BOV question
 

I have a greddy type s BOV on my car and its not blowing off like the one on my old turbo kit. The old one whistled, and this one just flutters can someone help me.

Re: BOV question
 

Where do you have it routed to? Which nipple do you have hooked up?

Re: BOV question
 

check for leaks in the hoses?

Re: BOV question
 

I had this problem before, and like ZeroMR said, it was where I was running the vac line from that made all the difference.

Re: BOV question
 

i have the vac line running to the top nipple and all the vac lines a brand new.

Re: BOV question
 

Where are you running the other end of the line too?

Re: BOV question
 

is it adjustable? might wanna adjust it to soft if u can

Re: BOV question
 

i have it ran and tapped into one of the vac line coming form the intake manifold

and i adjusted it to see if it would make a difference and it didnt.

Re: BOV question
 

make sure the line that you tapped into is a good line. there are vacuum lines that dont actually read a good amount of vac/boost like the evap canister lines are no good. I usually grab the vac line that goes to your fuel pressure regulator or tap into the brake booster line with a vacuum block.

if that doesnt fix it your bov may be locked up. most of the time that flutter is not coming from the bov rather its coming from the wastegate.

it sounds like the bov is not even operating like mine when the line blew off completely.

check those out and i hope it helped

I have a type S bov too. My did the same exact thing your's is doing. I toke mine apart sprayed some brake cleaner on it and put it all back together. I set mine to soft and it worked. Mine was real dirty inside, mite be what's happening to yours.
