How Do You Shift?

[lingeringsoul]

Friend said she dragged Mr. XXX and XXX was granny shifting or what ever crap that is and she won etc etc blah lbah..... Since I have no interest in dragging anyone nor have I tried, is there a difference in the way you shift gears when you are dragging? Basically, I just wanna know how mnay ways you can shift.

i shift like the wind! :lol:

hahahahahah okay well this girl you know has watched the fast and the furious to many times hahah

number 1 - Never take lessons from the fast and the furious

number 2 - Never take lessons from the fast and the furious!

Number 3 - Repeat steps one and two.

but anyhow double clutching is a form of shifting thats used on cars that have no syncros, seeings though all modern cars have syncros, double clutching is not necessary.

Sometimes double clutching is good whilst shifting down, to get into a gear. Youll Find that in some cases when a car is cold shifting down into 2nd can be hard therefore the use of double clutching is used to help it get into gear.

The term "granny shifting" is just used to insult someone on how they change gears.

In terms of dragging, I can gaurantee that none of the professional fellas (or anyone who knows how to drive) double clutch. Double clutching takes time, time is precious over a 1/4 mile.

get it?

Shifting normal - clutch-change gear-release clutch

Double Clutching - Clutch in - put into nuetral/blip throttle/disengage clutch - Clutch in - change into gear - clutch out.

or if you have a dog box i believe you can flat shift... ie dont use the clutch and jam it straight in

EDIT: left the 'f' out of shift

so basically, all drag racing involves normal shifting throught the gears? nothing fancy?

umm flat shifting is not shifting like that infact shifting like that is a bad idea and doesnt really work in a racing sense

flat shifting = keeping the go pedal on the floor while changing gear giving that short time to raise revs whilst changing

the reason this is usually only done with dog boxes and such is cause its VERY mean to the box i.e. standard box just breaks and cries and you dont want that

it is even bad for the engine in worst case scenarios (if you miss the gear, engine revs up and boom! nice little shower of what used to be engine internals)

and as for shifting in a drag it is basically finding the best for your car

Example: Skyline GTR(with standard box) a medium speed shift is the best because syncros in box cant handle full rev fast changes (reason why standard boxes always have stoofed syncros)

also rev limiter changes arent always the best either (again with GTR) if your setup is making peak power at say 6500rpm then the key is to keep the revs around that number too high not making as much power as you could (power curve drops off) too low takes too long to get onto best power

*end rant*

if i have unanswered anything tell me and ill have a go

From what i understand, Flat shifting is basically as u guys said above, shifting while holding the throttle wide open.

Ive been told and believe that is it bad for pretty well any gearbox because it shock-loads the gears on the main shaft against the gears on the cluster shaft because as the clutch is let out, it smacks the input shaft gears against the other gears at the gearbox tries to catch up with the amount of revs the engine is doing. Instead of having them at a reletivly constant speed as u do when u letter the throttle off as u change gears.

Im not 100% sure if thats correct or even makes sence. so correct me if need be.

i flat shift in my pajero.. it loves it, and besides its always on boost then eh,

[Guest Mashrock]

p.s. the syncros love it. soon they will be non existant and i shall have f**ked box..

[Archie@]

Vin Diesel dosn't granny shift.... so neither should YOoo!!

[croat]

haha. Remember "its not how you stand by your car its how you race your car"

[Ruffels]

haha in my old rwd mazda 626 i used to not only keep the pedal to the metal... but also not use the clutch... just jam it as hard inot the next gear as i could hahah... allthough when i missed it really sent a jolt back through my arm ahaha

spose thats how you expect to treat a car worth $slab of beer

yeah similar story in the pajero.. i beleive it will b reak soon. but its all this rain and wet weather making me drive crazy as its the only way it will break traction.

"man, you guyz should be going to mrit or something.."

[Leewah]

Totally agree with what RellikZephyr said.

If you got a really old car without synchros, GET ONE!

If you got a dogbox, SLAM IT and SLAM IT HARD while keeping the foot planted throught the firewall!

Basically, in regards to the shift itself, as fast as you can without breaking the box. On average between clutching, changing gear and engaging the clutch again will take bout .5-.7 of a second. A straight cut shift will take between .4 and .6 depending on how hard you do it and in drag racing, that's a fair bit of time after 3 changes.

How do i shift when drag racing?.....most of the time i use the gearstick...sometimes i may even use the clutch too!!

Just flat shift and every 3 months you can "order new gearbox and ship overnight from Japan".

My Pajero loved it :lol: However... Some thing came out the side of my Barina box when I did it too much

P.s, this thread needs pics.
