The Tully-Fisher Relation (TFR, Tully & Fisher 1977) has been widely studied during the last decades as it provides information about the correlation between two fundamental properties of galaxies: their stellar or baryonic masses and their total potential wells (e.g. Bell & de Jong 2001). Moreover, recent evidence has showed that the TFR is at place since z=2, but displaced towards smaller stellar masses (e.g. Cresci et al. 2009).   In this work, we study the origin and evolution of the stellar and baryonic TFRs by performing cosmological hydrodynamical simulations which include treatments for Supernova (SN) feedback.  We analyse the role of SN-driven outflows on the origin of this relation and how the TFR can be used to constrain SN feedback models.
