| Shame they didn't put a Merlin 61 in like the Mustang, it might have had the same effect! I agree with the Hurricane statement.
Have you heard of the P40Q looks nothing like the original but had a max speed of 423mph! |

most radials, especailly the R-2800, were too big for the P-40..........

Country: | yes but as a bigger engine was fitted, you'd need more fuel, possibly a larger wingspan, and the airframe would need considderable "beefing up" to take the stress..........

The only thing the Merlin really had going for it over the Allison was that RR had designed a supercharger stage to fit between the valve bays. This meant that only one stage had to be fitted externally, so it lead to a more compact design. It was harder to maintain though because of this compactness.
The Allison was smoother running and developmed just as much power for weight for a given level of boost as the Merlin. | |

Country: | The Allison was also a bit more robust than the Merlin, was able to be over boosted and over reved. |
