Ok i am going to start working on my car after i go to court and all and i was woundering what ppl have dont to there cars and what your 1/4 time is? and is anyone running NOS? Thanks for all the help guys

 

nice white ss

 

I have a 2.4 auto and my best 1/4 is I think a 16.32 at 83mph, but I still haven't learned how to launch it right. Only mod is GMPP touring exhaust.

 

Thank for the complament and my best all stock was a 15.879 @ 85.29 mph

 

my stuff listed in sig

 

mods and best run in sig I was thinking about nitrous if I did full bolt ons, but I'm gonna go the supercharged way

 

its either dat or a horrible reaction time 16.32? stock is 15.8-15.9

 

or he lives on mt everest, whats the elevation where you live??

 

mods in sig.

 

Dude, reaction times have no impact on Elapsed Times

 

How do you like the sound of the dp w/o the cat?

Thats the truth cause i ran faster with worse R/T

 

It's very unique and loud. The flowmaster makes it real deep. Love setting off car alarms in the parking lot.

 

My mods are listed in sig and I have not run the 1/4 mile yet.

 

with my mods what would u expect on my 1/4 time...15.3-15.5 1/4?

 

my elevation is approx. 60ft above sea level, I think I just got a slow one

 

what octane gas are you using?? what about tire pressure?? what about check under the hood to see if its really the 2.4 lol just kidding. i dunno. it could be the track too. have you only run at the same strip??

 

i'm running 93 octane Shell V Power gas, tire pressure ranging from 28-35 lbs, and run the same time at two different tracks. Maybe that nitrogen in the tires is making me too heavy I'll be getting a dyno tune soon, and I'm hoping GM just REALLY fudged the tune on it from the factory. Lol, can I bring it back and say "Hey, my car's slower than it's supposed to be, I demand a faster one!"?

 

Are you launching in "L" and then shifting to "I"? I understand that if you leave it in "D" you get earlier, slower shifts. Others have said that the cheapest improvement in 1/4 mile time with the auto is either HPTuning the shift points or using the shift reprogramming box (I had one but never got around to installing it before trading off the Cobalt). Also, are you torque-stall launching it? You do need to have a good understanding of the process so you don't hurt something, but holding the brake and taking the "slack" our of the torque converter prior to the green is also worth a few tenths.
