Never heard of compressor surge have you, turbos dont like spinning up to 80,000 rpms with 7-11psi of boost, then all of a sudden you lift throttle, throttle plate closes, 7-11psi (or whatever your boosting) smacks into a shut door (throttle plate) and bounces off and has no where to go becasue someone eitehr adjusted teh BOV so tightly becasue it sounds really cool or just failed to install one in the first place, that it can only go one way and that way is in reverse back to the compression which by the way is still spinning asshole on fire fast and is then force to try and spin in reverse in a heart beat which in turn puts stupid force on the trust bearing assembly and kills yoru turbo rather quickly. I've seen alot of newbies to turbo'ed engines do this more than enough times. So yea you can kill a turbo real quick this way.
BTW im refffering to after market true type Blow-Off-Valves and not the factory type Nissan CBV Compressor-Bypass-Valves.
