Fully opening the throttle at sea level static would give about +17 psi boost. This would be very bad for the engine.

The Merlin III was allowed the use of 16lb boost on the Sea Hurricane IB, so I doubt that 17lb boost would be instantly fatal with 100 octane fuel, but with 87 octane bad things would happen.

You mean just like he said? He never mentioned 100 octane fuel, he is specifically referring to 87 octane fuel in that scenario. Why is it that whenever anyone mentions a Merlin engine could blow up you have to jump in to save the day and explain to all us mere mortals why the Merlin was perfect.
