The Engine Masters Challenge has done more than just bring a few new engine builders into focus. It's created a whole new market for racing engine dynos and Dynamic Test Systems (DTS), the official dyno system used in the EMC, have taken that subject to a whole new, exciting level. Now, whether your shop is huge, or you're running engines on a homemade stand in your backyard, you to can have an official Engine Masters Dynamometer System!
The EM-2000 has dual water valve control, a built-in starter, an engine docking cart, and industrial-grade design and construction for superior reliability. The EM-2000 is the only dynamometer to feature cross-vented rotor design, which relieves internal pressures to allow faster and smoother water flow. Along with its unique porting and vane design, the EM-2000 is the most accurate water brake in load control. It gives you smooth, fast control during sweep/acceleration testing and finite steady-state rpm control for mapping and endurance testing. EM

The absorption unit, shown...
The absorption unit, shown here with twin starters, is what determines the power rating of the system and basically tells you how much power your engine is making.

A great feature about the...
A great feature about the DTS dyno system, and one that makes it possible for us to run so many motors in a single week in the Engine Masters Challenge, is its "docking cart," allowing you to bolt the engine up ahead of time, and then roll it into the cell.
BASIC WATERBRAKE DYNAMOMETER PRINCIPALS
A dynamometer measures engine torque by transforming the rotating torque at the crankshaft to stationary torque. The stationary torque can then be measured with a scale or, more precisely, a strain gauge.
A waterbrake has vaned impellers (rotors) attached to the mainshaft. The mainshaft is then attached to engine's crankshaft. So the rotor/mainshaft assembly spins at the same rpm as the engine. The impellers rotate within an enclosed watertight housing. The inside of this stationary housing also has vanes. When water is induced into the housing the rotating vanes force the water against the stationary vanes. This force causes the stationary housing to try to rotate and also applies resistance or load to the crankshaft. The more water allowed into the housing, the more load is applied. The entire housing assembly, better known as the absorption unit, is suspended in a trunion assembly that supports the unit and at the same time allows it to rotate. To stop the absorption unit from completely rotating it is restricted by a strain gauge that measures the force trying to rotate the absorption unit. This measured force directly correlates the amount of rotating torque being "absorbed." The energy of the torque and rpm is converted to heat and carried away by the water flowing through the absorption unit. The size of the absorption unit and number of rotating impellers determine the torque absorption capabilities of the over all assembly.
