Turbo without Blow Off Valve

[cantfindausername]

Hi all, I know that with a Turbo you should run a Blow Off Valve to prevent compressor stall, but does it really do any harm to Turbo to run without one? I've heard various stories that back up claims, but figured this is the place for real knowledge.

Thanks in advance,
Ant
