Using Corner Radius Information To Go Faster

Speed is in mph and lateral acceleration is in g’s. Multiplying the speed (mph) by 1.46667 gets the speed in ft/s and multiplying the lateral g’s by 32.17405 gets the g forces in ft/s2. The radius of the corner then ends up being in ft. It is amazing how accurate this formula can be. In Exhibit 1 I used Google Earth to look at turn one at VIR and I drew a circle that has a radius of 122 ft.
