I know it's a turbo, but that sounds like a quiter version of my stock ATI surge valve. Has that supercharger flutter to it. Wierd.

Could be the wastegate or bov chattering. here is a link to a video where you can here the bov between shifts. It's an rx7 with an apex bov.

What makes the bov chatter?

Here is another vid where the sound I want is more prominent after the burnout takes place.

BOV will flutter if the flow through it is higher then it can confortably flow.

Somehow with my new setup I can hear the BOV AND the compressor flutter during blow offs.... being that one is on the drivers side and one on the passanger's side, its cool to hear the sound in stereo

It has an electronic boost controller, which will do that to most BOV/wastegates whatever. Mine didn't do that when I ran it off the wastegate, now it does with a HKS EBC.
