D57 Series Dynamometer System Packages

As with all the Go Power dynos, the D57 series can be purchased as an individual unit or as part of a complete test package: 

D57 Series dynamometer package

EDP57 Essential Dynamometer Package

The EDP357/557 Essential Gasoline Dynamometer System Package is a portable gasoline engine dynamometer  package consisting of:

  • D357 or 557 Dynamometer (see above for details)
  • Torque calibration arm assembly (metric or imperial, weights not included) (Note: dyno should be calibrated every 6 months)
  • Manual load control valve set
  • DC200 digital display console. Read more about the DC200
  • Interface harness kit 

The EDP is perfect for the gasoline engine tester that does not require a data acquisition system but is looking to simply get readings on RPM, Speed and Torque. If an actual data acquisition system is desired, the ADP package (below) would be appropriate.

The ADP357/557 Advanced Dynamometer Package includes all of the components listed in the EDP package, except the GPS6000 Data Acquisition System is supplied in place of the DC200 Display Console. This package contains:
