I've fitted my bailey dump valve now (sounds nice)
But the fitting kit they gave me is wrong. I've disconnected the boost side of the plastic bosch valve and fitted the bailey one there, and pulled off the pressure sensing hose of the bosch one and fitted it to the bailey one. That all works spot on.
Just i've left the bosch valve connected to the clean air side before the turbo. I think with the boost connection and the small pipe disconnected it should stay shut shouldn't it? I don't want unfiltered air being let in.
I don't really want to remove it because the plug they gave me for the hole is the wrong size buy the looks of things. And leaving it there means it takes about 30 seconds to put it back to standard.
