I have a stock xr6t ute with 5500 km on the clock that i really want to run down the quarter to see how she goes.Ive got the chance to do it next weekend but only for a couple of hours due to work commitments,so i want to get good time in only a few runs. Can anyone offer any advice on the best way to race it? Should i stall it up(mines an auto)? What revs should i change gears? What sort of time should i expect?

Here is what i do.
Warm up tyres a little with small burnout.
Have car in performance mode and let it change itself
Foot on brake and hold revs to 2000rpm
On green let go of brake and put accelerator to the floor.

This should result in no wheel spin and a good launch.
You should do the 1/4 in roughly 14.00. Between 13.8 - 14.6. Depending on track car and temps.

Geea.

Thanks mate, hopefully i still get the chance to give it a go this weekend. Ill let you know how i go

i wouldn't bother doing a burnout on standard road compound tyres

they are designed to work at normal tempretures, not high tempretures like semi-slick and slick soft compound tyres

i loose traction on my tyres after a small burnout.
on the road.

perhaps the track is diff.

And launch on the 2nd orange light. By the time your brain sends the signal to your foot and the car reacts to you saying go the light will of gone green. Will help your reaction time out a great deal. If you launch on green you will lose a bit of time

Mmmm, lots of incorrect info here.

You do need to do a small burnout, firstly to get the water off the tyres, secondly, even street radials benefit from some heat. Just not as much as slicks do, but you certainly don't want to launch on a cold tyre.

Also don't worry too much about the reaction time, as it has no bearing on your ET.

I would also lower your rear tyres down to approx 20psi, and put 40psi in the front.

Why would there be water on the tyres?

Tell the guy not to spray water on the track, or drive around it, i had a 13 second soarer that ran slower (had less traction, lower ET, v.similar MPH) after doing small burnouts on 255 sumitumo's...

So long as the tyre has not been just sitting in the carpark for 2 horus it should be warm enough to develop decent grip...

try both, try doing a small burnout and try not doing a burnout, it may completely depend upon the compound used in the tyre

Because there is always water in the burnout area, it's supposed to be there, to make for starting a quick and easy burnout.
No can do, you have to drive through it, and for good reason, to do a small burnout.That's very rare, and doubtful.
But that's just it, all cars do sit for a couple of hours between track arrival and there first pass, and then at least another 30-40mins between all other passes.
In any case, it will only take 10-20mins for a tyre to cool below it's operating temp.
I know where my money is.

YOOT

The idea of a burnout isn't so much for heat (slicks it is) its to clean the shit off the tyres, thats why your supposed to power out of it not sit static.
