dude, the guy in that video used to be on the forum. The only reason his car sounded like that is because he had just installed the fmic and did not have a bov installed yet. A majority of the forum usually tries to get away from that sound. Why are you doing the opposite? There is no performance gain and it definitely does not sound pleasing. By the way, you can't make any bov do a "sequential blow off". I think you may not understand the purpose behind the HKS SSQV. It's called a sequential bov because it has basically two valves. A small valve that opens up for low boost or light throttle release and the entire diaphragm opens up for high boost release. If you have someone with a HKS bov on their car. Have them rev it up a little bit and then rev it up all the way and watch the bov. Then, you will see how the sequential operation works. Two valves work in "sequence" depending on how much boost is being used. Just because a car makes that particular sound does not mean the car has a HKS SSQV on it. A buddy of mine used to have a boosted p5 that made that sound and he was just using a miata bpv I think. It's not the valve that makes the sound, it's simply how much pressure is being released and in some cases, the design of the intake. The intake tube can amplify the sound as well. If you have an aftermarket intake on the car and you get the "turkey". Take your intake off and drive around and you will notice almost all of the turkey will go away. You will still have a slight flutter as you took the amplifier(intake) out of the loop. If you simply think the bov is the source of the sound, you have a lot to learn
