BOV? which one?!!! Please read!
 
Hey guys/gals, which BOV makes the crazy sound in those JDM drift cars? Like, it doesn't make a single "Pssshhhhhhhh." It makes a series like...."PSsshhh.Psshsh..Pssh..Psh...then kinda fades away." WHICH ONE?!?!?!?!?!?!? ;D

Drift cars are usually feathering the gas pedal so that is why it sounds that way instead of just shifting and hearing it once.

I know what feathering the gas sounds like! but the bov I'm speaking of sounds like a series of compressed air. What does the HKS super sequential sound like?

Its the free one called wastegate flutter.


But the only BOV that does that his the HKS super-sequential

This is the way wastegate flutter or compressor backspin sounds like. Disconnect your BOV and take it out, you'll hear what I'm talking about

Re:BOV? which one?!!! Please read!
 
if that's the case, then all turbo charged cars like GTi's and the like should be making this sound too with out a BOV? Because my friends GTi 337 doesn't do that, I can only hear it spool.

Yes, all turbo cars (except diesels) will make this sound if you disconnect the BOV, even your friends GTI

I don't think he does

Ummm..I'm not looking for one big "PSSSHHHHH." I'm looking for the quick and alot of "pulsating" or "series" of Pssshhhh's! Any of you guys play Sega GT for XBOX?! I think it's the supra or the RX-7 that makes this sound..

zerovandez 08-17-2004 10:55 PM

Re:BOV? which one?!!! Please read!
 
I got it! It's like what I thought and what Whitey said...It's the HKS SSQV!! I shouldn't have said it was a series of sounds...it's stages of compressed air, "like a turkey getting hit by a car."

The tial bov does that, I heard one on a turbo ls the other day and it sounded wicked.

Re:BOV? which one?!!! Please read!
 
No the tial bov doesnt do that, I've had the tial bov on about 5 different turbo setups and we have used tial bov's and lots of different cars. They sound pretty normal. Kind of like a "whip" sound. if you are hearing "flutter sounds" that would be called compressor surge. IMO the HKS SSQV sounds like ass.

This is a joke but it sure will give you that flutter sound you want.Stick a ------ turkey call in the exit of your bov that ---- will make a flutter nose like no other ;D theres a vid posted somewhere of this on a dsm.Its funny as hell.

"...."PSsshhh.Psshsh..Pssh..Psh...then kinda fades away."

The only thing I can think of what you are hearing is a shitty blow off valve going off late and your hearing a combination of compressor surge and the blow of valve.

Compressor surge fades away just like that, it sounds retarded.

I probably described it all wrong. Damn some of you have to watch option videos or play Sega GT on xbox!

yeah, i'm very familiar with the sound :P my bov didn't even work for about 4 mos. and i just figured that was how my bov sounded ::)

This kind of sound happens w/my Turbo smart valve when the spring is too heavy or too many washers are installed - like the pressure can't quite open the valve all the way.

why are you so concerned with the sound of the BOV? You should be concerned about spool times, turbo efficiency, engine management, and tuning.

Damn ricers.

The Drift cars are pushing lots of boost and they stay in medium to high RPM's, CONSTANTLY blipping the throttle and making adjustments. What would constantly blipping the throttle do on a car in the high RPM's with a lot of boost do?

By golly it would make the BOV sound a bunch of times!

Get a ------- 1G DSM BOV for $50. You'll be happy with it.

Re:BOV? which one?!!! Please read!
 
the black bosch BOV's make that nice fluttering sound with the right amount of boost....and the drift cars that you hear blowing off its not blow off...its compresor surge...the real drift cars go str8 from turbo to IC then IM....no lag....the flutter isnt that loud but its audible...hope that helped you with your search.

how exactly does that make no lag? the compressor surge would stop the spool


that turkey call video was funny

no ---- right, no bov isn't very efficient, the turbo stops every time you let off the throttle b/c the compressed air 'surges' back in to it instead of being realeased out of the bov, therefore making the turbo have to spool up in every gear instead of staying spooled.

I know which BOV your talking about. It kinda reminds me of a Salt Shaker

needahonda 08-21-2004 03:42 PM

Re:BOV? which one?!!! Please read!
 
its not the BOV its cause they have a (big)turbo that keeps spinning creating boost so it flutters the BOV.

FooK 08-21-2004 07:27 PM

Re:BOV? which one?!!! Please read!
 
There was a Blitz BOV out that you could put an insert on the end of and it would make the sound you're thinking of. What I would describe it as is a Rattle Snake.
