Breaking news!!
The j20 planned to do 3 Mach wind tunnel test!
It means the design speed was up to 3 Mach+
And the engine will not be al31 finally.

Or it could mean this is a test to see what happens to a Mach 2 aircraft at Mach 3. Ever heard of 'stress' testing?

The engine of J-20 was never the underpowered AL-31FN from the beginning. :P

To me it seems that you are implying that the al-31 or any similar or weaker engine will not be sufficient for mach 3 flight. This is not the case, the mig-25's engines only produced about 22,000 lbs thrust. What is important is aerodynamics and an engine with a low by-pass ration.

true...

Or they could just be testing to see how far they can push the airframe, in order to look for structural weakness and fatigue properties.

WS-10 or AL-31, is simply stop-gap measure at the moment. The WS-15 is the one that will be fitted on to the bird when it becomes operational. Although I heard that Russian AL-31 99m2 (did I get the designation right?) might be a reserve choice in case that plan cannot be met.

The AL-31FM2 is the black nozzled engine of J-20.
