well the woosh is back not as pronounced as before but it sounds great. and i can't tell a lie (to you guys anyway) i had the bv installed ... when removing and installing my old dvs i blooded my hands pretty good so my tuner did the job for me.. and ofcourse the job was done timely and looks great... thanks to ben. here are some pics

 

got the wrong pic here's the last bv pic

 

Looks great! I had one of thoose for a while but never installed it, now I regret.

 

SO how does it sound? can you know here the swoosh in the cabin? would you buy it again if needed?

 

yep it kinda sounds you opened the window, not a real crisp sound like before but way better the a nothing sound. my old dvs almost chirped after a shift, that sound disappeared when i replaced the oem pipeing to the turbos with evo stuff it made a great hp increase but no woosh

 

Steve,

I bet it sounds good. Do you notice any performance difference? As I understand it, bleeding off metered air like that changes the AFR to a richer mixture vs. what the computer is anticipating. Just wondering if you felt any difference?

 

Should not effect if you do not adjust too much to air. I had mine for a while (diff brand but same function), no check engine light and no loosing power, only .

 

nocheck lites all is well car seems to perform just fine.....

 

Has any one tried removing one of the d/v's and fitting a vent to atmosphere valve with a stiffer spring, this should force the majority of the air to recirc but still vent a little giving the noise.

 

my was adjusted to be stiffer as it was relasing with very little boost, still seems to woosh with very little boost, will talk to me tec fri

 

On the old F pipe what is the diameter of the inlet from the old DV, i have access to a lathe at work so may turn down a stainless plug for it and try replacing one of my recirc valves for a Bailey piston DV i have lying off my old car that ran 2.3 bar of boost.

 

thats an agency power bov, correct? I have the same one, even the same color but mine didn't come with the little cone/horn at the end.
It is threaded and did come with a threaded plug to make it 100% recycled. But did you make your own horn or did I not recieve a part?

 

gear the horn came along for the ride as did two plugs.. got lucky i wanted a red one but forgot to tell on order but here it is red as hell....they must be mind readers
