My 1977 MGB is a great car for learning how to heel and toe double declutch when downshifting just like the race car drivers of yesterday. A smooth heel and toe downshift is an art form and really helps on the twisty bits where balance and control are helpful
What happens in the transmission when you double clutch / Heel Toe Downshift???
Trying to do everything in one take is nerve racking, as it's nearly
impossible to do perfectly. Minor corrections: I said the clutch pedal and
throw out bearing are not wear items, I meant not high wear items, compared
to the clutch disk. Also, when I mention buying a cheap car to practice, I
mean if you own a manual transmission track car that is not your daily
driver. Finally, I didn't talk about the syncros. You can do this with
one clutch pedal action, but you make the syncros speed up the intermediate
shaft. When you double clutch, you bring the intermediate shaft up to
speed with the clutch disc, which has more capacity to do so than the
synchros. Minor point, but you will see prolonged synchro life when you
double clutch. Also, it is not the mass of the servo or engine but the
power created by electricity of gasoline that is responsible, but the mass
is responsible for the inertia.
How to heel-toe double clutch downshift in a classic MG sports car
Old British cars often have worn transmissions and with these techniques
you can make them downshift with ease. Learning to double clutch while
downshifting can dramatically reduce wear to an old tranmission and it's
fun! You can see our cars for sale at Bugeyeguy.com

PLEASE READ INFO FIRST!!! b4 asking questions. Its a 2005 mini cooper S, i
am filipino. The mini has a borla Exhaust and alta cold air intake and a 17%
reducation pulley. i remade the advanced part to make it shorter and to get
rid of that annoying crackling noise in the last one. if u want to see the
moves in slow motion, i made another vid just for that
SLOW MOTION OF THE TECHNIQUES
i also am adding the videos where i learned all of these from. he is greg
from the m5 driving school and he drives an m5 so his hard launch you
should follow if u have loads of torque
HEEL AND TOE THEORY
HEEL AND TOE DEMONSTRATION
Atkinson 1971 Silver Knight lorry. mp4
This is a 1971 Atkinson 'Silver Knight' timber crane. It spent most of it's
working life as a tractor unit pulling trailers loaded with bricks and pre
cast concrete buildings for it's original owner based at Aylesbury
Buckinghamshire U.K. It has covered a considerable mileage with no reported
breakdowns.The design dates back to the 1930's with a cab frame constructed
of angled steel and timber. Early cabs were faced with 'tin' sheet but this
was changed in the 1960's to the new fangled fibreglass. No air sprung seat
in this cab and a young lorry driver of today may complain of the lack of
power steering and pain in his left leg due to the lack of an air assisted
clutch. No sleeper cab either for our pampered driver. His 'bed' consisted
of a home constructed board placed on the central engine cover and
supported by the seats. Oh and did I tell you that a cab heater was an
optional extra in 1970..? Saying this the Atkinson was considered to be the
'SCANIA' of it's day with it's wrap round windscreen and relative comfort
compared very favourably with vehicles from the previous decade. It is
surprisingly a pleasure to drive and the old vinyl seat is very
comfortable. The engine has a powerful roar that was music to the ears of a
'traditional' lorry driver of it's day. The gearbox is a David Brown six
speed constant mesh i.e. no synchromesh, requiring the driver to match road
speed to engine /gearbox speed to enable smooth changes. This driving
procedure is known as double declutching and would open a whole new world
to our young driver.Get it wrong and you crunch the gears horribly [Ha Ha!]
or come to a complete stop before you could once again engage first gear
and start all over again! The engine is a road modifed Gardner 180 bhp
which was widely used in marine applications, very reliable and economical.
It's original design dates back to the 30's and were produced in four, five
and six cylinder versions. The engine design slowly evolved with
improvements made where a definite modification would improve efficiency
and build quality. This ensured reliability which is probably the most
important factor in the haulage business. The cost of diesel fuel back then
was not the problem as it is today.180 BHP sounds very small compared with
the 400bhp engines found in modern lorries but it easily pulled a 40 ft
trailer and formed the backbone of the heavy haulage fleets of it's day.
ERF and Foden were also noted users of the Gardner engine particularly with
their tanker and tipper bodied vehicles They are not a fast engine but pack
terrific torque relying on the skill of the driver and his use of the
gearbox to keep things moving. The Exhaust tends to smoke a bit when first started
but this soon clears when under power and the engine warms. I say warms
because the Gardner is a very cool running engine.
With the arrival of the motorway network in the 1960's more speed was
demanded by the hauliers and Gardner introduced the incredible straight
eight 240 BHP engine for use in maximum weight vehicles and Atkinson began
to offer the Cummins and Rolls Royce diesels as alternatives. Gardner
engines were well loved by haulage companies and workshop mechanics but the
days of the night trunk drivers slogging up the A1 were beginning to be a
thing of the past. The white hot period of Gardner engined heavy haulage
fleets was nearing it's end.
After retirement by it's original owner the vehicle was converted to a
timber tractor and was used for this purpose for a number of years. It is
fitted with a heavy Garwood winch driven by a 1955 six cylinder BMC diesel
engine via its original gearbox. It is now in preservation and attends
vintage vehicle and steam shows during the summer. Viewing the clip since
upload I feel the driving bit is far too long so if you get bored, just
fast forward through it! I hope you find at least parts of this video clip
Demostraciones Punta - Tacón y Doble Embrague / Heel & Toe and Double Clutch demostrations
Recopilatorio de demostraciones de las mismas técnicas en diferentes
Vehículos de distintos años, segmentos, características, pesos,
Cada vez con un calzado diferente, simplemente para demostrar que el tener
unas Puma o unas Alpine Stars no implica ser mejor conductor.
El vídeo está realizado a modo didáctico para todas aquellas personas a
las que el Doble Embrague y el Punta - Tacón les suena a chino.
A algunos de los habituales les costará reconocerme al no ver directamente
los calcetos de competición, jejeje!
He de agradecer a Danthrax el filtrado de los sonidos. ;)
Espero que os guste y que sobre todo la gente que descubre estas técnicas
por primera vez tenga muy en cuenta la petición que realizo al principio
POR FAVOR NO INTENTE IMITARLO,
REALIZAR ESTAS TÉCNICAS REQUIERE
