The 51B

[Kenne]

No, that is a Rolls-Royce number series.

and the 1650-3 is eqivalent to the Merlin 60 series. 

[MiloMorai]

What do you mean, "where"?

P-51A is right there.  P-51C is a P-51B built in Dallas instead of Inglewood, CA.

And, the P-51K is a P-51D built in Dallas instead of Inglewood, CA.

I am not as familiar with the Packard Merlins, but I know that they don't match exactly.  The Merlin 266 is the Packard version of the Rolls-Royce Merlin 66, but the critical altitudes are 1000ft higher for the 266 than the 66.

also B models can run away 3mp faster at alt.

DUH!

My point is that his statement that the P-51B uses a Merlin 61 and the P-51D uses Merlin 66 was flat wrong.  Even your initial statement that they were 60 series was wrong.

N0 why hasnt it been introduced to Ah yet.

[Krusty]

You can go find it under "P-51D" in the hangar.

Omg really,i asked Why hasnt 51A and C been introduced.

[Karnak]

P-51A has not been introduced, just as many other aircraft have not, due to other priorities.

P-51B is the same as P-51C, just built in different locations.

That cant be right.



P-51C



Packard Merlin,V-1650-7,1,490 hp,Two stage supercharged






P-51B

Packard Merlin V-1650-3/7,1380 hp.or 1,420hp Two stage supercharged.

All in total they travel almost same speed but.Just would be nice to intro all 51's to AH.

[Squire]

1420 hp to 1490 hp is .05 of 1 percent difference.

Sometimes engines are listed as different hp even though they are the same engine as in the case of the sources for the V-1650-7 that you listed. The B/C Mustang was the same a/c. One was built in Dallas and one was built in Inglewood, as the previous poster indicated. For all intent and purpose they were the same a/c.

[Karnak]

You can find either with either engine as I understand it.  The only difference is point of manufacture.

[smoe]

Gotta remember that engine hp is a loose term. Even auto engine hp in the 60's could vary considerably depending who did the calcs.

[Guppy35]

It's amazing to me that folks want to come in and argue with things that just aren't that hard to confirm though a little research of their own.   The recent batch of P51B vs P51C threads being a good indicator.

P51B-Inglewood,California.  P51C-Dallas,Texas. 

Heaven help you guys when you get around to the folks who manufactured Corsairs under license, or any of the other birds that were built by different companies.  Give me a TBF!  We only have the TBM!    Where's my FG1-D! We only have the F4U1-D!  I want a Vega built B17!  Ours is Boeing!

It's enough to make ya weep.
