another BOV question

[baxsom]

ok
i know that this question has been covered quite a bit but I just cant get it to work
my greddy type s sounds like curly from the three stooges when it opens

it goes whoop whoop whoop phsssssss

i turned the spring all the way soft
no change

should i try the single spring thing that i read about?

 

[baxsom]

ok this is getting silly,
today i softened up the screw so much that it came out in my hand
using the same setting on my profec b that it was before
the boost doesnt come on until 4500 rpms and i still get the flutter on release
i am willing to try any suggestions at this point if anyone has any

 

[baxsom]

i think i finally have it fixed
i rerouted the vacuum line to a different source that came directly out of the manifold with no T's or splices into anything else and now with 6 threads showing at 9psi
i get a clean release with only a slight flutter at 4 psi
i can live with that i guess

The "flutter" noise is do to the BOV not opening to blow off and causing the compresser to serge
