Did I not call it or nah :)

Still, nothing remotely close to an official confirmation. I wouldn't encourage parading this claim around as gospel but more so a mild expectation (or better yet no expectation at all).

What would be the thrust to weight ratio of that was the case?
Assuming a similar (most likely slightly higher) wet weight to the EJ200 and F414 (≈ 1000-1110 kg) it's easily 10+. But my expectation is ~9 under the strictest parameters/operational conditions.

I think it's likely the engine is capable of 120 kN. Whether they'll run it at that or go with a lower figure to conserve life-span is what's really debatable. They might do the latter, as I've often heard that the WS-15 is capable of being pushed much higher than its commonly cited 181 kN figure but for the sake of increasing its life, it is run at that "only".

Given the base AL-31F spits out almost 123 kN the 19 is pretty much guaranteed to be able to produce 120+ kN if pushed hard enough (as high as 127 kN afaik).

But yes, I expect the installed thrust to be not as exaggerated, closer to the high-110 kN.

isn't chief designer mentioned T/W ratio of 10.. but maybe later on requirements changed with higher thrust.
