Blown Turbo

[rev210]

i was under the impression that heat is one of the main things that can kill the ceramic exhaust wheel in the stocker, and that being close to or on the limiter wud create more heat then usual and shorten the life of it over time????

please correct me if im wrong im still a newb

The turbos shaft speed increases with the increased boost and tubine backpressure (used to drive the turbine, instead of passing through the wastegate) leads to higher temps, given people are able to make often very similar power at 10psi as others do with 14psi it may also be that the turbo is outisde of it's efficiency range (don't know of any compressor maps for the stocker though) at 14psi meaning higher intake temps and possibly resulting in effects on tune giving a higher exhaust temp. Tune can also result in higher exhaust temps which would lower even further the boost threshold.

Bottom line is there is has been a fairly long list of people over the years who pop the turbo at around 14psi-ish boost over the years, this is the most common link to turbo failure you will find.

did it want to stall when you took your foot off the accelerator pedal after the noise started?

um no mate not at all hey engine running fine.
