2010年11月1日 · The car you are now driving was designed with a BPV. This means that the air that has passed the MAF sensor has already been metered by the ECU and has taken it into consideration. That air must remain in the system or you will experience a sudden momentary rich condition if it is suddenly vented to the atmosphere.

2004年12月13日 · and these barely more audible sounds, i.e. bpv and intake, are only barely noticeable when you are doing more than just cruising. before i put in the elbow, i read some posts stating that turbo related and intake related sounds became more apparent; this is what i was hoping for. but after the elbow mod, my car sounds pretty much the same.

2024年4月22日 · That's what happened to me anyway. All of a sudden, driving the car, it started making a new flutter noise while under boost. Normally I can hear the BPV dumping when I let off the gas, but in this case: The noise was new, it didn't do it before; It happened while under boost; I replaced the BPV, car went back to normal.

2014年10月16日 · The Stock BPV is a well made great unit, and most times there is no need to replace it. There are some reasons for replacing it though. You maybe running a larger turbo, running more boost, or you could have an older car, with a valve that has started to become leaky under boost conditions.

2024年11月14日 · Okay so i can confirm i had some kind of leak. Car now hits 24 psi (target 20.5) after switching to the grimmspeed BPV. So i got tuned on a leaky BPV. Sunday i will smoke test all the lines. If no leaks, i will talk to the tuner because there is nowhere else to look.

2007年12月31日 · thanks for the advice. also another thing is.wen i did the FMIC.when i first installed the BPV onto the flange with the FMIC,i didnt use any silicone sealant and i used the old BPV gasket.AT that time the BPV was sounding like SWOosh with nuthing sounding like surge or anything.I than realized i am an idiot for using the Stock gasket. i took it off again than silicone sealed it in between the ...

2006年11月24日 · Also no running issues witht he car, and i know my car doesnt like 100% atmos bov,s i had a forge 100%, sounded awesome but made the car run like poop. Than i switched to a forge 100% recirc bpv, nice but not the sound for me. now im happy with the worx. its a DS1 btw

2006年3月20日 · The only problem is that most of those threads are filled with "it sucks" type of comments, or inaccurate statements like "it will make your car run rich", etc. Heck, even your own post says that. IMO what is needed is a definitive description of the function of the BPV/BOV, along with actual real world impact from running an atmospheric BOV.

2010年7月20日 · Crawford runs without BOV/BPVs if I recall correctly. There's a theory that BPVs exist primarily to prevent customers from asking car manufacturers what that weird chuffing noise is when the they lift the throttle.

2007年5月7日 · A lot of aftermarket bpv do both vent to atmosphere and vent to intake and there is no third connection. You should see a small vacuum line from the valve that tells it when to open, and a larger opening with a flange of some sort on it that recirculates air back into the intake stream (after the MAF).
