Well, here are the times and the problems.

Track times

Run 1* Run 3** Run 4** Run 5**

RT +.727 +.423 +.615 +.492
60ft 2.137 2.180 2.233 2.216
1/8ET @ mph 9.063/77.12 9.109/77.63 9.268/76.43 9.244/77.24
1/4ET @ mph 14.142/96.18 14.147/97.06 14.399/95.27 14.320/96.20

--- Runs 1 and 4, engine hesitates

--- Runs 2 and 6 were total screw ups on my part.

--- Runs 3 and 5, launched at about 15-1700 rpm, no stalling/engine hesitation (okay, going in the right direction).

*Timing @ ~20 degrees
**Timing set to ~14 degrees

My evaluation as to what's keeping me from getting into the 13s and how to fix it.

3) NOT ENOUGH TRACTION. A friend of mine with a '91 GT had some Mickey Thompsons and he was hooking WAY better than I was. The thing is, I feel that I should still be in the high 13s with the tires I have now.(?) Also, I want to keep my car the same way as I drive it on the road (ie, no front sway bar removed, no slicks, etc.)
2) ENGINE STALLS/HESITATIONS. I found a way to correct this by launching @ ~1500rpm. But, it shouldn't hesitate in the first place (yeah, maybe the carb's too big).
1) DRIVER ERROR. I definately gotta practice. By the 3rd run, I decided to manually shift the C4 @ 5600- 5800 rpm and it helped a bunch. I just kept screwin up on my launches.

If anything, at least I can say that I achieved the fastest quarter mile times that I have ever run with this car:
14.142 and 14.147 beat the earlier champion run of 14.161 1/4 mile ET (w/ the 3.27 gears), but that's not nearly good enough.

So, going back to the strip this coming Sunday. I'll see what I can do.

Please excuse the length of this post, but being the Chemistry major that I am, I gotta analyze everything.
If anyone has anymore input/advice, enlighten me please.
