Cool iceman. I am not a big fan of Norcross at all. We have an area around here on Barret Pkwy that is unfortunately over ran with ricers, which isn't worth the wasted gas but it sure is fun to watch there faces when I stomp there butts.

ok, heres a little drag racing knowledge for you that will help you understand your slow times.
#1- 60 ft times are very important when reading your time slip because for every tenth,hundreth,or thousandth that you are off on your 60 ft time will translate into twice that at the 1/4 mile trap given you are running the same through out the whole run. for example when i ran 12.80 my 60 ft was 1.7, so to translate your time with a 60 ft time of 2.4 you are 7 tenths slower to 60 ft which translates at the 1/4 mile trap as 14 tenths which = 1.4 seconds. given that 12.80 + 1.4 = 14.20
#2- if thats the case you ask why did you run a 14.32, well the first time you ran in od and let the car shift on its own and given that it shifted below 6000 rpm with the holley intake you probably lost a little bit of your peak in midrange or on bottom end because you didnt send it to its peak power producing rpm. you ask then why maybe ran slower shifting out yourself, well the holley intakes are bad about reaching low end peak quickly and given this, you prolly shifted too late on bottom end. im running a 3 speed manual shift body c-4 and i have to shift out of 1st at 5000 rpm because after that its turning dead rpms which = nothing more than revs. in 2nd i shift out at 6300 rpm because anything higher its dead rpm. if i shift out at 6300 in 1st my 1/4 mile trap is 2 tenths slower than shifting at 5,000.
i run a 3.73 gear and your running a 4.10, you may be reaching your peak alot quicker and the only way to find out what the peak is to go put it on a dyno and find out where each gear stops producing piower and shift about 200 rpm before that mark. then go run it and see what your times are. or if you dont have the money then try shifting diffrent in 1st gear. compare the 2 tickets you ran already and tell me what the diffrence in the 60 foot times were and i can tell you more or better yet post them on here so i can see them and i will tell you where you lost your time at.

The first run I couldnt see the staging lights due to the sun and I forgot to shift it manually.
Ill try to scan and post the timeslips tomorrow after work.
