Hi Vincent. Excellent MPH! Traction should lower E.T. a good bit. Congrats!
What was the DA at the track?

Strong back half. Part of the low 1/8 mph may be from lack of traction getting started but it sure pulls hard last half. Some better tire and suspension work it will def drop et. Might need more gear to bring 1/8 up some

Re: New best times at San Antonio Raceway
Et timing? 1/8 et matches the 1/4 et when using the low end of the conversion factors. Typically i see 1.54-1.57 used as a multiplier to the 1/8 mile et. Faster cars with very strong top ends seem to use 1.54-1.55 while slower cars with less mph gain from 1/8-1/4 use 1.56-1.57.
Your car is showing it has strong top end pull. Just need to get the 60' down into the 1.6 range and you'll be mid 11's easily, and a 1.5 should be low 11's at 119 mph.

Re: New best times at San Antonio Raceway
Nice times. Like Orr said that back half is super strong. You just need to figure out how to launch the car. I have the same problem with my Skylark. I took it to Fontana yesterday for one pass. I need to sort out the launch. Mine is car #3000.

Re: New best times at San Antonio Raceway
It looks like if you can get the 60 foot down to 1.6's or so thats a low 11 sec or better car. Maybe get more mph if there are bugs to be worked out. I'm jealous.
