went to the track today and was very disapointed.
here are my runs
first run----------------second run--------------------third run
2.34 --------------------- 2.29--------------------------- 2.33
9.79 ---------------------9.57----------------------------9.59
14.97@95.3----------14.77@96.4------------------14.76@97.0
i dont undersatnd why i ran so slo, my last year best was a 14.35@99 with a 2.29 as a 60 foot time
i got the same 60 foot time tonight but not even close to the same mph or time.
i checked my actuator and its fine, what else could cause such a difference in track times by the way the track conditions were very similar to last year.
i recently had major header leaks 4 to be exact and had that fixed. a month ago i ran with the leaks and ran a 14.5 so now that the leaks are fixed i ran even slower, im puzzeled
by the way i have a comptech icebox and obx headers

You're only off by a few tenths...
What are some more variables that you're leaving out.
Weather, was it the same?
Tires- New, Older, Same pressure?
And for Shits and Giggles, what was your reaction time. I know it doesnt help but it eases my curiousity anyway...

Temp : 53 deg
Humidity: 50%
wind: 13 km/h O
pressure : 101.9 kPa
reaction time were somewhere around .3 but that dosent make any diff

and Yes 4/10's is a big difference but not when you didnt originally mention those extra variables. I mean you can lose a 1/10th for having a full tank of gas and you laptop bag, what do I know.

I've recently had some slower times as well. One day I ran 13.9@101 where my car previously ran 13.4@105. I was pissed. The very next week I ran 13.6@106 without changing a thing. Humidity plays a big role as does track-prep/temp. Just go back again in a little while and I'm sure you'll be happy again.

i also found it weird that i had to change the plugs so soon

I have a feeling that running with barely any gas actually hurts your times, regardless of the fact that the car has less weight.
I went to the track last weekend and ran 14.8 @ 96 (stock) with my fuel light on. I'm gonna go back with a full tank and see what happens. The real killer is the stock tires for me though, yielding 2.4-2.5 60' times.

Well, my time of 13.9@101 was .5 seconds and 4mph slower than my best of 13.4@105. No mods have been done in between those track days. Conditions are a major factor...especially if you're NA. People on the boards have always spoke about how awesome their cars run when cool/dry conditions arrive in the fall.

i went back to the track today and got much better times.
60 ft 2.314----------------------------- 2.310
1/8 9.428----------------------------- 9.46
E.T. 14.51 @98.6--------------------14.56 @98.4
temp was at 52 deg
if i can lower my 60 footer my times would be much better
what pressure do you guys leave your tires at?
mine were at 28 psi and was still spinning all through first gear

go down to ~20 psi
#22
Nah, I wouldn't lower more than 25psi. I found it's best with 2.1 (60') on my street tires (BFG KDW 2) but my car has power
Track condition/humidity plays a major role too
