Name the technique
Is this heel & toe-ing????
 
heel and toe??
VBH in an atom BTW

and using the technique speeds up what??
Gear changes/synchronising the engine speed with the road speed/increases the stability of the car under braking????
and basically you press all three pedals when you depress the clutch, thus blipping the throttle in preparation of the next gear being installed

Never heard that. I thought that was when folk CBA to take their foot off the clutch pedal - or slipping the clutch to get the motor back into the
power band...

here is a really good demo of heel and toe. Check out the vid at the bottom
of page, it takes you though it slowly - all makes sense at this speed!
Not yet managed to get it myself, more practice needed...

TBH if you are struggling to get the hang of this it may not be your fault. In some cars this is really easy, it just comes down to the spacing and
height between the pedals. For my size 11's I find french cars not too bad, but japanese cars pretty aweful. (Not saying I drive well though :-)

Its either heel and toe or too big a right foot
How long can i resist the temptation to drop a V8 in?

I can just manage it (very slowly though) in my old Nissan Sunny. But it is impossible in my Astra. There is not enough room for my 11 size feet and
especially ankle. When you see the Walter Rohl video, there is nothing around the pedals, so he can place his feet as he likes... So yes, difficult
technique, but depends on the car and pedal setup...
So the question is: How do we set up the pedals in the Locosts to be able to do this in the car?

Ref pedal position - is it about knowing how far down the brake pedal is when you get desired bite and then having throttle pedal at that height -
then enough space so you can get your double jointed ankle contorted across to blip the throttle with your heal whilst keeping toes on brake. All
within 4.68 nanoseconds before you get face whipped by the hedge on oustide of bend?????

Do it all the time in the Locost, can't reach in the tintop though. Allows for smoother gear changes, therefore less clutch wear. (that's
why I do it anyway - oh and it sounds good too!)

I'm assuming the atom is either a BEC or has a syncro box in it as from what i was taught.
with a proper normal gearbox you are supposed to clutch down into neutral clutch up rev engine clutch down slect gear clutch out.

All modern cars have synchro gears now. the technique you describe (double-declutch) is as you say for "proper normal" gearboxes without
synchro's, except that's "olden day" stuff now. It was required to enable you to get into gear full stop, not make things
smoother (ala heel/toe).

ahh crossed purposes. By syncro i didnt mean syncro mesh as i realise all modern stuff has that i meant push for up and pull for down..

Think sequential was the word you were looking for.

if you fit pedal extensions like OMP or sparco type that you can buy at halfrauds etc, put the two small ones on the brake and clutch and the big one
on the throttle. it gives you a bigger area to press when blipping the throttle.
the technique is difficult to learn and i find it can only be done properly at race speeds. i.e if you are braking very hard at the end of a straight
you should have the brake pedal nailed down as far as it will go. you can then blip the throttle without losing or more importantly gaining additional
brake pressure. if you try to heal and toe when driving normally you will not be applying full brake pressure and when you go to try to blip the
throttle you will almost certainly alter the pressure you have on the brake pedal. this will usually end up in you applying more pressure and sending
your passenger towards the windscreen.
the idea of the technique is to bring the gearbox internal shafts to the same speed as the flywheel / clutch to ensure a smooth transition when
changing gears.
most commonly used when changing down the box (shouldnt need to do it chen changing up in a car with syncromesh box.
the ideal way to do it is:
brake
clutch in
gear into neutral
clutch out
blip throttle (with clutch out)
clutch in
select next gear
this is very hard to achieve and most people including myself do this
brake
clutch in
blip thorttle whilst changing into next gear
clutch out
this is not as effective as the engine is disconnected from the gearbox by virtue of the clutch being in, but you do get some connection even with the
clutch in. you just have to blip the throttle more
hope this makes sense
cheers

I thought the idea of double declutching was to match the engine speed to the gear that you're going into (ie you speed up the engine when
changing down ) - necessary when using a crash box.
And I thought heel and toe was double-declutching while braking.
But maybe it's just a way of making a rorty noise to impress the girlies

hi,
all of the above is correct- the big reason on the racetrack is to prevent the extra engine braking you get when you change down and let the clutch
out- imagine you enter the braking zone and brake at the limit of grip, if you then chang down you add extra engine braking to the driven wheels-
which can lead to locking those wheels- possibly leading to a spin ina rear wheel drive car.
if you heel and toe, you maintain the same smooth braking to all wheels wheile changing down.
especially important with a light rear end like our cars!!
