Hey guys, okay first of all my car is a 99 trans am with of lt headers, 3in exhaust with no mufflers dumped, lid, I also removed the filter for these runs and regular street tires and my raceweight was 3620. Here is my time

60 2.23
330 5.878
1/8 8.84
Mph 82.78
1000 11.36
1/4 13.49
Mph 105.83

I am not sure what the da was but this was at 10.25pm in noble Oklahoma and it was about 85 degrees. I have ran a 13.1 at 112 before in much colder air. So my question is, is something wrong here or do I just need better air and a better tire? I am purchasing some nitro 555rs next

 

Nothing wrong. It is Summertime. Better tires & air will get you into the 12's. Good luck.
