FlyingShark 156 Posted October 3 Hi, On the P51 you can put the supercharger from automatic mode to manual and back. However, when in manual, it only stays in "Low" position, I don't seem to be able to put it in "high" position. Is it maybe that way or am I doing something wrong? Have a nice day.

CSW_Hot_Dog 35 Posted October 3 You can not switch to second position in manual mode in game. IMHO, it is wrongly modelled. Share this post Link to post Share on other sites
Talon_ 1257 Posted October 3 On 150 octane fuel it should be manual like the Spitfire. 1 Share this post Link to post Share on other sites

It is a current limitation, we should have the three options available (manual 1st gear, auto, manual 2nd gear) but currently the game supports either both manual gears, or first gear manual and auto. In the future they might be able to implement the possibility of having these 3 modes selectable. Edited October 3 by -=PHX=-SuperEtendard Share this post Link to post Share on other sites

FlyingShark 156 Posted October 4 Thanks for the replies, guys. I hope they give us control over it in the future. As it's now, I find it a bit useless to switch to manual mode and then not being able to switch to the gear you want. Have a nice day. Share this post Link to post Share on other sites
Jansgi 7 Posted October 4 (edited) It is correct as it is. Quote The LOW position on the switch on the instrument panel makes it possible to operate the supercharger in low blower mode at high altitudes. This provides better range at high altitudes, which can be used for long-range flights. The HIGH position on the switch makes it possible to test the high blower mode on the ground. The switch must be held in the HIGH position by hand, however, because it is springloaded and returns to the LOW position when released.

I remember reading that they just reset the aneroid controlling the gear shifting point. Edited October 4 by Jansgi Share this post Link to post Share on other sites

The Mustang autoshifts at the best point for 100 octane fuel even when running on 150 in-game. Share this post Link to post Share on other sites

I can't find the book so when I said I know for a fact can be an overstatement until I can provide the source. For now I only have 150 grade fuel tests which in no means is proof. http://www.wwiiaircraftperformance.org/150grade/150-grade-fuel.html The aneroid controlling supercharger shifting point was reset at the begining of the test to shift from low to high blower at sixty-two inches Hg. in a war emergency climb.

BM357_TinMan 108 Posted October 4 (edited) I'm only speaking from what I think might be true so, take it for what it's worth but: I think the way it works in reality is, you can set it to "first" or "automatic". You can engage the second stage but you have to hold it there if you want to engage the second stage manually. edit - and it looks like someone already posted this answer in a post above.....

Not entirely true, you can use it while flying high with low manifold pressure setting. Automatic give you optimal switch only on full power setting, but lower MAP gives you higher optimal switch altitude. Same as on 18 lb/sqinch spitfire IX.

None of the P-51 manuals I've seen say it was manually controlled with 150 octane, including one that is dated around August 1945. 1 Share this post Link to post Share on other sites
