You could use that as well to record your sessions. Really enjoy your test articles. Thanks.

I didn't note the speed very often, and only recorded time and other tire parameters after the test was complete. But doing some calculations I put the times at roughly 54 and 91 mph, respectively. In the meantime, I have done extensive testing on other Skip Barbger setups which have resulted in better speeds, times, and G's, but this was just getting my feet wet in the testing. The formula for converting lateral acceleration and radius into average lap speed is: Speed [mph] = (49.065 * Lat Acceleration [G] * Radius [m])^0.5 To go the other way: Lateral Acceleration [G] = 0.020381 * (Speed [mph])^2 / Radius [m] And as I mentioned in the other tech tips story: Lateral Acceleration [G] = 4.026* Radius [m] / (laptime [s])^2 Keep the questions and comments coming! Lincoln,

I might try doing some tests on that skid pad too. Very nice job Ray! I might try doing some tests on that skid pad too.
