A.P. 129 RAF Flying Training Manual, Part I - Landplanes

Once again you forgot atmospheric pressure in your calculation.

OOPS. Of course the British have to be different. Not any better, just different from everyone else in the world.

MAP - Manifold Absolute Pressure and it does not mean Manifold AIR pressure.

Good, I was thinking 1.6 is pushing it for the odds of somebody attempting it and surviving.

1.2 makes his story more credible, still very lucky but definately more credible that he was able to push it to +16lbs momentarily on 87 Octane.
