Dyno Graphs:
Horsepower, Torque, AFR, and Boost
Horsepower and Torque are SAE Corrected using Kestel 4500 weather station. AFR is collected from a Bavarian Technic tool connected to the OBD port. These values are read from the ECU and are exactly what the ECU saw. Boost is collected from the Dyno files.

Dyno Database:

Individual Dyno Results:

Individual dyno results are shown below.  SAE corrected results are shown twice, using two different sources.  The first source (SAEd) are the SAE corrected results straight from the Dynojet.  The second source (SAEk) of SAE corrected results are obtained by using the Kestrel 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
  • 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.
  • Temp(F) = Temperature (Farenheit)
  • RelH = Relative Humidity
  • Pressure(Hg) = Barometric Pressure
  • DA(ft) = Density Altitude
  • 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.
