What blow off valve is on this Supra? I can't figure it out for the life of me.

sounds high pitched, maybe hks or r2d2

 

im talking about the flutteirng.. i assume this is bov and not compressor surge..

 

its an HKS SSQV for sure

 

yeah its an hks, mine sonds like that when I warm up my tires

 

kind of sounds more like this

which is an xr6 which does not have a bov supposedly... which is why you can hear all the compressor surge. Is there any bov that flutters like this? because I know I heard one on a 240 one time but i couldnt catch the guy to ask him..

 

yes the hks will at low boost, it will flutter

 

hks shouldn't flutter...

 

i hear what you might mistaken as a flutter in hte begining, which is actually hte hks opening up and the supra tapping the throttle.

 

i mean i have an hks on my car and it does not sound the same.. this sounds way deeper of a flutter sound.. I dunno, maybe I'm trying to find a bov that doesn't actually exist..

 

does it sound like this because of the distance the camera is away from the car? or the supra hitting a higher boost than my car?

and what about the second vid I posted.. anyone know any bovs that sound like that?

 

its the higher boost level, think about it. the rush of air over that weird shaped piece in the hks.

haha

 

THAT is not a BOV that's compressor surge which in ANY instance is baaaaaaaad

 

lol i know.. there is NO BOV on that car supposedly. i guess what im trying to find out is if there is any bov that sounds like the flutter of that compressor surge lol.. i know ive heard this sound on a 240 and it definitely was not surge..

 

My hks is adjustable, so you have set how fast the boost is released, right now it I have it set at max, so it is really high pitched, abot the same as the supra, and the flutter on mine is the boost needed to open the valve keeps buling boost in the pipe as the compressor slows

 

very very true at fact the fin makes that high pitch whistle sound and like stated above the more air the higher the pitch

 

A True HKS SSQV is not adjustable

 

There is only one other BOV that makes a remotely high pitched sound like that and that would be the TiAL 50mm BOV and it usually only makes that higher pitched sound at higher boost pressures at full spool

 

i have seen an old hks ssqv that is adjustable, ill look a little more closely next time im at my tuner but i do beleave i seen the hks logo on it.

 

I have an old hks on my kit, and they are fully adjustable, and it was a nightmare to find one because the are not made any longer. But my bov does have an adjustment screw in the back for adjusting the air flow
