Stupid Flutter

[R34NRG]

i just installed a air filter and now i have that annoying flutter sound. is there anyway to get rid of it without taking off the power intake?

[LTHLRB]

standard bov...

[Mr. Oizo]

unblock your stock bov.

[R34NRG]

u mean if i dont want the flutter i need to get rid of my BOV?

[LTHLRB]

no u need to re connect your bov to stop the flutter

[R34NRG]

could u explain a bit more i really dont know much about intake....

where would i reconnect my BOV to

[Wink]

Plumb it back so the air expelled from the BOV gets fed back into the air intake.

did you remove your BOV? or block it up? or do anything to it?

[LTHLRB]

the nipple on the bov should have a hose connecting onto the intake manifold, the outlet/mouth of the bov should be plumbed into the intake pipe/hose on the mouth of your turbo. The bov its self bolts onto your crossover intercooler pipe.

no.....all i did was add a pod filter...my BOV is still attached...but its being drowned out by the flutter

the previous owner might have done it

take a photo of your engine bay with a closeup of the bov area

[LTHLRB]

my flutter stops all together when the bov is re connected...

[R34NRG]

i dont know what i was suppose to take pics of so i just took a bunch...here they are.

The exit of the BOV (circled in red) should have a hose going from it back into the intake pipe (the large pipe which the air filter is connected to)

[R34NRG]

how will i hear my BOV then?

[Wink]

how will i hear my BOV then?

You won't be able to.

[R34NRG]

but thats wat im trying to fix....i dont wanna hear that flutter noise because its drowning out my BOV (wooosh) sound. i want to hear the BOV not the flutter

[Wink]

You can't - the flutter noise comes from the BOV.

[R34NRG]

.....hrmmm maybe im not gettin something but before i had the power intake installed my BOV made a totally different sound...

[RaseR]

OMG - The flutter sound does not come from the BOV....It just means your aftermarket BOV is set too tightly and most of the air is reversing back through the turbo getting chopped up by the impeller hence the 'flutter' sound...You couldn't hear it b4 because your airbox muffled the sound.

Back off the adjustment of your BOV to make it open up earlier and your flutter will be gone....even better chuck on the std BOV, they're pretty good until you start running high boost levels.
