Definitely sounds fun. We are doing a similar test to try and accuratize the dyno. We plan to mark out 1" increments on a floor for about 4-5 feet. Then we will run a car full speed and take video. Then I will view the video frame-by-frame and calculate the average distance travelled per frame. Multiply by 30 (30fps) then convert to MPH. Then we plan to add weight on the dyno rollers until we can achieve that speed on the dyno with the exact same car.
Now, while not a perfect calibration, it will be the closest thing available to our community!
I'll also be doing a write-up on how we modified the dyno to hook to the PC, the circuitry to keep the LCD accurate after the mod and the weighting process.
Too much stuff to do and not enough time to do it in!!! <sigh>
