I think it means he's full of shizzle. Now everyone thinks they have to double clutch when drag racing and don't even know what it means.

G2, I'm surprised you don't do this. Our cars are notorious for having the synchro's go bad in 2nd. This method is still used at the track as an alternative to replacing the transy after the synchro's fail. There is no time advantage to doing this at the 1/4's for our cars that I can think of, I just wait for the tach to fall before I pull it in to 2nd (called rev-matching, the only way to shift). BTW 7 points to the first newbie to ask about heel-toe in SuperHonda v4.0!
You shouldn't need to double-clutch while upshifting, but you should do it when you down-shift to make sure the synchros align. Also heel-toe with that if you are really concerned about preserving that transmission. Seems a little excessive to me to double clutch, but Tuan suggests it.

There is no need to double clutch if you know how to rev match. You don't need to heel-toe to rev match. It should be used for cornering at the track. You really don't need the clutch at all except for first if you know how to rev match.MN91TEG said:

Re: OK I'LL BE THE IDIOT
you dont double clutch in a drag race
double clutching is when you down shift, say youre in 4th, step on the clutch, shift to neutral, let go clutch, rev to the sweet rpm point, step on the clutch, then shift to 3rd autox racer does it , NOT drag racer
lolz you dont have to worry about it , what they say in the movie is just stupid,monkeyteg said:

Thats the exact meaning of double clucting. Double Clutching is used in Auto Crossing, the whole point of it is to have lower RpM.

Ya...what Vtexsex and LABlue said... Fast and the Furious writers were just trying to act like they know what they're talkin about and trying to use all these technical terms so the average person doesnt know what the hell theyre talkin about... The whole movie was pretty wack... Only like some of the cars in there. But cant complain, its the only movie about the import scene that made it on the big screen
Here is the real scoop............I used to drive a tractor trailer and the term double clutching comes from pumping the clutch twice to keep the flywheel spining, so it will go into gear easier. No semi manual transmission uses syncronizers, so they teach rookies to do this. Once you have practice this becomes pointless, as you are good enough to match rev and even the clutch is never used, except from a dead start. The writers in that movie were idiots and were way off in so many aspects of reality, maybe if you had a Ford Model T then you would double clutch.
Double-clutching is the proper way to downshift at speed without placing excessive wear on the transmission's synchronizers. This lets you to select a much lower gear without lurch you normally get when the clutch is let out after downshifting.
To prevent excessive synchroniser wear, the clutch is depressed and the shifter is moved to neutral. The clutch is then released, and the gas is depressed to bring the engine speed up to where it needs to be for the lower gear. The clutch is then depressed again and the shift lever moved into the lower gear. When the clutch is released the second time, the engine is already turning the proper speed .
hope this helps you..

Double clutching and rev-matching are two different things. You basically double clutch to relieve stress from the synchros.. you rev-match to relieve stress of your clutch. Since in double clutching you accelerate engine AND transmission speed, your synchros does not have to do the work of speeding up the tranny to match the engine speed (which it has to do for rev-matching, since you only accelerate the engine speed NOT the tranny speed). However you use the clutch twice as much when you double clutch (duh), so its up to you which one you want to go easier on, the clutch or the synchros.
And BTW, the quote about double clutchin on FnF? that was the stupidest thing i have ever heard.. you never double clutch on a drag race.. it is only practical for downshifting... you do it if you want to accelerate out of a turn in autox ... this is also done when wanting to downshift to slow into the turn, in which you would use heel-to-toeing which is more like an art
Double Clutching has really nothing to do with the clutch. It is actually very hard to do. What you do is hit the gas an extra time to keep the rpms high when you shift. Its easier on the car than power shifting and it does the same thing. You have to be very fast with your feet to do it and it takes a lot of practice and timing. I personnely can not do it i have tried a few times and it never seems to work out better then just quick shifting. Thats how my nieghbor explained it and he is very good at it to. I know once you master it it can help a lot. He runs a 16.2 in his 95 200sx Se, model which is faster than most SE-R's.
In old trannys, or in worn trannys, the synchros may not have much friction or none at all. Then, you need to spin up the input and countershaft manually. To spin them up manually, without being in a gear, you select neutral, then let the clutch out (engage it). If you blip the throttle, it will spin up the input/countershaft and, if you do it well, you will then be able to select the lower gear.
THE ONLY ACCURATE MEANING OF DOUBLE CLUTCHING...........
----------------------------------------------------------------------------
The idea of double clutching is to always select netural before a downshift, blip the throttle, then clutch in, then select the lower gear. This is meant to either save your synchros or to be used on trannys that don't have synchros.
The short of it is that you have synchros in your tranny that make double cluthing not required, hence the necessity in Semi truck shifting.
