Question

Will be picking up my Scooby this weekend, as I have never owned a 4wd car my question is:

Your at the lights & you want to get away quick wots the best technique?

In my previous car (Corrado VR6) i had to set off slow and then put the power down otherwise i would spin mine front wheels for fun due to the tourqe.

I've heard that the best way is to put handbrake up, hold throttle at around 3500 rpm bring clutch up to biting point, soon as lights change release handbrake, drop clutch and throttle down?

How long do you want your clutch and drivetrain to last?

well i've been told, and yes i have tested it, that the best way is to leave the accelerator alone until you've brought the clutch up and the car is rolling then floor the right foot! it's something to do with it being a turbo'd motor. otherwise you will burn the clutch on too many occasions, just like i found. i'm still trying to get rid of the smell...or is that me?

You'll need more revs to beat the turbo lag - about 5k should do it for a quick start. Feed the clutch in (it will feel like its being ripped away from you when it bites) and keep throttle nailed. You have to be very precise with the upchange to prevent the engine bogging down. The wheels won't spin (I haven't spun mine yet, though I did in my old 4x4 Cossie). Bear in mind that full-bore standing starts will cause considerable strain on your clutch !

Drive to Manchester, stop at the lights, get out, and wait 2 minutes. You'll then see it fly off in the biggest cloud of smoke this side of an Iraqi oil field.

Waiting for it to roll and then put foot down will result in waiting for the turbo to kick in?......will try out though!

I've seen some scoobys espicailly at 1/4 mile track days leave the line at some speed!...they seem to squat down from the back and then just take off!....i think that is the handbrake job......and yeah probably will need a new clutch!

Rev to 5500 and drop the clutch whilst simultaneously flooring the throttle. Change up to second 0.1 second later.

Cool

But dont think a clutch will last you long

after a standing quarter up the local airstrip the other day, i found that 5.5k revs, clutch on biting point (couple of secs before launch), followed by dropping of clutch and quick upchange, provided me with best results. smelt a bit, but hey that is the trade off!

Its a lot cheaper on gearboxes and clutches to just start normally and once you have it rolling then wind it up. You will soon pass the other car in most cases and you can give a "friendly" wave as you pass them and change up another couple of times. Much more satisfying too

Just like Bruce or Peccy say, assuming you do not mind abusing your vehicle. The actual revs depend on the car and road surface, weather etc but somewhere between 4 and 6k will be the G-Spot.
This technique was good for 12.28 1/4 in the rain recently.

Had my 03 WRX for about two months. I find getinng the car rolling before glooring it definitely results in slow acceleration until 3000 revs, as said above though you'll usually catch them up quickly enough tho.
If i want to fly off have the engine at about 2500 revs and eas the clutch off, so that the 3000+ rpm boost power is applied after the drive is fully engaged.
Will this be easier on my clutch or am I kidding myself, and will subaru replace a clutch under warranty?
