First 1/8 mile times. Not happy

What air pressure. I run 18psi . I try to lunch at 3000 rpm. Was the truck cool or hot? Mine likes to be cool.
Hurt my neck reading your slips..

I was afraid the tires were gonna break loose at the line if I took it above 2500. It just sucks to think that I may have a low 14 second truck.TNVIPER said:Hurt my neck reading your slips..
This your 1st trip to the track being timed?....if so just be patient you will get better......and tracks vary too....you might run easy 13s on another track...

No sweat Steve, you should still be ahead of Viperqueen!!!
And Roy.
If it was a stick shift, I wouldn't be so worried. But, Being an automatic, I can't do much but play with launching rpm. And, like I said, I don't think it will go much more than 3000 rpm. The truck feels like it's running fine. A/F ratio is around 12.0 - 12.3 through the entire run. I don't think there's much more that I can do performance wise without going F.I. Like I said, any advice is appreciated. Thanks guys.TNVIPER said:

Now I see the reason for the text. No worries bud, it could be the track?? That means I'm I. The same boat.....NOS time
your 60's are awfull expecially with a tire,, Ive seen guys with a stock tire and a qc run 1.9s no problem... If you have a tire you are doing someting seriously wrong... or your truck has serious power problems..

It could be the DA which makes a HUGE difference, especially if your at higher elevation. I had a day like that back when my truck was stock.
Our track is only 38 feet above sea level, but with the temps being so hot and humid combined with low barometric pressure, the DA was almost 1800 feet. 2 passes and couldn't break out of the 14's that day, ended up with a best of 14.008@99 which for that DA would calc back to a 13.7@101. The DA makes a real big difference and can make or break the times your aiming for.
You should be cutting a 1.8 easy with those drag radials, running somewhere in the mid 8's, and trapping over 80mph.
-Check what the DA was
-How much miles on the truck? Could be it's time for you to change tranny oil and filter and rear end oil, maybe even adjust bands and check sol.
Do you notice the tranny shifting softer, or a hesitant 2-3 shift?
Goto this page and type in the info for your track, find the time of day you ran, with that you can get your DA for the time on thier page and calc back to give you an idea on how the DA affected your runs.

I ran consistent 8.3's with similar mods on street tires. Your 60' would indicate you are being a little too easy off the line. With DR's, get them hot and slam the gas pedal to the floor. A 1.9xx 60' will get you a much better time.

I'm jealous, 8.3 1/8th mile is in the 12's for the 1/4 which I'm hoping to break into next trip. All this time and still only made one pass so far that my back end was sliding out to the side on me forcing me to let off.
Thanks for the response. Truck has 21000 miles all the fluids have been changed in the last 1000 miles. It was at the trans shop about 1000 miles ago, to rinstall the upgraded gm solenoid and they said the band adjustment was good. The tranny seemed to be shifting good.ViperPowa said:
I checked the link and it said the DA last night was 1980 feet. Corrected is a 13.799 ET. Which makes me feel a little better. But i would like to have ssen the times on my slip
