New best ET is 12.06 @ 113 with 1.75 60' time.

Still dialing in combo - shooting for 11's. Need to get 60' times down. MPH is consistently in the 110-114mph range. ET varies from 12.0* to 12.3 depending on launch / 60'.



Edit:
10/13/07 - new best is 12.01 @ 113 on motor 11.31 @ 122 on 100hp shot
Nitrous system is an NOS top shot (sits on top of carb) - 150 shot coming soon...

10/26/07 track trip yielded a new all motor pass of 11.82 @ 114mph with 1.74 60'
- still don't have a solid pass with the 150 shot.
