Planning a benchmark

Sun Apr 14, 2019 11:17 pm


I'm planning a benchmark and wanted to run this by folks:
  • enable Rex at 75% to handle power needed above 70 mph
  • maximum acceleration on straight, flat, road
  • record acceleration and speed using GPS
  • two passes in opposite direction
  • repeat pairs to look for loss
  • measure weight for mass at a truck stop scale
  • using roll-down coefficients and accelerations, calculate net HP
