compressor surge butt bov opens a little
 

>:( what up my compressor is surging at higher boost levels but the blow off doesnt sound like its letting off too much relief air when i let off the throttle. i hear both the surging and a little bit of the bov. what should i do too get rid of the surge so the bov is alot louder likeits working properly?

What type of BOV, have you tried adjusting it

Re: compressor surge butt bov opens a little
 

i have the type s with a nipple on the top and on the side and it is ajustable. it shouldnt surge at all right.

Re: compressor surge butt bov opens a little
 

what are you using for a vac source? Where is the BOV located?
What car is this for? needs some pics and more info...

Hmm the FPR should be good but maybe try it off og a diffeent one to see if there is any difference I like the PCV since its a nice and big vac port...I'd also try and mess with the adjustment maybe lossen it up a bit? a real type s or knock off?

its a knock off .it used too not work at all but i cut 2 rings off the springs in side it and it works a little know. what do i do with the pcv valve then

Re: compressor surge butt bov opens a little
 

I wouldn't be suprised if it just dosn't work but maybe take it apart and oil it or something, I just "T" it off of the PCV vac line...my friends knock off would leak/whistle all the time, i think maybe 1 out of 5 is bad :P

ya cause at idle it is open a little bit but as soon as there is no vacuum it should close right. i take the vacuum line off when it is running and it closes all the way. then when i put it back on it opens a little. shitty bov or do you have any suggestions

save up for a real greddy :P


Can't say I have had any real experience with your problem but I think you might want a longer spring that is not as stiff ??? that will keep it closed at idle and maybe allow it to open better in boost...I am trying to picture how the type S work internally and that makes sense if your original spring was to stiff you cut it for some slack and now it seems to be too loose...HTH
