Yea, thats about the turth. Nathaniel had one for a little while. He said it used to make a noise when he first had it, I always thought it was quiet but I didnt know him when his made the noise. The bottom oring is completly shot on it now and I gave him a different bov to try. I think the only reason his worked for him so long is because he car uses a map sensor.
And btw, if you adjust it all the way hard, its not going to blow off. When you have that bov adjusted all the way hard your not even allowing the spring to work, the adjusting bolt completly holds the piston down.
Your hearing compressor surge and thinking it sounds cool (which it does) but is bad and you dont even need a bov for that.
For low hp a hks bov will work just fine. Turbo xs works good too but I dont think they are great for lower boost applications. Even with mine all the way soft I hear a little surge before it blows off if I get like 3 lbs on a shift.
