Check if coil booster wasn't depressed during flight, some times they got stuck in push in position, same with starter buttons.

If maker of the plane states that engine can operate at 64" at 2700rpm for 5 min, and engine brakes before 5 min mark, i think some heads would be chopped off if it would happen. My pinion is that engine modeling is too sensitive, engine limits are set for respected engine life time, let assume that P-47's engine had to live for 100h, if engine seized up after 30 min of flight , something is way wrong.

I will add that even from damage plane you can recover undamaged parts, ejection system is not 100% safe too, if you can land you should land, in addition unmanned jet in the middle of task group is not a good idea. And if you can fly back your f/a-18 to carrier, the damage can't be fatal, am i right ?

@Tuturuu You need to separate this topics. 1. MAP gain from speed is due to ram effect and has nothing to do with turbocharger or engine it self, engine inlet is faced forward so faster you fly the higher air pressure enters the plane. 2. MAP changes with alt due to turbocharger regulator unit. Ambient pressure changes with alt it affect whole system as well. Axis planes has boost regulator which maintains set MAP withing regulating range, constant speed unit has nothing to do with it. Constant speed prop unit job is to maintain steady rpm through the flight so engine can operate at optimal rpm regardless of speed of the plane. Only difference in axis planes is that rpm lever is build in to throttle. P-47 does not have boost regulator like 109 or p-51 this is why we experience this MAP behavior.

@Mud exactly

I found this very interesting so i posting it here.

What rpm settings are you using, try low rpm. Did they mentioned what power settings were used for this 240mph night cruise ? try 2000 rpm or 1800 rpm

It is in MISC tab.

@peachmonkey yes it is. Access only from main menu options tab, general tab but i cant remember exactly.

No need to use oil dilution it does not work at that moment, i use mixture lever auto-rich bind as well i have no problem with that. I switch generator ON before start up. When you spawn aircraft on the ground, controls axis are not synced when sync option is off, so you have to move your hardware axis to sync them. If your rpm lever is full aft on your hardware, and you spawn plane, rpm lever in game will not be full aft, there is option in game to force hotas sync. This is only thing which comes to my mind.

Cooling bug is with spitfire since release so, i would say that this is high on priority list, but who knows.

I did test fly yesterday and i noticed no anomalies, everything works as expected. P-47 uses electric constant speed prop, and rpm range is between 1600 to 2700. RPM lever set this rpm limiter for the engine through prop governing unit, when lever is full aft it set rpm limiter to 1600rpm, so as long engine rpm are below 1600, governing unit is not activated, prop pitch is full fine, as soon engine rpm reach 1600rpm governing unit will increase prop pitch and by this it will prevent rpm to go any higher then 1600, more throttle you add, pitch of the prop will increase accordingly to hold 1600rpm. Manual says pilot to set rpm lever full forward for safety reasons to makes sure that prop rpm is set to max before take off, so on the ground this lever must be at full on position every time, after you land, set rpm to max, cockpit check list prop lever full on etc etc, at every step forces pilot to check it, taking off at full aft position would end up in disaster probably.

I use warthog throttle, there is a speed brake switch which has hardware toggle behavior, when i move that switch forward it locks in to position so i don't need to hold it, that's it

What do you mean by "propeller fail to start" ? This switch on Curtis electric propeller panel allow to control pitch directly so you can manually adjust rpm, but in this mode engine rpm will not be governed. You definitely can start and taxi with prop lever full aft, but take off i'm not sure. Are you sure that prop switch was in auto position not in fixed pitch mode ? If you touch this switch it will drop to fixed pitch mode, you have to flip it up to go to auto constant speed mode. In auto mode and rpm full back prop governor will maintain very low rpm something like 1700 or even lower, at this setting take off will take a lot of run way if even possible, but when switch was moved in to fixed pitch mode you would take off with no problem. BTW on the ground rpm lever position does not make any difference while taxing or warming up engine or starting up engine, this lever determine target rpm for governor, if engine's rpm are below governor range, let say that governing range is 1700-2700 in P-47, lever position change nothing while engine rpm are below 1700 which are on the ground, you warms up engine at 1200rpm and taxing at around 1000 rpm.

Check in game bindings.

Just out of curiosity, @Art-J have you ever flown plane in game mode in DCS, i have never did that my self. All i know about game mode that some weird behaviors may happen that's it, i know this only from posts on this forum. I also heard that ED considered to remove this game mode completely, but based on ongoing stuck of bugs, ED team does not have spare resources to do that I assume.

Hard to tell, but P-47 manual tells pilot to not draw more then 52" on take off, but apparently in DCS you can't do tat 52 is about max you can have for take off, manual mention something about take off stop on throttle quadrant.

Look at turbo rpm, when you climb up it spools up so this boost comes from turbo, once turbo kick in it can maintain boost at lower alt.

@GunfreakIf you control throttle and boost separately, you can achieve maximum performance out of P-47, by using single axis so throttle and boost lever interconnected you sacrifice some power for easier engine operation, no matter way you use you still experience turbocharger kick in behavior.

There are couple things about P-47 which make it totally new experience then spitfire or p-51. First thing already mentioned, P-47 has no boost regulator, so speed and altitude change will affect your MP. Second thing is P-47's engine is supercharged and turbocharged. Throttle control butterfly valve at supercharger intake, and boost lever control how much exhaust gases goes to turbine via turbo regulator unit. You can link throttle and boost lever but i recommend to unlink them. turbocharger rpm unlike supercharger rpm depends on exhaust gases flow through turbine, so when turbocharger starts to boost it create chain reaction, higher boost more exhaust gases then turbo rpm goes even higher and so on so on, so when turbo kicks in be ready to retard throttle, this the reason why you are experiencing this sudden boost spikes.

You can run engine at 2700 up to 52inch for very long time, just watch oil temp from my experience cooler needs to be wide open, after take off it give impression that neutral position is ok bu it will creep above 100c if you do nothing. Anyway engine is too fragile still, if you over rev the engine it dies even if max diving rpm are not exceeded so as i feel it engine in P-47 wasn't tweaked for very long time.

After you are strapped, there is no way to reach door. So in case mosquito, when crew is ready to start, door is closed.

Not gonna happen, gun convergence and harmonization is set per manuals.
