Anyway, the tunnel data on power to spin is rarely if ever published due to the very high percentage of the total value attributable to motor losses and the fact that the tire rolling resistance is contained in there as well. We found that by using the same tire and very accurately controlling for pressure we could get very repeatable 'wattage to spin' deltas in the San Diego tunnel.
I've had good success using the six component balance data from san diego to determine aerodynamic torque. Was there any reason why your team chose not to use these six component data?
