    It went 1.30 on that run, 3.39 to the 330ft
    Previous run was 1.21 and 3.42 to the 330ft

    I'm pretty confident in a 1-teen 60ft with some tweaking.

    Wonder if the difference was 1 pass clippingbthe 60ft with front tires and withother the rear. The 330 times are reasonable close considering the 60ft spread. Doesn't make since the pass 9 hun faster in the 60 would be slower in 330, unless the way car tripped the beam or you had to pedal.

    Car does a great job of going forward and slowly lift and ride........its not a straight up........looks like a fairly calm set down as well..........also looked close to getting the 330 with the rear tires

    GS Kubisch THE "CUT-UP" BUICK

    We started the day with a 1.22/3.47/5.36

    Shortened the launch ramp which only showed a .004 improvement in 60ft. But... it picked up .04 to the 330ft. From the video I can deduce that is was not tripping the 60ft beam with the lead side of the front tire but instead the back of the front tire or possibly the header collectors...

    That was 1.21/3.43/5.30

    Third run was a throw away but I moved the shift points a bit and it did go over 130 which I was really waiting for. We also tightened the front shocks in an effort to get an accurate 60ft for this run

    Being that the third run was no good we left it alone for the fourth which was...

    1.21/3.42/5.29 an again it went 130+

    For the fifth run I added one degree of timing and left everything else the same.

    1.30 (Definitely on the rear tires) 3.39/5.25 at 131+

    So the only solid 60ft number is the 1.22/3.47 pass...I'd love to know what that last 60ft was consider 1.30 produced a 3.39

    I'm still smiling...

    If I had to guess by the incremental, I would be putting money on.1.185, seeing you were 4 hun under by the 330' it had to gain at least 2 hun in 60'

    131 is a very impressive mph

    When do bars out the back start to become a thought?? I would imagine if the front would stay down a little there is a few hun more from the areo drag

    I know this has been a multi year venture that had you rethinking, and almost jumping ship. I'm glad to see you be getting some very positive and impressive results. Wish I could had been there to see it in person

    Wheelie bars will be a last resort. I really don't want to use them.

    That is for sure up enough to not click the 60ft with the front tires.

    How much air are you running in your rear radials........looks nice

    Tires were 18psi or so. Couple pictures show that I can add some air.

    And here's a shot to show it ain't always laptops and jet changes
