    Wanted - GTech data for hard launches

    I'm after some data from an accelerometer based performance measurer to try and see how the start point relates to the acceleration and speed for hard launches in the 0 to 60 style and thus standing 1/8th, 1/4, 1 km, 1 mile etc. Basically I want to see whether the launch follows the initial shape of the acceleration vs. time or speed vs. time curves and thus get the most accurate way of calculating it.

    I need an accelerometer based measurement device as they are much better for standing starts. My GPS device detects a movement in a 0.2s space so I need to interpolate. Easy for rolling speed as there's a near constant slope but not so at the beginning.

    All in the vein of saving money

    The RR I sold to Paul might have some data on it ;-)

      anyone? I've had to make some assumptions at this stage and I know that I'm getting over optimistic results. Without a G force logger I can't get an estimate of the transition from stationary to moving. It seems to be less than one data point on my 5Hz GPS so I'd guess that 0.1s is a realistic guestimate...

        I'll get you some. Just tell me what kind of data you want:

        Road speed vs time, g-force vs time, etc

          Speed vs. time is fine htanks, I can measure acc. if I want. Thanks
