"Flat-changing?"

[red s2000]

Occasionally (mostly when dragging stoopid skylines) i find that flat-changing is much more useful to get the jump on the ball-breaking turbos.
Only problem is that i get a really bad crunching sound if I'm on or beyond the red-line (9+). Sometimes the revs spike as well, I'm thinking this is bad...just wondering if anyone can tell me the quickest way to change gears under extreme load...

[wynode]

Quickest way = flat changing........but like you said, if you get it wrong, then you can have gearbox troubles in the not to distant future :)

That poor poor AP1!! :?

I'd be too scared to flatshift, I mean the revs still have to drop 1000RPM to get into the next gear :S and your kicking the revs up even more :S

What you mean??

Why do the revs have to drop? The only thing that flat shifting is bad for is the g'box and probably other drive train components because of the sudden shock... but mainly g'box. If the engine can sustain potential damage from flatshifting, I doubt it has anything to do with situation of revs during a flatshift.

Thoughts?

To the best of my understanding too - "flat-shifting" is incredibly silly for your drivetrain - the tremendous shock it puts upon your transmission is just not worth it !

Ofcourse , you could go the next level , and shift without use of clutch ala superbike styles...but one or another you will soon reap the benefits of fecked tranny !

Dont do it people ! BAD !

[SPEEDCORE]

Hold on I know you where commming from know SIKCIV......

I was getting confused thinking flat shifting was shifting without use of clutch.....

My view is if you are good enough you can shift quick enough and get back on the gas so quickly that the revs will not drop significantly.

Sorry for the confusion.

[SIKCVC]

yeah :P shifting without a clutch would be the way to go, but its a bit of work to get used to and to do it fast :P especially in the high revs.

The reason i wouldn't flatshift is because when you shift gears, in order to get into the next gear the revs must drop, and your doing the complete oposite. Thats what i ment :P but I didn't explain myself very clear :?

trying to drive a s2k like it has sequential now hahahah

[Kit]

as said before. flatchanging is really bad for your drivetrain.
so try not to do it unless beating the skyline is worth more than a few grand (to rebuild your gearbox) hehe :)

[McChook]

Just go buy a Pfitzer doggie...
flat change problem solved....

[ECU-MAN]

like you guys said flat changing is bad. crunching is very bad..

the input shaft and output shaft of the gearbox have to match in speed before a gear change can occur, when you put the clutch in the input shaft is disconnected from the flywheel, when you engage a gear the syncro's have to slow the input shaft to match the output shaft revolutions. when you flat change your input shaft is being driven by the flywheel partly and you are making the syncro slow the output shaft ( eg the whole car ) to match the input shaft and then the gear goes in. worse when you change with out the clutch. anyway thats what tafe lecturers tell ya , poor syncros are only made of brass, but have to do soo much work :(

just wondering... how the hell do u change without the clutch?

[joyride]

just wondering... how the hell do u change without the clutch?auto gearbox

Easy just pull it out of whatever gear you are in and ram it into the one you want..... brute force is all it takes.

Your gearbox will love it....................... no seriously!!! :roll:

[civicboy]

ahahaha all i can say is 'love your car'

brute force is one way, but when your driving, when its time to shift ,back off a little ( help the gear come out ) then slowly pull to neutral then hold towards the next gear, apply gental pressure towards the next gear and when the revs are right in she goes. shifting up is piss easy shiffting down is a little tricky but easy when your good at it.

CAREFULL YOU DONT CRASH TRYING THIS SHIT. no one hear takes responsibility in you ****ing up your gear box or pranging your car or getting addicted to clutchless gear changes.

[SPEEDCORE]

Thank you ECU........ and that boys and girls is the way to get home when something has ****ed up with the clutch and engaging it is not possible.

[ECU-MAN]

yeah I have driven a car back to civilization with no clutch after all th fluid leaked out of the clutch master cylinder in the middle of know where, good fun when its not your car.

[McChook]

I learnt *clutchless changes* the hard way

In my Rover 416i, my clutch cable broke TWICE... and the first time, I had to drive it for 3 days with no clutch...... I was a MASTER... just couldn't get into into 5th, was afraid it might cause the box to fall out....

[MRVTEC]

i flatchange gears in my car when racing its not a matter of missing gears or crunching, you have to know ur cars potential and what kind of box u have. if u have a short shift kit and u flat change its the best. i love flatchanging especially when going from 2nd to 3rd gears its the best feeling

How did you get it into first if at standstill ? :|

[majic777]

one way is to flatchange into the next gear a millisecond before it hits rev limiter, then revs don't shoot up any higher than they already are... also can be useful in some turbo cars! don't loose boost between gears :) can reduce clutch/drivetrain life of course tho

flat changing is for people who dont know how to change quick

you let the car roll to a top in neutral and turn the engine off. you then pu tit in 1st and crank da engine to get going. I know its not the best thing for you starter but it will get you out of a jam.

If your car is f*cked, the starter motor is enough to get you up a curb and off the road in most cases.

lol

Flat Changing is quicker than any change done using a clutch.

[sesshoumaru]

it's not necessarily quicker or slower.

all it means is that the revs don't drop as much.

[Hondavirgin]

a quick change using the clutch can be done in less than a second anyways, and so i don't see how flat shifting manages to stop the revs dropping more than a normal fast change......, unless you are taking so long with the clutch in that the revs drop past what they will be at when the gears engage.

i thought the car will have to be at a certain rpm for a certain road speed?

correct me if i'm wrong.
