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?

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.

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

i have a 1995 d16z6 with turbonics t3/t4 external waste gate by turbonics type s bov. my bov is t'd at the fpr. wastegate is to the compressor nipple

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?

mij_nagrom88

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

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

Loserkidwac

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
