    Vaccum pipe location

    Does anyone know where this vacuum pipe goes?

    It's the on the left hand side of the engine on the side of the cam cover.

    I can't seem to find what it connects onto?

    It should go to the 710N factory equivilent of the dump valve, which plugs into the side of the turbo to MAF boost hose.

      Agree. It goes to the small nipple of the by-pass valve (aka Cut-off valve)
