Wow, those are pretty bad. I did not do too well my first time too.
My best time was a 16.1 at 88mph. Also got 16.4's I had 3 runs.
My second time at the track, I did a little better 15.8 at 89.6mph with a 2.57 60ft. Also, 90+ deg. temp. dont help. Still I was dissapointed with the times especially the 60 foot which is the key. What was yours? What tires due you have?
Also, what rpm due you shift at? With no launch at all, I got 16.4(No whelspin, normal takeoff). Even with a bad launch you should get in the 15's. Dont worry the second time you will due much better
