Engine choices for P-51 mustang ?

Unfortunately, the 1800 HP power for a service-worthy HS 12Z was probably a sales pitch, 1500 HP was the max power. Please see the post #250 here.

I had noted that and a correction of the weight on the Russian HS derivative but presented the chart purely using the information that Shortround used in his post.

I see that the H-S 12Z-15 and 12Z-16 used in the Arsenal VB.10 are each listed as 1,150hp each and the 12Z-17 (which the -15 and -16 are derived from) used in the Ikarus S-49 was rated at 1,480hp.
