Chris,

Our setup was designed with our Bov's in mind so there are no detrimental effects. However I cannot speak for any other kits on the market. Since you do not have our kit it would be best to consult them before changing anything.

Our Bov's are partially open when not under throttle and can barely be heard when cruising.

Note: The right Bov channels back into our intake box.

Very sexy and "full" looking! I have the CF instead of the blue but am trying to figure out the best way to paint the Active logo a nice yellow to match my brembos and now paddles

Any suggestions?

Chris, here's the link to the exact BOV you'd need with our kit:

You'll need to use the "pink" spring. Tom is right about the "asthma" on DCT though. If you don't mind it, the actual shifts sound amazing.

Tasi polished his to match his manifold

I still don't get the asthma thing? It's either too quiet to notice or because I haven't driven a stock M3 in over a year...

BOV on a SC would be a little too fast and furious for my taste as you get a constant whistle sound when the vehicle is off throttle. Maybe when I was in my early 20's but in my early 40's pulling up to a business meeting or out driving with my wife I prefer just hearing the motor and the exhaust not a bunch of noise under the hood. There is a local SC car running a BOV that comes to our cars and coffee and it sounds a little obnoxious IMO. The owner took me for a few rides and admits that it gets a little old after awhile but he is an old fart like me

This video has a bunch of different driving scenarios. If should give you a good idea of what it sounds like on and off of boost.

I definitely do not hear a constant whistle sound and I'm one of those fast and furious guys running 3 BOV's.

Thanks. I've checked the link but am unsure which flange type to order . As well to confirm pink spring is rated at 11psi. Is that correct. Thanks

Is it possible to vent the current BPV to atmosphere ?

Yes, pink 11psi and tial to Greddy style.

Yes you can. All you need to do is remove the silicon hose from the BPV to the intake pipe and cap the intake pipe.

How is this method different then tail BOV

Chris, there's been change in Tial's designations as of 1/15/12. The correct spring is the GREEN spring.

I already placed the order Vf!!!!!!

Now what can I do? I guess run the pink spring. Blow the engine and have Vf replace it for me under warranty ??

I feel exactly the same way, well said.
