"On-Board" DYNO mite Rotary Torque Transducers

(603) 329-5645

Drive-line rotary torque transducers allow measuring the torque and horsepower on almost any rotating driveshaft assembly. Equipping a drive-line with these computerized wireless transducers allows on-the-road monitoring, recording, and printing of true engine output.

“Turns any vehicle into a rolling dynamometer lab.”

Standard On-Board kits include wireless electronic torque transducer equipped driveshaft yoke, tail-shaft pick-up coil, wireless interface module, DYNOmite handheld data acquisition computer, AC power supply/recharger, data wiring harness, and protective carrying case.

DYNOmite Data Acquisition Electronics eliminate “driver’s memory” data logging. The DYNOmite computer automatically records true Hp, torque, RPM, MPH, elapsed time, shift ratio, etc. at up to 1,000 readings per second. It can even be set to automatically apply SAE correction factors for air temperature, barometric pressure, and relative humidity. Using DYNO-MAX 2000™, results can be displayed on your laptop, or directly on a LCD equipped DYNOmite handheld - for printing to an optional portable ASCII printer.

DYNO-MAX 2000™ Software option creates a full engine dynamometer lab console or vehicle dashboard on your laptop. Features include: real-time trace graph display, adjustable limit warnings, voice alarms, pushbutton controls, and user configurable analog and digital gauge ranges. There is even an integral drag strip Christmas tree with special ET formulas. .

Built in “Smart Record™” allows automatic triggering of data collection without the driver manually activating the DYNOmite. Other advanced features include: data dampening, spike filtering, playback data averaging, atmospheric correction, auto-zeroing, instant playback, and integral rev-limiter.

Not “guesstimated” inertial Hp; the wireless transducer reads actual torque from shaft mounted strain gauges. Unlike simple accelerometer based devices that just back-calculate from elapsed time or accelerometer readings, the DYNOmite provides accuracy and repeatability that make testing meaningful. This is not a toy!

Unlimited power and torque on custom shaft installations to over 15,000 RPM (using special high RPM models). Standard transducers are available for vehicles ranging from tiny 5 Hp karts to 8,000+ Hp dragsters. Custom industrial and OEM installations available for almost any application. There is no torque application that is too high for a custom installation. If your shaft can handle the torque, the DYNOmite can measure and record it!

High-temp electronic components are used, for the rotary board’s hybrid layout (both thru-hole and surface mount parts), to optimize stability and size. This lightweight, state-of-the-art transducer uses no brushes, slip-rings, or batteries, and does not consume any horsepower.

Simple installation… just replace the forward driveshaft yoke with the included modified OEM yoke and transducer assembly for most automotive installations. The pick-up coil clamps onto the end of the transmission’s tail-shaft. Wiring consists of connecting each of the DYNOmite’s two tachometer leads and then plugging in the rotary transducer’s shielded data cable and its 12-volt lighter plug.

Dyno any rotating shaft assembly by equipping it with our unique wireless transducer. Get real-time monitoring, recording, and printing of true shaft torque and horsepower. No prior experience with computers is needed to get professional results.

How it works: The stock driveshaft yoke is replaced with the DYNOmite’s Wireless Rotary Torque Transducer assembly. These transducers use full-bridge strain gauges (temperature compensated) that precisely measure torsional yoke twist (resulting from engine torque driving the shaft). That measurement is converted into a digital signal by the transducer’s computerized electronics. This data is broadcast to the receiver pick-up coil (without any mechanical contact between the rotating transducer and stationary coil). Shielded cable connects the coil to the DYNOmite Rotary Interface Module (inside the vehicle), ready for recording and displaying the transmitted data.

Bells and whistles include options to capture: EGT, engine temperature, fuel flow, BSFC, forward and lateral Gs, distance, MPH, MPG, A/F ratio, transmission slip, shift ratio, oil or fuel pressure, atmospheric test conditions, 0-5 volt auxiliary inputs (for lambda sensors, etc.), and even GPS location (maps the vehicle’s position via orbiting satellites). Radio modem telemetry is available to broadcast track data, real-time, back to your race pit crew’s laptop.

Everything is dynoed… exhaust back-pressure losses, fuel starvation issues, ram-air efficiency, transmission drag, traction… so things are evaluated as you really run them. Dynoing the pro’s way catches problems that never seem to show in a conventional dynamometer cell.

Is it the engine or driver? End that question forever – with a full dynamometer printout at the conclusion of every race. Know for certain whether increasing ETs or lap times are due to the engine going away, chassis set-up, or driver.

Mapping fuel injection or digital ignition curves is a “piece of cake.” Just tweak your map, push the pedal, and you instantly have the dynamometer facts, not a “seat of the pants” guess.

Eye opening information is what you get whenever you monitor delivered power! See what’s causing your drive-line problems, poor 0-60 times, or that disappointing off-turn acceleration. R&D projects uncover exciting and formerly hidden performance relationships when every change is evaluated via a new dyno curve. You will learn things you never even knew to ask questions about.

Factory direct technical phone support, before and after the sale, helps you get the most out of our rotary torque transducer technology. You speak directly to the company that designed, built, and sold you your hardware and software (no third-party “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!
