    Default Turbo boost pressure numbers.

    2008 207HDi is the car, and in my other thread I have outlined the details.

    My question is concerning turbo peessures.
    I am struggling to find any information about pressures for this motor.
    Is there any source like a graph showing boost at various loads?
    I think this little car is boosting fine, but as my setup can show me realtime boost, it would be good to see how it compares.
    I have searched via google but come up with nothing.
    I may be using the wrong terms I guess, but I have searched.

    Thanks for any help.

    The only thing I recall seeing is a test that measured boost at 1,500rpm (0.4 bar) and 3,500rpm (0.9 bar).

    For reference, perhaps search using the engine code DV6TED4?

    Thanks for the quick reply.
    I work in psi, but I have been looking so I know that your figures seem pretty close to what I am seeing.
    Confirms to me that the turbo seems to be doing what it is supposed to.
    My work car is a Skoda Octavia with the 1.4 t petrol and it goes entirely differently of course. It is a long time since I had a small td and that was auto. This 207 is a manual and with a few years between it and the last I didn't want to trust my memory.

    It would be great to find a graph somewhere, but that is good enough for my peace of mind.
    Thanks heaps.

    I donít think you could compare and get any logical results to many load temp pef saturation variables most modern engines use a reference parameter and an actual if these are close everything should be ok

    Yep, I understand.
    What I was ultimately hoping for was a graph showing boost pressure at different points of a normal accelleration run, including gear changes.
    My setup can give me such a thing to look at, but I haven't yet figured out how to output that data.
    I think I have to pay rather than use the free one, and I am just cheap. ;D

    If performance is off check and clean the vacuum valves that control throttle body flaps and variable geometry turbocharger if you have one

    I will check it.
    Biggest thing as far performance for me is that I run a turbo petrol daily.
    The 207 is a td and it doesn't feel fast - but it has no trouble keeping up in traffic.
    The turbo numbers (as vague as that whole thing can be) look to be good.
    And now the fault codes (other thread) have all gone away.
    It is looking better all the time.
