Shouldn't these failures would be happening and being reported daily here, or elsewhere? I'm not saying that it's not happening, but if it is, it's impressive that people who have had this problem are keeping it so quiet...

It's obviously not an easy failure as only 1 person has reported it (to my knowledge)... and there are many tuned cars out there with 30k+ including Vishnu's shop car which has often ran more than 15psi with 0 issues and hard dyno, street time and track time.

I believe he has seen a car with a turbo failure, but I think it was a car using the proven to be compromised v2 with full catless exhaust and an intake. Probably using high torque settings and had a car that was wildly overboosting.

Thats the dilemma. You normally wouldn't total a car unless the repairs exceed about 80% of blue book value. But then again, these aren't insurance jobs in the first place. But you can't logically relate repair costs to car cost when you realize how much it would cost to buy all the parts in a car seperately as opposed to the cost of an entire car. They had various studies, and I don't remember the figures, but I would venture to say if you bought every part seperately for the 335i, it would probably be $150,000-$200,000. I'm sure some experts in the field can chime in on those figures. So the cars are too new to total, and too expensive to fix with a good conscious.

Yeah like I said, with that combo weve seen 22 + Psi.... If you hold that to redline no shit you are fucked.

Im gonna give my final ruling as a driver error. Dont replace the turbos replace the dude behind the wheel and get a boost gauge.

Obviously if your wastegates are making the sounds we heard in the video, you shouldnt push it.

The sound in that video isn't from the wastegates, but I don't believe it's abnormal. Without a real reference theres no way to tell how loud it is, but turbos whining isn't exactly strange. Especially super high RPM turbos like ours.

The chattering seems a little abnormal, which from where it seems like sound is coming would lead me to think the bar opening and closing the waste gates ticking. I definitely havent heard it in my car but it sounds like what Mr. 5 and others describe to us.

assuming they arent using any special audio recording equipment and toning in.

And probably not the recommended maps and probably on race gas... but we all did enjoy his vs. V10 M5 videos

Are we talking about the same video?

There is no abnormal chattering in that video its all injector/valve sound believe it or not.

He was pulling v10 M5s? Oh my gawd why is this even a thread?

Its definitely not normal and will be very noticeable even with your windows up. Many people with mods and turbo failures probably won't be disclosing it publicly.

also has anyone seen this? Impressive. :

AA blew their turbos by peaking 18psi for some time. What I miss in this discussion is that Alpina boosts up to 16 psi without any consequences on the turbos. Well, they use a lower compression ratio. However, this topic leaves a lot of room for speculations and we really don't know much about high boost turbo failures. We should be as objective and fair as possible here ... I am personally more on the conservative side by avoiding a possible problem in advance it occurs, so I understand the discussion very well. However, let's try to keep objective here.

Thanks,

The compression ratio of the engine won't affect turbo failure...

We have no way of telling if 11psi is too much, let alone 13psi, or 15psi... if the turbos can sustain 18psi to redline then anything below that maximum poential can be considered conservative. I used to run my stock eclipse turbo up to 19psi and it would fall to like 11psi by redline so this is all relative. What probably needs to be done is a measure of variance and oscillation, can you apply your engineering abilities and help the forum out?

Define "many", it is unlikely that there are that 'many' tuned +30k mile tuned-cars.

+1 It is of no benefit to the person with the "issue" to disclose the turbo failure.

Hotrod, post the DME printouts. I do not see the harm in presenting that information.

probably as many as there are BMS tunes in total?

very impressive for sure. It seems that the coupe we are talking about though may have been boosting over 15 for sure. no evidence though, just speculation on that

yeah my bad that is a different car in the video, it's a sedan, this is what i get for assuming and trying to post while working (Saturday? Seriously? Blue sky and everything? Ugh.) Sorry all. I'll leave lol.
