Formula 1 Turbo Engines - The Golden Era [Full Documentary]
Formula One currently uses 1.6 litre four-stroke turbocharged 90 degree V6 reciprocating engines.
The power a Formula One engine produces is generated by operating at a very
high rotational speed, up to 15,000 revolutions per minute (RPM). This
contrasts with road car engines of a similar size which typically operate
at less than 6,000 rpm. The basic configuration of a naturally aspirated
Formula One engine had not been greatly modified since the 1967 Cosworth
DFV and the mean effective pressure had stayed at around 14 bar MEP.
Until the mid-1980s Formula One engines were limited to around 12,000 rpm
due to the traditional metal valve springs used to close the valves. The
speed required to operate the engine valves at a higher RPM called for ever
stiffer springs, which increased the power loss to drive the camshaft and
the valves to the point where the loss nearly offset the power gain through
the increase in rpm. They were replaced by pneumatic valve springs
introduced by Renault, which inherently have a rising rate (progressive
rate) that allowed them to have extremely high spring rate at larger valve
strokes without much increasing the driving power requirements at smaller
strokes, thus lowering the overall power loss. Since the 1990s, all Formula
One engine manufacturers used pneumatic valve springs with the pressurised
air allowing engines to reach speeds of nearly 20,000 rpm.
In addition to the use of pneumatic valve springs a Formula One engine's
high RPM output has been made possible due to advances in metallurgy and
design allowing lighter pistons and connecting rods to withstand the
accelerations necessary to attain such high speeds, also by narrowing the
connecting rod ends allowing for narrower main bearings. This allows for
higher RPM with less bearing-damaging heat build-up. For each stroke, the
piston goes from a null speed, to almost two times the mean speed,
(approximately 40 m/s) then back to zero. This will occur four times for
each of the four strokes in the cycle. Maximum piston acceleration occurs
at top dead center and is in the region of 95,000 m/s2, about 10,000 times
standard gravity or 10,000 g.
In 1966, with sports cars capable of outrunning Formula 1 cars thanks to
much larger and more powerful engines, the FIA increased engine capacity to
3.0 L atmospheric and 1.5 L compressed engines. Although a few
manufacturers had been clamouring for bigger engines, the transition wasn't
smooth and 1966 was a transitional year, with 2.0 L versions of the BRM and
Coventry-Climax V8 engines being used by several entrants. The appearance
of the standard-produced Cosworth DFV in 1967 made it possible for small
manufacturers to join the series with a chassis designed in-house.
Compression devices were allowed for the first time since 1960, but it
wasn't until 1977 until a company actually had the finance and interest of
building one, when Renault debuted their new Gordini V6 turbo at the British Grand Prix at Silverstone
that year. It was in 1980 that Renault proved that turbocharging was the way to go in order to stay
competitive in Formula One (particularly at high-altitude circuits like
Kyalami in South Africa and Interlagos in Brazil) ; this engine had a
considerable power advantage against the Ford-Cosworth DFV, Ferrari and
Alfa Romeo naturally aspirated engines. Following this, Ferrari introduced
their all-new turbocharged engine in
1981. Following these developments, Brabham owner Bernie Ecclestone managed
to get BMW to make the team turbocharged
inline-4 engines from 1982 onwards. And in 1983, Alfa Romeo made a turbocharged V8 engine, and in the same year and
following years, Honda, Porsche (badged as TAG), Ford-Cosworth and other
smaller companies made turbo-charged
engines, mostly twin-turbocharged V6's.
By the midpoint of 1985, every competing team had a turbocharged engine in their car. And by 1986, the
power figures were becoming quite crazy- all of the engines had
unrestricted turboBoost in qualifying, where they were
developing 1,350+ hp at 5.5 bar Boost (80 psi). These engines and gearboxes
would only last about 2-3 laps, and for the race, the turbocharger's Boost was restricted to ensure engine
reliability; but the engines still produced 950-1000 hp during the race.
Following their experiences at Indianapolis, in 1971 Lotus made a few
unsuccessful experiments with a Pratt & Whitney turbine fitted to chassis
which had also 4WD. The power range was between 390 hp (290 kW) to 500 hp
(370 kW), turbos 500 hp (370 kW) to 900
hp (670 kW) in race, in qualifying up to 1,300 hp (970 kW).

Awesome V12 Monster diesel engine Awake and Alive startup
Awesome V12 Monster diesel engine Awake and Alive startup
The first V-type engine (a 2-cylinder vee twin) was built in 1889 by
Daimler, to a design by Wilhelm Maybach. By 1903 V8 engines were being
produced for motor boat racing by the Société Antoinette to designs by
Léon Levavasseur, building on experience gained with in-line four-cylinder
engines. In 1904, the Putney Motor Works completed a new V12 marine racing
engine -- the first V12 engine produced for any purpose. Known as the
'Craig-Dörwald' engine after Putney's founding partners, the engine
mounted pairs of L-head cylinders at a 90 degree included angle on an
aluminium crankcase, using the same cylinder pairs that powered the
company's standard 2-cylinder car. A single camshaft mounted in the central
vee operated the valves directly. As in many marine engines, the camshaft
could be slid longitudinally to engage a second set of cams, giving valve
timing that reversed the engine's rotation to achieve astern propulsion.
"Starting is by pumping a charge into each cylinder and switching on the
trembler coils. A sliding camshaft gave direct reversing. The camshaft has
fluted webs and main bearings in graduated thickness from the largest at
the flywheel end." Displacing 1,119.9 cuin (18,352 cc) (bore and stroke
of 4.875" x 5" (123.8 x 127 mm)), the engine weighed 950 pounds (430 kg)
and developed 150 bhp (110 kW). Little is known of the engine's
achievements in the 40-foot hull for which it was intended, while a scheme
to use the engine to power heavy freight vehicles never came to
fruition. One V12 Dörwald marine engine was found still running in a
Hong Kong junk in the late-1960s.
Two more V12s appeared in the 1909-10 motor boat racing season. The Lamb
Boat & Engine Company of Clinton, Iowa built a 1,558.6 cuin (25,541 cc
(5.25" x 6" (133.4 x 152.4 mm)) engine for the company's 32-foot Lamb IV.
It weighed in at 2,114 pounds (959 kg). No weight is known for the massive
3,463.6 cuin (56,758 cc) (7" x 7.5" (177.8 x 190.5 mm)) F-head engine built
by the Orleans Motor Company. Output is quoted as "nearly 400 bhp (300
By 1914, when Panhard built two 2,356.2 cuin (38,611 cc) (5" x 10" (127 x
254 mm)) engines with four-valve cylinder heads the V12 was well
established in motor boat racing.
In automobiles, V12 engines have not been common due to their complexity
and cost. They are used almost exclusively in expensive sports and luxury
cars because of their power, smoother operation and distinctive sound.

BEST Formula 1 Sounds - V6, V8, V10 and V12
Over the years I had the opportunity to film many Ferrari F1s from
different eras (from the early V6 turbo
to the V10, V12 up to the most recent V8) and with this video I want to
show you a glimpse of the best sounds of these screaming engines, turn up
Ferrari Formula 1 - Loud Start-up!
The music, the power and the vibe of an Italian supermonster! Look at these
Italian guys trying to start up this F1 car, and turn up that volume when
it finally starts. Enjoy the music transmitted by this beast/beauty.
Dont forget to look on my channel for more videos! I would appreciate your
comments and thumbs up! :D
Ferrari Formula 1 - Engine warming up! LOUD SOUNDS!!
Here is a video of a Ferrari Formula 1 car I have recorded in the pitbox of
circuit Spa Francorchamps. Before this F1 car went on track, the guys from
Ferrari warmed up the engine. Enjoy this EPIC video with amazing loud Exhaust sounds!

Engine Running NO OIL - NO SUMP - Seized Soild on Camera
Messing with a Mitsubishi Lancer
There are loads of videos where people run an engine at full rev with no
oil in it, and the engine seizes.
Running it a medium rev, I wanted to see how long it would run with no
lubrication, and I was surprised.
However if the car was driving and the engine was under load, it would be
dead in minutes!
Formula 1 Engine Sound Comparison: V8 vs. V10 vs. V12
This is a video I made to compare the sounds of three of the best naturally
aspirated F1 engines ever produced; Ferrari 056 2.4 litre V8 equipped on
the F2008, Ferrari 051 3.0 litre V10 equipped on the F2002 and Ferrari 044
3.0 litre V12 equipped on the 412 T2.
These cars were all recorded in the same place so you can perfectly tell
the differences between them.
