double clutching is when u Clutch, take it outa gear Unclutch in Nuetral, Reclutch and put it into gear, its suposta hold pressure or something, truckers have to do it, its god for reacing if u get good at it, gotta be quick so u dont lose speed though

double clutching is done when you have an UNSYNCRONIZED transmision. the whole aim is to help the dog sliders get linned up with the next gear on the shaft.

you have a synchronized tranny this is not going to help you much if at all. im not going to get into explaining syncros here but
the concept is simple.

you move a syncro slider towards a gear. both the gear and the slider have say 30 teeth. the gear is usally spinning and the slider is locked to the same shaft. when you move the slider it pushes a brass ring on the gear which thorugh friction speeds up the gear to match the speed of the slider.when the slider teeth and the gear teeth meet the gear is locked to the shaft. thebry producing a powertrain. good luck.

hopefully this clear it up a bit.

the accord has a synchronized transmision.

and there are some beefed up aftermarket box's that are non synchronized. however you will never need this tranny becuase the axles will snap long before you reach this power level.

summed up, double clutching an accord is stupid, and fast and the furious is a movie, most likely made by directors, not actual mechanically inclined peoples like ourselves.

its fun though, when some moron who just saw the movie comes up to you and asks if your double clutching, and you go "yeah man", tell him how, then race him and listen to his wicked slow shifts, lol.

Alright i have heard a few different ideas on double clutching, and some of them dont make sense at all. I want all the people that have 5spd accords to try this for double clutching.

when your in second gear and u hit 2500-3000 push the clutch in and let it out real fast. Do it once or twice in second gear.

then once ur in 3rd gear and u hit 3000-3500 repeat it again,push in the clutch and let it out real fast one or two times.

once u have hit higher rpms with this in both gears u all know when to shift.

this does work and i have won races with this method.

push in on the clutch a few times around 3k in each gear???????? Am I reading this wrong???This would disengage the clutch from the flywheel and engine therefore slowing you down....right....The object is too have the clutch engaged to the engine as long as possible and have it disengaged as short as possible cause when its disengaged your engine ain't turning the clutch.....That post was wierd....can somebody explain it to me???

JTEUTON-- I READ WHAT U WROTE AND I DONT KNOW IF U KNEW BUT IF U WERE TO PUSH THE CLUTCH IN AND OUT REAL QUICK AND 3000 RPM THE CLUTCH WOULD BE DISENGAGED FOR A MINIMUM OF LIKE 5 SECONDS , SO U WOULDNT REALLY LOSE SPEED IF U DO IT RIGHT, UNLESS UR DRIVIN UP HILL AND HOLD THE CLUTCH IN.

AND THE OTHER REPLY I GOT ABOUT THE CAMSHAFT TWISTING IS GOOD INFORMATION TO ME I NEW KNEW ABOUT THAT SO THANKS FOR THE INFO.

It is also a good way to hurt your clutch.

Hmmm, push clutch in and out, in gear, at 3k... okay, I want a ruined clutch!

Seriously, though, this point was tackled a while back. Some guy said that when you are in a race and want to move up, just push the clutch in and out and your car will surge forward. Then the SMART people (AKA moderators) stepped in and said "Whoa, brother, if you do that, prepare to replace your clutch after a couple races."

I think the only time you can do that without hurting the clutch is if you have some big time expensive racing clutch.

As for double clutching... That seems like it would be incredibly difficult to do fast enough (In an unsynchronized transmission) to be of any use. It seems like by the time everything was lined up and ready to go you would have dropped a considerable amount of speed.

granny shifting as i understand it is basically burning the clutch
ie rev it up and let the clutch out real slow

JTEUTON- SORRY FOR THE MISUNDERSTANDING BUT I HAVE A STAGE 3 CLUTCH THAT MY UNCLE AND I PUT IN MY ACCORD, AND I ONLY DOUBLE CLUTCH GEARS 2 AND 3, NOT ANY OTHER ONES, AND IT DOES WORK. I GUESS U WOULD HAVE TO PUT STAGE 3 IN UR CAR AND TRY IT BEFORE U CAN REALLY DAWG IT. BUT EVERYONE ELSE DOES HAVE GOOD POINTS ON HOW IT DESTROYS UR ENGINE AND CLUTCH .

doube clutching does work.. i nomally double clutch first gear jus to get a good jump off the start when i hit 4500rpm. i normally dont gun it off the start so i dont get a lot of wheelspin. the car will pretty much rev so quick u'd have to keep a very close eye on ur tach.. otherwise it'd rev very quick and u'll over rev. i have a stage 1 ACT clutch. double clutching on 2nd and 3rd dont help me very much, but ofcourse it will work for a stage3. yes it will tear up ur flywheel and clutch, but hey. if ur not willing to do it, Y RACE?? :werd: OH and please do tell me how the stage3 feels?? didnt want to spend the money on it, settled for stage1 since i was gettin a motor swap soon anyways.

as stated before, double clutching is used in vehicles with un syncroed trannies. what you guys are doing is not double clutching, it is letting the engine rev up and dropping the clutch halfway through your time in a said gear to give yourself a boost, i guess this could help in a race, i will not dispute that because none of us has any real evidence to prove it. im not disputing if this technique help you win, its just not double clutching, and if thats what the ment in fast and the furious, they were using their terms wrong. mangled jargon of sorts.

an example of double clutching, my friends 1932 fire truck, has no syncros, so to go from first to seccond you put the clutch in, put it in neutral, let the clutch out, estimate rps for entrance of next gear, put clutch in maintaining rpms, and theb put it in 2nd and let the clutch out.

dudes, no reason hear to rip eachothers balls off, just chill.

Everything anyone saw on F&F was fake. It was a cool movie but the people who directed it were retarded when it comes to cars. Notice how the NOS line is full of air when the guy hits it in his RX-7, and you can see the nitrous pushing through the empty line. Wouldn't a 10 sec. car have a purge kit so there was no air in the line? There are MANY others but I just wanted to point out an obscure error. What double clutching really is has already been answered.
What do you guys think of starting a thread to see how many flaws we can find in Fast and Furious?

ok, i didn't read every reply but heres my opinion on "double clutching"

ok, say your racing, and your foot is all the way down on the gas, and you change into, say, 2nd gear, keep your foot all the way down on the gas and change gears as freakin fast as you can. thats what an old dude that races out at the track where i race told me. but it can burn your engine up pretty good if you do it too much.

I think thats called power shifting through the gears. Anyways my 2 cents...I was taught that double clutching is when you rev the engine and match the revs close to what they are going to be when you drop it into that gear....helps save the tranny and clutch or something like that....ie...downshifting to second at 45 to gain speed and you know at 45 that your engine pull 5g's then you push the clutch in ...rev the engine to 5g's and then engage the transmission into second.....anywaz that is what i always thought

I will emphasize the fact that there IS NO REASON to double clutch in our cars. The previous threads are right, our transmissions (manuals) are syncronized transmissions. This double clutching IS NOT good for your transmission. You're putting pre-mature strain on your drivetrain.

And I won't begin on this crap about pushing the clutch in and out really fast. That makes ABSOLOUTELY no sense at all. That has NO physics behind it. It goes against all common physics laws. Think about it. You're disengaging the clutch disc from the flywheel, when you re-engage them (i.e. releasing clutch) you're transmission has slowed down a bit, maybe going at almost the same speed, but your engine, the flywheel, is moving slower. So when you re-engage them, you're taking a slower moving body and throwing it against a faster moving body. NOT GOOD.

How bout we try this experiment. All of those who think this crazy idea works (and want to stand behind it) can do this: while someone is driving a vehicle down your road at 30+ mph/kph, pretend you are the fly wheel, and the road is the clutch plate. Then, while the other person is driving along, you just open your door, and jump out to meet the pavement below. That's the equivalent of what you do with clutch when you're doing this crazy in/out stuff.

what their saying is the engine speeds up before the clutch goes back in and help them or something, whatever, not gonna dispute that. however, i was wondering something about my car, i believe i have my clutch cable adjusted right, its at specs. but if im driving down the road and go to put it into 5th it grinds sometimes, and believe me i have the clutch in, it not much of a grind, just a little crunch, at also does it sometimes in reverse. any ideas.

What is powershifting?? I've heard this term tossed around a bit. There's this mexican guy I know who has a stock '00(i think) mustang with an auto and everyone says he powershifts. Well i was rollin with him once and he manually shifts through the gears with his automatic. i.e. - like starting at 2, going to d3, then d4 on our cars.

i would never suggest double clutching upshifts on gearbox with synchros unless there shot(yes i have done this for exactly that reason) however downshifting is an etirely different story, the primary use for double clutching is to match revs to avoid scratching the synchros and more importantly to avoid upsetting the balance of the car at the limits of adhesion... i would not suggest ever shifting while cornering near the limits of your car but braking is also affected by sloppy shifts and at somepoint you can upset the car even under braking so basically learn to doubleclutch and heal/toe downshifts.. but avoid it with upshifts unless your car grinds upon entering gears(and you don't wanna hear it grind) i often double clutch upshifts in my one friends 86 crx si cause the tranny is shot and i don't like grinding other peoples shit

POWER SHIFTING is when u dont take your foot off the gas and slam the shifter real fast in to the gears... i know that when i red line my car in 1st and power shift to second, it spins for 15 feet adn then accels some more...

Double-clutching was common in older cars and is still common in some modern race cars. In double-clutching, you first push the clutch pedal in once to disengage the engine from the transmission. This takes the pressure off the dog teeth so you can move the collar into neutral. Then you release the clutch pedal and rev the engine to the "right speed." The right speed is the rpm value at which the engine should be running in the next gear. The idea is to get the blue gear of the next gear and the collar rotating at the same speed so that the dog teeth can engage. Then you push the clutch pedal in again and lock the collar into the new gear. At every gear change you have to press and release the clutch twice, hence the name "double-clutching." This from: http://www.howstuffworks.com/transmission2.htm

Sean is right. Double clutching is absolutely REQUIRED for unsynchronized trannys.

However, the posters that say it's useless on a synchronized tranny are missing out on some performance...

The purpose of double-clutching is to match the speed of the engine and the transmission's guts.

What synchronizers do is help speed the guts up, but it takes some time. Have you ever noticed when you go to downshift without a double clutch that you have to push on the shifter for a couple seconds before it snicks into gear? That is because the input shaft of the tranny is turning at the wrong speed for that gear, and the syncros are working to "synchonize" their speeds. When the speeds match, it snicks into gear.

Now, double-clutching allows you to synchronize the gears manually, and is often MUCH MUCH faster than waiting for the synchros to do the job for you.

When you double-clutch, you put the tranny in neutral and let out the clutch. Then you hit the throttle to speed up the transmission input shaft to match the speed that it needs to be for the gear you're planning to select.

Then, you push in the clutch again and go for the new gear.

If you learn to do this fast enough and properly, your downshifts will be VERY smooth without burning on the clutch or waiting on the synchros.

If you're trying to get the fastest downshift on your manual tranny, double-clutching is the way to go.

There is another method called heel-toe, that is VERY similar to double-clutching, but I haven't mastered it yet, because my feet are too big in my Miata to do it properly.

When double-clutching, you have to do it LOONG before a turn that you need to downshift for because you need to complete it before braking. This costs you valuable time. Double-clutching is fine for straght-line performance, since you aren't looking to power out of a turn any time soon (we hope)

However, in twisty situations, such as autocross or road course track racing, a heel-toe is better because it allows you to brake while you're doing a double-clutch, which allows you to carry as much speed as possible into a turn, scrub it off at the last second while selecting the new gear and power out of the turn.

Essentially, you do a double clutch, but you keep your gas foot on the brake and just roll your foot over onto the throttle when you're in the "neutral" phase of the double-clutch.

I use double-clutching all the time to help with smooth downshifting. It avoids the lurch assoiated with selecting another gear, while at the same time avoiding burning on the clutch to avoid the lurch.

Give it a try sometime. It DOES work, and it IS useful. How useful in a 3gee? That may be debatable, since it's not likely that you're gonna be autocrossing any time soon with it. I can't comment personally on what kind of gains you get on a 3gee since mine is an auto, but my other 2 cars are manuals and I *do* drive the piss outta the Miata on a regular basis. FWIW, I double-clutch my Subie regularly as well, but not as often as in the Miata (I'm sure you're not surprised)

I like to think double-clutching and heel-toe are friendlier to the clutch AND passengers.

And it does have a "racy" excitement value too. Is just *feels* fast..because it **IS** fast.

i dunno i think their saying that when u shift regularly the car disengages and goes down in rpm/speed, that's when u experience that "lurching" effect as he called it, then u re-engage the clutch but your starting at a lower rpm/mph and u sorta have to work your back up for that few seconds to actually begin accelerating again, what their trying to say is that when u double clutch (done correctly), when u disengage and then rev in N, your basically trying to match the RPM u left and re-enter that gear without sacrificing power or acceleration.

ok i know i'm not helping by continuing to milk this thread but i just felt like being part of the problem ;)

This Thread is far from over. Double Clutching Alows the Tranny To Speed up faster then the motor. It has nothing to do with Sychronized trannys. When ur shifting, between shifts the tranny slows down , and it gives more ware on the Clutch.

This double clutching alows the Flywheel to spin as much or more then the clutch, So when you drop the clutch at high Rpms there isnt that much difrence in between the two. It Gives less shock to the Tranny and the whole system.

It is True Double clutching was used on old Trannys, When they didnt have Sychros, But there is a plus when using this on new trannys.

here is the exact definition of double clutching from howstuffworks.com: The transmission shown here does not have "synchros" (discussed later in the article), so if you were using this transmission you would have to double-clutch it. Double-clutching was common in older cars and is still common in some modern race cars. In double-clutching, you first push the clutch pedal in once to disengage the engine from the transmission. This takes the pressure off the dog teeth so you can move the collar into neutral. Then you release the clutch pedal and rev the engine to the "right speed." The right speed is the rpm value at which the engine should be running in the next gear. The idea is to get the blue gear of the next gear and the collar rotating at the same speed so that the dog teeth can engage. Then you push the clutch pedal in again and lock the collar into the new gear. At every gear change you have to press and release the clutch twice, hence the name "double-clutching." http://static.howstuffworks.com/gif/trans2.gif Here is the link to the how manuel transmissions work http://auto.howstuffworks.com/transmission.htm pretty much from what i new semi trucks use it because their transmissions are meant to last as long as the motor 500k and with syncros the motor would not last as long because syncros dont tend to last as long as they may need them, so they dont put them in their.So semi truckers would need to double clutch so the gears dont grind. I heard about this on horse power tv.:)

yah, If you can Shift fast enough for it, But you run the Risk Of Crunchin them Synchros. double clutch it if you can, but In Reality, if ur double clutching in racing and you dont do it quick enough your Losing the point. Takes ALOT of Practice, and Grinding. some people dont even want to try, and Just say Screw it. and Dont lift to shift- Thats someone Signiture on here.

My dad showed me how to double clutch. I don't know much about the insides of trannies, but I do know that double clutching is WAY faster than using the synchros. Double clutching is also essential for me to get into first gear if I'm going any faster than 10 km/h. I dunno if that's because my 1st synchros are boogerd, or our cars are just like that.

After I mastered the double clutch, I started working on shifting without the clutch. After lots of grinding, and a few teeth later, I figured it out. It doesn't work to good shifting up, but works perfectly shifting down.

ok i dont want to read all of this thread, but i read the good explanations.. here is something i am not clear on.

is it bad, good or ok, they way i downshift?...

basically going from 3rd to 2nd to go around a corner, i will just put in clutch. rpms naturally fall, so i rev while changing gears, and clutch is still in. and i bring rpms up to the point they will need to be so the car does not lurch. by the time the rpms are up, stick is into the next gear, so i let out the clutch. it works well, and i can do it relatively quickly, and without any lurch or grind. but im sure its not double clutching. is there any point to what i am doing, or should i just let the synchros do all the work for me?

Sounds like you're just rev-matching...that's good since it provides for less wear on clutch.

shouldn't you let the clutch out while your in neutral so that the insides of the tranny get moving? i dunno, maybe there are no insides to be turned while in neutral.

Thats the point of double clutching. And there are insides turning, if ur letting the clutch out but in nutrual and let the Rpms Fall, Ur missing the point of double clutching, You have to Blip the gas to get the Tranny\flywheel Up to speed.

Even if you did do rev matching, basically to the point where you left off, then you engage the clutch by letting go, it still drops dramatically.

IT doesnt drop Dramticly. It would Drop to what ever point its suposed to be at, the point of the Double clutch is so it Doesnt Lurch, Its better to Mesh the fly wheel and Clutch that are spining the same speed Rather then Drasticly difrent Speeds.


You want The flywheel to be spinning fast It helps to keep from Ware on the Clutch.

yeah tru, just like the rev matching but if ya miss it youre probably gonna end up missing the teeth and shoot the gear off, but thats like what 1:1000 chance it will happen. lesser wear on the clutch is better but hope you dont miss it and screw the gears up.

Ur talking about not Disingaging the clutch and just force the gears. This isnt Double clutching.
