If I understand correctly...
- The P-40F's and L's received the Packard Merlin 28 (Mark XX) [V-1650-1] (single stage, two speed supercharger)
- The P-51 received the V-1650-3 (two speed, two stage supercharger)
Questions:
1) Why use the V-1650-1 in the P-40? What was the expected benefit over the V-1710?
2) Why not use the V-1650-3 in the P-40? With all the altitude criticism the P-40 received, why not give it the V-1650-3?
