Dang, sorry about what happened, hope everything works out. My 20g builder told me a few precautions--the potential bearing failure, bad shaft seals, etc. In addition, since my anti surge compressor was from another supplier there is the risk compressor wheel tagging the wall with the mis match. Meaning, even if the housing is advertised to accept 20g, it doesn't neccesarily mean its right for the design of the cw.

So don't take my post as saying its faulty parts.. But that being said I am not ruling it out either. I am sending it back to the vendor to verify and deal with what ever there assessment is.. Either My error or theirs..

did I start a thread bashing the vendor saying they sell crappy parts? No.. I just was posting my experience on here in case anyone else was attempting this or had a similar experience.

Thanks for your opinion and in the info.. I find posts like this beneficial.

I think you are missing the point. you are wasting your time sending parts back. they will do nothing for you. when you buy parts of a turbo it is your responsibility to use them correctly. even if you had the turbo assemmbled at a turbo shop they would not be able to warrant someone elses work.

you say you did everything correctly yet you want to send them a damaged wheel to see if they will be able to determine wether or not compressor wheel was balanced.

I.E. you cant determine if a wheel was balanced once its damaged.

got your point..

I made the determination that it could be the wheel(understood if its out of balance they can't tell now) and or the housing may have been an issue.. ...

Just looking for there opinion and input..

Thought I would update the thread... So i can get flamed some more...

So the vendor.. Turbo Lab of America called me and they said it appeared that the Vband was not TQ'd down enough so ever so slightly the housing cocked. They said it was odd as well. Few other unknowns... So big

to Turbo Lab of America they have been really awesome to deal with. Going to have them rebuild and replace the damanged items.

So didn't have to do with balancing.... Happy they were able to figure out the main issue...

Should be a few weeks before I get it back due to backorder of parts.. Thanks for all the info in the thread..

Wait what?
Since when does somthing spinning @over 100,000Rpm not need to be balanced?
I have a turbo Rebuilding shop here they do my turbos for me and they been doing it for a longggg time and would laugh at that statement.
Its balanced as a assembly,
Its also not a RE Balancing, since its new its a Balance, since the Intake side would NOT be balance to the shaft/turbine of the Hot side.

hand tight + 1/4 turn is an old grandpa rule for oil filters. I've never heard of not balancing a complete rotating assembly. Garrett and Precision always have assemblies always have material removed from the nut to balance.

The manufacturer needs to have the cartridge to verify that. One can't just know how the turbine shaft and wheel is before they ship any wheel. This is why most distributors/manufacturers of these wheels will not sell them separately without at least the owner's cartridge in hand first to balance the cartridge before setting the compressor housing on it.
