Double clutching is used to match rpm and transmission, when you down shift into say second you have to let the clutch out slower and the engine slows down the tranny therefore slowing you down which is good for everyday driving, if you double clutch you can pop the clutch when downshifting and keep a high rpm and keep the tranny spinning at the same speed as the engine which wont slow you down nearly as much ... this eliminates shifting times and you keeps your revs high... great for racing!!
Double clutching are for race cars older that 20 years or older, new cars you don't need to do that now, foot on ACC and the trans is modern enouf to accept the abuse of road racing
double clutching makes it easy to downshift from say fourth gear, right into second gears powerband as quickly and painlessly as possible by matching the revs while in neutral to what they will be when you put it into second gear.
@joshthompson202 I agree with you that double clutch makes it easier and smoother for putting the car into gear. with proper rev matching, it's just easier to the move the shifter lever with as little resistance as possible into gear.
You are called a troll because you only comment , everyone has an opinion and your doesn't count , did I ever say it had to do with what you "think" you know? No your too dumb you expand , but your comments tell me what you really know pirate boy......must be another backyard wannabee mechanic and I upset your little world with the facts
@holg0051 you are not worth a response you have never even uploaded a video, you do not double clutch a mini or float its gears I drive a rig its unsynchronized thats is when you do get a clue before trying to be witty and try actually putting up videos rather than trolling to comment
@teamsterjeffrey you define my knowledge about cars on how many videos i have uploaded to youtube? you are truely more retarded than i thought was possible nuff said
@fredericobpc Double clutching is where you clutch, shiift to neutral, clutch again, than put it into gear. This is used in an unsynchronized transmission. Most cars after about the 1950's have a synchronized transmission so you don't need to worry.
man people are dumb flat shift is shifting up only this is dangerous on the engine if you mis-shift by hitting the gate, double clutch on the way down is needed as in racing you don't have time as a luxury so using the synchro to shift down slowly is useless and just changing down a gear and letting off will violently upset the car, double clutch match the revs and you can shift down fast without upsetting the car...SIMPLE
@blinksta187 double clutching, if your racing a truck... or driving a car from the 40s? youve been watching fast and the furious too much... you dont "double clutch" in racing, it wastes time, single clutch, match the revs... done...
how did this kid fool 300,000 people.. that is not a true double clutch.. double isnt even a proper word for a double clutch.. they just call it that in the street race scene.. i true double clutch is you never letting off the gas.. clutch and shift as fast as possible.. no let off clutch gas shift un clutch.. YOUR WASTING ENERGY.. while i just flew past in the same exact car... SET IT UP.. WE'LL DO A VIDEO ON THE TRUTH TECHNIQUE FLYING PAST YOUR GOOFY FEET SHIFTING hahahahaha
@MrCamTodd Think you're a bit mixed up. That is flat shifting where you don't let off the accelerator. BlackFlagProperty is right with the synchronized transmission. The gears in older gearboxes weren't synchronized so they didn't mesh easily. You had to double clutch to get the gears to engage. Don't let the fast and the furious fool you. They don't really know what they are talking about.
the newest car i have driven (stick shift) with the gas pedal and brake pedal on the same plane so you can heel toe it was my old 94 nissan sentra. every car since then (that i have driven) has the gas closer to the floor and the brake and clutch closer to the driver making it very difficult or impossible to heel toe. glad to see mini is doing good work.
Why do u double clutch? To rev up? You can do that while shifting .. still only useful for drag races and it will fuk up your "engagement disks" (translation might not be perfect here)

these videos are really cool why dont you update us since the minis tranny sucks and tell us how many times you replaced it now, i watched the shifting without clutch vid....this isnt an unsyncronized tranny you are going to break it ...for those out there trying this save up youll need the money
@teamsterjeffrey update: mini is running great, no problems with it. never replaced the clutch or transmission or anything. if u read the description of the "shifting without clutch" video you would know i always shift with the clutch. just cause i made a video on it doesnt mean i never shift with the clutch.

Wow. Really? I assume you're talking about the italian job movie? Dumbass. Mini's fucking suck. You need to be a midget to even fit into one. I'm 6'0 160, and i barely fit in the friggin' thing.
@doublesomeday No...it doesn't go 150...it just says that on the speedometer, doesn't mean it actually goes that speed. And my car "smokes tires" from 1-3...doesn't mean its fast...although it's faster than your gay ass vehicle. Good Night Sir.
@Manny4g63 actually im not entirly sure, but id say youv never been in my car? iv seen the needle pointing directly at sain number, "150". so unless you have a wonderfully convincing argument to prove that the needle lied to me than yea, my car goes 150. and good for you that your car can roast 3rd gear, notice i didnt say that my mini is the most powerful car in the physical universe! i said its no bitch, so unless you can prove me a liar and unless you think that 150 is slow, i win
Single clutch makes very little sense to me, in that I have to go through a mindfuck of a thought process just to get my hands and feet to do it... double clutch is infinitely more natural and makes much more sense. I think it's because I have very rarely downshifted when I began driving and got used to basically a super slow double clutch : In gear -> Neutral then roll to red light -> Revmatch & back into lower gear at green. Then when I needed to quickly downshift I just sped up the process.
Had a cooper s for 7 years before, most of these techniques are useless in todays cars, only one i have used all the time is heel toeing which i use all the time, but in the mini it is way easier and more controllable to use the ball of your foot on the brake and the right side of your foot on the accelerator. Depends on your cars pedal spacing and the size of your foot, but mine are average! Good for smoother entrance into the corner under braking to keep the car balanced.
Oh and not to mention it is also more wear on the throw-out bearing. All double clutching is, when syncros dont line up correctly anymore, when you push in the clutch the first time it allows you to pull out of gear, release the clutch and push back in to slide shifter back into next gear. In some cases you have to tap the gas to bring RPM's back up to realign your gears so it doesnt grind. Otherwise it will just grind all day long until the gears slow down or speed up.
Heel and toe is not for racing, while your messing around with that I would have grab the other gear and pull ahead of you before your heel ever hit the gas. It is not easier on your clutch to double clutch, only if the syncros are out. That is for people with bad tranys that dont want to get them fixed. If anything, it is worse for the clutch basket with all the extra movement causing weaker springs.
That's awesome, another technique i wouldn't have thought to share. :) Double clutching is for race losers. With our similar driving traits, Can i ask. If you could have any car, what would it be. (obviously, a toss up) Don't say mini.
He revs then in fraction of second throws into gear then release clutch. I find that its smoother if you brake, clutch, throw into gear,rev match,release clutch. It just works better for me.
Now, what is the point if your in a newer car as newer cars need none of this. In a semi I could see, not a car. An older pickup from the 50's, I could see, not a newer car. A stupid video as I have drove many manuals and I never once had to do any of this.
@duane2072 Same here; 2 Gremlins, 1 Granada, 1 Pinto, 1 Plymouth and a couple of 5 ton trucks; never double clutched, never grinding either. As I depressed the clutch the shifter went into the next gear (up or down) and then I released. Typical shift took less than a second. It was in the next gear by the time the pedal hit the bottom. Never had any problems with any of the vehicles tranny's. Most had over 100K on them.
Most of them are not needed. Like he said, Heel Toe if for racing but it't still fun to learn. Double clutch is pretty much pointless now, but i use the single clutch technique all the time. If done properly it is easier on your clutch and it makes the ride more smooth, especially if you have a passenger.
@mdr279 timing. you must match revs while in neutral and the clutch is disengaged. also to answer someone else's question. this technique is nessecary for nonsynchronised gearboxes. (such transmissions are more durable, that's why they are used). in single clutching process you don't have to disengage the clutch when in neutral, and as long as you blip before dropping the clutch you generally should be ok.
@turboturtle2002 Yeh I knew the difference in how they are performed but in a synchronised gearbox, are both methods equivalent in what they achieve? Is double-clutching unnecessary?

rev matching isn't exclusively a racing technique or necessary for gear without synchronization.
Even for usual cars on public road rev matching is useful to enhance life of clutch and gear and to enhance the riding comfort for passengers avoiding the car shaking when shifting down. Moreover, you can shift down without loosing speed, specially useful when going uphill.
I use this technique everyday in a normal car without thinking about anymore.
double clutch up shifting comes in handy if ya need an extra little boost of speed, just gotta watch the rpms not to blow anything. The techniques you show are popular in drifting, so any novice to should pay attention to how its done. I'm looking to get a rwd car and start drifting, your video is helpful in showing both techniques, heel toe is a little weird but useful.
@martian010 not really, if you want extra boost, power shifting is the way to go. but even then, if you speed shift fast enough theres no point to powershifting. (fast shifting is all in the foot, not the hand)
so while u going to lower gear u revmatch?, so its almost like ur revving in neutral, except u dont stay in neutral u moving along neutral? am i right? im sry i just want to know the best moment to revmatch, lets say from 4 to 3 gear, u dont rev at 4 or 3 gear u rev in neutral?, thats revmatching while u shift right? plz help
@joeaccord23 1/2 that is correct. You rev match in neutral with your foot off the clutch. Then you press the clutch, switch to lower gear, clutch out. If you rev match while pressing the clutch you fail to make the input shaft of the gear box spin at engine rpm, and therefore the synchros will have to force it to move faster before you are able to move the stick into a lower gear. Try going 20 mph and switching to 1st with both techniques (single clutch rev match vs double clutch rev match).
@joeaccord23 2/2 You will experience that if rev matching perfect while double clutching, your gear stick will move into 1st silky smooth. If only single clutching and rev matching you will have to force it into gear.
To me, it just looks like you give it gas before releasing the clutch. Is that right? So when you get into gear, you get a bit of a boost up the revs?
Are single and double clutch downshifts two different techniques for accomplishing the same task, in which case the drive uses whichever he prefers? Also, is a heel and toe downshift essentially a single clutch downshift while braking?
@ninincnals depends on your driving style.... single clutch rev matching works just fine but since double-clutching reengages the clutch it causes a pause in your rpm band where as single-clutch rev-matching has a constant rpm slide to it... basically DC stops needle momentarily, SC has to be stopped by throttle control.
what a bullshit!!! next time - while shifting gears - try to get out of the car, run around it, jump on the roof, do 40 push-ups, and go back to the car. Everything while doing 100 km/h of course :)
xrated335 hit the nail on the head. However, you don't really need to double clutch in an ordinary street car because most car transmissions are syncchromesh. Long story short, you don't have to match the engine speed to the wheel speed. If you are driving an heavy truck or race car, the transmission is not synchromesh. So you have to match the two speeds yourself by double clutching.
If you want to see the best heel and toe techniques then watch one of the car battles in Best Motoring. God that show rocks! Although I do appreciate the effort put into this video.
This comment has received too many negative votesshow
double clutching is for pussies, heel and toe I'll try it then pass judgment, rev matching is also for pussies who cant handle their clutches, i down shift all my gears from 5th to first without getting those awkward jerks, learn how to use ur clutches
ha ha ha HOMO, ever heard of racing ? dick, 5th to first is for pussies, any good racer uses heel toe, watch a v8 supercar race. every think that people want to learn this for other reasons not just you useless grandma drivers. Nice work s0ggyrice
LOL i was waiting for some 1 like u to comment, well home boy i never passed judgment on the heel toe shifting cause i never tried it. wen i do you'll be the first person i let kno wat i think... personally, ive benn there done that i dont race ricers anymore, yes ricer is actually a word... i'll tell u about it after tha weekend, im out home boy
The idea is on a down shift, You blip the throttle to bring engine speed closer to that of the transmission input speed, so that when you come off the clutch, you dont get a compression lock up and end up in the scenery. I do it in my road car sometimes, too.
yes you can... you can downshift without even braking if you want. But like he said, heel and toe is a racing technique so basically you slow down (brake) and downshift at the same time RIGHT before a turn. you can downshift on a straight road w/o brakes and you will slow down a little (engine brake) but its not a major braking
yeah, it's just a technique to get a smooth downshift while braking. can be used anywhere you want to slow down and shift at the same time, mostly for corners though.
if you need to turn and downshift Heel toe Is the smoothest way to do that to get ready for the next gear exiting a corner or such.. =].. though its friggen hard to do still practising it =[
If your engine was at 3k rpm in 3rd gear, and you dropped to second whist not giving more "gas" the engine would jump to 4k rpm (not exact) to match the transmission speed.
So, when switching gears you rev the engine up in an attempt to match the speed of the car in second gear as it was when it was in third, thus alleviating stress on the clutch, transmission and crank shaft and making for a smoother ride. This is very important in sports performance cars, as you will be dead if you don't.....
make sure it's rear wheel drive and if still understeering into corner, tap brakes upon entering, then power out. should cut the back end out if done correctly
trail brake, and/or use proper left foot braking techniques, be very very careful when learning these though, get somewhere with good runoff area, like a track or skidpad, or big empty parking lot with imaginary curves. just in case you try to carry too much speed into a corner. look them up.
It is to match the engine speed with the wheel speed. You shift into neutral so the engine drive shaft is spinning faster when you connect to the wheel drive shaft. It reduces load on the clutch plate too. If you get the engine speed and wheel speed mismatched, you can create a braking effect in the drive wheel. If you are at the limit of adhesion (i.e. racing or tracking) this will reduce cornering grip and potentially spin the car (RWD) or understeer (FWD) if there is a lateral load
@mr94silverado It does, it is just more difficult to do accurately at speed...try it. Double clutching is a (an old?) racing technique designed for non-synchromesh gear boxes for fast gear changes in a 'normal' manual transmission. It reduces wear on the gear box and clutch amongst other things, and also allows a more control gear change that prevents/minimizes the impact of engine braking on the wheels. This can unsettle the balance of the car. More...
...in a straight line, it will cause the car to brake too much than is needed for the corner. If you are "threshold braking", i.e. at the limit of the tire grip, it will cause you to skid and lose control. This costs time to regain control and will put you off-line and reduce your exit speed that will affect your whole lap. If you are in a corner at the limit of traction, the extra braking will cause the wheels to lose traction. If it is FWD, this will cause the car to understeer....more
and a RWD car will lose grip and oversteer and probably spin. A good book to read is "Going Faster" from the Skip Barber racing school which discusses all of this in a good level of detail without being too technical. Anyway, rev matching is tough to do accurately at speed, whereas double clutching allows a certain amount of latitude with gear revs (better to be slightly too high). Day to day, it doesn't matter as you never need that level of precision control the car
@vakeritoguero NOOO!!! ¬¬ THIS!! It is to match the engine speed with the wheel speed. You shift into neutral so the engine drive shaft is spinning faster when you connect to th etc etc etc
whats the best way to downshift in regards to the health of the clutch and transmission? would it be best just to slowly let of the clutch pedal and gradually let the gear engage without adding gas, or will that cause harm? are there any professional opinions?
40mph in 2nd turns more rpm than in a higher gear, therefore you bump the throttle to compensate for the rpm difference when going into 2nd from say 3rd.
save the clutch so ur not burning it. u just rev match down shift in neutral basically and when at the right rpm clutch in and should be at the right rpm. alot of people use it in high end cars were the clutch costs a good 3k or more
It wastes the clutch no more than regular rev matching. Perhaps the tiniest bit more from bringing the transmission up to speed, but this is trivial.
It actually saves the synchros. Think about it. If it makes a unsynchronised transmission shift properly, it will make the synchros in a synchronised do little to no work, saving them.
emtrixdk, you're not particularly helpful or civil. You can't insult someone then say "peace", that's quite stupid.
the synchros dont jump to the side and let you manualy sync the gears,
sync gearboxes run syncro's everytime the clutch is depressed, there for you speed the syncro up then stop it then up again, making it work twice as hard,
No, they don't "run synchro's" when you depress the clutch. The synchros work to match the speed of the gearbox to the wheels only when you push the gear lever into a gear. That's why, for example, if you try to shift into first or second at speed, you have to push the lever for a bit before it goes into gear. The whole point of double clutching is to manually sync the gears. If you do most/all of this matching yourself with clutch/throttle manipulation in neutral, the synchros do less work.

Now, what is the point if your in a newer car as newer cars need none of this. In a semi I could see, not a car. An older pickup from the 50's, I could see, not a newer car. A stupid video as I have drove many manuals and I never once had to do any of this.
duane2072 6 months ago
@duane2072 Same here; 2 Gremlins, 1 Granada, 1 Pinto, 1 Plymouth and a couple of 5 ton trucks; never double clutched, never grinding either. As I depressed the clutch the shifter went into the next gear (up or down) and then I released. Typical shift took less than a second. It was in the next gear by the time the pedal hit the bottom. Never had any problems with any of the vehicles tranny's. Most had over 100K on them.

Most of them are not needed. Like he said, Heel Toe if for racing but it't still fun to learn. Double clutch is pretty much pointless now, but i use the single clutch technique all the time. If done properly it is easier on your clutch and it makes the ride more smooth, especially if you have a passenger.

What the difference between double clutch and single clutch rev match??
mdr279 10 months ago
@mdr279 timing. you must match revs while in neutral and the clutch is disengaged. also to answer someone else's question. this technique is nessecary for nonsynchronised gearboxes. (such transmissions are more durable, that's why they are used). in single clutching process you don't have to disengage the clutch when in neutral, and as long as you blip before dropping the clutch you generally should be ok.
turboturtle2002 10 months ago
@turboturtle2002 Yeh I knew the difference in how they are performed but in a synchronised gearbox, are both methods equivalent in what they achieve? Is double-clutching unnecessary?

rev matching isn't exclusively a racing technique or necessary for gear without synchronization.
Even for usual cars on public road rev matching is useful to enhance life of clutch and gear and to enhance the riding comfort for passengers avoiding the car shaking when shifting down. Moreover, you can shift down without loosing speed, specially useful when going uphill.
I use this technique everyday in a normal car without thinking about anymore.
sorry for my bad english.
heizoeli 1 year ago 2
So you step on clutch, shift to neutral, step on gas pedal (rev match), and finally go into lower gear. That's what I saw in slow-mo.
brbn93 1 year ago
double clutch up shifting comes in handy if ya need an extra little boost of speed, just gotta watch the rpms not to blow anything. The techniques you show are popular in drifting, so any novice to should pay attention to how its done. I'm looking to get a rwd car and start drifting, your video is helpful in showing both techniques, heel toe is a little weird but useful.
martian010 1 year ago
@martian010 not really, if you want extra boost, power shifting is the way to go. but even then, if you speed shift fast enough theres no point to powershifting. (fast shifting is all in the foot, not the hand)
PsykeOut193 11 months ago
so while u going to lower gear u revmatch?, so its almost like ur revving in neutral, except u dont stay in neutral u moving along neutral? am i right? im sry i just want to know the best moment to revmatch, lets say from 4 to 3 gear, u dont rev at 4 or 3 gear u rev in neutral?, thats revmatching while u shift right? plz help
joeaccord23 1 year ago
@joeaccord23 1/2 that is correct. You rev match in neutral with your foot off the clutch. Then you press the clutch, switch to lower gear, clutch out. If you rev match while pressing the clutch you fail to make the input shaft of the gear box spin at engine rpm, and therefore the synchros will have to force it to move faster before you are able to move the stick into a lower gear. Try going 20 mph and switching to 1st with both techniques (single clutch rev match vs double clutch rev match).
kjaks 1 year ago
@joeaccord23 2/2 You will experience that if rev matching perfect while double clutching, your gear stick will move into 1st silky smooth. If only single clutching and rev matching you will have to force it into gear.

To me, it just looks like you give it gas before releasing the clutch. Is that right? So when you get into gear, you get a bit of a boost up the revs?

Are single and double clutch downshifts two different techniques for accomplishing the same task, in which case the drive uses whichever he prefers? Also, is a heel and toe downshift essentially a single clutch downshift while braking?

Which is better, single clutch or double clutch rev match? Wouldn't a single clutch rev match be better because you only engage the clutch once?
ninincnals 1 year ago
@ninincnals depends on your driving style.... single clutch rev matching works just fine but since double-clutching reengages the clutch it causes a pause in your rpm band where as single-clutch rev-matching has a constant rpm slide to it... basically DC stops needle momentarily, SC has to be stopped by throttle control.

kinterodavid12 1 year ago
@kinterodavid12
xrated335 hit the nail on the head. However, you don't really need to double clutch in an ordinary street car because most car transmissions are syncchromesh. Long story short, you don't have to match the engine speed to the wheel speed. If you are driving an heavy truck or race car, the transmission is not synchromesh. So you have to match the two speeds yourself by double clutching.

The idea is on a down shift, You blip the throttle to bring engine speed closer to that of the transmission input speed, so that when you come off the clutch, you dont get a compression lock up and end up in the scenery. I do it in my road car sometimes, too.

you can heel and toe even if it's a straight road and not turning around a corner?
BoomerZero 2 years ago
yes you can... you can downshift without even braking if you want. But like he said, heel and toe is a racing technique so basically you slow down (brake) and downshift at the same time RIGHT before a turn. you can downshift on a straight road w/o brakes and you will slow down a little (engine brake) but its not a major braking
Laborchet 2 years ago
yeah, it's just a technique to get a smooth downshift while braking. can be used anywhere you want to slow down and shift at the same time, mostly for corners though.

What does rev-matching exactly mean?
hencethename02 2 years ago
If your engine was at 3k rpm in 3rd gear, and you dropped to second whist not giving more "gas" the engine would jump to 4k rpm (not exact) to match the transmission speed.
So, when switching gears you rev the engine up in an attempt to match the speed of the car in second gear as it was when it was in third, thus alleviating stress on the clutch, transmission and crank shaft and making for a smoother ride. This is very important in sports performance cars, as you will be dead if you don't.....

trail brake, and/or use proper left foot braking techniques, be very very careful when learning these though, get somewhere with good runoff area, like a track or skidpad, or big empty parking lot with imaginary curves. just in case you try to carry too much speed into a corner. look them up.

What's the double clutch for?
SONIX2332 2 years ago
basically, so you don't loose speed when you shift.
fifthoffence 2 years ago
It is to match the engine speed with the wheel speed. You shift into neutral so the engine drive shaft is spinning faster when you connect to the wheel drive shaft. It reduces load on the clutch plate too. If you get the engine speed and wheel speed mismatched, you can create a braking effect in the drive wheel. If you are at the limit of adhesion (i.e. racing or tracking) this will reduce cornering grip and potentially spin the car (RWD) or understeer (FWD) if there is a lateral load

@xrated335 Doesn't just single clutching and rev matching create the same effect?
mr94silverado 1 year ago
@mr94silverado It does, it is just more difficult to do accurately at speed...try it. Double clutching is a (an old?) racing technique designed for non-synchromesh gear boxes for fast gear changes in a 'normal' manual transmission. It reduces wear on the gear box and clutch amongst other things, and also allows a more control gear change that prevents/minimizes the impact of engine braking on the wheels. This can unsettle the balance of the car. More...
xrated335 1 year ago
...in a straight line, it will cause the car to brake too much than is needed for the corner. If you are "threshold braking", i.e. at the limit of the tire grip, it will cause you to skid and lose control. This costs time to regain control and will put you off-line and reduce your exit speed that will affect your whole lap. If you are in a corner at the limit of traction, the extra braking will cause the wheels to lose traction. If it is FWD, this will cause the car to understeer....more
xrated335 1 year ago
and a RWD car will lose grip and oversteer and probably spin. A good book to read is "Going Faster" from the Skip Barber racing school which discusses all of this in a good level of detail without being too technical. Anyway, rev matching is tough to do accurately at speed, whereas double clutching allows a certain amount of latitude with gear revs (better to be slightly too high). Day to day, it doesn't matter as you never need that level of precision control the car

why cant we shift down a gear like we sift up it?
looray99 2 years ago
put simply:
when you shift up, the rpms drop.
when you downshift, the rpms become higher.
40mph in 2nd turns more rpm than in a higher gear, therefore you bump the throttle to compensate for the rpm difference when going into 2nd from say 3rd.

emtrixdk 2 years ago 3
It wastes the clutch no more than regular rev matching. Perhaps the tiniest bit more from bringing the transmission up to speed, but this is trivial.
It actually saves the synchros. Think about it. If it makes a unsynchronised transmission shift properly, it will make the synchros in a synchronised do little to no work, saving them.
emtrixdk, you're not particularly helpful or civil. You can't insult someone then say "peace", that's quite stupid.
shigidab0p 2 years ago 2
the synchros dont jump to the side and let you manualy sync the gears,
sync gearboxes run syncro's everytime the clutch is depressed, there for you speed the syncro up then stop it then up again, making it work twice as hard,
thats why they are in the gearbox!!!!!!!! ,
PEACE
emtrixdk 2 years ago
No, they don't "run synchro's" when you depress the clutch. The synchros work to match the speed of the gearbox to the wheels only when you push the gear lever into a gear. That's why, for example, if you try to shift into first or second at speed, you have to push the lever for a bit before it goes into gear. The whole point of double clutching is to manually sync the gears. If you do most/all of this matching yourself with clutch/throttle manipulation in neutral, the synchros do less work.
