[Mk2] [Turbo] Best launch method...?

Post by shabz »

Whats the best way to launch a 2 off the line...running say 280-290fwhp?

Is there a clutch friendly way to launch fast? and whats the fastest way to launch regardless of clutch?

Since the boosts been turned up all that seems to happen is lots of wheel spin

(I know this has probably been covered before but I've been searching for 15mins and couldnt find anything)

Lower your rear tyre pressures to somewhere around 10/12 psi. Let the revs rise to something like 4500rpm (it'll take a few lanches to find where the car is launching hard without much wheelspin), then sidestep the clutch....

...yes, I did say sidestep it. Let it spring back up. If the revs are right, you'll get a hard launch, without much wheelspin, and be heading for the finish line. :wink:

Yup, side step means 'Let it go!' and once any possible wheelspin has gone, Get the throttle 100% open!

dont double clutch it tho!

Earl, how bad on the engine mounts is hard drag launches? i managed to kill a mount on my old escort from dropping the clutch too hard and eventually that led to me popping out a driveshaft :shock: had to push the car 1 mile home at 2am ! lol

Again does sidestep mean flick your foot sharply to the left onto the sort of resting panel letting the clutch spring up pronto???

he means completely let the clutch ping up by flicking your foot right off to the side id imagine.
ie, you literally have only your big toe on the depressed clutch, and flick it away and the clutch will ping up.

dont no how comfortable i would be doing that, lol, but seems to do the trick.

Yes, by sidestep, I mean slide your fott off the cluch, and let it spring up.

Unfortunatly, it's quite hard on them. The Beast had poly inserts to combat the shock, but it's something you have to live with mate. Drag racing is hard on virtually all components. :eye:

ok i see.. Hmm well considering that then, looking at that 'under engine brace' that jeff uses on hyde, would that not cause more problems than its worth? i notice that hyde's one had bent up a few chassis parts...

Earls advice of dumping the clutch (ie foot off to the side, clutch from engaged to not engaged in fraction of a second) is kindest on the clutch. some people find they get a better and faster launch by slipping the clutch off the line. (this method is crueller to the clutch though).

double clutching makes for a slow gearchange, as you are engaging and releasing the clutch twice instead of just once. it's also pretty much unnecessary in any car made after the model T ford.

I thought 'doubling the clutch' was a method - wagon drivers use to go up and down the gears - for a smooth gear change...

double clutching has 2 versions.

1st version.. a method of shifting gear in lorries with old boxes (i think before syncro's were invented). basically to sync the gears up ready to shift you would have to - Press clutch - Remove from current gear - Release clutch - Reapply clutch - Select next gear - release clutch. I am not 100% sure on if this is the actual method / purpose but i know its somewhere along thoes lines.

2nd version is a boy racer term. Basically when you are in your Saxo / Nova / Clio / Corsa and are at the lights racing another chav-mobile of a similar spec, Say in 1st or 2nd gear, and you find your opponent is pulling infront of you, You may decide to; while maintaining WOT, quickly press and release the clutch in a split second, to basically 'Rev' up the engine and give you a slight 'split second' burst of power and possibly gaining you the win, but at the expense of damaging your clutch / mounts / gearbox. but who cares there chav-mobiles!

Dumping the clutch is tough on the drive shafts though :evil:

I personally slip it off the line, and will be doing on the new engine to try save the driveshafts.

Toe and heel is another good thing when braking and changing gear.

Yes Ryan your 1st version is 100% correctamundo......

If you are changing down i think it is stupidly uneccessary!!! :roll:

Clutch in
Put into neutral
Clutch out
Blip throttle and clutch in
Change down gear
Clutch out

:shock: What a ball ache lol!! I just prefer to blip the throttle when you depress the clutch to match the revs when you come down a gear......Whether this is correct i don't know but works for me!!

Jim, PMSL mate!!!! :lol:

"Heel and Toe" :oldtongue: :wink: is really only necessary for track driving........I can only do it in bare feet due to having size 12 and the pedals being where they are :lol: Tried it in my mums golf with immense brakes and almost emergency stopped :lol:

Heel and toe can be scary to get the hang of because if you try and blip the throttle too much, sometimes you end up braking harder in a sharp burst as your whole foot has depressed rather than just your heel :roll: :lol:

If you try and heel-toe and braking softly it doesn't really work as you need firm depression on your toes to control the depression of your heel better :thumleft:

Yeah thats right you cant really use it in street driving but there are times it can be done. if you practice its a good thing as important as a good launch in my opinion.
