double clutching
Alright, i searched for this and i didnt find anything except for the discussion on autos, so, Is it bad for your car to do it, does it actually make a difference in speed in our cars, and also how exactly do you do it? I read the explanation on the "this is how your transmission works" site, and i didnt understand all the way. Somebody please give a complete explanation, thanks.

Rep Power: 0 It's when you shift down rev it up and then switch up gears so you're on a higher gear with a higher rpm giving more output. My buddy did it in his 84 shorocco from 1st and the start was fast!

Rep Power: 0 simple:
When you shift you depress the clutch pedal to disengage the clutch from the flywheel, meaning the engine is disconnected from the transmission. Now, if you are moving, the inside of the transmission is still connected to the drive wheels, so the gears inside are still spinning. When you shift gears, you are connecting one "piece" of the transmission to another "piece." These "pieces" arent always spinning the correct speed, so a syncro spins one "piece" up to nearly match the speed of the other "piece" allowing them to mesh together and lock in place. When you let off the clutch and the clutch disc re-engages the flywheel, the engine is reconnected to the drivetrain and power moves through the transmission to the wheels.
Synchros in our cars are good and new, like most modern transmissions. Try this... When its quiet out drive at 30 mph. shift into neutral. coast for 30 seconds, then Depress and hold the clutch pedal and slowly move the shifter into 1st gear. Listen to the transmission make a "whirrrrrrRRRR" sound, thats the "piece" of your transmission thats connected the the input shaft syncing with the "piece" connected to the driveshafts.
Old synchros couldn't do this. So, you would depress the pedal, shift out of gear, release the pedal (thus spinning the "piece" connected to the input shaft up to engine speed while the "pieces" are disconnected), then you depress the pedal again and shift into the next gear. When you double clutch you are spinning one "piece" up to speed so it lessens the workload on the synchro.
There are no real performance gains, it takes more time to do, and its a movie myth.
I'm still sick with a sinus infection so its tough for me to concentrate and explain. Sorry
edit: well there are special applications for double clutching, but not a 2k1 civic, or the majority of cars from about 66 and on.....

Rep Power: 0 << If your in the bay area, I'll show you how to double clutch. All the ppl who say its a bunch of bull say it is cuz they don't know how to do it!!! Sure it works. >>
I have a class A license and have Semi Truck Training. I KNOW how to double clutch, and its not some WOW-WEE super performance gain. There IS NO gain. It takes longer to shift. If your transmission needs it, you do it. Many high end racing transmissions need it. But no way in hell that big bad honda of yours needs it.
