30K is one big loss, although I'm sure many parts can still be saved. So maybe you can minimize the loss- you've said this was your second build and it seems like you have bad luck.
From what it sounds like it's really all about risk of building. There are many people who build engines for that purpose- high numbers. Yours were good and there were issues. Hopefully you keep on going, and find out exactly why the turbo failed.

Precision had no explanation of why the turbo failed other than defect, mass produced parts I guess are bound to have issues, we will see what happens this time around with this kit and build. Hopefully there will be good news and not more issues with this combination.
Hey Shadi(gixx76), I replied to your email. I read through this thread and this doesn't paint R/T(or myself) in the greatest of light...
As we have been in contact this whole time. If you truly want to find the info you need from a public forum such as this its only fair that you mention all the facts, such as you had the car retuned by a different tuner and that a few weeks ago(before the retune) you had an oil analysis done it and it showed zero evidence of any bearing wear. If you did mention this I apologize I missed it, if not I can give some more useful info below...
Now I am not pointing fingers at the other tuner, but he did find that the tune was running lean and he was having some knocking on the dyno which you never mentioned to me(which is weird because you emailed me with every other issue). At that point I could have looked at the logs(which I received later after the motor issue) that the other tuner had and would have been able to point out the fact that your MAF voltage was down .025-.3 of a volt lower the what it was reading at the same boost level when I tuned it a few months before that. With the MAF reading a lower value it was targeting a lower BFS and seeming running more timing and giving less fuel due to the lower voltages. Instead of being able to diag as this a MAF sensor that was now skewed (from the blown turbo spewing oil all over it at that track day and for probably several 100 miles as well) the tuner just added a considerable amount of fuel in the fuel comp table(which is the last table the ecu looks at for fuel compensation), which in my opinion should have thrown a red flag and would have triggered myself to look at other possible issues. So when I looked at other logs I saw a log where right after full throttle the MAF voltage just drops out and then comes back to where it should be and this is the tell tale sign that a MAF sensor has gone bad and I would have either stopped tuning or replaced the MAF.
So in conclusion after getting all the info of the blown turbo spewing oil into the intake which you haven't been able to get all of it out and in itself can cause pre ignition, and the skewed MAF voltages which were clearly causing the car to run lean, I feel that you possibly had some hard knock events which caused some bearing damage which is giving you the noise you currently hear.
And Shadi if this comes off as my being a little annoyed its cause i am and maybe because its because I have had a really bad week..but i feel I have always offered you great customer support and always been there when you had any technical questions and have spent dozens of hours of customer service. Like I said I am more the willing to work with you and figure things out but I don't necessarily agree with some of you posts when you have issues.

number 1 reason why uprev is unsafe on a boosted car!
you can argue the pros of it all day, but in the end you have absolutely zero saftey features to protect your motor.
Does sound like reasonable explanation to this entire story, so hopefully amicable resolutions will be found

Sorry Sasha, MI was not making the same power if I understood correctly and also using a different turbo and kit.
Until the kit you sold me works for my intended application in combination with a perfectly built motor, then there is an issue with the Kit/ set up for road racing at this power level. Those are the facts as they are. Until that changes will have to stick with that. Sure does perform great on the dyno for a few runs though
If and when this kit/set up and motor show me it can handle what I throw at it with certainty, only then will I give anymore praise to something that has failed on multiple levels. Not your fault, you are a great welder, just so its clear. Thanks for your comments though. Maybe in the future when one of your customers tells you they are going with the same builder as you suggested legitimately as THE tuner for your kit, you should think twice and tell them maybe they should rethink that.
I am getting tired of you and R/T going opposite directions and am near close to just forgetting both at this point, you say bad builder they say **** turbo with a kit that flows good and has good welds,, who to believe, I guess both at this point. I hope for not since these are the two businesses I chose to go with but if it turns out that it is so then I guess I was wrong on all fronts and will have to go elsewhere. No fault but my own in the end really.

He IS using the same oiling system, same turbo (just a larger compressor wheel) and making more power than you. So for sure the two are very much comparable.
Once again, it is not my business where my customers go to get the install done, built engines done, and the tuning done. You had asked me on advice on all of those, and I had provided it (as stated in your other thread). In the end it is up to the customer to spend the time and do the research before going ahead and investing on something like an engine build. When I did give you advice on my own product as far as upgrading to the .96 a/r turbine, you ignored it. This is straight from an email I sent you:
On Thu, Aug 16, 2012 at 9:32 AM, SASA SUBASIC <sasasubasic@hotmail.com> wrote:
I can tell you that it is necessary (the .96 a/r turbine housing) if you want an efficient 550+whp build.....
I am not trying to sell you something you don't need. This recommendation stems from all the R&D done on the kit. The customer that made 580whp was already maxing out the flow capability of the .81 a/r housing, and to go past 600whp he would have had to upgrade to the .96 a/r housing.
This is something I told you as the kit manufacturer...and you did not follow though, because I did not want to buy your old turbine? Come on, tell the entire story....and then you want me to tell you not to go to shop X or Y for other work?
Also, as noted a few times already... at no point did I say that R/T is a bad engine builder, as your quote states:
I do not have any direct experience with them on this end, so it would not be something for me to comment on. You are once again posting false information.
The turbo failed..yes, and even Precision doesn't know why. It is unfortunate, and I did say to clean everything on the intake side, that would include the MAF sensor. Now that Vince explained the retune event, it is starting to make a lot more sense...and once again it goes back to the very first thing I told you. GO TO VINCE AND LET HIM TUNE YOUR CAR. He knows what he is doing.
gixx76, you seem to believe that this platform can never fulfill your requirements. If so why don't you sell what you have and pick something else to build. Doesn't seem to make sense to persist based on your experiences.

I've never understood how guys can spend 5 figures on a FI build and then balk at the idea of paying $3K for a proper EMS to help protect their investment.
Not even iI didn't even spend that on a aem infinity-10 plus universal harness although I got a deal, the haltech dosnt cost that either. Only pro rfi honestly.QUOTE=RudeG_v2.0;10181871]

This isn't an EMS issue... (UpRev works when you know what you're doing) this is a, this owner it's an idiot who omits info when he knows he's F@#ked up and then blames everyone else from builder to manufacture for his stupidity.
In every thread he's started about his build so far, all he's done is point fingers at everyone else while playing the victim and looking for sympathy.
So far, BP kit sucks, Precision Turbos are junk, Sasha has the worst customer service, RT can't build an engine and Vince can't tune for ****. Basically this sums up what gixx76 has b!thed about in all his threads recently.
Who the F@#k takes their car to a builder who actually knows how to tune and then decides to let someone else (or shop) F@#k with the tune. Only this idiot does. Yes, a bad tune can royally F@#k up everything else.
The problem with this whole build is you gixx76.
and for the love of God, stop opening new threads about the same BS every time you get called out for your BS. How many times do you plan on contradicting yourself and half a$$ apologizing for your own mistakes after tarnishing shops and peoples reputation!?

LMFAO, Thanks again to those wit constructive comments, Thanks Vince for taking the time to go through everything in our phone conversation.
Sasha Anis is a tuner that is well respected and in know way should anyone be making statements of his tuning inadequacy, that was not and is not the issue, the issue is simply due to a chain of events that caused this end result.
Turbo failure -causing pump failure -causing motor failure in the end. So it all starts with the defective turbo, I can't comment on if PTE is **** or not because I have nothing personally to compare to other than the crap one I got through Boosted Performance...Vince on the other hand is the one that has made it CRYSTAL CLEAR in his opinion that PTE is as good as garbage if not worse.
I am not to blame, Sasha Anis (OnpointDyno) is not to blame nor is the Vince to blame, just shitty events that equal the current situation.
Not much more to say to any of the other tools in the shed here.
Will be rolling again soon and will see if all work or if we will just scrap the crap and go back to something that works for what i will be using it for.
