launching on street tire

I hate Rice · 09-08-2001, 03:04 PM

What is the best way to launch an automatic on street tires? Should I power brake or should i just gun it. Also is it faster to shift 1-2-D or just put it in D and go? I am racing a Eclipse GSX AWD with light mods and I need all the launching help I can get. Thankyou.

I would heat the tires up real good. Then hold your brake while giving it gas until the tires are about to spin then wait for the launch signal. Run through your gears dont let the trans do it. It will shift before its power peak.

don't mess with "heating up your tires", on a street tire it does nothing, and on the street, it does even less. if you do go to the drag strip, you should do a quick burnout (1 sec) just to clean off the tires.

you like dancin? you better, cause its time for...The AOD Shuffle!

ok, start by putting your car into 1 (alllll the way down, press the button and put it back). put your left foot on the brake, and use your right foot to bring the revs to ~1000. when you are ready to go (don't sit like that too long, it will burn up your converter) release the brake and slowly depress the throttle. when the revs hit 4800, push the "gear selector lever" up one notch (to the "D" position). the tranny takes about 300 rpm to shift, and once it has fully shifted, and youve waited a second, press the button and pull it BACK to the "1" position. when the revs hit 4800 again, put it in "D" and leave it there. finally, when they hit 4800 put it into "OD", but by that time you will really be movin....i do the entire 1/4 in 2 gears, going just out of the powerband on my 90LX convert.

a stock mustang stops making power at about 5100ish,so given it takes 300 rpm for the anchor to shift, you move the shifter at 4800. your AOD has 4 gears, the "1" position only lets the tranny use first gear, the "D" position lets it use the first 3 (1,2,3 DUH!) and the "OD" position lets it use all 4. the problem is that if you let the transmission shift itself, it does so a few hundred rpm too early, this is worth a couple tenths in the 1/4. the other problem is that you only have a distinct position for 1st gear (the "1" position), and the first 3 (the "D" position). in order to keep it in 2nd gear till the perscribed rpm, you have to bring the shifter back to the "1" position, after letting it shift (by moving it from "1" to "D" and then back to "1"). Cause you have to do so much fancy work, its the aod shuffle. now, be careful when you are shifting into 2nd gear that you put it in the "D" position and leave it there long enough that it is completely done, before you bring it back to "1" otherwise it will downshift to 1st and that would be bad. if you ever feel quesy about doing this, just push the shifter forward as far as you can (WITHOUT pushing the button) and it will stop at "OD".

You mean I am wasting good tires when I do burnouts? Well you learn something new everyday.

I agree with Dinomite. Heating a STEEL belted radial just makes it expand (gives a result like overinflating the tire). Then when you launch the tire just spins(no flex). Just do a little tire cleaner, avoid the water box, don't deep stage, and dance like a monkey! Good luck

I don't have a AOD, but I love when Dinomite does that dance thing

! I totally agree.....long burnouts on streets will do nothing helpful - it'll actually hurt you. Another thing, that noone mentioned, I would let some air out of your rear tires (till it just barely "bubbles out" on the road.......VERY helpful! Good luck - let us know how your dancin' goes! P.S. Practice some launches before then!
