Today, Alekshop threw a dyno day at Newtech in Hayward, California. We had a pretty decent turn out and a few surprises. Alek collected the money, and I collected the dyno results. I'd say it went pretty smooth. Then at the end of the day, the dyno operator hooked up his monster Corvette and layed down an insane 885whp and 775wtq.
I brought my portable weather station with me -- the Kestral 4500. It's a very accurate device. For each dyno run, I collected the actual weather data in the dyno shop. Many of us noticed that the dyno results today seemed low. When I compare the dyno shop weather data on the dyno charts with my own, I think it seems that the dyno shop weather station on the dyno isn't very accurate (or isn't working correctly). In the chart below, I attempt to correct for that data. Using the SAE correction formulas (SAE J1349), I used my actual weather data to "re-correct" each of the shop results. The legend below has the following meaning:
- Name (DDB). The person's name, along with the Dyno Database entry. If you click on the link for the name, you'll be taken directly to the Dyno Database entry. From within the DDB entry, you can download the Dynojet dyno files and dyno chart. In the case of the Dodge Challenger, clicking the name will download the dyno files and dyno chart.
- 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(djc) = Dynojet corrected wheel horsepower
- WTQ(djc) = Dynojet corrected wheel torque
- WHP(act) = Actual wheel horsepower
- WTQ(act) = Actual wheel torque
