Double Clutching

[My 89 Accord Lxi]

Anyone know what it is someone was trying to tell me to do it hen i race but i dont know what it is?

[MyGarbageLXi]

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.

so...what kinda tranny does the accord have? will it help?

[Accord7SE_i]

You got that off of fast and the furiuse dont lie. the guy is right. i ask a trans man about it.

[Sean]

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.

slammedlx this does work but its messes up ur car. i had a friend who did this alot in his bettle and it twisted his cam shaft and messed his car up alot

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???

[SLAMMEDLX]

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.

[87DXHatch]

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.

How did me manage 12 replies to this topic? The first two were spot on

k im a fucking idiot. *puts the i a fucking idiot hat on*

but wtf is granny shifting? Ive heard this term 400 times and im not exacly sure what that is. But at least im hont and admit that i dont know what that exacly reffers to. is it letting go off the gas between shifts? i drive and automatic. k well let the flaming begin

and what the fuck? does wtf stand for??? (joke)

[pimp86LX]

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

i could be wrong i dunno
:smokin:

[SLAMMEDLX]

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 .

[wickedaccord]

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?? 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.

[jteuton]

i guess i'm stuck with this stupid torque convertor piece of shit. I'll be sure to try it out on my friends car though..hehehe

[monsonhonda]

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?

[pimp86LX]

if your into motorcycles double clutching is SOOO usefull for downshifting, ohya...yah F&F was a neat movie but totally unrealistic to anyone familiar with cars..i hate to say it, but all it did was spawn a new and dumber breed of ricer

You are so right about buth F&F and motercycles when I was first learning to ride I almost threw my self off the bike downshifting BTW 82 Honda Magna V45 750

[pimp86LX]

heh heh i have a cb550 and i was racing my bud on his maxim 440 twin...gee guess who won.. only one thing, he has better brakes...crap!! downshift downshift!! ERRRRRRRRR smash

tee hee. the bike was ok just some scratches...i on the other hand I healed up quite nicely..after a while

"chicks dig scars"

ps (cb550)-> 1974 Honda CB550 (553cc) Inline 4cyl, 4 carbs, 22,000original miles, this thing FLIES!!

My dad is thinking of getting a valkery or a new VTX while my mom wants to stop buying american and get a honda pilot that would mean 5 honda's in the family and one TRD Solara.
