If you watched the movie "The Fast and the furious" may sinabi na line si Dominic kay Brian ng natalo niya siya...

What does that mean??

wag ka mag-base sa F&F. madami BS dun sa movie. here's what google said 'bout double-clutching ...

by Jeff Krause
Double-clutching is the proper way to downshift at speed without placing excessive wear on the transmission's synchronizers. This allows you to select a much lower gear without the tell-tale lurch you normally get when the clutch is let out after downshifting.

When downshifting my BMW M5 from 4th gear to 2nd at 50 mph, I need to raise the engine speed from 2200 rpm to 5000. To prevent excessive synchroniser wear, the clutch is depressed and the shifter is moved to neutral. The clutch is then released, and the gas is depressed to bring the engine speed up to where it needs to be for the lower gear. The clutch is then depressed again and the shift lever moved into the lower gear. When the clutch is released the second time, the engine is already turning the proper speed . While this sounds complicated, it's easier done than said, and only takes about a second.

On those vehicles without synchros, double clutching is done to allow changing of gears (especially downshifting) without grinding or otherwise stressing the transmission.

the phrase used in that movie was wrong...double clutching in a drag race?!

This is why this movie was a big joke in the US of A. Double clutching is for down-shifting. Now, why would you wanna down-shift on a drag race?!

Granny shifting, is simply shifting too slow and makes the engine bog down.

Granny= grandmother or father, lolo or lola.

If you really need to downshift from 5th to 3rd at high speed, simply rev-match. Rev-match is the same explanation of double-clutching. I do rev-match often when exiting or entering a turn, para easier to keep the speed up and less tranny stress.

edit: same link pala ng kay ronin yung na post kong una..hehe

not to mention how amazing it is that an integra and a civic BARELY lost to a twin-turbo, nitrous equipped rx-7 and a "turbo" eclipse with nitrous and $10k in turbo upgrades ("turbo" is in quotation marks because they actually used a n/a eclipse in the movie, stock drum brakes and all)

i also noticed that they raced with the windows down.. talk about "drag" racing, this creates so much drag on the car!

i agree the fast n the furious movie is full of BS, pero i know there really is a double clutching in drag racing, lalo na sa illegal style. parang cheat technique para mas may sipa pag nag shift gear.

cguro the "double clutching" used in drag should have had gotten a different name, hehe

yung need for speed underground nga ginaya sobra yung drag race ng F&F
