Like many of you I'm running the A&A Turbosmart BOV.

I set the initial position of the BOV as per the A&A instructions. However, I've never heard anything sound remotely like the typical blowoff noise associated with blowoff valves. Is this normal, or is it possible that I have it adjusted too light and it continuously vents and, thus, I don't get the blow off "pop...pssssst" noise?

How should I check this and adjust this?

BTW, I'm making the boost I expect as per my boost gauge. I've have the P1SC A&A kit running the 4.25" pulley (heads, cam, headers, etc.)....does 5psi seem too low for this setup?

I just took the filter off mine yesterday to try and get it louder and it didnt change much. The only time I can hear it is if it echoes off something next to me and even then it just sounds like flutter. Ive Youtubed some Turbosmart bov's and they all seem pretty quiet. Ive read if you want it louder to try out a Tial.

I didn't mind the turbosmart being quiet when I had it. Your more of a sleeper like that. I also like the Tial BOV's but your not sneaking up on anyone with it so pick your poison.

If I rev it up in the garage with the BOV side right next to a wall I still can't hear anything that sounds remotely like a BOV. It seems like it must either be constantly blowing off boost or never blowing off boost. Is that possible? It revs and recovers pretty good so it must be bleeding off boost at some point. Maybe Im expecting too much from 5psi?

Your probably not going to build much boost if any reving it in neutral,
you need to have the engine under load.
Try a hard/wot 2nd to 3rd run w/windows down, you should be able to hear it then, somewhat.
If its not loud enough get a different bov/bypass.
