You don't need to double shift when upshifting...

 

They've been watching too much Fast and Furious methinks! Don't worry, you probably haven't done any harm to your car

 

Yeah, fast and furious, LOL. DOuble clutch like a real driver hahahahhah

 

double cltuching is a waste of time when upshifting; and you really don't need to do it when down shifting (aka rev matching). This trick for quick shifting is really simple, have your hand with slight tention on the stick ready to go into the next gear, release the gas and slam the clutch down until it's all the way open. And then almost simutaneously (but not quite, clutch really needs to be fully engaged) throw the stick into the next gear, and almost miliseconds before it's all the way in start releasing the clutch and let it grab the gear and throw the gas back on. You should eventually get it down to where your taking less than half a second to be in the next gear, and every shift will be pretty damn smooth. It just takes practice, it's a lot faster and easier to change gears normally than worrying about all this double-clutching nonsense,(wich like said above is a term used wrong in "fastandthefurious") just keep doing it until it's like one quick solid movement. Hope I helped, just keep practicing. anybody feel free to critisize me if I sound wrong, the more critisizem, the more I learn. Sorry I typed suck a long comment.

 

DJ, what you are talking about is rev-matching, not double clutching. Double clutching is largely unnecessary on modern cars. It is used on vehicles that to not have synchronizers in the gearbox. Pretty much every car manufactured in the last few decades has synchros. For those vehicles that do require double clutching, it goes like this:

-clutch in (disengaged)

-shift lever to neutral

-clutch out (engaged)

-clutch in

-shift to next gear (up or down, depending on whether you are accelerating or decelerating)

-clutch out

But it's a huge waste of time on synchronized trannies.

 

This in one of those issues that will never be resolved! Double clutching! gawd! Upshifts, downshifts, rev matching...
Basically, no need to do it with a modern car. But do rev match when downshifting. Which requires you to clutch in/out twice. That's how it gets confused with the double clutching of the 50's British roadster definition.

 

Anyone heard of Triple Clutch? How about Quadruple clutch with your right foot and triple shift with your left hand while being free living your life a quarter mile at a time in that 10 seconds?
This is the new theme in F and F Part II.

 

yeah, I agree, I just always grew up calling double clutching when you downshift rev-matching. But that is what I was saying, all of that is unnessasary, I was just trying to help him out by talking him through the process of normal shifting to make his shift faster since he was having trouble with that

?!?! Rev matching does not require double clutching! Rev matching does not even necessarily require heel-toe.

Oh good golly the amount of posts/confusion about these dang foot work/tranny work topics..

 

I thought rev-matching was when you blip the throttle to match the revs to the gear you want to shift to....thus, the term "rev-matching".

I'm confused.

 

No, you have the right idea. What I do when I downshift is:

- disengage clutch

- downshift to the lower gear

- blip throttle

-engage clutch

The timing for this manuver is pretty tight, SO BE CAREFUL! If you screw up, you can seriously damage your clutch and/or transmission!

I tend to downshift pretty aggressively anyway. It's an old habit from my truck-drivin' days.
