Individual Dyno Results:

The legend below has the following meaning:

  • Dyno Run:  Dyno run file
  • Temp(F) = Temperature (Farenheit)
  • RelH = Relative Humidity
  • Pressure(Hg) = Barometric Pressure
  • DA(ft) = Density Altitude
  • Boost Avg:  Boost calculated using trend line.  This is the "official" boost for this dyno run.
  • Boost Peak:  Peak boost observed on this dyno run.
  • IAT:  Intake Air Temperature
  • WHP(unc) = Uncorrected wheel horsepower
  • WTQ(unc) = Uncorrected wheel torque
  • WHP(SAEd) = SAE Corrected Horsepower using Dynojet weather station.
  • WTQ(SAEd) = SAE Corrected Torque using Dynojet weather station.
  • WHP(SAEk) = SAE Corrected Horsepower using Kestrel 4500 weather station.
  • WTQ(SAEk) = SAE Corrected Torque using Kestrel 4500 weather station.
