Just installed my porsche 911 turbo BOV... I'm a big disappointed
1) Same spoolup, same performance, etc... this means my stocker wasn't leaking, as I originally thought
2) Boring rush of air sound... I read in a few places that because the valve had a shorter piston or something, it would snap open with a sharp whistle. Maybe I'm not running enough boost for this.
It is a bit louder than the stocker and doesn't flutter though... A decent repair for $65
