If I had to guess, mid 14's, maybe low 14's. But lots of variables in there, elevation, weather, track prep, etc.

i'd say mid 14's as well. Depending on tires, you might get a low 14 outta it.

14.8-15.1
I would set a goal of a 14 anything but don't be supprised if you stay in the 15s.

well thats the shitty part i got a fuel problem cant get the fuel pressure i need,absolutely did everything everybody told me to do and a fuel pump regulator the whole 9 yards and ran a 15.41 pretty shitty nothin was consistant u could feel it sluggish the whole way down the track and never went over 90.24mph so i was pretty pissed cause everybody i talked to before i did this was sayin i should be in the mid to low 14's and with the slicks high high 13's

what pressure are you seeing at the rails?

the stock pump should be fine if thats what you have? so you got an external fuel pump?

gettin 44psi at the rail talked to a gm tech said i should be gettin between
58-60 its lean as f#ck when u pull the plug he said the pump should be pullin 8.8 amps when u cross the fuel pump relay and check it there and mines pullin 14.4 he said i have a bad ground but all my grounds are good and im on my second pump just cause maybe the first was bad idk its got everybody stumped
