Lots of near misses, desperate passes, spins, crashes and over-revs (due to a faulty rev limiter) all filmed through the eyes of driver Beau Borders in his Formula Mazda at Road America in June 2012. It was the first time out using the Pivothead HD Glasses...
Go onboard with Doug Peterson at the start of the 2012 June Sprints at Road
America as he gets pinched against the front straightaway and rolls the car
at 100mph. Five competitors caught the shunt on tape - Carson Weeder, Beau
Borders, Sam Lockwood, Robert Noell, and Steve Jenks. Each driver had a
wild ride of his own - but nothing compared to what Doug went through.
Fortunately he walked away, but the same can't be said for his brand new
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).
Super car driver idiots [NO pics, only videos]
I got bored with all the "super car crashes"-videos here on YouTube that
only contained PICTURES, CRAPPY MUSIC or/and clips of pure racing cars on
official racing events.
This compilation DOES NOT include pure racing cars on official racing
events - only real life FAILures on the STREETS, made by people with more
money than driving skills...
(Though, even the best car drivers can crash too of course.)
Notice 1: The "Dodge Ram" may not be a super car, but still it's a SRT10
with the 8.3L Viper V10 which produces 510hp. Pretty super for a pick up,
don't you think? It has more power than several of the cars in this video.
The intention with this video was to show that skills doesn't come with
Notice 2: Tire is the preferred spelling in the U.S. and Canada. Tyre is
preferred in most varieties of English outside North America. And I'm from
Sweden. So please think outside your box (country), you who claims "tyre"
is incorrect spelling.
