    I think the issue could be the homemade RIP kit, it's not one continous piece of pipe over the engine length, the gap between the two joined metal sections could be acting a little like a reed on an instrument. The joins would be my next investigation area or removing it completely...

    I've put the original pipework on just this week.
    I've done it previously to test that same theory.
    Still did it.

    Really need to have it on a rolling road to try and find the area the noise is coming from. Fat chance of one of them round my way...

    I forgot about one thing. The brake servo.

    The hose comes off the inlet manifold the goes under the airbox through a short plastic pipe and then along to the elbow on the brake servo. I think the elbow contains a non return valve so the servo does not get pressurised under boost (there should be a non return valve somewhere in that line).

    Maybe worth check the pipe / plastic pipe / joints for cracks (or blocking it off at the manifold to test for the howl, though obviously be careful of braking as it won't be assisted).

    It's quite a big pipe too.
