Hey guys, below is my setup....tell me what you think about it....and what do you think my truck will run in the Quarter...thanx.

2003 GMC Z71, 5.3, K&N FIPK w/ "fab'd ram air" , BBK 80mm TB w/ Spacer "wooo", 30lb Bosch Injectors, Custom Exhaust: gutted cats,no muffler dual pipes, Transgo Shift Kit w/ New Built Valve Body, Eaton Locker w/ Richmond 3.73, Running 275/70/R15 Yokohama Geolandar H/T tires.

 

RC or EC? SB or LB? I ran 15.57 with similar mods in my RCSB Z

 

Got a RCSB, which my truck has outran a "supposed" 14 sec Nissan Titan

 

I would say 14.5 to 14.7

 

 

If it is standard weight I am gonna say 15.1-15.5

I highly doubt it will hit a 14.5 unless there is weight reduction done, the track conditions are perfect or there is more than meets the eye.

Beating a car on the street that is "supposed" to run something is not a good indicator of extimated 1/4mile ET. Hang out at the track long enough and you'll see cars runn wildly different times due to 60' and reaction time on the tree.
