So does anybody know how to double clutch exactly. cuz I've heard a couple ways to do it but i don't notice a different when i upshift. but i notice a difference when down shift. does it really help. by the way fast and the furious is the most unrealistic movie i have ever seen. so thats not why i'm asking.

 

It's only for downshifting - F&F is extremely gay and you should be ashamed of yourself for asking.

 

double clutching is simple.

clutch in
put shifter in neutral
clutch out
clutch in
put shifter in gear
clutch out

easy process, but it takes a while to get used to.

 

false

when upshifting, for instance in an awd car that gets amazing traction & had a bunch of power, when you dump the clutch & it grabs as well as all 4 tires grab & the motor nearly falls on it's face due to the resistance, you could stay on the gas & depress the clutch petal for a split sec & let back off of it to pick the motor back up & pull harder..

this abuses the shit out of a clutch so i wouldn't recommend it unless you have a monster clutch in your car & don't mind brakeing things coz with this type of abuse, you Will brake shit.

nothing against the cars i've used in my example.. it was just an example.

 

I've always heard that double-clutching doesn't do anything for a car with syncros.

I believe what Joe is describing is called rev-matching. It helps put less strain on your tranny.

 

no where in my post did it say to press the gas pedal. you're right because it isnt neseccary if your tranny has synchros, unless one is about to bite the dust then you can double clutch to put less stress on it.

 

i'm still thinkin i'm right on this..

joe, i'm not seeing how your description would make the car pull any harder.. why move the shifter if you didn't have to....

 

If you drive stick all or most of your life, you are not supposed to "get used" to the process you've just mentioned. When you do that sequence you will create a sense of pushing forward. It will grab, jiggle then thrust. You can eliminate that by having the gas paddle almost all the way when you release the clutch to compensate, bring the engine up to the existing speed, and exceeding it.

I "double clutch" almost every day unintentionally??? and most of you stick shifters do it as well!!! I explain. Ever happen to you that you're approaching a red light in, say, 3rd gear, without using brake engine( ie; without downshifting to reduce your speed) you shift to neutral and and prepare to hit the brake. BUT before even you touch the brake, within a split second, the light turns back green! What do you do? If your speed still falls in 3 rd gear ( and it should) and if your rpm is high, not quite but almost flirting with 4 gear? You will try to compensate by pushing the gas a little deeper so that when you release the clutch it won't grab and jiggle. Basically try to meet the engine at the existing speed and if you achieve that, the transition will feel smooth.

 

i was just simply stating how to double clutch, i wasnt in any way saying it had any advantages. the only cars that ive had have been MT.

 

It doesn't make the car pull any harder. It's for downshifting only, to smooth shifts.

And as I said before, if the OP could only use the search button, he could have found out without making another useless thread.
