    you need turbo compressor map, once you have it you can use this calculator to see max mass air flow it can handle, what is surge and choke line

    here is just example to get basic understanding

    example compressor map of GT1749V, now go to https://www.boosttown.com/forced_ind...calculator.php and enter parameters

    engine rpm example 3000rpm
    engine size example 2.0tdi 1968ccm
    volumetric efficiency example 90%
    boost pressure bar example 2 (this is absolute boost, without atmospheric 1 bar) !

    Calculate

    now you see in calculations Amount of air in lbs/min = 19.6885

    go to compressor map and find on Y axis 19.7
    and find on x axis boost bar

    you can calculate on every rpm and pressure

    Volumetric efficiency varies with rpm !

    Keep in mind that for example 2bar on 2.0 engine is not same as 2bar 3.0 engine, thats why you can see flow
