"Granny shifting, not double clutching like you should..."

Quote from The Fast and The Furious.

Question is,

What is double clutching please?

old car thing, bus drivers used to have to do it, but basically its putting the car into N before selecting the next gear. They say if you have a really power car you should do it to make sure the gear stuff works right.

Why thank you.

i thought double clutching was when you have your foot on the accelerator and at the same time you put the clutch in then out and you catapult forwards??? am i wrong???

i dont know - for i do not have a clutch

Yeah just realised he was in a Skyline when Vin Diesel tells him.... They aint that old.

Is Al right?

it wasnt a skyline mate it was actually a mitsubishi eclipse

I stand corrected mate, I aint watched them that much

double declutching involves a shift out of gear, clutch up in neutral, blip throttle, clutch in, select next gear clutch out. (i believe it ensures the main gearbox input shaft continues to spin, so that the gears can mesh properly)

no car has ever really needed to use the process on upshifts, but older cars without synchro used to have to on downshift.

in a drag race, you REALLY dont want to be double declutching you would finish about a minute after the other guy

(it is nice to do it on downshifts though..i do though i dont have to at all, as it sounds good )

I stand corrected mate, I aint watched them that much

hehe so was you focussing on vin diesel the whole time?

im sure double clutching is just "slipping the clutch" twice.

used to do it all th time in my old RsT .,

bikers do it all the time.

not really, see post above

that is whats known as slipping the clutch and even though it might fell good coz you get a sudden boost its not good for the clutch and any way you own a supra you shouldnt need to do that to get a boost

The best use of double declutching in a film was Steve McQueen driving the Mustang during the chase in Bullet. Sounds awesome on a V8

Cigar for the man here, nail has been hit so completely upon its little head as to defy the requirement for furthrer postulation on the subject

Will have to watch it then....

IMHO Double de-clutching is only really useful on down-shifting and really only worth doing when you are using toe-and-heel.

I used to have great fun in my old Focus doing this.... then I grew up and bought the Supra .... which doesn't have a clutch.

You only really have to double declutch on a non-synchro box, which would be something over 40 years old now!...

Modern cars driven briskly can benefit from what used to be called, "gassing-in-the-gears" on the downshift, which is -press the clutch pedal, out of (say fourth) gear, gas the revs up a bit as you go through neutral, keep the revs up as you put it in third, let the clutch out with the revs still up.

You will find the car transitions into third (or any gear) much more smoothly, and it sounds good too.

I think you will find this is what bikers do (I used to do it on mine anyway)...........

It stops that engine braking lurch you get when changing down...

very satisfying when you can heel-and-toe correctly on downchanges, cant do it in my soop for obvious reasons.

may need an empty road for trying this out

oh isnt it true that you dont need the clutch if you get the engine speed bang on?

yes its perfectly true, but dont try it on the Supra - buy an old fiesta!

i used to have a 1.6 16v Fiesta when i was a lad, 2 times the clutch cable snapped and 3 times i drove back from Nottingham to Sheffield clutch free - thanks to my old driving instructor and my dad teachin me how

I've had the same with my A-Team van. Easy to drive without a clutch untill you have to stop. Lol

Wouldn't dream of trying it in my Sup though.

At first it is easier to do if you are changing down to overtake someone, i.e. you are not having to slow down or use the brake at the same time (when you would need to be heel-and-toeing).....

It sounds very purposeful to the guy you are about to overtake too. They will know your intentions clear as crystal......
