In some of the videos I've watched, the BOV is the turkey flutter sound. Which BOV is that?

 

i dont know what aftermarket ones do that but i know my friends starion bov makes that sound. i love it....i am pretty sure its also on some rally cars. not sure if that helps but thats as much as i know

 

just stick a turkey caller on there.

 

haha wtf? Turkey flutter?

I've gotta hear this.

 

i think the sound you are thinking of is the waste gate, because i hear alot of WRC cars with a "fluttery" sound its the wastegate opening and closing alot

 

Its so gay. I think Mazda speed Protege's come with them.

 

no... it's not the same as the WRC. In those videos, they took one of the BOVs with the big horn-ish things on it and attached a turkey call.

If your friend's starion flutters, it means it's running too much boost to allow the BOV to pass all the air out. i.e. the BOV is inadequate most of the time.
WRC... they're running very VERY high boost.

 

I think it is the wastegate we're thinking about. I remember an episode of Fifth Gear where Tiff was driving their 200mph+ project Esprit... It made a turkey flutter kinda sound when he boosted; hell he did it twice on film just because it sounded so cool.

 

I meant turkey gobble, not turkey flutter. if that makes a difference

 

ive heard of this also....ima ask my friend, he owns a subie and is into that turkey gobble thing

 

gobble gobble boost

 

It's not the wastegate. It is the BOV, you need to have a BOV with a very hard spring and that will give you that sound IE. Tial BOV or greddy TYPE R, the only disadvantage to it is you are getting compressor surge from the turbo it is not letting all the extra boost out at once that's why it makes that sound.

 

What about the Type XS BOV?

 

turkey flutter makes me think of no bov...

backpressure hitting the compresser would make a fluttering sound.

 

turbo surge= bad

 

i drove my friends modded out fc with the type xs and it deffinately makes that sound...

 

that would be the HKS one...

 

or put a restrictor in the blow off valve port so it forces the compressor to surge while blowing off.

 

There is actually a video with a bunch of guys that attach a turkey caller onto a BOV.
That's probably what you are thinking of.

 

no bov or an inadequate one.

the sound you are referring to is likely compressor surge, as others have mentioned already.

 

wow... if you guys want compressor surges just to have it sound cool.............................................. ..............

******* ricers

 

^^^Uhhh, I dont want a compressor surge. I said theres a BOV that makes a turkey gobble sound, not make the compressor surge. JEEEEEEEZ, lol.

Compressor surge and turkey gobble BOV are 2 diff. things. If you watch some japanese videos w/ souped up cars by big companies, you will hear it. You think the big companies wouldnt know the compressor is suging and the BOV is inadequet and change out for a better one?

 

Your thinking of the dsm guys that taped a turkey call on the end of their bov, thats all they did nothing else.

Signals drift cars dont run BOVs. They said the intercooler and piping were calculated to absorb the shock of the throttle plate closing. They used BB turbos so the compressor surge is supposta be easier on them. They prefer performance to reliability. same as WRC. Makes sense to me. Compressor surge is ok if your prepared to replace your turbo more than once in the motors life.
