Remove WEP limitation from the P-38L

[BnZs]

IL 2 is wrong. All P-38L models, beginning with the P-38L-1-Lo, were fitted with the Allison V-1710-F30. The preceding P-38J models, from the P-38J-1-Lo were equipped with the Allison V-1710-F17. The V-1710-F17 was rated at 1600HP at WEP, where as the V-1710-F30 was rated at 1725HP at WEP, for a difference of 125HP per engine, or 250HP per plane. The P-38J was rated at 421MPH at WEP, with 250HP less than the P-38L. It would be odd to say the least that a nearly identical plane with a very small increase in weight and a 250HP increase would be as slow or slower.

As a side note, in 1943, Allison developed the V-1710-G6 series engines. These engines were rated at 1725HP at military power with a two speed two stage supercharger and 2250HP at WEP with 100" of boost on water/methanol injection and 115/145 fuel. That was without the benefit of a turbocharger.

That AHII chart, by the way, is a chart for planes in a game, where as the discussion was about real aircraft.

Apparently the "WEP" setting for the P-38L in AHII actually reflect military power. Therefore, I propose the P-38L be allowed to run at its current "WEP" setting (really military) continuously, as is the case with all other plane's military power settings in-game.

I think this is a game concession thing because if the engines were run at FMP for five minutes it was risking engine fires and wrecked turbo-superchargers.

I think it's limited in the game to the standard limitations. When you hear about 1700hp you have field-modified and non-standard engine ratings being used. It was rampant with certain groups, and seems to have been done regularly on the P-38s.

AH models the "standard" not the "souped up hotrod", so that's probably why we have this limitation.

P.S. Our P-38 J/L make about 420mph already on WEP. Just for reference to the quote above.

The point is that Ls are running around at what amounts to their "mil" power settings. Not asking for any extra boost, just seems only fair they be allowed to do it continuously, like every other plane in the game.

You want the P-38L to adopt the military rating of an engine that it did not use?  

As for WEP, 1725HP @ 3200 rpm was Allison's rating but that was not authorized for service use.  That's why the flight manual lists WEP at 1600 hp @ 3000 rpm and why it is that way in the game.

hey, why not give them unlimited WEP, but if WEP is on for more then 5 minutes, both engines catch fire and explode! that would be a compromise!

I will get my timer.

The 1725HP rating on the -30 Allison in the P-38L is NOT a field modification. It was tuned and rated for that power at the factory. The USAAC detuned it to the same power level as the -17 engine in the P-38J.

As I explained in the thread the quote was taken from. Allison and Lockheed tested and cleared the -30 at full power, but the USAAC did not.

It is not just an increase in RPM that yields the 125HP, it is mostly an increase in boost, the increase in RPM was just a minor factor.

I hadn't read the other thread but clearly your original quote in this thread has been misread.  Your "side note" was somehow transposed to mean that engine or power setting is what should be on the P-38L when you said nothing of the sort.

On the WEP, I wasn't implying anything about RPM, I only listed RPM because I wanted to differentiate them but I didn't want to look up the MP ratings.  Although I'd bet that the main purpose of the RPM increase was to achieve the higher boost and that without the higher RPM that ultra high MP would be unattainable.

[Guppy35]

The 38s we have are just fine.  Now about that 38H?

[Raptor]

As Savage already talked about, the P38L engines came off the factory line at higher  performance levels than the USAAC let them keep. So after the USAAC lowered their performance, lockheed sent reps out and showed mechanics how to get the original power back.

[Anaxogoras]

FYI, this started over the fact that Il-2 has two P-38Ls.  One that's like ours, and one called "P-38L late" that has a significantly better max TAS, and which also climbs and turns faster than the standard P-38L.  It sounds to me like both sims are correct.

This begs the question.
Why would they reduce it to a lessor rating?

Just curious as to the logic the military had for this

Why would they remove the turbo from the P-39?
