Manoeuvrability Spitifre XII ,( clipped wing).
The general manoeuvrability for dog-fighting is slightly limited by the fact that the engine cuts under negative acceleration forces. http://www.spitfireperformance.com/spit12afdu.html
The Griffon III engine has two speed manually operated superchargers, giving full throttle heights at about 6,000 feet and 18,000 feet. It is fitted with a standard Claudel Hobsen carburettor and cuts fairly easily under negative acceleration forces.http://www.historyofwar.org/articles/weapons_spitfire_mkVII.html
The Mk VII remained in production from August 1942 until early in 1944
One can see why the MK 9 was the most popular version.
