That was done some time ago and only to the T50-1, since it includes the spin shute and this version will do the high AoA and other aerodynamical tests.

New G-suit gives PAK-FA higher operational ceiling than the Raptor?
Russian Sukhoi T-50 PAK-FA pilots will be equipped with a new g-suit that will allow them to eject from the aircraft at altitudes of 75,000ft (23,000m). If the PAK-FA is able to fly at those altitudes operationally, that would mean that it has a significantly higher operational ceiling than the Lockheed Martin F-22 Raptor
The F-22 is limited by US Air Force regulations to 60,000ft because of the Armstrong Limit, which is found at roughly 62,000ft. The USAF never developed a full pressure-suit for Raptor pilots to wear; instead those pilots wear the Combat Edge ensemble, which counts as a partial pressure suit. Other fighters like the Boeing F-15 or F/A-18, for example, are typically restricted by regulations to 50,000ft (that includes the German Luftwaffe, their Eurofighter Typhoons, as one of their pilots told me, are also limited by regulations to 50,000ft operationally).
There are some very good reasons for those altitude restrictions. Above the Armstrong Limit water will boil at the same temperature as the human body. Basically, if you lose cabin pressure, you will die a slow and horrible death as bodily fluids (except those under pressure inside blood vessels) start to boil unless you have a pressure suit–like the guys flying U-2s (except they don’t inflate those suits normally, which has led to problems in the past–but that’s a whole different story).
IF the Russian Television story is correct–it could mean the Russian have developed a full pressure/g-suit that is capable of operating at those altitudes. Or they’re completely insane–which is also a possibility I suppose.

Vides says they are preparing to mass production. Engine is not ready yet.

Not only that it is going to have even faster speed also
& indirectly
having higher operational ceiling & faster speed would help in increasing the kinematic range of BVRAAM fired by Pakfa

So is the Item 30 ready or not yet? Well if the Soviets managed to make the AL 41 in the 80s that was the first fifth generation engine what is taking them so long to make one now? Or are they waiting for the PAKFA to enter LSP?

PAKFA can do Mach 1.5 supercruise , f22 does mach 1.82. PAKFA ceiling operational 20000m F22 19812m, Max ceiling Pakfa according to report 22400m f22 22700m

PakFA is a prototype with an underpowered engine...
No thats because the final engine gives 171.5kn thrust and 1.5 mach supercruise. The F-22 has demonstrated supercruise speeds of at least Mach 1.7, a difference of 320 knots (593 km/h) indicated airspeed (KIAS) at 40,000 ft (12,000 m).
I DON'T TRUST RUSSIAN NONSENSE. OH WE'LL MAKE NUCLEAR POWERED DESTROYERS BY 2015.... Not even hull is ready. They are just refirbuishing 30 yr old Kirovs. USA had this in SR 71 which flies at 80000ft. F-22 can perform tactical maneuvers at 60000 - 70000ft doing a reverse immelmann turn.
The museum's single-seat F15A, nicknamed "Streak Eagle," broke eight time-to-climb world records between Jan. 16 and Feb. 1, 1975. In setting the last of the eight records, it reached an altitude of 98,425 feet just 3 minutes, 27.8 seconds from brake release at takeoff and "coasted" to nearly 103,000 feet before descending. It was flown in its natural metal finish to reduce weight for the record-setting flights. To protect it from corrosion, McDonnell Douglas Corp. has since painted it in the gray color scheme of most operational F-15s.

Su 27 broke 27 records. Whats your point?

SU 27 broke that record a long time back. The Item 30 engine has now crossed the design phase. And you need to read a lot more about Russian aviation before you run your mouth.
BTW the AL 41 designed in 1980s had more thrust than any other engines that were built that time.
