compressor surge or what, how to fix??...?

ok I have read and searched and read some more but I still cant find a real answer to my problem. My blow off valve sounds sorta like a hks ssqv but It is compressor surge. I have no clue why it is surging. It is on the cold pipe and all vac lines are hooked up properly. The bov is a cheap bov, could it just be cheap broken piece or is there somthing that I am doing wrong.

Are you sure is compressor surge and not bov flutter?Watch some rally races of the wrx's you'll hear compressor surge on them.Mine flutters.......

it makes a sound like swoosh swoosh swoosh sound when blowing off is that compressor surge or just my blowing off sound

Perfectly normal to hear that. Surge is a much different sound.

I have the greddy rs bov and it use to flutter. All I had to do was loosen the spring setting a little and it solved my problem. My bov almost sounded like a gobble. What bov are you using?

[Florida240sx]

If it was a gobble (high pitched) then probably surge.... If it's just flutter like air compressor then you'll be alright...

sorry for so long it sounds kinda like a train going chuch chuch chuch chuch, I can just loosen the bov, btw it is a type rs. i was doubtin it was surge, but I wasnt sure. Would a different bov sound different. I want a straight PSSSSSSSSSSHHHHHH!!! I think that is the ****.

are you recirculating it? if so which fitting are you using for the recirculation? I upgraded to a larger fitting 30mm I think? removed one of the springs and got it to stop, then it just whistled all the time so I said "F" the RS and switched to a 1st gen DSM the only time I got my RS to work right was running open atmosphere but then I got tired of backfiring. *sigh* I've never had a correctly working BOV since going KAT
