I tried to install this all day today, just to see how it would sound on my car. I do intend to do that setup how its hooked into rubber pipe - leading to the throttle body, but wanted to make sure it actually works before I go to all that trouble. The adaptor this bov came with is off a wrx. It has a hose connected on it which is of the same size of small arms that come out of the crossover, where the bov is to be connected. What I've done is used the standard radiator hose, and plugged in the smaller hose this b.o.v came with, into it (as u can see in the picture). and I've got the small pressure hose connected to it as well. But it doesn't seem to work?. all I get is a flutter. and hear no noise at all from what the bov is meant to make. Even though the tubing changes in diameter half way to the bov, id assume it would atleast work still. heres a picture of what I've temporarily done. any thoughts and comments on what may be the problem, thanks.
