    Where did you dyno at? I dont know what it should dyno but i think 108 sounds kinda weak for your mods and dyno #'s though, i would think you should be around 11.80's or quicker @114 or so mph w/ you mod list :shrug:

    I dynoed it at mc racing in merriam ks.108 mph were before the computer chip but i doubt the chip made that much difference.what affects mph in the quarter other than hp???i was on hoosier slicks but only launching at 2500 rpm and granny shifting
