be a slight increase in shaft speed due to a decrease in friction in the cartridge.

 

[ELKHUNTER]

Faster spool up number one for me, they say it will handle 50 times the thrust of the Journal. The Journal TN on my truck is just as laggy as the stocker, lights up about 2000, BB is supposed to be quicker, wouldnt it be nice to start to spool hard at 1700 or so.

Let us no what you think once she is on.

Mine is pretty laggy down low too.

I will let you guys know how it is when I get it on I still need to get my highflow outlet, non-ebpv ped, and the o-rings for the turbo I wioudl install it this weekend but don't want to have to do double the work so I will just wait and do it once.

I think that the BB will support more HP than the journal because it is a better stronger design.

 

[69W900A]

The BB cartridge will support more HP, the turbo will not. If you do not increase air flow you cannot burn more fuel. If the BB uses the same compressor as the journal bearing drop-in then it will support the same HP, but with faster spool up.

 

[THEDIESELMAN]

I understand what you are saying but what I'm trying to say is lets say the journal bearing is good to 350 hp and after that you are just over spinning it, so it isn't able to support more HP just because it is a journal bearing turbo, now lets take that same turbo and make it BB and lets say it can support 450 HP just because it is able to support more of a load.

 

[69W900A]

Ok, but over speeding a turbo means the shaft speed is too high meaning the compressor wheel is spinning too fast and the BB is not going to help that. I understand that the cartridge will support more of a load, but the compressor wheel will barely support 350HP in the journal bearing version. So putting the BB version on a truck with more fuel still gets you a turbo that will support 350HP.

If you are happy with your TN then by all means continue with what you like. I'm just saying that unless you change either the hot or cold side configuration you have not changed the amount of fuel (meaning the amount of HP the turbo will support) that the turbo will clean up.

Some of us are aware you didnt enjoy your TN, but I think the point in this case is the BB is supposed to be more durable, take more abuse, last longer under extreme loads etc... not make more ponies.

Oh I see and I hope the TN turns out to be great just need to get it on the truck first and it should clean up more fuel down low becaue of the better spool up right.

That is what I have been trying to get at and that is the way I see it also.

Also what about the TN didn't you like 69W900A I would like to know.

 

[69W900A]

I didn't like the fact it didn't flow enough air for 350HP. I thought mine was a bad turbo. Since my original few posts on the subject I have acquired a couple new and used TN's and tested them with the same results as my original turbo.

This last test I put my stock turbo back on while I decided what to do. After I David shipped me my 38r and I saw what a huge difference it made I wanted to confirm whether I had a bad TN or the design had an issue. With the stock turbo I made a couple dyno pulls. Then repeated with each TN for the same result each time. Both the stocker and 38r made more HP.

The TN is much stronger than the stock turbo. ELKHUNTER, I never disagreed that a BB cartridge is more durable. The statement was made it will support more power, which is not true. The BB cartridge will simply increase spool-up and it will take more abuse unless you change turbine/compressor parts. That is all I'm saying. Performance wise the TN BB can't support more HP than a journal bearing TN if they both use the same compressor and turbine parts, that's all I'm saying. I'm not trying to bash the turbo or dissuade you form using it.

 

[THEDIESELMAN]

I wonder why the TN made less HP then the stocker that doesn't sound right at all and was it a the BB turbo.
