I dont know a lot about them...besides they create noise.

to my understanding they dont create power nor lose power...is this correct?
a SRT4 owner told me this...

88: BOV lose power
88: yea you lose power cuz the airs not recirculated
88: and the turbo works harder
88: i would get one but you lose power

i stated that he was nutz and didn't believe him and he says...

88: do research be fore you talk

 

oh my


I refuse to respond to this because I am trying hard not to flat out call you and your friends complete morons tonight.

 

some MAF based vehicles suffer a snap lean condition due to atmospheric blow off instead of a recirculating valve. This can cause many problems when you replace the recirc with a fully atmospheric venting BOV.

 

The main idea is to prevent compressor surge.

 

It lets out pressure in the intake when you let off the throttle, it's a secondary form of letting out excess boost pressure to prevent "overcharging" your motor as you let off the throttle. The turbine still spins and your throttle plate is still closed, so it has to go somewhere.

Your wastegate lets out pressure from the exhaust end of the system. You need a BOV or have it recirculated back into your intake otherwise you'll damage the compressor housing or blow your motor.

And no, it doesn't really effect power because the turbine is still spinning (albeit at a lesser speed) when you go to shift into the next gear.

 

DSM's are known for this.

 

Ask him if he likes the sound of his impeller stalling.

 

so are scoobarus h:

 

WAAAAAHHHHHHHHHH Pssssssst

 

I was driving along a main road this summer and some guy passes me on the left and shifts right as he passes my open window. The BOV was uber loud. My ear hurt for a while after that. :sad: Plus he broke traction a bit.
