Are you sure you aren't referring to normal and military power with those ratings?

Yes, I'm sure. The reference I have that is most handy right now is "Lockheed P-38 Lightning" by Steve Pace. Refer to pages 50 and 51. It is not terribly well written, you have to read the section from P-38F to P-38H carefully, a couple of times, to pick it out, it isn't a chart.  But it does give Military and WEP, not normal and Military. I don't have anything else terribly handy right now. Of course, you have to factor in that with the pre J models, WEP was very short duration.

Pyro, I take it the "rework" of the P-38L is the "3D model" for graphics, and not the flight model. Is that correct?

At last we get a 2nd and 3rd model i won't complain.

The G is very close to the F so it's usable in early scenarios.

This also counts for the J wich is very usable in scenario's . Imagine a high alt escort misssion and u get bounced by LW planes The fights at least won't get to deck imidiatly and more high alt fight will occur. It will be challenging.

They both are only more challenging than the L offcourse The L is just the best.

At last we gonna see some green P38's flying

I'm gonna watch for scenarios and ct setups after they are released.


Ill give it a new chance :)

So

:aok  we got more types than the mustang after the next release and when my country has the numbers there will be an another P38 available

no more underdog feeling

Thanks !!

I looked at the area you cited and I think I see what you're referring to, but that's pretty ambiguous and doesn't really give much info.  What are the other sources you're referring to?

It's a confusing issue because the engine ratings were getting tweaked in the early 38's.  Allison did not put forth War Emergency Ratings on the 38's until the P-38H.  1325 HP (47.5" 3000 RPM) was the spec military rating of the P-38F.  This was derated to 1150 HP (41.5" 3000 RPM) in Mar 42 as the first 38F's were being delivered.  In Oct 42, the 1325 HP rating was reinstated for Takeoff to 4000' and a military rating of 1240 HP(45" 3000 RPM?) from 4000' to 25000'.  8th FC was testing and adopting their own standards as well which makes it even more convoluted.  Then when the 38H came out with a new engine installation, it too was derated from its spec.  So when comparing one model's power to another, it requires quite a bit of specifity to know exactly what it is that the author is referring to.

Pyro,
Is there any particular reason you are using 8th AF FC specs and standards? It should be pretty obvious that the 8th AF screwed the pooch with the P-38. Why not look at units with a much higher success rate?

Use the stuff those guys in the MTO were using who were flying Fs and Gs well into the spring of 44 :)

They knew what they were doing

Could we use the 2000hp Fw190D-9 then?

He asked for your references. You will need more then the "Mr. P38 pilot said..." line that is always the main part of your argument.

Post credible documents or data and I am sure Pyro will look at them.

You cited Lockheed P-38 Lightning by Steve Pace and Pyro read the pages and doesn't see what it is you 'interpreted after you re-read it several times'. As if your lack of objectivity would allow any other interpretation.

As Kweassa said there's all types of this sort information floating about for every aircraft in AH. You don't model planes based on some poorly written section of a book or because based on the memory of 80 year old men. You need real data.

Here's a website I found with more info on varients:

http://p-38online.com

P38G: new Allison V-1710-F-10 engines; At 24,000 ft. it produced 1,150 hp, and at 27,000 ft., it produced 1,100 hp; It also incorporated the newly designed B-13 superchargers; Late 'G' production models were capable of carrying two 2,000 lb. bombs.

P-38J: V-1710-F-15 engine could produce 1,600 hp. The top speed was 425-430 mph at 30,000 ft., and 406 mph at 20,000 ft.; The leading edge intercoolers were removed, and extra fuel tanks (110 gallons) were installed.; It also had electrical operated dive brakes, and an aileron boost system. This boost system enabled the pilot to only exert 17% of the previous force to control the yoke.

P-38L: V-1710-F30 engine produced 1,600 hp at maximum power, and produced a normal rating of 1,100 at 30,000 ft.; External fuel capacity was increased to allow two 300-gallon tanks to be used; One interesting improvement was the installation of a new tail-warning radar system. It would signal the pilot through flashing lights and bell sounds when an aircraft was in close proximity behind the aircraft. ; Maximum speed at 25,000 ft. was 414 mph,
and could reach 20,000 ft. with a takeoff weight of 17,500 in seven minutes. The P-38 L was the final air superiority/strike variant of the P-38 produced.

:confused:  I don't know what you mean by that.  Where did I say or even imply that I was using 8th FC specs?

I think the 8th FC data he is refering to is the 414mph top speed of the P-38L.  CVH has several times stated that the 414mph speed was it's top speed on MIL power and the P-38L's top speed on WEP was, IIRC, about 440 or 450mph.

I was looking at your post where you said the "8th FC was testing and adopting their own standards as well which makes it even more convoluted."

Gave me the impression you were looking at their Bravo Sierra as if it were reliable and accurate data, which it is not.
