Jokes aside, the 117S is not a supercruise capable engine either. It was the 117 which was modified for supercruise.
If the Su-35 is capable of supercruise, that may have more to do with the airframe than the engine, like it is for other aircraft that claim to supercruise.

Developer: "UMPO" (OKB A. Cradles)
Key Features:
Overall dimensions:
length - 4990;
inlet diameter - 932;
Parameters in terrestrial conditions:
thrust at full forced mode, kg - 14500;
thrust at maximum capacity, kg - 8800.
Installed on the Su-35S.
AL-41F-1S - Aircraft Bypass Turbofan engine with afterburner and thrust vector control (UHT) 4 ++ generation, is one of the engine options "Article 117".
AL-41F1S different from the AL-31F increased thrust (14,500 kg vs. 12,500), large TBO (4000 hours against 1000), reduced fuel consumption, controlled thrust vector nozzle and allow the aircraft to develop a supersonic speed without afterburner, which is one of the main requirements for the fifth generation fighter.
In February 2008, "Saturn" reported completion of the test engine AL-41F1S that allowed to begin flight tests of the aircraft Su-35S.
February 20, 2008 have been successfully tested Su-35S engines AL-41F1S.
August 9, 2010 JSC "Ufa Engine Industrial Association" deliveries beginning of AL-41F1S for multi-purpose fighter Su-35s, built in KnAAZ Yu.A. Gagarin, until 2015 a contract to supply 96 engines for 2015-2020 is planned to purchase another 96 engines

Yeah. I know about that.
But when the Russian officials talked about the 117, they said that it is different from the 117S because they have modified the hot section of the engine for supercruise capability.
Most information about the 117S and 117 simply club the two engines together and hence the confusion.
Edit:
What's on the Su-35 is the simpler 117S engine.

117S allow the aircraft to develop a supersonic speed without afterburner<117 allow the aircraft to develop a supersonic speed without afterburner
the difference is more power but both can supercruise

It's a marketing brochure. Don't believe such blanket statements. Even the TBO figure is wrong.
Indeed, we have been told for some time the Su-35 is capable of super-cruising with the 117S, so likely the 117 is an uprated/refined version, which will likely operate at higher sustained temps in the hot-section without damage, you will note that Western fighter aircraft have increased thermal limits over Russian engines. So the Su-35 should supercruise, but to date I have not seen the data on what the actual/claimed capability is??? If you or Bar brother have an article or link, it would be nice to see it, thanks.
There ya go, take that stuff with a grain of salt.
