Currently I have an atmospheric BOV mounted on the cold side of the intercooler, down on the L/H side before the throttle body.

Damn locusts have splattered the whole front section of the car. As soon as they hit the front bar at speed they explode and cover everything behind it

I am changing it to a plumb back BOV for obvious reasons and want to know where to mount it.
If I keep it in this spot I have to run a really long hose to return the vented air back into the intake.
I would rather take of the hard pipe on the hot side of the intercooler and weld an adapter on there, thus only running a very short hose to the intake

Does it matter where along the intercooler piping I mount the BOV or is this irrelevant?

General rule of thought is keep it as close as possible to the Throttle body. Brenton from Fours N More made a plumb back setup for mine using a length of electrical conduit plus rubber connections. He just heated the pipe for gentle bends and when he had desired shape painted it black. The pipe runs along the bottom of the engine near the radiator bottom edge. Very stealthy and works a treat. I would take some pics to show you, but as its black and well hidden there is no real point as you really can't see it easily :) . I think you should be able to nut something out as you have proven you are pretty handy mechanicaly from what I have seen so far :friends:

Aww thanks Darren,
I do like to tinker around thats for sure.
Thats just what I needed to know, its not a big issue making up a hose to run the length, it would have just been easier. I like brentons idea, I will probably do something similar.
ATM I am tidy'ng up alot of stuff under the engine bay as I have hated it since I got it. The HID's that came with the car have like 3 seperate control boxes, god knows why but they are layed out everywhere. I want to move them out of sight.
One other thing I am contemplating is cutting a circular hole under where a pod filter would usually fit, and run the intake pipe through that and house the pod in the opening in the front bar. I would ofcorse build a box around the pod to keep the dirt off of it and make a scoop going into the box for direct cold air induction.
The only thing I am a little unsure of is cutting holes in my baby, I know the finished job will look good but errrrrrrr.
The other option was to just extend the intake pipe a little to move the pod forward and then build a heat shild inside under the bonnet and have it cooled by directing the air from the front bar into the pod
