Holy Molly... I had the volume way up when I opened that link! lol

how ironic

The little bolt on the back is adjustable. Loosening it makes it louder, tightening makes it quieter. But if you can't tell if you have an aftermarket BOV or not then I wouldn't go messing around in there. Ask a friend who knows a little about cars to help you out.

i have an hks BOV and its obvious, its shinny it has a purple center and says HKS on it.....if u don't see any of that you probably don't have it. if you do mess around with the black bolt behind it. I agree with bluerex though if u dont know if its an aftermarket BOV don't mess with it. Go to an aftermarket performance shop instead of regular mechanic they will probably be much more help to your question

c'mon guys,
Who here can say they havent enjoyed , at least once, the snap of their BOV.

I admit it, I am a noob who so far only uses info contributed by others. But why does everyone who hates BOV's have to post in EVERY thread about them saying how stupid they are? We all understand your position! Now move on to blue headlights or something! :-P

The stock BOV is really loud. It makes a cool whooshing sound even at low rpms. IMO, the aftermarket bovs tend to sound like chirping birds. Since your car appears to be near stock, the stock bov might be best.

With a mellow exhaust, the turbos spooling is really loud. I think "turbo whine" noises are cooler than blowing off or loud annoying exhaust.

b/c only dumb **** kids have them.

I actually only really like one type of bov. It's the OLD HKS style. They no longer make them anymore. Just one solid whoosh. Not a fan of the chirps and other tones.

When I drive my TII with a bov and then my FD with out a bov, I do miss the bov sound.

So yes, I do enjoy a nice bov.

You and Michael Jackson both.

I enjoy the sound of a good BOV, and it gets about as much attention as my exhaust, turbo spool, engine revs, etc. tone(s) would. Its in line with any other visual/audio stimuli coming from the car, and the way the car sounds is obviously more critical to some than others. I have no real rice-phobia when it comes to the BOV, so to each his own.

Fast vs. Furious:
Enthusiasts from different backgrounds clash in their opinion of blowoff valves



Pressure Relief
The Charge Relief Valve (commonly referred to as the Blowoff Valve) is a key component in any turbocharged vehicle. It vents excess pressure when the throttle is closed in order to prevent compressor surge and help prolong the life of the turbocharger(s). The factory Charge Relief Valve is plumbed back into the airbox, to maintain a quiet and consistent engine tone. In cars with extensive modifications, the factory Charge Relief Valve may not be able to cope with the increased pressure that is produced by aftermarket turbochargers in the constant pursuit of ungodly amounts of horsepower. For these vehicles, and aftermarket Blowoff Valve is necessary to avoid turbo damage.




Rushing Air
Aftermarket BOVs vent their pressure to the atmosphere, yielding a loud 'whoosh' or 'pssssshhhh' sound as the pressurized air is released. Many people find this sound pleasing or 'cool.' Young enthusiasts often associate the blowoff valve sound with fast cars, because most high-power turbocharged racecars are equipped with loud BOVs.





Imitation, Flattery, and Loud Cars
Many younger enthusiasts cannot yet afford to modify their cars as extensively, or choose not to due to reliability concerns. Wanting to sound as cool as the racecars they see on TV or at the drag strip, they often purchase aftermarket blowoff valves to make their car sound cool also. It is not uncommon to see an otherwise stock VW Jetta 1.8T with an aftermarket blowoff valve, revving their motor at a stoplight to make the 'whoosh' sound in an attempt to impress their fellow students. What many of these kids do not know is that an improperly tuned BOV will decrease engine power by venting too much pressure each time it makes the 'whoosh' sound.




Conclusion
Are aftermarket BOV's a threat? Should young enthusiasts be chastised for wasting their money? How much boost can the factory CRV tolerate before it becomes a liability? Does a twin-turbocharged motor require two blowoff valves? All of these questions can be answered in many ways, and the responses will differ depending on who you ask. There are two common viewpoints with regards to blowoff valves:




BOV's from a racer's point of view:
Is is lighter than stock? Will it make more power? Will it make me a target for law enforcement harassment?



BOV's from a ricer's point of view:
Is it shiny? Does it sound 'cool' like Gran Turismo? Do all the JDM drifters have one?




It is not the intent of this article to make any recommendations for or against blowoff valves, only to educate the uneducated with regards to the history and common uses of Blowoff Valves as they relate to turbocharged vehicles.
