you should be 2.0-2.04 for 60 ft.
reaction time has nothing to do with ET.
1/8 mile should be 8.8-8.9
the 1/8 mile per hour is low... very low. 80-81 mph at least 79.
1/4 mph is ok.
it looks like your first 1/8 mile killed you. you need to drop.2 off 60 ft.
practice
practice
practice.
now you see how hard it is to get a good ET. you need to experiment with rpm's at the line. some cars like some tirespin then a solid grab for good 60ft. some like clutch slip to reduce torque on tire. MY best advice is to bypass all these techniques and purchase nitto DR's or whatever brand you like. the rear end will suffer.(spider gears). MPH trap speed at 1/4 was probably good because there is less shifting and more legs in 4 valve. 13.9 is a good time. What is your altitude? you need a correction factor.
but i must say, first ever time at a real track thay is an excellent result. there is no telling how much time you will take off with practice.
well, im gonna be working on my launch. hhmm nitto DRs.. sounds sweet. i am getting that Kenny Brown IRS brace. it should be coming in the mail pretty soon.cant wait for that one. i think that should help the 60ft time a little also. i think i might of been spinning my tires too much on the launch.

You may be running too rich up top and losing power, and it seems you are waiting too long to shift. If I remember other graphs right, the Cobra's power starts dropping off around 6200 or so... I disagree with not working on the launch and patching the lack of experience with DR's. Even with DR's and guys who dont know what they are doing, I've seen them pull 2.0+ 60' times. I'd say practice till you can consistently cut 2.0 60' times, then get the Dr's. That way you'll have the technique down, and know your car well enough to know what kind of launch it wants/needs to get good times. I'd say you did a good job your first time out, what was the temp out when you went? Are you apart of LSS or AAS?

01BlkGT said:Nahm wasnt saying to shift at 6200rpms, I was more implying to get your car dyno'd so you can can figure out what your car's powerband is with you mods. This way you can see where your car's power peeks and you can figure out your shift points from there. Most importantly, have fun with it and dont think you have to run xx.xx @xxxmph or you suck. As with anything there is a learning curve and as you get more experience and learn the car more, your times will drop.

Hope that helps some.
billfisher said:dude, practive runs at different shift rpm until you get best ET. dont worry about some 'number' you are told to shift at. also if you heat the tires too long they turn into lubricant. I have overheated yokahamas and has to feather nost of the 1/8th. really sucked. don't try to focus on too many things on each run. i have a pre-stage routine. helps me to focus on the tree.

I talked to a guy that had a '65 Mustang coupe - ran 10.9 all 3 times that night, it was an awsome car... i hope to have mine looking like his did sometime in the next couple of years. We had a blast - the track is going to be my 2nd home!And, on the plus side - i finally ran into a Chevy (camaro) dude that wasn't a complete jerk-off... needless to say, i was suprised.
