MPH 90.42 90.29 92.03

also the car has been running a little ruff so i have to figure out what is wrong

and i would have thought being an auto it would have been more consistant

there was quite a bit of hummidity so that played an effect

 

hmm.. well you definetly neeed to get that 60" down...

i pulled a 2.333 60" and still achieved a 14.6 @ 98 (shifting slow into 2nd)

is it your first time at the track? get the 60" down.. get a tuner. it will make a world of a difference with an automatic

 

no it was my second time


i know i need to get the 60 down but how is what i want to now i was not spinning any

i know i need a tuner so i am taking it to brenspeed and haveing them dyno tune it once i get money

 

Even though you have an auto you DO still need to know how to drive it. With the auto its mostly in the launch. Keep practicing and i bet you can shave another .5-.8 off with only practice.

My auto bone stock ran 14.0-14.2 consistently after i learned it. My frist time i was only doing 14.7 or so.

 

ok what did i do wrong i let my track control on the first time and that may have hurt me but i did not spin at all i had my rpms to the max of the stock stall

 

Elevation here does play a role. What is the elevation at the track?

 

i dont remember what it said but around 800 feet i think

 

If you are not shifting the gears manually, you might try that. I made a couple runs letting my car shift on its own, and my time was a full second slower than when I shifted it manually. I run both 1st and 2nd gear up to just shy of redline.

 

i thought about that but mine doesnt like to shift when i do it manually it had trubles when the car was new

 

You say you didn't spin, did you bog at all of the line. I know on all my 2.360ft'ers it was because I was bogging of the line. Still learning the car. Even with 2.3 60's I was at a 14.5 (speed shifting from hell). Also you said it's running rough. Check that out. Could definately be hurting you. Looks like you might be loosing a little top end too.
