Dyno Database:

Individual Dyno Results:

Individual dyno results are shown below.  SAE corrected results are shown twice, using two different sources.  The first source (djc) are the SAE corrected results straight from the Dynojet.  The second source (sae) of SAE corrected results are obtained by using the Kestral 4500 weather station data for each individual dyno run and running it through an independent SAE correction formula.  This ensures that the dyno results are accurate and can be independently audited and verified for authenticity and accuracy.

The legend below has the following meaning:

  • Dyno Run:  Dyno run file
  • Timestamp
  • Temp(F) = Temperature (Farenheit)
  • RelH = Relative Humidity
  • Pressure(Hg) = Barometric Pressure
  • DA(ft) = Density Altitude
  • IAT = Intake Air Temperature
  • Oil(F) = Oil Temperature (Farenheit)
  • O2(F) = Water Temperature (Farenheit)
  • WHP(unc) = Uncorrected wheel horsepower
  • WTQ(unc) = Uncorrected wheel torque
  • WHP(SAEd) = Dynojet SAE corrected wheel horsepower (SAE-1340 PRE-2004)
  • WTQ(SAEd) = Dynojet corrected wheel torque (SAE-1349 PRE-2004)
  • WHP(SAEk) = SAE-Adapted wheel horsepower (SAE-1349 2004+)
  • WTQ(SAEk) = SAE-Adapted wheel torque (SAE-1349 2004+)
