B-Man Posted August 12, 2002 Share Posted August 12, 2002 OK, what is (Manufacturer / Model / Brand) of a BOV that does a little of the 'schhhhhhhhh" sound , but won't be loud enough to get you in trouble with the cops ? (Oh, an not scare the Bejeezuz outa people on the street ??)

PranK Posted August 12, 2002 Share Posted August 12, 2002 not mine! (Blitz) and don't mount it in your front bar. Any really... if you have them adjusted like i have mine, they won't sound until high boost (where your exhaust is making a crap load of noise as it is) but a turbosmart one or GFB one will pshhh but not be too loud.

Guest Initiate Posted August 12, 2002 Share Posted August 12, 2002 I only have a std BOV but my APEXI Power Intake makes the normally quite quiet "psssh" sound more audible now.

Silver-Arrowz Posted August 12, 2002 Share Posted August 12, 2002 If it's not OEM, Cops will make a fuss of it if they want. Link to comment https://www.sau.com.au/forums/topic/2526-different-question-on-bovs/#findComment-45875 Share on other sites More sharing options...
400HP Posted August 12, 2002 Share Posted August 12, 2002 Many BOV's have adjustible springs or whatever that allow you to change how loud it is. Link to comment https://www.sau.com.au/forums/topic/2526-different-question-on-bovs/#findComment-45877 Share on other sites More sharing options...
franks Posted August 12, 2002 Share Posted August 12, 2002 are you sure about that? the spring regulates the activation pressure to cater for a wider range of pressures offered by turbo's and supercharges... wether it effects the sound could be a spin off of that...

B-Man Posted August 12, 2002 Author Share Posted August 12, 2002 Maybe I'll stick with the factory one - I do know that with a Pod on, the standard BOV vents a little back thru the POD.

400HP Posted August 13, 2002 Share Posted August 13, 2002 Well yep Franks..... I believe basically (I'm don't guarantee this) but if you relieve more pressure its loader... and less presure is quieter... We'll see at the end of this week Link to comment https://www.sau.com.au/forums/topic/2526-different-question-on-bovs/#findComment-45969 Share on other sites More sharing options...
B-Man Posted August 13, 2002 Author Share Posted August 13, 2002 Wouldn't that mean that the BOV isn't working as well as it could be?? Link to comment https://www.sau.com.au/forums/topic/2526-different-question-on-bovs/#findComment-45974 Share on other sites More sharing options...
PranK Posted August 13, 2002 Share Posted August 13, 2002 no, i think thats wrong. my BOV has been tightened so that it doesn't open until about 5 or 6 psi... anything below that makes my turbo flutter because the BOV isn't opening. it makes no difference to sheer volume.

franks Posted August 13, 2002 Share Posted August 13, 2002 400HP i dont think there is such an animal Prank, if your BOV is still fluttering wouldnt it mean you need to loosen the BOV?

PranK Posted August 13, 2002 Share Posted August 13, 2002 yeah, thats what i was saying.. i tightened it so that it wouldn't go off until higher boost... i like being able to drive semi quietly.

adam 32 Posted August 13, 2002 Share Posted August 13, 2002 careful you dont tighten it up too much as otherwise itll be forcing pressure back onto the turbo which is what the BOV is meant to stop...

PranK Posted August 13, 2002 Share Posted August 13, 2002 yeah but its opening at 5psi+ you wont cause damage to the turbo with backwards running pressure until 10psi+.
