"The BIG BOV thread" (Where all bov question threads get merged)

[WuWrx]

did you take the purple insert out?

[s1cksk1llz]

u took the screw out?

[TheWRXstore]

Make sure your vacuum lines are connected properly. The blow off valve wont open, if there's no vacuum to tell it to.

[BiGBlacK97006]

everything is hooked up fine. I put the screw back in. the purple insert is in....but still no sound

[wrxhigh]

it could just be from the flash from his camerabut if you look at the first picture the adjustment screw looks like it has had tools on it in the past.in the second picture the cap nuts around the circumference of the bov also look like they have had tools on them also. you said it was bought new on ebay. was it in the factory sealed hks box or was it just sent to you in another box and said to be new because to me the valve looks like someone has messed with it in the past (like i said earlier could be the flashfrom you camera) if it wasn't i would guestion the ebay seller

[BiGBlacK97006]

yeah the bov was in a different box ill email the seller....thnx

I used to have a 100% Atomspheric BOV, the TurboXS RFL, and although I didn't really mind the sound, it went off ALL THE TIME...like...lift off throttle at 2200rpms, and it would go off.

Also, the 100% atmospheric BOV doesn't recirculate, meaning no air back through the intake. You'll run rich and get worse gas mileage.

If I were ever to pick up another one, I'd go with one that recirculated -- something around a 50/50 set up.

ive looked around at about 2 or 3 places and they are going to sell the HKS bov for $285!!! are they ripping me off?

Hey josh, wouldn't it be the same gas mileage, I mean its not like the car will throw in more gas just because there isn't that extra air in the intake from the recirculating valve. All it does is make you run rich for a second.

try removing your intake silencer first, see if you like that, nice "middle of the road" kinda sound

I just bought a forge blow-off valve and wanted to know what spring to put in for my stock 04 wrx.

[BoostedBoxer]

Please explain to me what the differnce in the springs is. Do they do it by amt of boost?

[IntercoolerOnTo]

they just gave me a blow off valve with 3 springs a red, yellow and green it doesnt say which color to use for stock boost.

is there an instruction manual?

[jungdragon]

use the blue first, if it does not blow off enough for your liking use the yellow one.

red
blue
yellow
green

in order of stiffest to softest

hope this helps
