atmospheric or recirculating?

[Billman]

I am going to Use it in Recirc mode also. The Question is are these HKS clones up to the Job?

[Billman]

OK, now i need some help-opinions:

This guy installed on his EVO 8-9 a HKS SSQV in recirc mode. He has 2 sound clips.

Is this "The flutter of the small valve" as he states or is it compressor stall due to stiff spring?

"This is normal acceleration. This was to demonstrate the little valve popping even on slight lifts such as casually shifting gears"

"I wanted to try an demonstrate how quickly the turbo spools in this one, started recording in 2nd gear at around 3000RPM then jabbed and let off the gas a few times. Notice that the turbo spools immediately. It was too hard staying in second so at the end of this clip I went into 3rd then 4th"

Vasilis,
I have the non recirc HKS on my RS2, Works great.
You have to think is it worth the recirc or a fast release off boost better?
Mine feels quicker spool up in between gear changes than with recirc.
I hope mines a genuine HKS, it came in a HKS sealed box and is nice quality, just I know how good those ******s are at copied stuff!

On low RPM do you become the same sound? Is it compressor stalling or the small valve?

Do you think will it matter (lagwise) if i run the SSQV in recirc mode or vent it outside?

No I don't get the low fequencey wuffle noise. The one in sound clip might have a gold insert. Don't think its stall.
I don't think you will notice running it recirc way.
