I recently changed my BOV to recirculate and now I am getting really bad flutter. Any ideas what this is? I am a newbie to the evo scene, and never had a turbo car. Any help is appreciated.

 

is it an ajustable BOV? what Brand is it?

 

it is a turboxs BOV and it has the screw at the top. I tightened it snug but not tight...

 

Your BOV has a really stiff spring, hence the flutter. You can un tighten the spring to get less flutter.

 

To fix this, you need to adjust your BOV. Most BOVs have a screw or nut to adjust the

tension. You can turn the screw/nut to the right and increase the tension. Do this several

times with a test drive in between. If your BOV stops letting out the pressure, you have

adjusted it too tight. You will then need to start adjusting soft again. You must keep

playing with this adjustment until you get it just right. A good adjustment will allow the

BOV to release pressure after slight boost, and not stall afterwards. It is not necessary for

the BOV to release pressure when you rev the car.
good luck

my stock bov flutters at low rpm =/ but holds boost well and sounds great in high rpm. Sux to drive around block making turkey sound
