dang, glad you caught that!

i will say i've never even heard of it happening (I've been around DSM's for a few years). sounds like maybe they just didn't tighten it, i don't see how else it could have happened.

it sounds like a rookie mistake, but then again it's definitely something that could happen to the best of them. i am interested to hear if they clear it up for you though, if they're good they'll own right up.

was there any damage to anything?

 

Make sure the BOV is working right. I've ran into this before. The BOV doesnt open and puts force on the compressor wheel which in return spins the nut off. I've seem cars suck the nut through the intake and ruin motors. Just be careful!

 

Poor QC at the company that you bought that from.
Kinda makes you wonder how (if) they "spin balanced" the CHRA

Kinda hard for the nut to make it through the IC, one would think.

 

The only turbos I have seen with a documented history of the nut repeatedly backing off, and ending in the turbo eating itself, were the T51R/T04Z series from HKS. (bullet-nut)

Is the company a vendor here?

 

yeah that is kinda scary, ima go check my turbo when i get home to make sure its not loose, judging from the topic starters location i think i may have a turbo from the same people, if they went local that is.

 

Here's an update.

The nut loosening allowed the turbine wheel to back up and make contact with the turbine housing. Ouch.

Turbo is on its way back to manufacturer for inspection. They of course asked "are you sure it wasn't oil starvation" but they'll see when they look at the bearing that there will be no bearing damage due to starvation I'm sure.

I'm not thinking that the bearing freezing would cause the nut to back off anyway. I'm almost positive its a QC problem but we'll see what they say. In the meantime, no car for my buddy to drive to work.

 

Should ask for some extra consideration (BB CHRA upgrade ) for all this hassle.

 

Well, THREE WEEKS later and its time for an update!

My friend just got his replacement turbo from the manufacturer. They say there was foreign object damage to the turbine wheel.

What the hell would come loose inside the engine, get through the combustion chamber without damaging the valves, pistons etc then trash the turbine wheel? Total BS we think. It sure looked to us like the turbine wheel was damaged from contacting the housing. I also don't think FOD would have caused the nut on the comp. wheel to back off either.

A decent company would have sent out a turbo the next day too, not wait 3 damn weeks. He didn't have to pay for the replacement but now he "used up" his "no-hassle" waranty.

 

So why not just say who the company was? That way we all know and we don't end up with the same crap happening to us?

Yeah riiiigghtt! FOD from the turbine housing maybe, hehe.

From the "archives"...

quote >>I recently bought my latest turbo from bullseyepower.com. Check them out. There 50 trim is like $650. I went to them because they offer a bad ass warranty. A no hassle warranty for $70<<

Also...

I'll say it again for the deaf... pay attention.
Forced Performance, accept no substitute.

 

Ding ding ding. We have a winner. Turbonetics it was. No offer from the dealer to give him a turbo off the shelf so he could get his car going either.

They did cover it under the warantee but of course its a one time deal even if its a QC issue which we believe this was.

My next turbo is definitely coming from FP.
