How is the Yak/Lagg more durable than the P-47?

FOD? I assume debris, right?

I don't know but there is an inter-cooler and a super-charger between the turbo and the engine. The connecting ducts are long too so... doubtful but could happen.

It stands to reason that exploding cannon shells or a damaged turbo spinning apart might introduce small amounts of metal into the engine air supply, with rapidly-deteriorating results.

VAG TDI turbo unit is right next to the engine

 

P-47's Turbo is on the ass-end of the aircraft.

Yes by the belly rear gunner station.

Another difference is the R-2800 has 18 cylinders instead of just 4. One damaged shouldn't seize the whole engine.

Perhaps unreasonable could conduct another empirical test... I haven’t seen many situations where only the turbo is damaged and then the engine seizes. 

 

With a gunner station and a running P-47 on the ground, I figure shooting the aft-fuselage from a perpendicular angle to ensure the engine receives no fire should be a way to isolate turbo damage and see what happens.

unreasonable is not experienced in doing firing tests vs particular parts, nor really patient enough, but fortunately there are other players who know how to do these well.   I prefer to focus on setting up tests in the ME that resemble operational conditions,  in which we can vary one thing at a time - such as AI levels or plane type - and see the variation in overall results.

The old Il-2 had a debug mode that would show bullet impact points. Does this one have something similar? 

 

I wonder if the "aft hits" it could be either an intercooler failure or hits on the oil cooler? The intercooler is in the region of the turbo, and depending on how damage to that is modelled, it might cause a spike in manifold temperature at the engine leading to failure? 

 

Another possibility is, if you get raked from underneath, it could be that you're catching hits in the oil cooler in the chin, and that that is what's doing in the engine.
