dragging with auto?

I know someone who took his 2000 gt to the track to get a baseline time and started off the line in first gear and then maxxed out the rpm's before shifting up with his auto trans. Is that the proper way of racing with an auto? Just wondering cuz I want to get a baseline time for my car with aod and stall torque converter.

you NEVER EVER want to put it in neutral and then put it in drive to take off *VERY BAD*

the best you can do is to hold the brake and rev up until right before the tires spin. When the light turns let off the brake and get on the gas.

I don't think he started in neutral. He started in first and manually went up to 2nd and then manually to drive.

oh, I see. On newer transmissions its not an advantage to manually shift, let the computer do it for you. A tune can modify shift points and pressure much better and can get better results than you trying to do it yourself.

You can try that to see how it works, but you may be better off letting it shift for itself.

They used to do something called the 1-2 shuffle in the Fox Body auto trans Mustangs. Don't remember exactly why.
You might want to research that and see what you can learn about it.

SpectorV, he has an AOD not the AODE unless he has changed it, so tuning the shift points with a tuner won't work.

Your choices for launching are foot brake or use a line lock.
You will have to experiment a bit to determine your optimum launch RPM.
You want it high enough that it doesn't bog and low enough that it doesn't spin.

Yeah I have the stock aod. As far as the 2000, he already tuned it with the sct tuner which should have modified the shift points already?

Is it a waste of time to heat up street tires?

No, but then you won't ever see the benefits from them as easily as you will a set of slicks or drag radials either.

The sct tuner for the 5.0 should be a chip. Can't just scan them like the 4.6.

The 1-2 shuffle..
Is when you manually shift into 2nd then pull back into 1st. When you do this the car does NOT shift back into 1st, but allows you to keep it in 2nd and manually shift into 3rd. This is not a great way to treat your tranny, but it will allow to control the 1st - 2nd, then control the 2nd - 3rd shift.. Use this at your own risk.

Yupp...can be detrimental to your trans...but I've done it a dozen or so times with no consequences.

My understanding is that it is a fail safe to keep the driver from tearing something up V. Performance option lol

That's it. I couldn't remember the particulars.

Thanks!

Np man! I had an 86 5.0 T bird and an 91 3.8 T bird, I shifted both those cars this way. The 86 was total lost before I got torn up, but I did tear up the one in the 6 that way... SMH
