I have seen almost all "BPU" Zs run at least low 13s even in 100 degrees at pomona, except for a few with other problems and maybe full cats. On the other hand I've seen many bpu supras run 14s at the same track. :-). Just mentioning my experience.
: doing so hot. Yea too bad about the temp. I gotta go to Sacto Raceway and check out some supra runs when they hold a track event here again. Haven't been to the track for awhile since I not to big on 1/4 mile times but still interesting to see their potential. BTW, what does your Supra run?
