A study of outflow (OF) and BAL systems in Mrk 231 (and in similar IR QSOs) is presented. This study is based mainly on 1D and 2D spectroscopy (obtained at La Palma/WHT, HST, IUE, ESO/NTT, KPNO, APO and CASLEO observatories) plus HST images. For Mrk 231 we report evidence that the extreme nuclear OF process has at least 3 main components, which are probably associated with: (i) the radio jet, at pc scale, and (ii(the extreme starburst at pc and kpc scale. This OF has generate 4 or more concentric expanding bubbles and the BAL systems. The variability of the short lived BAL-III system was studied. Finally, the IR colour diagram and the UV BAL system of IR+OF+FeII QSOs are analysed. We propose that the phase of young QSO is associated with:accretion of large amount of gas (by the SMBH)+extreme starburst+extreme composite OFs/BALs.
