Is it different for every car out the or is there a text book way of getting a car off the line as quick as poss?

I'm talking about 0-60 runs or 1/4 mile launches?

One thing I've noticed is giving it full beans is shit and just ends you in a big wheel spin but not enough gas will bog you down.

Odd post I know but let's hear your thoughts.

it differs car to car but in general you want to start with some revs and then ballance the clutch and throttle. on lower powered cars you'll be fine with dumping the clutch and not being agressive with the throttle but some higher powered cars you will have to slip the clutch a bit.

giving it loads, dumping the clutch and flooring the throttle is the slowest way of getting off the line.

I'd say build up a few revs. Find the biting point of the clutch, once the car starts to move floor it whilst slowly releasing the clutch as you go. Not gonna do your clutch any favours but at least you wont lose anything through wheel spin and having the revs up wont bog down the car.

seems to work for this guy!

well he's got something most dont have.....fuck off huge grippy as fuck drag tyres so he's got all the grip in the world to play with!!

Differs for different cars.

For my car FWD Focus 1.8 Zetec mild/high powered N/A screamer best launches I do are build revs up to 2800-3000rpm, off the clutch and usually I get a bit of wheelspin but it kills off very quickly and I'm off. At the Pod I've gotten off faster than a blobeye WRX STi, E36 328i and a Chevy. Different story about 100ft later though Is a fine balance between getting it right because I've span up right through first before. You want just enough power to get a little wheel spin and to kill off instantly and just get grip. Will be harder for turbocharged vehicles though. What I find in a turbo'd vehicle is to use the same method but when you dump the clutch feather the throttle in till you can feel the car gaining forward momentum then nailing it but in doing so I've done both scenarios of still getting wheelspin and dropping off the boost so moral of the story is really learn your car's optimum launch point.

in my fez i launch @1500rpm on half throttle then once rolling foot down and hold on! Works well for me.

my saff has to be 4.5k+ and pretty much sidestep it, anything else and it just bogs!

Altratz

my 4x4 saph build it to 4.5 to 5k then ease the clutch out get it rolling then give it the beans has got me 4.4 0-60mph so far still room to improve i think lol

I generally;

1. Select second gear
2. Press the button that says "launch" on my steering wheel
3. Hold full throttle for about 5 seconds
4. ECU holds revs to about 5500 until I see about 1 bar of boost
5. Drop the clutch holding on for dear life and pulling gears in as the shift lights flash in my face!

There is sometime a step 6 and 7 too.....

6. Remove broken diff
7. Fit unbroken diff

Use acc pedal as countdown-5 rev 4 rev 3 rev 2 rev 1 rev(keeping revs up) then lift of clutch->>>>>>>>>>>>>>>> on to the next control!!!!!!!!!!!!

that one cracked me up too

FredElliot

Press "LC".
Foot on brake.
Other foot to floor on accelerator
select 1st.
Take foot off brake pedal.

After about 5 or 6 goes, buy new clutch

Lots and lots of practice is the only way to master it, it's easy enough to explain the theory but every car is different and you will never be able to explain 'feel' accurately. Even my 1.8 and 2.0 Focuses are different in the way they launch.

what sort of 1/4 miles.60 ft's do u do? i really wanna get a rough idea of my 0-60!

turnover

in a 4x4 saph you should be 1.6s

WongRS

1.7's mine is 60ft.

Heres my launch - running here with 310bhp & 345Ib/ft

Balance the clutch and throttle to minimise wheelspin (result was a 5.7 to 60mph)

i find in ma fez best thing to do is rev limiter it and dump da cluch then you proper feel it snap ya neck bak and is the fastest way to do it ma m8 timed it 6.4 seconds 0-60 thats without a burnout aswel so wud be kwiker with one

crazycage

yeah ok...

Altratz

i ran 11.3 at the pod earlier this year but that was slower launch times and binding brakes then i got stopped for going over the 110mph terminal speed without a helmet lol.

FredElliot

Haven't the schools gone back yet?

In fact 0-60 in 6.4 in a fiesta with a "cone filter & big bore exhaust" gives me my first excuse to use this smiley

DangerousBryan

in my 2.9tt sierra 4x4 you had to be brutal. 5k rpm and side step the clutch at the same time as flooring it. this would result in 1.7 60ft's and the tailpipe hitting the floor. only had 260hp but would leave most scooby's/evo's in its wake as they were afraid to launch.
the cavalier was totally different. 300hp fwd. launch just above tickover on half throttle and short shift into second then floor it. best 60ft out of that was 2.3 seconds. but it was doing 110mph across the line.
the m3 i hold revs at 2k then just bring the clutch up normally and floor the throttle,results in little or no wheelspin and a 2.1 sec 60ft.

best 1/4 for the sierra was 13.5@100mph
cavalier was 13.9@110mph
m3 is 13.81@102mph

11.3! thats rapid, surely your 0-60 should be quicker?

Think he means 12.3, still a very quick car though, has all the right bits, running approx 400Bhp.

Launching a car is all about maximum power to the floor with no wheelspin or bogging.... Best way to do it, is find the point of peak torque of your car, then hold the revs 2-300 Rpm above it. Most T34 Cossies will be around 4.5k, T3's about 4k, T4's you need around 5.5k..

Hold the handbrake on, and nip the clutch until you feel it bite, and start to drag the car forward. Now, ease the clutch back in, but keep the handbrake on tight. This keeps the transmission wound up, very very important in 4x4 cars as just sidestepping the clutch will rip it to bits, and rear diffs on 2wds suffer as well.

So now you should be sat at peak torque+ a bit revs, with your handbrake held on, and the transmission wound up nicely, with the clutch just below biting point.. As you launch, you need to smoothly bring the clutch in, just before you release the handbrake, and as the car starts rolling progressivly feed the clutch in, balancing the revs against grip, but never letting the revs drop below peak torque. If the wheels spin, feather the clutch, not the throttle as if you release too much gas the car will bog, and again if the car bogs ease the clutch in to bring the revs back up, adding a bit of throttle as you go....

Sounds like a long process, but with a good launch you will be doing this for about two seconds , before you are hitting second gear already!

turnover

forget what speed you cross the line ie terminal as with a better 60ft your terminal wil be less and if your 60ft is say higher than normal your terminal speed will be more,sounds wrong but thats how it works,also every 10th you gain in the 60ft normally will double up over the line ,so sort them launches out lol

i dont think my 60ft's getting any quicker now, 1.7's with god knows how many attempts, maybe with my rebuilt turbo i can get it on boost slightly lower to have less wheelspin.

Rear beam and TCA's next then, set to zero degrees camber or even slightly positive to allow total tyre contact on launch!

WongRS

iTrader: (11)

hmmm, if i was taking it that seriously sounds a plan, but my next plan is take some interier and my install out and see if i can hit low 12's.

RWD_cossie_wil

iTrader: (9)

Interior out won't make a huge difference, rear beam will..

WongRS

iTrader: (11)

but interior out costs nothing, rear beams is like £1k+. lol.
as i said, im not hugely fussed, im not competing in drag racing, all i ever wanted was it to run 12's, and it does, thanks the advice though.
One day i will put a beam on it!

launch control on fiesta lol

Tank Mike

Been trying a couple of different thing recently based on the advice on this post.

Fantastic advice aswell so thanks to all who have replyed.

Ive got 2 so far that i have been really really happy with.

It makes such a huge diffence and a very small fuck up costs big time.
