granny shifting?
ok ok..
i just got my civic.. and one thing i hate is when people tell me..
'do you want to be in fast and the furious'
no
but just curious what
vin diesel was talking about when he said
"granny shifting... not double clutching like you should'
can anyone describe double clutching?

Rep Power: 0 Double clutching is only needed for cars without syncros and big rigs. It is completely pointless in any car newer then like early 1980's and it will actually slow you down when racing. Normally you just put the clutch in and shift from gear to gear. Well, this is what double clutching is. You engage the clutch and put it in neutral then disengage the clutch. Then you engage the clutch again and put it in gear. After you put it in gear you disengage the clutch. That is double clutching.

Rep Power: 0 rule #1 you won't learn $hit from either Fast and Furious movie.
rule #2 99.99% of everything you heard or saw on that movie is BS, so forget you ever heard it.
more appropriate questions would be .......
How do I properly launch my car?
Whats the best RPM to shift at?
whats the best shifting technique?
etc...........

In theory, if your gears are done right... shift at max HP and you should fall to max torque.
Ideally, shift at 6200, it should fall to 5500.
BUT since the power curve in a Honda is so top end biased, you're probably better off redlining it out or coming close to it. Even though it starts to drop off, its still higher than if you let the revs fall too far.

Rep Power: 304 Double cluthing is done by truckers since there transmissions don't have syncros. You also might have seen that on older race cars who also didn't have syncros.
They first clutch in, shift to neutral clutch out, then clutch out and clutch in in a higher gear. They manually synchonize.
On down shifts they double de-clutch
clutch in, shift to neutral, clutch out, rev tby blipping the throttle to match the revs to what they would be in the lower gear, then clutch in and shift into the lower gear as soon as the revs drop into the exact place where they should be for that gear and speed. They don't have syncros so they need to do that.

Rep Power: 304 Most people who have transmissions with synchors, on downshifts will clutch in blip the throttle to the revs the engine would be at in the lower gear(rev-match) and directly switch to the lower gear then let the clutch out. Now there is heel-toe, which results from applying the brake while the clutch is in and blipping the throttle with the same foot that is braking, and then switching to the lower gear and letting the clutch out.
their are few clips on www.ehow.com about double-clutching. some guy demostrates it in his bmw m5.

I don't know if you are just mocking the guy who said which questions would be best, but if you are serious, it all depends on what kind of car you are in and what gear and what speed you are at. If you are racing a civic ( stock ), take it all the way to redline in every gear, if you actually have some power ( torgue ) you should maybe only take it 1500 below redline in first to avoid wheel hop when downshifting to second, then take it all the way in the rest of your gears. Wheel hop robs you of traction and time in racing.
This is to the person who asked what rpm was best to shift at

GRANNY SHIFTING--- is when you shift slow and or miss a gear, and letting of the clutch too soon before you actually put higher RPM to the point where there's more forward force, than the wheel pushing force to the engine to level the RPM from the lower gear RPM... which causes the wheel to hinder for a split second and turn again...

How do you know that?

Rep Power: 0 What's really funny about this whole thing is that Vin Diesel said that after their high-speed street race, which was basically a drag race (no turns, no maneuvering). There would be no call for downshifting and therefore no reason to double clutch in the first place. The line makes no sense. It was written by a screenwriter with no racing experience (or manual transmission driving experience, it seems).
There is a reason to double clutch even if you have a new car with synchromesh. First of all, it helps to avoid wearing down the synchromesh, but it also gives you a smoother ride. Why?
The idea behind double clutching is very simple. You are trying to make sure that when the clutch is engaged, the RPMs of the engine output and the RPMs of the transmission input mechanism are the same.
If they are not the same, as you slowly engage the clutch, your synchromesh will start to touch and "spin up" or "spin down" the engine output or the transmission parts. When the transmission parts' rotations are forcefully changed, it changes your speed. That's why you lurch. (Your wheels and your transmission parts are always connected!)
In big rig trucks (and some tractors) without a synchromesh, if you try to engage the engine output to the transmission input gears (dogtooth gears), and they are each spinning at different speeds, you will begin to grind down the teeth. That's bad news, which is why the synchromesh was invented.
So, how do you double clutch? It's actually really easy, and I find it to be a tremendously satisfying thing to pull off correctly, as uneccesary as it may be. When I'm coasting, I like to take my car out of gear and just roll along in neutral. If you have done this, you know that lurch you get when you put it back in gear. This is because while the car was in neutral, the engine spun down to idle while the transmission continued to spin (it's connected to the wheels, remember?)
So, to avoid the lurch, just "blip" the engine before you put it in gear. To do this you must gauge how fast you are traveling (there is a handy meter on your dashboard for this) and what your RPMs ought to be for the gear you want to be in.
Let's say you're rolling along at 40mph. That's probably between 2 and 3,000 RPMs in 5th gear (you don't have to be exact, you DO have a synchromesh, so you can't really harm anything). Tap the throttle to bring the tach up to 2-3,000 RPMs, and then throw it into 5th. You should have little or no lurch.
The less lurch, the better job you've done! Try it while shifting to lower gears, too! Shift into neutral, release the clutch, blip the engine, and then shift into the lower gear.
Phew. I was bored enough at work to write all that, so I hope someone finds it useful.
