OK...so I went to my local 1/4 mi. track last night too. I got in 6 runs. I hardly spun my wheels/tires at all, but I have 19" Mich PS2s.
What a fun time; my best time was 13.097 sec. @ 106.67mph (w/ a 60ft. time of 1.977 sec.). My fastest trap speed was 107.29mph, but on that run, I did 13.171sec.
I know I could get into the high 12's (~ 12.8-12.9 sec.) with better weather and track conditions...it was 84 degrees F w/ ~ 65% R.H...the air was so thick last night, you could cut it with a knife.
I'll scan in and post up my best timeslip next week.
In regards to my Beltronics FX2 -- I tested it last night at the track, and it was off by less than 2/10ths of a sec., but.....it was SLOWER than my actual track time.
So, Kujo is right and wrong, at least for MY specific FX2 unit. It showed 13.2 sec. when the track timeslip shows 13.097 sec.
Anyhow, it was my first time at the track...a lot of fun, and I was happy with my results. I can't wait for PROcede v2.0. :rocks:
btw -- my brother ran his Lotus Elise w/ Nitrous (and intake) and his best time was also 13.0xx sec., so I was just as fast as him with Nitrous and an intake.
Also, most of the other cars -- a GTO, VW GTIs, Mustang GTs, Acura/Honda ricers, etc. were all running in the 14's-15's; even a Mitsu Evo ran ~ 13.8sec.
