    Default help with strange noise???

    just wondering if anyone could help with with a noise that is bugging me,
    when im driving along with the window open and i increase the gas you can hear a strange constant farting/air noise which stops when you take your foot off(and its not me) you cant hear it if you sit stationary and rev the engine i think its exhaust related but not sure havent noticed any loss of power etc.
    just wondered if anyone else had had this problem/noise in the past?
    many thanks

    I get a very similar noise from mine, when you accelerate its like a intake of air and when you realise the throttle it like I have a dump valve fitted (which I don’t) the only thing I can think, is its the waist gate realising the excess air??

    Same sound on same engine, thing it linked to turbo spinning up and increase in pressure, I suspect it is a small amount of air leaking from the induction side of the engine but cant be bothered to look for it. either that or it the turbo bearings whistling so have started saving for new one just in case lol
