Kart DYNO mite Dynamometer

Standard dyno kits include: 7" toroidal flow water brake absorber (with 5" high-RPM rotor), electronic torque arm transducer, engine load control, DYNOmite handheld data-acquisition computer, AC power supply/recharger, stainless braided hoses, magnetic RPM sensor, data wiring harness, and protective carrying case.

DYNOmite data-acquisition electronics eliminate “wishful” paper and pencil hand-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 air temperature, barometric pressure, and relative humidity. Estimating power from hydraulic pressure conversion charts is not required. Neither is running an engine to death to get a full test curve. Keypad model DYNOmites display results on their LCDs, and can print to an optional portable ASCII parallel printer.

DYNO-MAX 2000™ Software option creates a full engine dynamometer lab console on your PC. Features include: real-time trace-chart graph display, EGT bar graph, inertia compensation, user adjustable visual and voice limit warnings, pushbutton controls, and user configurable analog and digital gauge ranges. With the optional electronic auto-load control (or electronic throttle) you can easily generate and execute complex race track road-load simulations, engine tests, or break-in cycles. Setting up a test is as simple as making a few mouse clicks, to set the test RPM points and desired sweep rate. Then, just allow the DYNOmite’s PID algorithms to run the whole show.

How does it work? The DYNOmite’s absorber is actually a very inefficient centrifugal water pump - with a variable flow control. The more water provided to the absorber, the more power this “pump” requires. It acts as a “brake” on the crankshaft. The resultant absorber housing torque and engine RPM are monitored by computer. During a test, the dyno operator regulates the engine’s RPM (by adjusting supply water via the “Load Control Valve”) to slowly sweep through the desired range. The DYNOmite calculates horsepower via the standard formula: Hp = Torque (in foot pounds) x RPM / 5,252.

Patented torque transducer technology is moment-length independent. Its temperature-compensated strain gauges, which measure true shaft torque and Hp, require no recalibration for changes in the support geometry. This simplifies fabrication of your own engine test stand or in-vehicle mounts. Pushbutton, semi-automatic offset for the zero calibration point is also standard.

30+ Hp* capacity with our standard toroidal flow water brake absorber (or 60+ Hp* using high torque rotor). The toroid’s ultra-low volume design provides control stability and response unmatched by simple vaned brakes. Loads typical kart engines from a garden hose water supply.* (Many other size water or eddy-current absorbers available to test virtually any capacity engine.)

Direct crankshaft mounting on most engines eliminates any “factoring” for drive-train losses! The 5" (or optional 7") rotor’s arbor fits directly onto standard ¾" diameter 3/16" keyed shafts. An optional 9" absorber fits 3° (1:10) and 4° (1:7.5) tapered PTO’s. Where clearance is available, engines can be tested right in the vehicle's chassis – using an optional rear axle adapter.

Precision designed and manufactured for flexibility, strength, high accuracy, and reliability. Each water absorption brake, torque arm, load-valve, etc. is beautifully CNC machined out of anodized aircraft billet aluminum and 17-4.

Advanced standard features including: “Smart Record™,” data dampening, spike filtering, playback data averaging, SAE atmospheric correction, instant data playback, torque auto-zeroing, and an integral rev-limiter.

Small Engine Test Stand option adapts to many ATV, chain saw, kart, motorcycle, snowmobile, PWC, and industrial engines. Rugged steel construction – with universal engine mounting plate, rubber vibration isolation mounts, battery compartment, integral accessories shelf, removable (stand or wall mount) engine control console, wheels, leveling pads, and openings for installing our optional engine throttle and load controls. Mounting plate accepts many engines but can be drilled for unique custom applications or to accept “pillow block” type jackshaft bearings. Optional overhead “skyhook” boom supports fuel, electrical, and exhaust systems. Fan cutouts in the lower section are provided to allow eddy-current absorber cooling.

Schools teach engineering principles using accurate and repeatable (yet inexpensive) DYNOmite small engine dynamometers. They are used by both private and public colleges, as well as technical schools - around the world.

Develop faster karts by separating what does work from what should stay on the shelf - with less trial and error. In hours (rather than seasons) you can find those tuning combinations that keep top racers out front.

Increase profits by selling dyno tuning while enhancing your shop’s engineering image. You can even display the DYNOmite to potential customers as advertisement.

Affordable upgrades including: 5-gas exhaust analyzer, thermostatically controlled cooling tower, fuel flow and airflow turbines, “Weather Station,” EGT (exhaust gas temperature) thermocouple kits, RTDs, sparkplug/head thermocouples, pressure transducers, knock sensors, temperature thermistors, auto servo load and throttle control.

Live-person technical phone support (from those who revolutionized small engine dynoing) beats other companies’ obnoxious “voice mail” runarounds. Our standard hardware phone and e-mail support, plus access to the special DYNOmite owners 24/7 web support area, are all FREE!
