BOV Discussion Thread
I have one but i haven't turboed my car yet. still waiting on the intercooler. But What I was wondering is how the bosch BOV sounds. Does it have a whistle to it or is it just a WHHooooosh? Cuz if it doesn't I want one that does.

Re:Bosch BOV
So are you looking for a whistle or the woosh?

Re:Bosch BOV
Stock dsms give off a nice throaty wooosh when you take off the piping and give the accelerator calbe a quick turn.. every BOV acts differently to every engine/turbo setup.

Re:Bosch BOV
Alittle trick to vent the Bosch into the atmosphere is to install a one way valve from a septic/well system on the end.The Bosch valve is a bypass valve,not a true BOV.It bleeds air just above idle.

Re:Bosch BOV
So you are saying that when at idle it is sucking in unfiltered air. That would mean that I would be loosing boost when it gets boosted or not? Would the positive pressure of the boost on the vac line close it when boosted?

Re:Bosch BOV
BOVs aren't supposed to suck in air at idle or any other rpm range, DSM bov's definately don't.
