1st Gen Bov venting

[MY_Game]

I installed a 1st gen uncrushed bov in my 98 gst spyder and a air intake, and for some reason it is loud as ****. I love the sound but from reading many post I know that it is not good for speed and your car. I have everything hooked up and everything plugged and going back to the intake so i dont know where the noise is coming from. I love the noise from the intake, but each time I shift it lets out a really loud noise. I checked to make sure everything is tightly connected, do I just need another 1st gen bov maybe? Thanks for any help!!

is this the first time driving w/ a hard intake pipe? if so , you can ofter hear the turbo spooling and the air intake a lot louder w/ a hard intake pipe. Also check for boost leaks. They can be loud

As long as it's recirculated then there's no problem...BOV's are supposed to make noise when you shift.

Ok yes, it is my first time with a hard intake pipe and I noticed that I could hear the turbo a lot louder, I didnt know that the shifts would be so loud also, but I guess that makes sense if that is where the boost is going. Yes the recirculation tube is connected to the intake so I guess I am good to go. Thanks!!

As long as it's not a fluttering sound, which can meancompressor surge, then it's perfectly normal.

at times you will hear a small flutter though, like say in 4th gear going 25mph and quickly build up 10psi of boost then let off the gas, you will usually hear a little flutter but in that gear at that low of rpms its normal

i'm sure that's what it is also. I remember i was quite surprised the first time I drove with my metal intake, the 1st gen BOV is pretty loud on my car when it's recirculated.

Mine did the same after hard IC pipe was installed. I guess the metal conducts sound better.
