SF-Powermark
High capacity, water brake engine dynamometer
The SF-Powermark features a rugged and durable power absorption unit with a 2” diameter main shaft machined from solid stock 17-4PH stainless steel and it's the only absorber available with cross vented rotors for smooth and fast water flow. Integrated starters are built into the system so a bell housing, flywheel or engine starter is not required. A torsionally compliant driveshaft connects the engine to the dyno enabling you to run right off the engines crank shaft while 4.5” constant velocity joints ensure smooth power transfer. The included roll around engine docking cart offers great versatility to adapt to various types of engines and its stainless steel runners mean easy adjustment of the engine supports without any rust. It’s also compatible with the SF-902S to allow maximum versatility. The tool tray has cutouts for storing spark plugs and lambda probes; it's also a convenient area to mount ignition system components. To keep the test cell neat, the integrated boom assembly houses both the sensor box and cooling tower, plus it has cable stays to route transducer wires cleanly between the sensor box and the engine. The included non-pressurized cooling tower mounts to the boom assembly behind the dyno, out of the way. The new sensor box also mounts to the boom and includes 4 liquid crystal displays (LCDs) to view any channel from the WinDyn® software system. WinDyn's® pre-defined test sequences allow for standard tests at the push of a button so you’re up and running immediately. The test editor allows you to write any custom test you prefer with ease.
