It combined features of the Mk XI with the Griffon engine of the Mk XIV. After the first 25 (type 389s) were produced, later aircraft were also fitted with the pressurised cabin of the Mk X and the fuel capacity was increased to 256 gallons, three-and-a-half times that of the original Spitfire This version was the type 390.

Depending on the supercharger fitted, engines were rated as low altitude (e.g.; Merlin 66, Griffon III), where the engine produced its maximum power below about 10,000 feet (3,000 m), medium altitude (Merlin 45), where the engine produced its maximum power up to about 20,000 feet (6,100 m), and high altitude (Merlin 70), where the engine produced its maximum power above about 25,000 feet ...
The performance increase was described by Jeffrey Quill as a "quantum leap" over that of the Mk Vb and another Spitfire airframe, R6700 was modified to take the new engine. Although design work on the Mk VII and VIII series was under way, these would take over a year to get into production and a counter to the Fw 190 was urgently needed.
Although these "clipped-wing" aircraft are popularly known as "LF" versions due to the fact that they were designated "LF" (i.e. Spitfire LF Mk V), the "L" actually refers to the different versions of the Rolls-Royce Merlin engines used, which were optimised for low-altitude performance with "cropped" supercharger impellers (Merlin 45M, 50M or ...
Early versions of the Spitfire Mk 26 used an eight-cylinder 180 hp (134 kW) Jabiru 5100 horizontally opposed aero engine, but early installations suffered from inadequate cooling. The company now offers a V6 engine. The normally aspirated version of this engine produces 226 hp (169 kW) with a supercharged version producing up to 310 hp (231 kW).
The Spitfire was much slower at such a low level; the prototype was only capable of 290 mph (470 km/h) at this height. [1] Consequently, a record-breaking machine would have to be extensively modified. Rolls-Royce began work on a sprint version of the Spitfire's Merlin engine, to run on a special fuel mix. [1]

The Spitfire engines were Poly variants of Chrysler's FirePower (Hemi) engine. Chrysler built three Spitfire engines: the 331 Poly, 354 Poly, and the all-new 301 Poly, which did not have a Hemi version. They were introduced for 1955 in the low-priced Chrysler Saratoga and Windsor models and were used through 1958. All Chrysler Spitfire engines ...
