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. |
