hmm, the car should have much more in it then that, even in the 83f heat. was the car sitting in the staging lanes running for 2 hrs between passes? or did you get a chance to turn it off and let it cool down with the hood open? i agree, t/c off should do ya better, i always put the autostick into 1st ont he line and just let it shift itself from there out. i assume a/c was off, windows up, took out extra luggage/subwoofer enclosure from trunk, ect.. right?

 

I'm gonna put about 200 miles on the car between sat. and thurs. nites test session, air should be great about 55 degrees, gonna turn off the traction control and let er rip! Yes car was empty, less than 1/2 tank fuel, cooled off between runs with hood open.

 

Hold the brake and rev the engine up to about 1800rpms then just left off the break and quickly roll into the throttle when the lights go green. You will have to feather the throttle as it will definitely spin (or at least mine does).

Remember that you aren't too worried about reaction time (unless you have a grudge against the guy next to you). At a place where you get so few runs, just make sure to pay attention and get a good launch vs. trying to beat the competitor off the tree.

Let us know how it does! It should be a mid to low 12sec car, especially with those 60's!

 

I've tried to launch a few time's with the TC off, but RENNtech kit + Sprint Booster = a lot of spinning(not at a track). The few times that I have tried it I was using my G-tech meter and it showed like an 11.7 in the 1/4, as much as I was spinning I just wrote it off as a bad reading.

 

My car was faster if/when spinning at the track then it was when I had the help of the T/C.

If I "tap" it over to 1st at a stop ..., it will pick up and run through the gears as I accellerate? I was afraid it would just redline 1st and hold ...

 

It will shift for you. Just put it in 1st, mash the gas and hold on! Actually, if you put it in first and are hard on the gas - and TRY to shift to 2nd, it wont do it. It will hold 1st until the car is near redline and at the car's optimal point to hit 2nd gear (same with 3rd and 4th).

It's a smart auto, no doubt!

Wow, I didn't know that either. I was always scared to test it out thinking it would hold the gear and break something. I kind of suspected since it really wouldnt shift until redline on hard launches even tho I tapped the stick to upshift. Good to know for when I go to the track.

 

I was told it could take up to 300 miles for My Ecu tune to fully adjust, and over 100 miles for my new plugs to fully sink with my Ecu. Give your car a little more time to adjust, and watch the times come down....

 

**BUMP**

How did your Thursday nite test session go?...

 

Rather than starting a new post on the same ole' ****, im just gonna add to this one.
I ran 16 passes last night at Ennis, TX(1/4 mile).....not a single 12 Best was a 13.082 @ 107 with a 1.999 60ft.

I was so sure id run a 12.999. The weather was fair 65-75 or so. Id say a little humid. I just couldnt get my 60 fts down below a 1.999. Now it didnt help that i ran back to back passes with only brief 15-20 min cool downs, but i was concentrating more on getting low 60fts, which never really happened.

A couple questions for you guys that have drag raced your srt6 on street tires.

1. Do you burnout.
2. Traction control on or off.
3. What rpm do you launch at.
4. Do you start out in drive or in 1st gear.

I have to get my 60 fts down.

 

That's not bad at all - sounds like with some better traction at launch you'll get into the high 12's. Once you get your pulley/tune installed - then......

I think everyone who as tracked agrees that you should turn the TC off.

 

Oh yes, a pulley is comming sir.

Last nights method was as follows:
Drive in straight off the highway, tech in, line up. Pop hood to let plenum/intake piping cool down. Fuel tank at 1/2. Check tires to be 35psi. Burnout in prestaging lanes and get yelled at. Apologize for being rusty and say its my first time to avoid embarresment. Drive around water pit and do a dry burnout. Put in first gear. Rev the throttle to 1500rpm and hold down brake. Go on 3rd yellow! Let off brake and briskly and push down throttle simultaneously. 2.0 60ft , 13.392 @ 104. At least it wasnt a 14

Througout the next 3 hours and 16 back to back passes, i adjusted my tire pressures from 35 down to 26. All night long i was able to launch 2.08-2.09 60fts regardless of the tire pressure difference, so long as i launched between 1000-2000 rpm's. Launching from idle was worth a 2.1 60ft. Launching over 2000 was worth a 2.07 60ft. I was afraid to launch over 2000 rpm because at 2000 rpm the tires are really trying to break loose to the point you can hear them creaking about to spin, and i didnt really know how hard that would be on the stock tq converter(ive never drag raced an auto before).

My test for next time will include launching OVER 2000rpm to see if its beneficial or detrimental on street tires. Also, i will play with air pressures more. Im going to do a few 35-36 psi passes....then take it all the way down to the low 20's to see what happens. Id also like to try and figure out if theres any difference in 60ft's if you have the car in 1st gear vs. drive.

And then when i get all that down....let the car cool down for 1 hour....and hopefully hit mid to high 12's.

 

1. NO burnouts are ever necessary on street tires
2. Always have traction control OFF
3. I launched at 1400rpms, rolled into throttle and still spun the tires a little(2.0 60')
4. Always start in 1st gear(manual mode; let car do all shifting)



Your 60's aren't bad at all for street tires. The big problem which is killing your times is heat soak. The car will run .3-.5 seconds faster if you pop the hood and let it cool off for 30-45 minutes between passes. I bring a bag of ice and a small towel and lay it on the S/C after every pass and will not run again until the the temp gauge is is around 1/3 mark. I do the same thing with my Charger as well and consistantly run .4-.5 seconds faster than running at full operating temperature.

Also as far as air pressure goes you should air up the fronts to about 45psi and air down the rears to around 30psi(no less than 27psi) on street tires.

 

I heard ENNIS was supposed to be a pretty fast track too. But down south here, the heat + humidity is a killer. I hope the weather will be cool when I go to the track in two weeks for Import Face Off, or else I might end up with similiar results as you. I'm about to try some ice(maybe dry Ice too) in my ghetto made intercooler resivour tonight, so hopefully that will help.

 

Looking at your mods, your car is bone stock! That is a good time! I don't see anything in your mod list that would speed you up. By the way I left in Drive with traction control on(when I was nearly stock). When stock plus needswings cai, Cracked a 12.79 check dragtimes.com. Good Luck

 

Thanks for the tips. Now that i have the launches down better than before i will allow the car to cool between runs and use a bag of ice to extract its full potential. Ill also air up the fronts as suggested. And a few more mods in store shouldnt hurt either.
