I am puzzled why the MIL speed of the Mossie is different at 5,000ft though.

It seems the old Mossie did gain TAS faster at increasing altitudes than the new one. It also looks like that the new model's supercharger's first stage has a higher FTH than the old ones.

I'll need to do more tests, but my charts in books put the Merlin 25's FTH at 13,000ft, which is why I tested it there.  Got higher speeds even though boost wasn't hitting +18lbs once I got over 12,000ft.  Boost in the old Mossie was almost entirely disassociated from actual performance, so I ignore it.

Also note that the new Mossie's MIL starts out the same, well, 1mph slower, and ends up slightly faster.  The dip at 5,000ft is a dip.

Does anyone have handy the weight of the old Mossi as tested for speed/climb?  The new model is lighter... but I cant find the exact figure for teh old model.  I've misplaced that sticky note.   :)

 If you check Boozeman's post he listes the weights old and new! :aok

But is that the weight at what the old Mossi was rated for the speed/climb charts?  I am under the impression that Boozeman's data is controlled for his testing.

I have the old chart saved at home.  I can answer when I get home, but that will be about five hours from now.

The old speed/climb charts do not show the weights, at least the one I have printed off from the trainer's website.

I also have a copy of AH 2.18.8 that I have been using for testing purposes.  I can get you any weight you like, just tell me the configuration.

I recall the original charts were at 22,221lbs, 100% fuel and 2,000lbs of bombs.

The Mossie has a positive K/D ratio for the first time that I have ever seen:

Mosquito Mk VI:    Kills: 2051    Deaths: 1904     Kill/Death Ratio: 1.08

... missions were to be met by the commitment of alerted swarms of fighters, composed of Me 109's and Fw 190's, that were strategically based to protect industrial installations. The inferior capabilities of these fighters against the Mosquitoes made this a hopeless and uneconomical effort. 1.JD KTB

Actually, it's not just a dip at 5000 ft. The difference is there form SL all the way up to 12 kft. The gap is widest at 8.5k, then gets narrower and at 12-13 k the speeds are almost identical.   
North of 13k the gap widens again, and at 15k there is again a clear advantage of almost 20 mph for the old Mossie. Unfortunatly the new graphs do not go above 15k, it would be interesting to see how the performance is at higher altitudes.

The new model is lighter indeed, but those 800 lbs will only make a minor difference on an 18000 lbs aircraft.
Actually, on MIL the climbrates have decreased by about 10%, on WEP they got a tiny bit better. This will vary at different altitudes though.

Boozeman, at sea level the difference is 1mph.  At 5,000ft it is 13mph.  At 12,000ft it is 4mph in favor of the new one.  At 13,000ft it is 2mph in favor of the new one.
