Long story short......same screeching owl/chicken noise when I'm in boost and let off the throttle and the BOV opens. Larger 1/4" ID line, and 7psi spring.....no change at all. Kind of frustrating...it used to sound so good with the stock inlets on the car.
At this point, I guess I will just have to chalk it up as some strange resonance caused by the silicone inlets....I can't think of any other explanation. I guess I will just leave it until I get some different turbos later this summer....probably just put some PR relocated inlets on the car while I do the turbos. From everything I've read, they will get that nice "whooosh" sounds back from the BOV.

Did you tap your intake manifold or how are you using a 1/4" line now?
