Bov Probs.

just got a BOV and even at max tension i get flutter? its an old BOV, my cousin bought it in 2003, i was wondering if the spring is no good ne more? or maybe more boost? i really got no idea?

cheers

Of course its going to flutter if the spring tension is set to max. Its making the bov harder to open/vent forcing the pressure to try and push its way back out through the turbo.

You loosen the tension to make it vent easier.

ive loosened it up alot but it still flutters slightly then makes the normal noise... i cant think of an accurate word to describe it :S but u know wat i mean.

my mate said somehting about lossening the valve nipple?

try increasing the size of the VAC line that goes to the BOV

failing that, nothing you can do (if you've backed it off totally), it just isnt flowing enough air

Or the spring n it is just too heavy duty, even when loosened.

[joeleo87]

the vac line is pretty long,

my cousin had it on his 32, running the same boost as me and he said it didnt flutter at all ever even when on max hardness.

it sounds better anyway just leave it IMO it doesn't damage ur turbo dw lol

Flutter sounds heaps better. If you want the BOV to actually do its job, get a stock one.

My old trust type s did what you are describing, i know exactly what you mean. Another solution is put the stock panel filter in. It shouldnt flutter with the stock filter in, mine didnt.

you're not testing this by reving in neutral are you?

[joeleo87]

haha nah man, i adjust it and drive around the block a few times.
