Blow Off Valves

[TurboTPI]

I know i dont have a sy/ty but i was woundering if they came with bov's? I know grand nationals didnt. All i hear is that you will destroy a turbo if you dont have a bov. Then why does my dads grand national have 120,000 miles on the stock turbo. No bov. I know that compressor surge is not good, but is it really that bad?

They do not come with BOVs. I have had my stock turbo without a BOV for 145000 miles and it has no shaft play at all. But it might have been replaced at one time by previous owners. They help, but aren't needed really that much, till you start pushing some serious PSI.
