i've read after action reports where pilots were claming that they run WEP for much longer then 5 minute with no damage to the engine.

I've seen the same, but I'd imagine that when a guy resorts to WEP, there's a good chance that keeping time is the least of his concerns.

Yes, as any bullets, if they have no HE. By the way, once I saw MDZ Soviet/Russian HE filled bullet 12.7 mm effect on thin aluminium plate - it was a hole about 300 mm diameter.

Imagine what a 3cm shell would do.. Hope to see that realistically implemented in DCS.

The us navy and army actually wanted 20mm autocannon to replace the .50 back in 1941 before Peral harbour.
and the US went to some lengths to produce a copy of the British Hispano mkI. which itself was a copy of the French Hispano-Suiza HS. 404.
but they could not get it working reliably
this was the A/N M1 20mm
in 1942 the British sent them the Hispano mkII and the US created the A/N m2 20mm
but it still had reliability issues. the British refused to buy it. even though they needed more Hispano.
the US had stockpiled 40million 20mm rounds by this point.

the A/N m2 20mm was finally used in the p-38 but because of those reliability issues, that was it.

late in the war they produce the A/N m3 20mm which saw some service on the f4uc but the marines preferred the .50 for the obsolete Japanese planes. and it was still unreliable.

finally after the war a reliable version the m23 went into service.

here is the manual for the m1 and m2

https://archive.org/details/20mmautomaticgun00unit

apparently it had a larger chamber than the French or British guns and was prone to light strikes and stoppages and needed some form of cocking system to clear the duds.
the british didn't use it because they didn't want the weight of a cocking system
the hispano on british planes were cocked before takeoff by ground crew.

a cocking system, like a tail wheel lock was unnecessary weight.

Also, I recall there being a thermodynamic update of the engines and their cooling systems. Is this still in development, or just planned?

Thx

Engine limits are always a fun discussion I always like to point to this article on that subject:

for example this...
MK 108 vs spitfire.
Some ppl will argue that single 30mm isn't enough to knock out plane, mayby in 1% cases hit in wing tip, anywhere else it is over.

I dont know where this 5minute total use of wep limit was found.
For example British version of mustang was cleared for 80" MP, so 74/75" or 80" was simply choice in engine life time not imminent engine fail in flight.
