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 inertia compensation and SAE correction factors for air temperature, barometric pressure, and relative humidity. No running an engine to death getting a full test curve. Results display on the DYNOmite’s LCD and can be printed to an optional portable ASCII printer. The handheld computer can even do double-duty as a highly advanced on-sled racing data recorder.
Integrate your own PC using DYNO-MAX with appropriate automated electronic load and throttle control hardware options for keyboard dyno control. Without special programming, operators can easily create and execute complex race simulations and engine test cycles. Patented torque transducer technology is immune to temperature changes and the length of the moment-arm (anti-rotation point). So, it requires no correction for jackshaft center distances. Pushbutton (semi-automatic) zeroing of the torque offset calibration is also standard. Reads TRUE crankshaft Hp using precision full-bridge (temperature-compensated) strain gauges to directly measure actual torque, instead of estimating from hydraulic pressure or inertial acceleration. Only crankshaft dynamometers isolate Hp from the inconsistencies of belt efficiency, track tension, windage, etc. to provide the repeatable data serious developers need to compare against the OEM’s and other engine builders’ results.
Precision designed and manufactured for strength, accuracy, and reliability. Each water-brake absorber, torque arm, load-valve, etc. is beautifully CNC machined from anodized aircraft billet aluminum and heat-treated 17-4 stainless steel. Advanced standard features including: Smart Record™ test-recording trigger points, data dampening with spike filtering, auto-zeroing, instant playback, adjustable graph-data averaging, atmospheric correction and integral adjustable engine rev-limiter. Everything gets tested, right in the sled, the way you run it. Evaluate air- box flow, throttle travel and oil-injection-cable adjustments, fuel-delivery system, exhaust routing, motor- mount play, vibration problems… everything. Develop quicker sleds by finally pinpointing the optimum RPM range for every horsepower gain (or shift). Evaluate components, tuning changes, durability, etc. Learn things “you never knew – you never knew.”
Easy test set-ups by mechanics with little, or no, dyno and computer experience. Even run outside, without an expensive dyno-cell ventilation system. Just remove the sled’s clutches, bolt the DYNOmite to the PTO, hook up a few wires and hoses, and test (without spending hours swapping a dirty suspension). Go right from riding, to outputting Hp data, in less than 15 minutes. Automated load control simplifies steadying the peaky snowmobile engines, it reacts faster to sudden torque changes than most humans can. Our optional electronic-servo load valve replaces the standard manual-load control. Once installed you use buttons to select the test RPM, or sweep rate, and then let the computer do the rest of the work. Affordable upgrades including: thermostatically controlled cooling tower, jackshaft RPM/MPH sensors, fuel-flow and airflow turbines, AFR modules (4-strokes), clutch efficiency dyno conversion, weather Station, EGT (exhaust- gas temperature) thermocouples, pressure transducers, thermistors, and both servo load and throttle control options.
Specialty dynamometers for sled testing are available as both production and custom systems. As you can see on these pages, we manufacture more types of dynos than any other company in the world. Are you looking for a drive-on track model for quickly running-in stock snow machines, a CVT dyno for designing clutches, an AC dynamometer for advanced R&D lab emissions testing, or a 600 Hp 12,000 RPM Siamese-rotor absorber for asphalt-drag engine dynoing? If so, we can help you. Live-person technical phone support, from our true snowmobile dynamometer testing experts, provides a significant advantage over other companies’ obnoxious voice-mail runarounds. Land & Sea’s employees enjoy riding, racing, dynoing and talking sleds. Note: Your standard hardware phone and e-mail support, plus 24/7 access to the DYNOmite owners web support area, will all be FREE! Free DYNO-MAX™ "Pro+" Demo TourFree DYNO-MAX "Pro+" Multimedia Demo Tour... shows how our optional software turns any PC or Laptop into a dynamometer console! Demonstrates real-time engine displays and controls, Formula Editor, graphing of multiple pulls, and Smart Print™ engine report generation.
