A noob's questions about the K4

[vadupleix7]

Hello, 

I'm pretty new to the WWII fighter stuff and just began to sink into the game as K4 came out. I have a couple questions about its engine, which may sound dumb, but I'm still learning.

1. How much of the improvement is there when comparing the DC to DB engine? From people's words it seems DC at 1.98ata is really a big deal but when checking the stats in game, the DC variants actually has worse turn and climb performance than the DB variant (marginally worse but still, shouldn't it be the other way around?), so I wonder what power setting those stats are built upon? 

2. I remember seeing one of the K4 tutorial for the other game (with 1.8ata DB engine I believe) which mentioned that the MW50 will only kick in at full throttle (which is the case for our K4 as well) and if you go above 1.42ata (1.4-ish) but don't go full throttle you will damage your engine, is that the case or is there any intermediate power setting?

3. A general question, a google search gives many explanation about the relationship between rpm and manifold pressure and how they are not the same, but what about manifold pressure vs thrust produced? Do they have a linear relationship (or any deterministic relationship) regardless of altitude/weather condition? 

Sorry if the questions are silly but a brief google search didn't give me enough clue.

Thanks!

Regarding your 2nd question.

 

If you go above 1.42ata in the other sim your ata will suddenly rise all the way up to 1.8ata (WEP on the last 5% of throttle range)

If you forget to activate MW50 you will damage the engine. 

 

In IL-2 I think it is implemented differently as MW50 is activated automatically when going full throttle.

Thanks! That makes sense.

So regarding the usage, we have 10 min max for 1.98ata and 30 min for 1.42ata (combat power, correct me if I'm wrong), then what about the intermediate settings like 1.8ata? Do I get a longer "permissible using time" than 10 min  or shall I treat that like WEP as well?  (I fried my engine so often during my first couple fights in this game so I'm becoming a bit paranoid about it)

Also I have the habit of "resting" my engine after a couple minutes of usage in WEP by going back to 1.42ata, so say I have used 5 min of WEP and then I go back to combat power, will that "recharge" the 10min WEP timer or not? All sources mentioned about this "recharging" by going back to continuous power so I suppose combat power is not counted?

In BoX you will damage your engine quickly if you're in emergency power with low mw50 pressure, eg 100% throttle is fine for 10mins, but 90% will damage your engine in a minute or two.
