I bought a BOV recently that was used but in great condition. I installed it on my car today with a temporary setup that I put together. The BOV seemed to work but it just wasn't very loud at all. It was about like the stock one just w/ a different noise. I tried every adjustment on the screw but it really didn't seem to change that much unless it was all the way up or down. The way I have it setup up and the way it is in this picture is different though. I have 2 different size hoses w/ a PVC coupler in the middle connecting it straight into the stock BPV nipple. I blocked off the Nipple on the intake side and ran the stock BPV vaccum line to the BOV. All connections are very tight. Any ideas.
