Re:double clutching?
let's all just calm the ---- down.
I didn't say "double clutching is the ---- because it makes you go really fast" I was asking to confirm what I thought it was and to see if it had any affect on how fast you go. I have learned that it shouldn't be used unless you are driving a big truck with no syncros and that you all love the fast and the furious.
I'm sorry to all those who were offended by what I have said.

Re:double clutching?
For all you ------- idiots(DJ DIGITZ and random-strike) who think "speed shifting" is not letting off the gas when shifting is ------- wrong. Get your ------- facts straight before you go blabing your ------- mouths. I believe that is called Power Shifting. Here's a little lesson for F&F super streetracing wanna-be's...
Power Shifting:
The gas pedal goes to the floor and stays there- never lift off during shift. Preload the stick by pulling on it before you reach your shift point. At the pivotal moment simultaneously tap the clutch pedal and slam the stick into the next gear. Time it right and you will see the rpms climb 200 to 500 rpm between gears and feel a strong surge as the next gear engages. This doesn't not necessarily give you more hp but means you are better at shifting then most and could matter in a race between winning and losing or possibly better quater mile times.
Now for speed shifting...
Speed Shifting for morons:
What you do is shift without using the clutch before shifting matched the engine rpm before shifting into gear but doesn't matter when shifting out of gear.
What this does is match the input shaft speed to the
gear, assuming you know your gears they slip right together.
But ofcourse you guys know everything and i'm a ------- idiot. Maybe you guys should go watch F&F on more lame streetracing wanna-be's slang. I hope you go faster with your speed shifting.

Re:double clutching?
or you could just wait for the fuel cut to shut the engine off, then bang it into the next gear as the revs are falling. indycars use an ignition based version of this for their "no lift shifting" system. same with motorcycles and shifterkarts. but those are all sequential gearboxes.
double clutching is something that is only necessary while downshifting dog-engagement gearboxes. i believe most big trucks even have synchros now.
while it's not NECESSARY to double clutch a synchromesh gearbox on the downshift, it IS faster if you decide to row through the gears instead of skipping. it also doens't wear the synchros as fast. and it's fun. that's why i do it. i had to learn to drive the dogboxes on F2000 cars, so i practice in my street car.
speed shifting and power shifting may help in a drag race, but in a road race you would never see the finish line..

Re:double clutching?
LOL, everyone here just needs to shut there mouths. This is a very very stupid thread it should be LOCKED!!
The question was asked does double-clutching help??
NO IT DOESNT. God invented a little thing called the SYNCRO. So gears dont grind. Thats it! thats all you had to say to answer the question! If you want to learn more goto www.howstuffworks.com

Re:double clutching?
i use to double clutch my og *** accord, the "SYNCRO" was fucked and the tranny was leaking, super beater! but the only was to get into gear is to pump the clutch, shifter to neutral, let go clutch, then clutch back in, to select a gear.
while you guys argue about the speed shifting and powershifting, it doesn't do you any good in the quarter mile. Try blasting through the 1/4 mile and powershift the second gear, you'll yeild bad 1/8th times for your lost of TRACTION, anytime lost of traction occur you will have weak *** 1/4s times.
power shifting or speed shifting may help people with slicks, but not with people who has 300+ tq (torque kills not hp) and don't want to break their weak trannys would do no good.
plus the grinding part while speed shifting will hurt the times, i shift this way "clutch in HALF way (catch point) and shift" instead of clutch in all the way..
only way speed shifting would help you in a race is road race, where you can hang on to a certain rpm, and speed shift w/o grinding. (you can't speed shift AT ANY RPM, only certain rpms where you trannys allow [ means you better know your car )
