... We present simple stellar collapse physical model which allow us estimate the time evolution of the most important physical parameters of Black Holes --- mass and specific angular momentum and disk formation time. ... The disk accretion play important role in acceleration of BH rotaion. The BH specific angular momentum can reach value more than $0.9$ for wide range of stellar envelop angular momentum. Then with out disk accretion in case of power low stellar envelop it limited by value $0.45$. ...
