Double Clutching!

[Peter P]

I've heard the term thrown around a fair bit (most recently from the original Fast and the Furious film) but does anyone know an idiots definition of what this actually involves as far as how you work the pedal differently to a normal clutch down, select gear, release clutch..........................................???

Sorry if that is a thick question just been bugging me after a m8 asked what it mean't and I had to say I didn't have a clue!!!! :d :search:

Cheers guys,


Pete :)

Is that what the third pedal is for!

You mean double de-clutching. It's a complete waste of time since the invention of synchromesh!

[markrzs]

Exactly what NeedforSpeed says !

tried telling a mate that a while back and he was having non of it. Glad you've just proved my point

a fine example of the double de-clutch can be found in Bullet with Steve McQueen but this was pre synchromesh and in the 60's, best forget it its a thing of the past

[tbourner]

That would be true, except people who talk about double clutching usually mean heel and toe, which is different, and can be very useful in modern cars.

a fine example of the double de-clutch can be found in Bullet with Steve McQueen Actually that was another example of poor audio post-production. Keen fans of the film will notice the car has more than the 4 gears it was built with. The throttle blip is on the down-change not the up-change. Synchro has been with us since before the 60s.

If anybody wants to know how to do it, I'll explain. When you have mastered it you can change down without using the clutch at all - handy if you've had hydraulic failure (or a broken clutch cable - depending on the car) and you need to limp home.

To hear it at its best, go to a historic race meeting like the Goodwood Revival and listen to 1950s GP cars.

Try not doing it on a downshift on a TVR.. you will almost end up going through the windscreen.

Ive been in some big toys with BAD drivers who dont know how to do it and the drive is not comfortable at all.. when downshifting you get thrown forward and the engine breaking is just stupid

[Need4Speed]

Now we're confusing double de-clutching with the throttle blip (and heel and toe) to match the revs to the road speed when letting the clutch out again on a down change. The double de-clutch only affects the meshing of the gears... and the synchromesh will already have done that.

[tbourner]

See. :D

Double de-clutch is actually letting the clutch out when you've put it in neutral, blipping the throttle, and then pushing the clutch back in to go into the next gear!! I always used to heel and toe blip when changing down, just to smooth it out, but have never attempted double de-clutch (because there was no need).

My first car was a Mini with very marginal synchro so I learned to double de-clutch because it was easier than changing the gearbox.
