Do you have any mods? Are those drag radial runs or street tires?

Very nice. How consistently were you running. Since that's one of the hard things to do with LS4 cars. How are you liking your current front tire choice

They are drag radials and mods are CAI,magnaflow exhaust, LS6 Intake, D.T. Headers ,HP Tuned, TEP 3.29s . With a better burnout , Im sure I can get them to hook a better time.

Better than the Mickey Thompson ETs I had. I ran one 13.6 and two 13.7s @ 101 Mph. Before the 3.29s I was running 13.6s but in cold weather @ 103 Mph.

Do you think that you would get a cooler air charge by removing your driver's side headlight? I have seen people do it before, but I'm not sure how well it would work. Nice runs.

Nahhh..... I think the closest I will get on good DA would be a 13.3 maybe a 13.2.

Yeah a 1.8-1.9 would get you around a 13.1-13.2. No 12s on that setup. But great runs. I would think 13.6s would come out of intake exhaust tires and tune. So I think your leaving some on the table. A little practice and you should easily be 13.2.

Time for some more valve lift with all of that air flow.
I would either cam it, or install some gold race roller rockers from crane cams.
Even though your 60 ft times are hurting your ET, your ET is impressive! I am a little concerned with your mph though.. I would like to see 105 ish with your set up.
What Rpm are you shifting at and who tuned your car? Something is holding your hp back.

I'm curious too what kinda rpms are you pulling. At the end of your run. With the different gear ratio are you into third? At 100 mph.

Rocker arms and springs are definetly in the plans .

I was hoping better Mph too but didn't happen .

I'm shifting at 6100rpm on first and second. And as for who tuned it , it was tuned by the trans guy . He changed the gear ratio and shift points since they were at 6500 before . Need to get a really good tune on it for sure .

At the end of the run I has shifted in third gear and Rpm was around @ 4800.
