The new Black Widow from SuperFlow is a breakthrough in versatility and performance among water brake dynamometers. With a speed range from 1,300 rpm all the way to 11,000 rpm (intermittent), the Black Widow handles anything from high-torque marine engines to high-revving drag engines. Our engineers have taken careful steps to ensure that the Black Widow comes with the legendary accuracy, repeatability, and control that all SuperFlow dynos are known for.

The next generation of dynamometer software is here. Users told us they wanted software that was easy to use and completely customizable, and we listened. WinDyn 3.1 has our standard predefined test groups to get you testing quickly, but we've also added a new Microsoft® Windows®-based configuration editor that allows you to create custom test profiles, screens, controls, and limits easily and without any programming knowledge.
