For 109 E-3 emergency power 1.45 Ata ( 1.4 Ata for 601A) was allowed only for 1 mminut so it was very short time to use, also 1.35 Ata was also only allowed for 5 mintues - so its mean that both 1.45 Ata and 1.35 in 109 was seriously restricted by time - much more then in Merlin. Of course it was only for low to medium alts. At higher alts such boost pressure wasnt possible to achive due to lack of supercharger power.

All i'm saying is that it's not IL2:1946 anymore where we can run with 110%+WEP by opening radiators every 5 minutes and lowering prop pitch because the overheat is directly tied to RPM. In the new sim there are limits and as such, WEP really means emergency power and can't be used all day long like it was in IL2:1946.

Sure, 12lb boost could save your virtual life a few times. It's just not something you can run for the entire mission if you fly at full difficulty and that's good, because that's the way it worked in reality as well.

I would still like it to get fixed and accurate according to historical data, i just don't expect any massive advantage for being able to run it for a couple of minutes during a 60 minute sortie.

We tried hard in TW to run this same policy with WEP as well, but the DM did not have the fidelity at that time to pull it off. If you can get the engines to overheat in "required" time periods, if the cooling behaves as you would need I still think this is a viable option to restricting overuse. Although 'not' strictly realistic, it would still be a good way (best way?) to enforce realism in the use of WEP/Overboost.

Historically a lot of these limits were not strictly set because of blowing a motor, or overheating ie. within 1 or 5 mins. Most of the time engine life was also a serious consideration factored into these time limits. So, if you could track a CoD pilots time in the air, in all his flights in that plane type, over how ever long he survives in that plane, then you could really trigger a 'realistic' blown engine from the 'consistent' over use of WEP.

IMHO the direct link to heating would be a good/simple way to enforce the time limits short of anything better, but it's not strictly realistic.....



On a side note the below may be of interest on this topic of over boost:

Allisons in P40s were very resilient to over use and abuse of over boost, RAAF pilots did it routinely and they did not seem to suffer from this practice.
