Double de-clutching is wierd.

In the elderly cars that require it, the sequence was thus:
Press clutch down, take out of gear, release clutch.
Press the loud pedal.
Press clutch down, engage gear, release clutch (crunch).

It CAN be used going up the gears, but the most popular application is during downshifts - the idea is to match the engine cog speed to the anticipated gearbox cog speed for a smooth shift.

I prefer synchromesh.
 
well famine, i've been driving for 4 years and i claim to have mastered it heh. i probably would have claimed that after a year of driving but im basing it on the fact that i drive almost daily in london now, in all sorts of traffic conditions/speeds/weather and its been a good couple of years since a situation took me by surprise...

but why do they say in FaF that you should double clutch when going UP the gears? My definition of double clutching may be wrong, but Ive always thought that its another term for heel toeing...i could be wrong tho.
good point im not too sure why vin diesel says that. but then the movie does go over the top some times, "over night parts from japan" do they need to be overnight? :D heh anyway...

double clutching like famine said is when u rev the engine whilst u are in neutral and in between changing gears. heel-toe is when u do that whilst braking (that requires slightly handier footwork so its called a different name).

i've heard that when drag racing a good technique (for speed, NOT for the health of ur machine) is to keep ur foot all the way down on the accelerator even whilst ur changing gears. when u engage the clutch the revs will go up a lot, and when u re-engage the clutch after selecting the next gear the drive-train will be unsettled, u might even wheelspin if u have enough HP.
why?
well in turbo cars this clearly keeps turbo revs up, in NA cars it has slightly less effect but it still keeps engine speed up all the same. i think i've heard that referred to as 'power shifting' but i could be wrong.
maybe thats what vin diesel meant, although it is essentially the same as double clutching, u aren't trying to match revs, you are just keeping engine speed up so u can accelerate as fast as possible, which is the whole point of a 1/4 mile run.
 
I've covered roughly 60000 miles in 3 cars in those 8 years. I was born, grew up and learned to drive in Sheffield, so adverse weather conditions are first nature, never mind second. I'm a better (road) driver than most, simply because I'm aware of anything even remotely near the road at all times - my girlfriend has given up saying "Did you see that xxxxx?", because I did. :D However, I'm not perfect, infallible or a master of my art. As Lt. Cdr Data says:

"Believing oneself to be perfect is often the sign of a delusional mind*

Now where's that pink hippo gone? Nurse! Nurse! I want my sweeties. I love you - you give me sweeties. The yellow ones, the blue ones - they make the voices stop.
 
i think anyone in the UK can say that adverse weather conditions are a way of life here heh, however we do tend to have what i consider to be perfect driving conditions much more than other nations, i.e. cool weather, grey skies but no rain (hey thats what autumn and spring look like!) :D not to mention summer half the time...

P.S. in relation to this topic i've just discovered the sport button on on of our cars. i mean i knew it was there before but i didn't think it could improve throttle response until i started using it 100% of the time, rather when i just wanted to overtake someone/beat them off the lights. still nothing beats a manual in terms of driving fun.
 
Erm... Wait, can you guys explain Double Clutching, Heel-toe, and power shifting again... :/

I'm just a guy trying to get down some manual tips before I actually try them..
 
heel toe shifting:

use it when im at the track. basically you use it when slowing down to enter a curve. for example, lets say you are in 5th gear, about to enter a turn that requires you to be in lets say 3rd. so what you do is:

1. step on the clutch, pull it out of 5th
2. while doing so you "blip", or step on lightly the gas pedal WHILE doing the same thing with the brake pedal. You do this so that you keep the revs up, also to match the speed of the engine and the tranny.
3. step on the clutch and put it in 4th.

so you repeat these steps again if you want to go to a lower gear. it helps your car to have more power when going out of a turn.

my advice, get lots of practice....:)
 
Power Shifting is timing the shift just right so you don't have to use the clutch....Most cars have it low in the rpm's but it leads to excessive transmission gear/teeth wear
 
just imagine....racing...getting to 6,000 rpm's then using so much force that it goes into gear...OR!!!!!!!! taking the cars rpm's up slowly..and lightly pulling it into the next gear....And at the certain rpm..it'll fall into place
 
I thought powershifting was when you still use the clutch, but you never remove your foot from the gas pedal?

I've always thought what you're describing is just called clutchless upshifting. I've never seen anyone do that in real life, but I did try it in a friend's car, and his car wouldn't allow it to go into gear no matter how hard you yanked on the shifter.:irked::lol: I remember reading some magazine where the editors did it in a new Z06 to pull the best 1/4 mile times.
 
No that's quick shifting...That's the term I learned for it anyway.........And I do that all the time..Lol....It's easy...
 
There's also this crazy clutchless shifting that you do in this CRAZY car called a MR-S..Which isn't actually crazy...and is pretty slow and ugly and uncomfortable..but since it's a electroncly controlled gearbox...it's a semi-sequential tranny So all there is to it is "click-click-click"
 
Yeah, and there is also this thing called 'Post Editing' which is editing your first post so that you don't make heaps of useless posts.

It's crazy as.

like black eg says, to double clutch, you push the clutch down, move the stick into neutral, take ur foot off the clutch, press down on the accelerator (so the engine revs up) then let go, push the clutch down, move the stick into a gear lower than the one you were in, release the clutch, and hopefully everything will be smooth and you wont notice any weight shifting in the car. of course this takes a great deal of practice to get right. and you really have to know ur car to do it. u can't just get into a new car and perfectly match the revs first time. (though with practice u wouldn't be far off).

heel toe is the same thing but with the 'toe' of ur right foot pressing on the brake at the same time as you push down on the accelerator (with the 'heel' of your right foot) to increase the revs, just as before. i find i tend to use the side of my foot for the accelerator and the ball of my foot instead of the toe. but ball-side doesn't quite ahve the same ring to it as heel-toe. heel-toe actually comes from old ferrari cars where the clutch was in the middle apparantly... but i dunno about that.

as for power shifting, like i said before and like josh seems to agree with me, its changing gears (with or without a clutch) but never taking your foot off the accelerator (i.e. its constantly flat on the floor).

but please remember you don't need ANY of these techniques in your driving test, and dont attempt any of them before you are 100% comfortable with normal shifting.

there is a large amount of info on the web about heel-toe and double clutching. like famine said, in the old days before synchro-meshes, you HAD to double clutch or your gear system would mess up of refuse to get in gear at all...

for the more experienced drivers out there a good way to start off double clutching is when you are downshifting just move ur stick into neutral, bring ur foot up off the clutch and then push down again and shift. it will get you used to adding extra elements into the shift. then u can try blipping the gas pedal after bringing the clutch up.

there's a roundabout that i drive over frequently where the limit is 40, and you should really drop down a gear before you take it, which i do but double clutching means i don't have to slow down to get a smooth shift, so in effect i can take it much faster than everyone else. it always surprises people trying to follow me when i take it at the limit... (on a side note i did that once with cops sitting on the side road, they thought i was doing over 60 so they pulled me over, but with no video or radar evidence they had to let me go...)

hope that helps clarify the differences quicksilver!
