Im equipped with an hks ssqv right now and the thing is damn loud, a friend of mine said he could hear it about a block away. in my opinion thats rice, as its much louder than it has any business being. so in that case whats a decent bov i can find used that doesnt make a **** load of noise. any suggestions, any experience? im open to anything as id rather not be too obvious about whats under the hood.

 

just keep it. i have the older hks sbov. the ssbov sounds really good!!!!!!! don't waste your time changing. it would be rice if your car was N/A

 

Unless you route your BOV back into the intake they'll all be loud.

 

ahah, i just ordered that one, everytime i've raced every has asssumed i've got a turbo, so i personally i don't care, they won't have to ask anymore. lol

 

ah, well if theyre all that loud ill just not worry about it. loud is better than not at all in this case :P

 

i installed the same blowoff valve on my friends wrx, and his **** isnt loud. isnt it true the bigger the turbo the louder it is.

 

well the more air it has to pass, the louder it will be

 

stupid question ... but what does he bov do?

 

Vents boost during shift, that way when you let go of the throttle, and the throttle plate closes, the excess boost travels back towards the turbo. Before it hits it though, it gets vented by the BOV because if not damage to the compressor wheel can occur.

 

the blow off valve also, gives quiker spool up between shifts, as the unwanted air is released and isnt making a nuisance of itself...lol
