[BP single kit] Compturbo died @ 6k miles; looking at replacements

madwi

I didnt realize you had reached out to them at all.


Happy note new turbo is scheduled for delivery on Monday morning. Hoping I can cram everything together and get the car rolling before the Z get together on the 17th.

Yes, a brand new turbo, and is covered under warranty. COMP figures something got into the original turbo from or through the air filter. There was no defect found on any of the rotating assembly, anywhere.

Was there foreign object damage on the inlet impeller? Any marks or scratches on the pressure side of the blades? No marks, go to the next question.

Is there is rub marks on the edges of the blading. If so, the bearings failed.

Well, simmilar assumptions were made in the past when a customer had an issue where the compressor wheel contacted the compressor cover. Turned out that at the time of install customer installed the compressor cove, and tightened the bolts, without ensuring that the cover is square on the back plate.

So everything would suggest that it was a bearing failure, and only after a couple of hundred miles. Turned out to be an install error...that was also covered under warranty. Not sure that other turbo manufacturers would do that. I know for a fact that PTE wouldn't.

COMP makes a phenomenal turbo, which is extremely reliable, backs it up with customer service, and always stands by their product.

I used to work for Elliott TurboMachinery, rebuilding large turbo's. Without looks at the turbo up close. Can't really do a root cause analysis. But just by going on the info at hand. That would lead me to the bearings.

That is exactly what happened. Comp can stuff the "it ate something" BS. The inside of the filter and turbo where squeaky clean and you could clearly see the fins on the intake side had touched the housing. There was also a slight amount of play on both sides.

It was most definitely was a bearing failure. Someone somewhere is trying to hide what happened.

Assumptions without facts is always a bad idea.

Like I said before, there was an incident where the compressor cover was removed from the turbo at time of install, and not installed back properly (square). The damage was identical to this, and forum warriors were all over it...*Sh!t turbo, "turbo needs oil brooo"...bla, bla...BLA!

No different than 3 customers having overboost issues...forum experts jump right on that too, and say poor design of kit, this that and a bunch of other BS. Only to find out that the installer mixed up the vacuum lines.

Always enjoy opinions, base on 3% of knowledge about the actual situation. Been doing this for a long time, seen it all.

As for "play", every turbo has "play", especially a JB turbo. If it didn't, it would explode the first time it gets up to the 1,400 deg F operating mark under full load.

The fact is nothing went through this turbo. You and comp are assuming that happened.

And yes. Turbos need oil. Another thing they need is coolant. The first one is why your kit didn't make my short list. The second is some kind of bad joke

And how many of those janky air cooled turbos did you have drop shipped without changing your product description? I'm sure BettyZ wasn't the only person to open the box and go

"wtf is this? I didn't buy this"

"they cool the hot bearing housing with hot air and it's not even hooked to the oiling system to help cool it off"

No wonder the warranty is crap.

Sasha I know eventually these turbo were going to come back to haunt you.

I mentioned many types of higher quality turbos like the borg wargner efr9180, garett g35-950. The oil less turbo method limits the customer's choices.

I'm not sure how it works in Canada, but in all 50 States, offering a customer a product, and then delivering something significantly different, not only voids the contract but is also illegal. The technical term would be "fraud."

May not apply in my case as I learned this before delivery and accepted the delivery. But for those that had no idea, and thought they were getting a water-cooled turbo, there may be a cause of action there.

Are they sending a new one? I'm not sure what this means. I received my old one, broken down into parts but nothing new.

I was referring to the turbo that I bought through Elmo370z.

"That's a nice turbo, it'd be a shame if we sent it back to you in seven ziplocs."

I'm embarrassed for you.

This is the hot side bearing. Or what is left of it. Did something get sucked into the hot side bearing? Is comp trying to say it ate something with no damage to the intake fins and it took out the HOT side bearing? That excuse does not match the damage to the returned bags of parts.

When BettyZ gets his bag of parts back from comp I guarantee that bearing looks the same or worse.
