Dowding states that the the EBCO allows for 12lb boost for 5mins. I know you love the RR Merlin but would you really have us believe that this could be done with 87 octane fuel?

THAT IS WHY YOU HAVE PILOT ANECDOTES OF FLYING AT +16 LBS ON 87 OCTANE! If they tested the engine to 10.5lbs then a low engineering safety factor of 1.6 yields 16.8lbs. That pilot who did that was extremely lucky his engine did not destroy itself from detonation. Quote:

10.5lbs (+ 15.0) is 100% 16.0lbs (+ 15.0) is 121,56% This is only a factor of 1.2; a factor of 1.6 would be +25.8lbs (+ 15.0). Quote:

![]() I just can't believe that anyone could post something like this...even Kurfurst can't possibly agree with this! The Me109e was limited to ~6lb boost with 87 octane fuel, and even late war with 100 octane the 109 could never pull more than ~12lb boost (even Kurfurst only claims ~14lbs), yet RAF fanboy Crumpp believes that the RR Merlin was so superior, in 1940, that it could pull 16lb boost with 87 octane fuel no less! And if it could pull 16lb boost with 87 octane and escape destruction, then 12lb boost would be no problem... ![]() Next Crump will be asking for an 18lb mod for the 100 octane RAF fighters... ![]() Crumpp's faith in UK technology seems to know no bounds... ![]() |

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. |
