Made my way out to Dallas Raceway this afternoon for some 1/4 passes.
2000 RCSB 4.3 S10: Intake, Tune, Built trans, 275/40/17 Nitto 555r's, 3.73's, spray
I had the bottle refilled before run and hide to idle for 20 minutes to bring the pressure up from 800psi.
I got up to the staging lanes and was ready to run. Took off pretty good with a 2.0 60'ft. Mid ways thru second gear, truck started sputtering so I let out of the bottle and got back in it. Pulled decent but sputtered more so I let out completly. It didnt even display 1/4, only 1/8, went 9.0 @66 lol.
Before the next run I heated up the bottle and purged the line a little better and managed a...
1.8 60', 8.5 @ 77, 13.7 @ 89 Super low mph lololol
Changed to a smaller fuel jet. It was bogging from being too rich.
Hotlapping every run with about 5 minutes in between
Full weight:
1.8 60'
8.4 @ 80 mph
13.3 @ 97 mph
Pulled spare and dufflebag of tools and spinning.
1.82 60'
8.3 @ 80 mph
13.2 @ 98
Seems I cant spray out of the hole, I have to wait for about 10-15 feet.
Overall, Im pretty happy with those times.

Mine probably ran 15.5 stock, good .7 tenths added for his. There are several trucks like mine that basically run that exact time, 75% dont.
