* Static boost pressure at the dyno was -0.63 PSI.  This means an extra +0.63 PSI was added to all boost readings used to calculate average boost.

Conditions:

  • Temparature:: 83.47 degrees F
  • Atmospheric pressure: 29.22 inHg
  • Humidity: 9%
  • SAE Correction: 1.01
  • STD Correction:  1.03
  • Uncorrected: 1.000

Results:

  • SAE Corrected: 516whp @ 8330 RPM, 330wtq @ 7410 RPM
  • STD Corrected: 527whp, 337wtq
  • Uncorrected: 510whp, 326wtq

Individual Dyno Results:

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.
