    Track times and not happy

    Went to track on Sunday with DJ Taso and LT1maroand i did 4 passes cuz i need a helmet after i did my sub 14 passes.

    First Run:
    R/T .414
    60 2.181
    1/8 9.077
    MPH 78.39
    1/4 14.057

    Second Run
    R/T .368
    60 2.040
    1/8 8.861
    MPH 78.83
    1/4 13.842
    MPH 98.63

    Third Run
    R/T .703
    60 2.214
    1/8 9.196
    MPH 77.55
    1/4 14.215
    MPH 96.49

    Last Run
    R/T .753
    60. 2.198
    1/8 8.972
    MPH 79.16
    1/4 13.905

    Im upset with these times because the last time the car was at the track it was bone stock to the paper air filter. I did a 14.0 @ 99mph and that was with 2.73 gears. I was hping for 13.5 with all my new mods. I thought a CAI was good for .1 or .2 and the gear for .2 or .3 atleast. Why did I trap at the same mph? These were even better conditions that last time. It was like 43 degrees or so i think . Even with the nittos on I could feel the car slip out a little on the 1st to 2nd shift. Any ideas.

      Your 60 foot times are decent, especially the 2.0. Your MPH is awfully low though. You might have lost a tick of RWHP with the gear swap, but it should be over 100 with your mods. The CAI is good for ~10 hp or 1 mph, and the cutout...I guess it depends on where it is.
      Do you notice a drop/loss in power during the runs? When's the last time you changed your plugs/wires? Are those the same wheels you used on the bone stock runs previously?

        It just looks like he didn't included his 1/4 mile trap speeds on the first and last run. The other MPH he included is his 1/8 mile speed. The 98.63 MPH run indicates that your car is probably capable of at least a 13.60.

          OOps the mph for the first run was 97.75 and the last run was 98.66. I didnt know what was going on. The car seemed stronger than ever. My plugs and wires were changed about 1 year ago. I was finishing the 1/4 mile in 3rd gear right around 4400 rpm's. The 14.2 time was a pass with the transmission shifting on its own. All the other times i was shifting 5800. Man this has been bothering me ever since i got home from the track, i know the car has a 13.6 in her. GRRRRR

              HP from MPH (1/4 mile) = WEIGHT * (MPH/234)^3

              and

              ET from HP (1/4 mile) = (WEIGHT / HP)^.333 * 5.825

              Also take a look over on the timeslip database on ls1tech. There are plenty of people running in the 13.60 range with 98-99 MPH trap speeds.
