second run for a very famous boat that had 11 starts and 10 wins. Unfortunately on the 11th start it crashed and has been in mothballs for almost 4o years. Bought back to life by David Pagano and many many hours of labour
UNIQUE! Rolls Royce with Spitfire Merlin V12 engine! ANGRY SOUND!!

Rolls-Royce Merlin Engine
Considered a British icon, the Merlin was one of the most successful
aircraft engines of the World War II era, and many variants were built by
Rolls-Royce in Derby, Crewe and Glasgow,as well as by Ford of Britain at
their Trafford Park factory, near Manchester. The Packard V-1650 was a
version of the Merlin built in the United States. Production ceased in 1950
after a total of almost 150,000 engines had been delivered, the later
variants being used for airliners and military transport aircraft.
The PV-12 first ran in 1933 and, after several modifications, the first
production variants were built in 1936. The first operational aircraft to
enter service using the Merlin were the Fairey Battle, Hawker Hurricane and
Supermarine Spitfire. More Merlins were made for the four-engined Avro
Lancaster heavy bomber than for any other aircraft; however, the engine is
most closely associated with the Spitfire, starting with the Spitfire's
maiden flight in 1936. A series of rapidly applied developments, brought
about by wartime needs, markedly improved the engine's performance and
Many ascribe the victory during the Battle of Britain to the Merlin powered
Royal Air Force (RAF). And later its use in the American P-51 Mustang.

Rolls Royce Griffon V12 Mk58 36.7 litre engine run at Duxford Flying Legends

ROLLS ROYCE merlins
In 1936, the Air Ministry had a requirement for a new fighter aircraft with
airspeeds that would eventually have to be over 300 mph (480 km/h).
Fortunately, two designs had been developed entirely as private venture
exercises: the Hawker Hurricane and Supermarine Spitfire. Both were
designed around the PV-12 instead of the Kestrel, and were the only British
modern fighters to have been so developed. Production contracts for both
aircraft were let in 1936. The PV-12 was instantly catapulted to the top of
the supply chain and became the Merlin.
Early Merlins were considered to be rather unreliable, but Rolls soon
introduced a superb reliability-improvement programme to improve matters.
This consisted of taking random engines from the end of assembly line and
running them continuously at full power until they failed. Each was then
dismantled to find out which part had failed, and that part was redesigned
to be stronger. After two years of this, the Merlin had matured into one of
the most reliable aero engines in the world, and could be run at full power
for eight-hour bombing missions with no problems.
As it turned out, the Peregrine saw use in only two aircraft, the Westland
Whirlwind and the Gloster F9/37. Although the Peregrine appeared to be a
satisfactory design, it was never allowed to mature; Rolls-Royce's priority
was troubleshooting the Merlin. The Vulture was fitted to the Hawker
Tornado and Avro Manchester, but proved unreliable owing to big-end
failures caused by lubrication problems. With the Merlin itself soon
pushing into the 1,500 hp (1,100 kW) range, the Peregrine and Vulture were
both cancelled in 1943. upgrades to the Merlin were the result of
ever-increasing octane ratings in the aviation fuel available from the US,
and ever more efficient Supercharger
designs. At the start of the war the engine ran on the then-standard 87
octane aviation spirit and
The next major version was the XX which ran on 100 octane fuel. This
allowed it to be run at higher manifold pressures, which were achieved by
increasing the "Boost" from the
centrifugal type Supercharger. The
result was that the otherwise similar engine delivered 1,300 hp (970 kW).
The process continued, with later versions running on further-increased
octane ratings, delivering higher and higher power ratings. By the end of
the war the "little" engine was delivering over 1,600 hp (1,200 kW) in
common versions, and as much as 2,070 hp (1,544 kW) in the Merlin 130/131
versions used on the de Havilland Hornet. The Merlin was running on 150
Octane fuel by the time it was used in the Lancaster bomber. This high
octane rating was achieved by large quantities of lead anti-knocking agent,
so much in fact, that the engine cowlings around the Exhaust outlets were usually heavily stained
with it. It had to be regularly removed for aerodynamic, not to mention
The Merlin's lack of direct fuel injection meant that both Spitfires and
Hurricanes were, unlike the contemporary Bf-109E, unable to nose down into
a deep dive. This meant the Luftwaffe fighters could 'bunt' into a
high-power dive to escape attack, leaving the Spitfire spluttering behind
as its fuel was forced by negative 'g' out of the carburettor. RAF fighter
pilots soon learned to 'half-roll' their aircraft before diving to pursue
their opponents. The use of uninjected carburettors was calculated to give
a higher specific power output, due to the lower temperature, and hence the
greater density, of the fuel/air mixture, compared to injected systems.
"Miss Shilling's orifice" (invented in March 1941 by a female engineer
named Shilling), a holed diaphragm fitted across the float chambers, went
some way towards curing the fuel starvation in a dive. Further improvements
were introduced throughout the Merlins, with injection introduced in 1943.
