    took the cobra to the track for the first time and ran her down the 1320 six times. might have gotten a sevemth if I had stayed but didn't want to get greedy and we were tired as it was. Atco raceway, NJ. One other SN95 rio red convertible there, didn't even approach me.

    all runs were made with the rear tire pressures as close to 20psi as I could get them. Nothing extra in the car that wouldn't have rolled off the factory floor. spare and jack, rear seats intact, etc. ran the car on less than 1/4 tank of 93 octane. I did not do any burnouts and I cleaned off all debris in the waiting lanes in between runs with a hard bristle brush. the car never got above normal coolant temperatures or ran poorly, made any sounds, etc. and nothing broke so I am very pleased.

    1st run - first car to run on the track all day, I didn't want to go through the water box and "illegally" went around it and got hollered at...whatever...at the end of the day we could tell it would have been better for me always to go around it if they would have let me.

    R/T .797
    60' 2.179
    330' 6.114
    1/8 9.625
    mph 71.98
    1000 12.471
    1/4 14.867
    mph 94.63


    just basically sat there and waited until I felt comfortable, got a great launch felt just like on the street. slipped it from 2500 and went. missed 3rd gear, shut it down.


    2nd run - tried the same launch, track had heated up and had some serious rubber on it now from some pro street crowd, absolutely hooked and bogged.

    R/T .682
    60' 2.375
    330' 6.306
    1/8 9.513
    mph 77.64
    1000 12.234
    1/4 14.525
    mph 99.09



    3rd run - same idea, finally got the tree down, although that was the last of my worries today



    R/T .199
    60' 2.333
    330' 6.261
    1/8 9.456
    mph 77.69
    1000 12.141
    1/4 14.390
    mph 100.73



    4th run - knowing the track is really hot and thinking I only may have one more run, I want to go all out and aggressively slip/almost dump from 4000rpm. when I go up to the tree, they now have a cone blocking me from putting it into the groove, so I am forced to run where the hot sticky rubber is not...1st is useless, I hold it spinning at the redline until they finally hook, then grab second with a bark.

    interestingly, I learned the most from this run. I had been shifting at 5500 rpm, and into fourth at about the 1000 mark. When I first got the car, I would race it up to 6500 rpm, because that is where it felt fastest. after running my friend's STi, I learned I am "supposed to" shift around 5500. after racing him again, we both thought it made a noticeable improvement. frustrated at the bad launch and not really concentrating, I half-mindedly let second gear go to 6500 rpm and took third all the way through the traps. look at the speeds, huge difference in the car. way higher trap speed. all further runs were made at shifts around 6500 and finishing the traps in 3rd.


    R/T .711
    60' 2.510
    330' 6.463
    1/8 9.590
    mph 79.03
    1000 12.233
    1/4 14.451
    mph 102.02


    5th run - best of the day - good heads up race - shooting for 13's, this run convinced me the car easily has a 13 in it.


    R/T -.272
    60' 2.285
    330' 6.094
    1/8 9.209
    mph 79.14
    1000 11.853
    1/4 14.078
    mph 101.68


    6th run - major distractions, late night, lights on - cut another decent light, another decent launch. I've come to accept the 2.1 was a fluke since I was allowed to get into the groove on that run, which they did not let the street-tired cars do for the rest of the night. high 2.2's aren't bad on the crap I have to run with, I'd like to start getting consistent .2xx reactions and low 2.2 60's.


    R/T .278
    60' 2.299
    330' 6.124
    1/8 9.265
    mph 78.85
    1000 11.920
    1/4 14.146
    mph 101.55




    some pics of me and rich. 04 STi, cobb catted 3" downpipe, heat shield, catback, axxisport tuner, AEM intake, Bride replica seats...fastest run was 13.3 I believe, having a lot of wheel hop issues.

    Since that is a Cobra your shift points should be somewhere between 6500-7000(redline). I haven't drove it, so try turning a little more rpm and look for mph (like before) et will come with traction and practice.

    whhhhooooo those 60fts are pretty bad :( some DR's would help a bunch. Just keep going back and get the hang of the rev launch and you will cut those ets down.

    yeah, the only one that felt really good was the first one, felt like what I can do on the street where it just chirps and goes. we'd both like to get the car into the 13.8's or high 13.7's with some more practice on the mods we have, because if I can't learn to drive this thing as is, as we do the power mods the car is just going to start getting dangerously out of control. I was very annoyed that I coudn't go around the burnout box or use the groove, considering I was being so anal about keeping my tires and the track so clean. :lame:

    and drag radials means breaking things. :-(

    I have been running on DR's for 5 years and NEVER broke anything :angel: I ran them on my 91GT / 98GT / and now my 99 Cobra. I dont come off at 5k with them so im not in danger of breaking, but they do a lot better than street tires. Put a set on there and come off at 2500 you will DEAD HOOK :boink:

    oh yes BFG DR's is all I have ever used :boink: I ran 275's on my 91 / 98 but I have 315's in my 99 Cobra :khobra: The only down side is in the rain, they are a little fishy so you have to be carefull. Other than that they are great, hook like fly paper. I get around 5k miles out of mine, so they dont last forever......but the payoff from them is well worth the short life span they have.

    I run a 275/40/17 BFG drag radial on my '95 GT and I love it. I have only been able to race on a track once, and that was a week after buying my car. I managed a 2.1 sixty, hopefully with a little practice, I can hit 1.8's atleast :) What mods do you have?

    yeah I know what you mean about rain, even worse on a fwd...

    we'll probably wait and pick up a set of lightweight track dedicated wheels to mount them on as we usually take 2 cars anyway.

    I was thinking prostars. I was not aware of another possible heterosexual performance wheel selection for an sn95. :dunno:

    :)

    probably going to do something different to stick out though. powdercoat them maybe.

    I'm a big fan of Rodlites on a fox, but I believe if I was to ever get Welds for my '95, I'd be Prostars.

    Then again, Bogarts > Welds
