Click to dynamometer prices.Land & Sea’s DYNOmite PWC Dynamometers measure true installed horsepower… without removing the engine from the hull. The DYNOmite simply replaces the pump nozzle housing. Say goodbye to ambiguous thrust tests.

“Eliminate frustrating tank testing and service trips to the water.”

Click to enlarge pwc dynamometer kit.Standard dyno kit includes: 9" water brake absorber, electronic torque arm transducer, engine load control, DYNOmite handheld data acquisition computer with LCD interface, AC power supply/recharger, stainless braided hoses, puller bolt, data wiring harness, and protective carrying case. (Note: the required pump-to-absorber adapter assemblies are sold separately.)

How is it used? Mount the DYNOmite absorber (and appropriate pump adapter) in place of the boat’s standard nozzle and cone. Each adapter incorporates a shaft, driven by the impeller (without impeller removal). A load control valve (fed from your ¾" garden hose) lets you regulate RPM by varying absorber drag (while holding the throttle open). You can simulate running at any MPH from idle to top end. The DYNOmite’s computer calculates and displays power with the standard formula:
         
Hp = Absorber Torque (in foot pounds) x RPM / 5,252

Click to data acquisition software page.DYNO-MAX 2000 Software option creates a full engine dynamometer lab console on your PC. Features include: real-time trace graph display, EGT bar graph, operator adjustable voice and visual limit warnings, inertia compensation, pushbutton controls, and operator configurable analog and digital gauge ranges. Data, reports, and publication quality graphs can be printed for your customers – in full color.

DYNOmite Data Acquisition Electronics eliminate paper and pencil data logging. The DYNOmite computer records true Hp, torque, RPM, elapsed time, etc. (at up to 1,000 readings per second) while automatically applying SAE correction factors for the air’s temperature, barometric pressure, and relative humidity. Results display on the DYNOmite’s LCD and can be printed to an optional portable ASCII printer.

Integral torque transducer uses precision temperature compensated strain gauges to directly measure engine torque. Pushbutton, semi-automatic offset for the zero calibration point is also standard.

Reads true impeller shaft Hp beats trying to estimate the engine’s power and performance from inconsistent tank pull “thrust” tests or pump nozzle pressure readings.

Pump adapter assemblies (available separately) let you move one DYNOmite among numerous models of PWCs (and snowmobiles too). Test most production watercraft engines from your ¾" garden hose water supply.*

Precision designed and manufactured for strength, accuracy, and reliability. Each water absorption brake, torque arm, load-valve control, pump housing adapter assembly, braided hose assembly fitting, etc. is beautifully CNC machined from anodized aircraft aluminum billet and heat-treated stainless steel. Even the fasteners are stainless, for maximum corrosion resistance in a marine environment.

Everything gets tested, right in the hull, the way you run it! Evaluate air box flow, throttle adjustment, fuel delivery system, exhaust routing, motor mount vibration problems, pump alignment… EVERYTHING.

Develop quicker watercrafts by pinpointing exact RPM locations of horsepower loss or gain. See just which components work, what tuning changes help, how modifications effect durability, etc. Even map out the optimum “variable water flow” exhaust set-up for each RPM point.

Profitably troubleshoot off the water and avoid wasting valuable time trailering around to test. Why run up non-billable hours separating owner’s imagined power losses from real ones? Even customers who normally whine over charges for lake testing willingly pay extra for dyno time (when it includes a printout). Dealers find that just displaying the DYNOmite enhances the shop’s image (and supports higher labor rates too)!

Easy test set-ups by mechanics with no dyno or computer experience. Simply replace the pump’s nozzle and cone with an appropriate pump adapter assembly, bolt the DYNOmite to the adapter, hook up a few wires and hoses, and test. You can run it outside without an expensive dyno cell ventilation system. Eliminates the hassle of getting the boat into the test tank or to the ramp.

Automated load control using the optional Electronic Servo Load Valve (to replace the standard manual load control). Just push the buttons to change the test RPM, or select a sweep rate, and let the computer handle the rest of the work.
