what do you think i will run??? i have a 2001 rcsb silverado 2wd 4.8. my mods are-outlaw cold air intake, ls1 fans, pacesetter lts and ory, hooker muff dumped, 216/220 comp cam,2800 stall, built 60e(shift kit, servos,cluths bands, valves) eaton positrack, 4.10. hp tune.. thats it i think. i did some weight reduction(spare tire, jack etc)
the weather should be in the mid 80's.


so what can i look for?


thanks robert

 

High 13s, lower if you have some type of tires on it.

 

My guess would be some low 14 s w/the 80 degree weather . Hope u can hook on the street tires. Good luck..

 

im going with a 13.8-14.2

 

13.9@99

 

yeah try 15.002 and 15.05. yeah i think i need a professional turner. the truck is still shifting at stock specs. yeah vey very unhappy.

 

something's really wrong with your tune. i did that with just tuning and 4.10s with 1 tire fire.

 

yeah i only have the 4.8 but damn

 

Yeah, that tune is hurting you...could you post up the times 60ft 330ft 1/8 ect...You need to get that thing dyno tuned. You should be about a second faster.

Also, what was the time and track you raced at, so we can figure the density altitude...because that can play a big role.

 

reaction time was .3 something and 60ft was 2.4ish

the race track was wichita international raceway
