hey guys. I have 2 different bov's to try this on. Boost leak tested and no leaks. vacuum lines from my electronic bc and j-pipe is are not leaking at all. first off, we tried a knock off greddy rs bov i got from one of my cousin's evo. I've heard it and seen it work great.
the deal with the knock-off RS bov is that it only gives off the RS bov noise at 15+ psi. Any boost under 12ish boost, it'll flutter. Well, it doesnt flutter, it's more like a couple fast chirps. when we removed my turbo, there's was very very little shaft play, so im assuming there is no compressor surge. we adjusted the spring to it's softest and it's still chirping away, no making any whoosh noise like an RS bov should be.
Onto the real greddy type-s bov, when I put it in, we adjusted soft enough so that the bov would release enough air to be vented(vacuum) when it's recirculated back to the intake. I gave it a couple revs and could see that the bov is working but its not making the noise of the Type-s it should be. It makes a 'type-s' noise very very quietly when it was parked and while driving, I cant even hear it. Basically, both BOV's are working fine, I'm just wondering if my lines from the wastegate, j-pipe and top bov are correct. I'll get pics up asap.
