Today I decided to swap my standard bov on my r33 to a greddy type s and found a dilemma..
The greddy type s is ment to have a loud laser sound that was achieved on my other turbo cars (r32,33x2)
The laser sound was a bit quiet and could still hear the "woosh" that the standard bov made out of the pod even though it's Not re-circulated back the the turbo intake..
So I decided to block the bov outlet with my hand, expecting to here compresser surge (fluttering) but to my shock could still hear the woosh out of the pod filter.
I scoped out the intake pipe and looks all good..
Why is it doing this ??!
