D-557 Dynamometer
1000 HP (746kW) Maximum Power,
700 Lb-Ft (1,017Nm) Maximum Torque,
10,000-12,000 rpm Maximum Speed
The D-57 series dynamometers can be used both with diesel and
gasoline automotive engines at speeds up to 7,500 rpm continuous
and 10,000 rpm intermittent. The D-57 is designed to be quickly
and easily fitted to an engine mounted on a fixed base or mobile
engine stand. The ease of use, when combined with a Go Power
Systems instrumentation package, allows the user to achieve
precise testing and results with a minimum of set up time.
There are a wide variety of adapters and engine carts available
which will allow attachment to all standard engine types. Go
Power Systems engineering can readily design adapters for
virtually any application. Go Power Systems has available
cooling columns, engine carts, engine adapters and many other
options and accessories necessary to outfit test cells from the
entry level to the most sophisticated automated data acquisition
control systems.
