Click on the 2nd movie, about 2 minutes into it. Is that what the HKS SS BOV sounds like?

 

mine definately doesnt sound like that. it flutters a heck of a lot in that movie.

 

Yes and no. You have to run above 10psi to get close to that sound. Any pressure under that its pretty quiet. I am pretty sure thats it though, if not its another dual chambered BOV.

 

Yes. My HKS SS sounds fairly close to those. I am running right at 10 pounds of boost.

 

CFM will change sound more than simply going to 10psi on a small turbo. My friends supra with T71 and 2 SSQV's sounds just like this. But my T25 with 1 SSQV is louder and sounds less like the one in the video. It is cause thoes cars are moving much more air

 

yeah that is a hks it even has that on the side of the car i think he might be blowing the ssq out the front bumber so home you can see it on the driver side in america side of the car. if that makes any sence
