A 170Kn engine with afterburner will also make higher dry thrust than less powerful 140kn thrust engine like AL-41 which makes 86Kn of dry thrust.
Chinese 5Th generation fighter is a disaster because that jet cannot do super cruise and to make it capable of super cruise they aim to make WS-15 dry thrust 125KN and wet thrust 180KN.
J20 can not supercruise because it is less aerodynamic.
With the same engines su35 can easily supercruise.
There are ways to achieve desired speed other than installing big engines .
