If using quotes to backup your agenda at least make sure the plane in question is a Spitfire. The cooling system on a Wellington II was very different than that of a Spitfire Mk I, Hurricane, Defiant or any other plane with a Merlin. Finding one quote stating a Merlin could run at +10 lb boost for five hours does not mean they ALL could. Adequate cooling in the early Spitfires was a problem that was not overcome until the extra radiator was introduced on the Mk IX. Even then the issue wasn't totally cured. The problem was not so severe in the Hurricane because its radiator was directly in the prop wash. Have a read of this, this is taken from the chief pilot of the BBMF. They fly both Hurricanes and Spitfire as well as a Lancaster bomber.

Note the very large radiators directly under each ungine for the Mk II Wellington.
