hmmm, well if you want it plumbed back.... get a bov with a circular strait flat outlet... (not a bell mouth or trumpet). This way you can get a hose made up (similar to a radiator hose) to go from the outlet of the bov back to a inlet flanges on your intake pipe between your air filter and turbo.
here is my ghetto diagram

paint FTW, good explanation though.
Run no blow off valve for the best sound and completely legal!
how does it have the best sound??? and running a plumb back BOV is completely legal. and having one does prevent damage to the turbo, because every time u take ur foot off the gass, the air gets forced back onto the compressor wheels, which creates more stress, and some lag, as the air is forcing against the spin of the compressor wheels.
so BOV does have some fuctionality, instead of just sounding good.

IMO it's the best sound. I like the chattery sound. And that's not a proof of damage, that's called a theory. Here's another one. Bearings and compressor blades are quite strong. Intake charge air might have a mass of let's say, 100grams. Clearly you are completely correct in saying that there will be "more stress and some lag", but i'm looking for some evidence which says that this stress is more than completely negligible.

mmm, running no bov what so ever, physically doesnt sound too bad but seriously does have long term repircussions. Dont really need to show evidence, just go ask any manufacture why then run a bov type device standard? because they are made to last. i mean i dont think most if not all leading car manufactures run a bov just for the hell of it? or because it sounds good ahah. feel free to rebut

I believe that manufacturers run a blow off valve (plumbed back) to avoid noise pollution, and in mass air flow systems, avoid the rich backfire on gearchange/throttle release.
If there was any actual physical evidence derived from a real test, every blow off valve manufacturer on the planet would be pimping it till their last breath. Though, i'll admit, I don't keep up to date, so there very well could be a test floating around somewhere, which is why I asked for 'evidence'.

yeah thats cool on the sound, everyone has there own opinion on it.
can't really provide any evidence on damage, i can only base this on info i have read, and like sexc86 said, that manufacturors(sp?) fit these on stock cars. but in theory, it does seem completely logical that not having a BOV will cause more damage than having one fitted

OK guys I got the theory down!!
Its very easy to understand but what make/model is eazy to make legal buy running a hose back through the lop..
Just like my PC water kit

u want a plumb back BOV, try GFB or turbosmart, there pretty good brands

Hows this one?

i'd go the second one, as the first one looks like an atmospheric one.

Dont get a BOV. If BOV are so good. Why dont race cars use them??
Ever watch the Bathurst 1000 back in the early 90's?
Those sierras ran 40 psi racing and 60 for quilifying. Dont hear them going PSSSSHT when they shift

I thought they would be setup with flat shift, so their throttle bodys would be alwayes open (even gear changes, ie dont have to remove foot from gas peddal) therefor they would never loose boost pressure inbetween gears nor need a way to vent it?... please correct me if i am wrong
