Standard BOV - out of interest...

Ordered myself a HKS BOV, just waiting for it to arrive. So was checking today how will make it fit etc, and just had a silly thought. Standard BOV releases back into the air filter pipe, and as you know with aftermarket filter it can be heard slightly. What happens if you close up the hole like when you fit a aftermarket BOV, and let standard BOV blow into the atmosphere so to say like the aftermarket type's. Will it work, what will the effects be, does it make a noise etc. Anybody ever tried? Was just wondering.

I think you can answer this one yourself :) Just take the outlet pipe off and take it for a spin to see what sound you get. It only releases air back into the inlet the pipe going from the bov to the efi pipe anyway.

Sounds like a bus door opening.

Make sure you block up the hole in the EFI pipe as you don't want any unfiltered air making it to the turbo inlet.

Thanks guys. So just take the BOV out of EFI/air filter pipe, block the hole and leave all pipes to BOV connected? Can I leave the breather pipe that goes to rocker cover as is or...?

Leave all the pipes connected and just slip the BOV out of the hole on the air inlet. Block that hole up and see how she sounds :)

does this only work on high boost? Do you need to close da hole inorder to hear a sound? Cos i tried it on low boost without blocking the hole and didnt make any noise though???
