The 14 tons WS10 declared ready, likely after extensive tests on J16, J15B & J10B.

I thought they successfully test this engine last December So this article is kind of flash back
J-10C with homemade engine conducts trial flight
Posted on by —
Recently Chinese military fans took pictures of a J-10C fighter in trial flight. J-10C is an improved version based on J-10 fighter jet (NATO codename: Firefly), and is said to be positioned as a fighter bomber.
It has been reported in May that J-10C had successfully tested China’s homemade FWS-10B engine, with stronger thrust than FWS-10 and additional FADEC system.
J-10C can take over four tons of ammunition, and is equipped with a targeting pod for launching precision-guided munitions. This kind of pod is reported to be similar to Israeli Rafael Arms’ Litening pod, of which a newer version is also used by U.S. fighter jets.
Some analysts also said J-10C is an improved version of J-10B, of which the production has been stopped. Compared to J-10B fighter jet, J-10C has improved electronic system and uses homemade improved engine, while other parts are just the same as J-10B.
Production type J-10B fighter
This judgment is based on serial numbers of both types of fighter jets. J-10B type began its test flights in December 2008, and a J-10B fighter numbered “101” appeared in the second half of 2013. According to Chinese new-type aircrafts’ traditions, “1XX” number indicates that trial fight has ended, and formal production will begin.
A prototype numbered “201” similar to J-10B appeared earlier this year, but it is different from production J-10B in some aspects. It has antennas both beneath the nose of the aircraft and on the back. Judged from the convention, “2XX” should be a largely improved version of “1XX”, so experts concluded that that was the rumored J-10C.
a lot of stuff came out here.
Sounds like WS-10B has achieved design certification by sometimes 2014, so mass production of it must have started already. That probably explains why we saw the 2 J-10Bs flying with it at end of last year. WS-10B must have been already tested and in service with J-11Bs and J-16s before they were comfortable testing it with J-10B. So I would imagine at least a portion if not all of the J-11Bs and J-16s from since start of 2015 are using WS-10B. Also of note is that the original FWS-10 has achieved production certification, so the initial overhaul for FWS-10 is 1000 hours. Remember, the long endurance testing to achieve design certification was 300 hours, so this shows the progress. Now FWS-10 first achieved design certification in 2006, but it was not really installed on J-11B until 2008 when they found the problems. If we say that production certification was achieved by 2014, then it took in reality about 6 years to achieve production certification. Considering that it took 3 years for WS-9 to do this, it shows you how much work was required when you are developing a new engine vs cloning one.
Also sounds like WS-15 has entered into the phase of achieve design certification sometimes in 2015 after 7 years of tests on the testbed. It's probably another 5 years from design certification (2001 to 2006 for WS-10 I think)..

Were any specifications like thrust leaked?
Hmm ... but isn't the WS-10B the version for the J-10 with the gear-boxes mounted to the bottom - similar to the AL-31FN was derived from the Flanker-used AL-31F - and as such it simply could not be installed in a Flanker ??
Any idea when we can see one installed in a J-20 at best ?
I think it's been known for a while that this is the 14 ton thrust engine.
you can never be too sure on this, but the Chinese sources indicate that it was flown on flankers first before J-10. So I can only assume that there are 2 versions with different gearbox location.
