Martlet WIP Video in General Discussion Posted May 14 On 5/4/2019 at 7:47 PM, -=PHX=-SuperEtendard said: If i'm correct the Martlet (the P-40s for sure) didn't have manifold pressure regulators, so how would the different engine regimes work in game? For example the early P-40E was cleared for 5 minutes at 42" (which is the setting in IL-2 Battle of Moscow), and later in the war was cleared for 5 minutes at 57". However since the engine wasn't regulated nothing stops the pilot from using much higher power levels (60" or more even). In IL-2 GB the engine dies when you exceed the manual spec after a short amount of time, which isn't mechanically realistic. IRL the engine would tolerate this abuse though it would have it's lifespan severly limited the more time it is run hard. How would this work in CloD? The P-40/Martlet engines would run as high as they can even though it's vastly above their official specifications (as long as detonation parameters aren't met) without damage, or will there be some mechanic to limit their use? Since we get a new plane everytime players aren't worried about engine lifespan or having to deal with the crew chief for going through engine replacements much quicker than they have supplies of them. Aircraft engines will be limited to the boost levels which were used in the time period of the particular module being replicated. So for example, the V-1710-33 which equipped the Tomahawk IIA/IIB, (P-40C) will come in two versions, one limited to the boost for the period June '41 to December '41, the other for early 1942. The V-1710-39 which equipped the Kittyhawk IA, (P-40D/E) will come in one version... for the period of early 1942. (when it first saw service in the Desert) Yes, the pilot could actually adjust the allowable boost on the Allison themselves, but in most circumstances the adjustment was wired to limit maximum boost to what was recommended by the mechanics for the time period. The process was a learning experience for the ground crews.... it took time to determine how much abuse the Allison could tolerate... in fact it was an extremely robust engine... probably tougher than a Merlin. By the end of 1942, some Squadrons were running 66-70 inHG in the early V-1710 versions with the smaller supercharger impellers.
