This HKS SQV blow off valve is a "dump to air type" of dump valve, while coupe is designed to use re-circulation dump valve, so what is the point to alter the original design when there is no additional benefit, extra $$$ expenditure plus the "Pisssss" sound, that's all...................

...i am lost.

Just use a re-circulation type, simple & easy!

Simon

Patrick is correct.
Just because the the air pressure lost is minimum in recirculation type.
This HKS blow-off valve is dump-to-air type, if the dump to air quantity is not adjustable, it is not good. But since, this HKS SQV has 2 level of dump to air, it seems to compromise the sound and the performance.
So, I want to know if anyone has a field test report.

everybody said circulation type is better for acceleration

It is about $1000.

so i suppose it can improves the performance during acceleration as the pressure lost would be minimized when changing gears?  (Sorry, i am a mechanic idiot) Good bor.....tempted.

It is about $1000.

According to the literature, you can turn the sound too...
"Triple Fins set at the center of the funnel produces a
dynamic and aggressive sound. An optional special Round
Fin can be purchased separately for sound tuning.
■TripleTriple Fin design produces “Super Sound” "
