Dyno testing a car costs money.  All of the Saturn owners who have participated in our club events and have chosen to dyno test their cars deserve our gratitude.  For sharing this information, we'd like to extend to them a big

Thank You!

Without their continued efforts toward improving their vehicles, and their need to objectively measure how changes affect performance, more of us would be buying parts based on biased advertising claims, hearsay, and faith.

Do you have parts that you'd like dyno tested?  The SPC will test products for FREE and will pay for return shipping. This offer is for anyone (manufacturers or individuals) who wants to verify the performance of any product. Please contact us and we will happily arrange testing!

General Testing Notes

• Not clear on exactly what a chassis dynamometer is and how it works?  You can find everything you need to know in this article that appeared in GM High-Tech Performance Magazine.
  
• All dyno tests currently in the archive were performed on a Dynojet Chassis Dynamometer.  Most dyno testing takes place at our club events or functions.  Graphs and data that you see in the archive were taken directly from the original data files using Dynojet WinPep 6.03 software with the smoothing level set to 3.
  
• The Dynojet equipment we most often use can have difficulty with certain types of aftermarket plug wires.  Because of this, some graphs of the archived runs may show incomplete torque numbers or obviously inaccurate torque readings.  Horsepower numbers are not affected by this.
  
• The graphs for some runs may show the wrong torque scale (doubled or halved) due to software settings that were not set properly during data acquisition.  In this case, disregard the torque numbers from the graph and refer to the numbers specified in the remarks.
  
• The Dynojet software adjusts data at the time of acquisition for variations in  temperature, humidity, and elevation.
  
• Don't put too much weight on differences between runs of one or two horsepower.  This is statistically insignificant and within the dyno's threshold of error.
  
• All vehicles in the dyno archive are manual transmission unless specified otherwise in the notes section.
  

Note to dyno testers: Have you found inaccurate / incomplete data or notes in the archive for your dyno runs?  Or would you prefer they be excluded, or your name made anonymous?  Do you have information to add that's not included?  Contact us and we'll be happy to make any changes.
