IMO..the BOV should be plumbed back in in the intake pipe PRE-turbo...other wise it won't work....you're trying to balance the air pressure so you don't get turbo stall/compressor damage.

 

If the air is venting on the hot side of the turbo and then being recirc'd back into the hot side...what have you gained exactly? The air is supposed to be diverted to the cold side of the turbo so that the air goes back through the turbo...the right way.

 

This solution would see your BOV hose being about 10cm's long and not going near the turbo that's melting it.

 

You do need a heat shield but some sheet Stainless Steel covering the top of the turbo whould do for your trip to France.

But if it's post butterfly the engine will race won't it? Afterall you shut the throttle to slow down....

Hmm... Think the output from the (non race) BOV would not have a huge effect. Personally wouldn't plumb it there tho.

Correct plumbing would be between MAF and compressor.

I am just gobsmacked that people are fitting turbos with no proper heat insulation. The heat from that turbo, driven hard, will easiliy melt the brake fluid resrvoir, and brake fluid burns like hell. You need at the VERY LEAST a blanket and the downpipe PROPERLY lagging. Any flammable or meltable items near the turbine side of the turbo need lagging too. The tin shields that come in the likes of HKS turbo kits are a joke, you need FAR more than that A turbine housing will give off many kilowatts of radiant and convected heat under full boost.
