Best way to launch a manual?

[miller]

Ive had the auto up to 4500k at launch. Beyonf that even the handbrake and footbrake cant hold it.....but boy does it go like a scalded cat! VERY hard to match it with a manual. When you can spin all 4 wheels in the auto in the dry then you know you have a good launch...

lol, cheers lads, i think ill wait for better weather and better brakes before attempting this!

Lalala I can't hear you Kidding mate!

I'm trying to keep it under control, I've only done it once, fluffed it, thought I better ask before I try again

On a 1000% serious note , you need to bed the clutch in for at least 500 miles before even trying anything like an agressive start or you will paying for a new clutch to be installed again

Admittedly both Nick and Richy said that, I've only tried it once and I'm not going to be doing it again for a while, I'm roughly about halfway to that 500 miles now so won't be long I guess.

best way to launch a manual is to convert it to auto!

[Gowf]

on a manual 5000+ rpm or and you will move like sh!t of a shovel , any less than that and you can bog down as I found a few times

6000+ will induce wheelspin but when the tyres have finished getting hot they grip like nothing you have felt before

but in simple terms , dont do unless your willing to buy a new clucth as launching really should be left to twin plates or tripple plate clucths

5000rpm? You'l spin all 4, easily!

It all depends on how you do it. Yes you do want to be on boost, but you wont achieve that unless you have some form of launch control (unless in an auto as you can load it up). When launching mine, i stuggled to get any traction at all, and that was on Pzero's. The only way to do it was keep it relatively sedate, around 3kish and build the boost up by blipping the throttle, then when your ready to go, go on that blip, with a bit of clutch slip if it will allow.

Also bear in mind that I went through a exeedy paddle clutch very quickly indeed with that. once wheels were spinning as they always did, you couldnt get 2nd straight away, you had to wait for the clutch to chill a bit. (about a second).

Now im on the tripple plate i dont have that problem at all, its just everything else that breaks, but again, traction is a major issue. I've never launched on the strip with launch control on, as never got chance to set it up properly even though it does make a bar sitting on the line, but what i will say is this.......... when your going and your right foot is firmly planted. KEEP IT THERE!!! dont lift when changing gear. It means you've got to be quick and not mess it up, but flat shifting is the only way. that way you dont go off boost.

But ultimately, what a lot of the evo's do, and i was always tempted to do it but never got round to it, get the revs right up and use 2nd gear, then you'l launch properly! BTW, my best 60' was 1.9, which is pretty apauling to be honest. Not as bad as the worst that was 2.8, but andy (aboo) can tell you more about that one!

At the pod 5000 rpm was just about right to get off the line without much spin , beyond that and all four would light up

launch control set at 4000 rpm just bogged down on launch

quickest 60ft i can remember was 1.86 on a nice warm day which gave me a 14.1 as I had no 4th gear so passed the line still in 3rd

Drag launching is a bit of an art, but my advice is, if you are not prepared to break stuff, DONT DO IT!

Launch RPM depends on traction conditions, if there is more grip, you can use more rpm, if there is less, then less. You have to feel it a bit. What you want to do is chrip the tyres and grip, but not bog the engine out of the spool range.

So what i tend to do if i do a no l/c launch is blip the throttle causing the revs to rise, then release it, cuasing them to fall. I repeat the process, holding the clutch just on the bite point and resisting motion with the handbrake (This preloads the drivetrain to help minimise damage from shock loading). i go vroom, vroom, vroo..... and just as the revs rise through my chosen rpm (with the turbos spinning up) i dump the clutch, floor the gas, and release the handbrake. Off you go! Hopefully.

Drag launch is very hard on the drivetrain components. Shock loads will smash stuff to bits, and holding the clutch dragging smokes it pretty quickly.

Cheers,

Ben.

Thats because you wernt making boost from the launch control. The MAP's LC isnt really very good, or at least it wasnt originaly. It made all the good noises, then they changed it and it sounded very lame. However, proper lc with antilag does what its meant to do!
Santa Pod is usualy pretty bad for fwd on the rwyb days as youve got to drive through the bloody water trap and then go on a not very sticky strip as they dont want the clio and corsas out there to be snapping shafts every 2 seconds.

Yes I can that's cause it was the wettest day in Scottish history & you never got traction till you went into 4th

I'd add my 2 cents of launch method but I say just go to the strip and have fun trying different methods! Everyone will have different opinions but in the end finding what works best for you is half the fun

[VR4WGN]

screw the lunches lol.. just get rolling and let your opponent think theyr winning then STAB the Clutch and accelerate and be amazed at the picture of the car next to you in your mirrors....
i find this technique most helpfull in aiding the drifting too but i do not condone it lol,, i use to do it on my workshop road,(rural ish)

[twisted32]

If you want to launch, but want to minimise driveline breakages, the method advised to me by an Evo specialist was to sidestep the clutch, but ensure your rev's are high enough to get wheel spin. If you don't get the wheel spin, you driveline will load up, and then increase the risk of going bang (he actually had a nice example of a gearbox casing that let go around the input shaft from a customer not giving it enough to "unwind" with a little wheelspin).

[nuster100]

I use the tried and tested method of foot on the brake, then 3500rpm with the other foot.

My friend has a lancer GSR turbo and he sidestepped the clutch at 6000rpm, the back of the car squatted so hard it hit the ground!!!!!
