dsm bov suck in air at idle, cover the compressor and you will see, you can even look in the end and see that its slightly open.

Re:Bosch BOV
Thats because they are a "Bosch" style.They are not BOV's,they are bypass valves.They are meant to be vented back into the air intake down stream so yes if it is vented into the atmosphere it is leaking boost out.

Re:Bosch BOV
They suck in air at idle,but leak under boost.They actually work better than a blow off because during shifts the air is recirculated and some pressure is kept in the pipes.That keeps lag down.The BOV's create a overly rich condition when they blow off as well.

Re:Bosch BOV
yes, they do 'suck' air at vacuum, but like stated above, that doesn't leak boost b/c it closes at 0 vac. they're aren't really loud, but they do have a nice flutter/whoosh to them, they actually sound better at low boost, like 5 psi. or so. i have one and for the price, it works and if you're getting a bov just b/c of the sound, you're a ricer

Re:Bosch BOV
You don't really need a blow off unless you're running 1.5 bar or more on a big turbo....

Re:Bosch BOV
Not all BOV suck in air...the OEM's and single diaphragm do...that's why they make dual diaphragm BOV....so it won't open at idle....
Every bov is closed when boosted cause the pressure in the intake pipe and manifold is the same....I think some of you guys need to go back to high-school

Re:Bosch BOV
Well I kinda am a ricer. So what? I want everyone around here to know that I will kick the ---- out of there car who thinks its fast. We have a really bad rice problem here in lincoln. Just today I saw a guy in his white cavalier with spinners on it. Hubcap spinners that is. And with some wack stickers in his rear window. He had his windows rolled halfway down and was just pimping it by himself. But we have worse than that. My car is clean rice. Not dirty rice. Haha. thanks for the info guys
