I'm stuck between these two bpvs. The only one I've heard in person is the hks ssqv. I thought it sounded pretty good. But I also like the turbosmart hybrid dual port compact bov. A couple months ago people talked about how great the turbosmart was. From the videos I've watched it sounds like the turbosmart makes a loud psssh sound. And the hks makes a whistle sound. I like the idea that you can adjust the turbosmart. I just don't know what to do or which to go with. Any ideas? positives/negatives about these valves
