Heya Joe,
Actually, there isn't anything different that we do when we balance a BB unit. They are all group balanced then put on the VSR for final balancing.
The problem is trying to get parts out. Nobody is allowed to get BB parts unless authorized by us. Finding people who are authorized to do so is a different matter..

Thanks for the reply Dave, I was surprised to hear of the "special balancing process" It's nice to dispell the rumors from actual fact

Hi Otto,
Actually, we run the BB only on the compressor side and bronze bushing on the turbine side.
The reasoning behind that is, there are some minute vibrations within the shaft that occur during normal use. The bronze bushing basically asborbs any minor vibration within the unit.
The dual ball bearing turbos do not offer this sort of dampening.
Hope this helps!

JM,
To clarify my statement earlier, the VSR balancer as I understand it, is the key. It enables Turbonetics to balance the complete assembly as a unit vs individual components balanced and then assembled. Turbonetics does VSR balancing on all it's tuirbos, I don't know of anyone in the country that has the equipment to do that. The BB units require closer tolerances after final assembly, that is why I only use Turbonetics. Well, one of the reasons, Kathy is the other.

JM,
The "special balancing process" is just that. That would be the VSR process. No 'rumors were dispelled, only further desribed for you. Sorry if I didn't make it clear in my first post. Hope you understand now. Thanks for your interest as I always enjoy being able to pass along factual information, to dispell the many "rumors" that tend to circulate.
Hope you and your family have a happy and healthy Christmas and New Year.
If that's the way you see it Jack, good for you. The original intent of your message was to knock John because someone other than yourself was given praise for being a great Buick vendor, now we can't have that going on cause there's only one Buick god...

Sorry Joe, if thats the way you see it, but I knocked no one here, only interjected some facts pertaining to BB turbos. Thats all, you are the one that has needled and twisted this here. No need to get mad and make ngative responses. I have simply stated some facts. Maybe if you could let go of whatever it is you hold against me, you woudn't have to follow me around the web. Just think how enjoyable life would be without having to worry about what and where I may share something, or what someone may say positive about me. This really is getting old, but, I see no need to share here, if you need to say something to me, you know my number and email address.
I'll say it again, Happy Holidays to you and your family, maybe we can start the New Year off better than we ended it. Life is too short to play these game.
sincerely,

OK, I'm going to start the New Year off right. I'm going to stop following you around the net. Hopefully I can sleep better tonight, these long sleepless nights wondering where you are posting mis-information is really taking its toll on me.
Thanks for the kind Holiday wishes, same to you. Have a safe, fast New Year

On a positive note
Well if we took a poll here about Jack Cotton,The Positive votes would WAY out weigh the negative ones.As far as Jack Cotton,He as a great guy,very helpful.My car is down for wastegate downpipe changes.I went to his shop saturday to give him a deposit for my parts and he gave me the parts and told me to pay him when i get the loot, And we are not talking chump change but a considerable amount,Obviously he trusts me very much.But never will i have anything negative to say about him.(hopefully i didnt say anything i shoudnt have)
Now maybe after that i can get a REAL GOOD deal on that T72 ball bearing turbo Jack

Hi Guys,
Kendall said most of it already, but I wanted to put my two cents in
Basically, the purpose of our ceramic ball bearing turbo was not to decrease spool up time in anyway. It was originally created to increase durability at higher boost levels.
But one of the side effects ( which happens to be a desired one ) is quicker spool up. Since you cannot feel the durability ( well maybe in the pocketbook) most people describe the spool up instead.
BTW, our bearings are a ceramic ball bearing not a roller as previously described.
Any other questions, let me know.
Yo Dave! When're you gonna hook me up with that Racegate?
I know "ceramic ball bearings" is mentioned about fifty times on your web site but are you really using ball bearings? As in spherical? Maybe I'm on drugs but I remember seeing a T'netics rep with a cutaway center section at the Import Battle at Palmdale last year (ack! I've just admitted attending a ricer race!) and I thought it had rollers (i.e., cylindrical bearings). I also remember discussion of it on the list a long time ago and I dug up some posts regarding the bearing varieties that've been saved on Chad Schwartz' site:

It doesn't matter a durn but now I'm curious! Not to mention wired after getting off the casino cruise at midnight...

Heya Kendall,
Your racegate is in the mail, yeah that's it.
I asked some of the other people here if we ever had a roller style bearing, but everyone gave me the same answer - no.
I don't know where they got the information on that page. Matter of fact, I have a Ceramic BB on my desk from stock, and it has ball bearings.
Hope this helps!

Joe,
It offends me that you would say these things that you say now about Jack Cotton. Obviously, you don’t see the same man that I do. What’s more, why would you choose this to be your formal to express them, are you not a man and can’t do it to Jacks face? In my mind, this makes you a child!!!! No one is telling you that you have to agree with his opinion or even like Jack, but be a man and have respect for one who even thou it may be a different opinion still has information to share. I was taking to Bill Anderson about this point one day and he said “Of course Jack and I dont see eye to eye on every issue, we are both in the same business and have different methods of doing things. He takes a lil dig at me every now and then and I take one at him, its mostly in fun, he helps me out when I need parts and I help him out when he needs something as well.” I mean how beneficial would it be on this site if everyone had the same option.
As for Jacks character, this is the most offensive thing that you have said. Jack will be the first one to say that he is not perfect.

Jason, Jack and I dont' see eye to eye, that's no secret, there are many others like me, there are many others like you. I do not care to debate "who likes jack and who doesn't" I really don't care...
Its also no secret that if ...ah never mind. I'm not commenting on this any more, before I really stir up the pot.

David has also helped me out on a 76BB with an .81 housing and a Q trim. I was running a 68-1 Garrett with a .81 housing and a P trim. The best times with the 68 were 1.48 sixty with a 10.80 @ 23# boost(126mph). My first run at 18# boost got me a 1.57sixty and a 10.62. The second run which turned out to be my last run (track was packed) was at 22#boost and that resulted in a 1.42 sixty with a 10.28(129mph)! If I had the skinnies on the front and a little more boost,I could be in the nines. I was a little nervous going to a 76 because of the spool up issues but that has not been the case. (I have been running an Art Carr 9" with a 3800 stall)
Good Luck,
Jeff

Then we all scratch our heads and wonder why we have a very little vendor participation. What does this have to due with the thread if you like or do not like someone? who cares? I think Jack is a great guy and maybe some people don't agree with how he does it, what he charges or what color his car his. Who cares, his car is running 9's all day and very little parts break he knows something in my book. Happy holidays to all
People, People... I think Joe and Jack were joking around. I personally know both of them (and yes, I live wayy out here in Hawaii now), and they are both stand up guys. Please, Joe and Jack, let people know it was a joke. I really can't imagine anyone NOT liking Jack (as my ambition in life after I retire from the Navy is to open a TR vendor business modeled after Jack). This thread somehow got way off topic. I WOULD like to hear if there are ANY ball bearing turbo owners that could HONESTLY say their turbo wasn't worth the extra money. INSTANT spoolup from a T-72 IS worth EVERY cent (at least in my book).
