my buddies T-25 self destructed last night. The turbo made the ususal hiss then a cool sounding supercharger wind up noise during spool up.

Turned out the vains was scraping against the housing, resulting in chipped/bent/glued against one another turbo vains.

Now I felt bad making fun of the T-25..

I think it was a combination of boost spike (1.78 bar), and heavy compressor surge that killed the turbo. Remember kids, when the turbo spins toward the speed of sound, it shatters the vains.

Any ideas of turbo/ intercooler upgrade?
