   en.wikipedia.org/wiki/Supermarine_Spitfire...

   This Spitfire has the "cropped" Merlin 45 series engine and the "clipped" wings. The British Supermarine Spitfire was one of the most popular fighter aircraft of the Second World War . The basic airframe proved to be extremely adaptable, capable of taking far more powerful engines and far greater loads than its original role as a short-range ...

   These remarkable increases in performance arose chiefly from the introduction of the Rolls-Royce Griffon engine in place of the famous Merlin of earlier variants. Rated at 2,050 hp (1,530 kW), the 12-cylinder Vee liquid-cooled Griffon 61 engine had a two-stage supercharger, giving the Spitfire the exceptional performance at high altitude that ...

   The later Spitfire Mk 26 uses the Mk 25 wings with the fuselage increased to 80% scale to provide room for a passenger seat in tandem behind the pilot. The Mk 26B has a 90% scale fuselage. The Spitfire kit has the same power-to-weight ratio as the original. [6] The aircraft was reviewed by the Australian Ultralight Federation in 2001.

   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.

6. Supermarine Spitfire (early Merlin-powered variants) - Wikipedia

   en.wikipedia.org/wiki/Supermarine_Spitfire...

   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 ...

7. Rolls-Royce Merlin alternative uses - Wikipedia

   The engine drives a General Motors TH400 automatic transmission, via the step-up gearbox devised by Dodd to allow the low-revving Merlin engine to work properly with the conventional GM transmission. Perhaps due to space constraints as well as roadworthiness considerations, the Merlin used in the Beast is non-supercharged.

   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 ...

   The modified engine was designated the "TMO" and the modified exhaust system was supplied as kit that could be installed on existing engines either by the operator or by Rolls-Royce. [ 24 ] Power ratings for the civil Merlin 600, 620, and 621-series was 1,160 hp (870 kW) continuous cruising at 23,500 feet (7,200 m), and 1,725 hp (1,286 kW) for ...
