The only dyno line that expands with your needs. Start today with one of our low-cost bellhousing-mount water-brake models. Later add a docking station, expand to increase data channels, upgrade software, etc. – without wasting your original investment. Excluding absorber-type (see below) most of your important feature decisions may be revisited, even years later. We manufacturer all major components in house – saving you third-party markups of competitors.
One configuration does not suit all! The above paragraph notwithstanding, one unique specification will lock you in: absorber type. It limits the usable response/speed/power (class) of any engine dyno.
• Only doing break-in, or leak testing? Then a simple SAE-bellhousing mount water-brake Rebuilder Class absorber may be okay.
• Tuning 500+ Hp drag/street/pulling engines? Get serious with docking-station Performance Class absorber systems.
• Developing industrial engines, or performing diesel research work? Demand eddy-current or AC Industrial Class absorbers.
Call to let us help you do your homework on this absorber-type topic, and others, or continue reviewing below:

Typical diesel dynos include: 19" heavy-duty toroidal water-brake or large eddy-current absorber, S-beam electronic torque transducer, high-flow manual (or optional electronic) engine load control, DYNOmite data-acquisition computer, rigid-frame engine test stand, wall (or stand) mounted control console, absorber to engine-block mounting adapter, heavy-duty input shaft, calibration arm, stainless-braided hoses, and full-function data wiring harness. See Specifications or Models and Prices pages.
Develop more powerful engines by pinpointing exact RPM locations of horsepower loss or gain. Evaluate components, tuning changes, engine durability, etc.
DYNOmite data-acquisition computer displays and records true unlimited Hp, torque, RPM, elapsed time, etc. at up to 1,000 readings per second (per channel). It will even automatically apply inertia compensation and SAE correction factors for air temperature, barometric pressure, and relative humidity – a full report prints out automatically! Electronic load and throttle control options – just push buttons to select the test RPM, or set a sweep rate and the DYNOmite’s own advanced PID algorithm runs the whole show – all hands free. Advanced features include: Smart Record™, data dampening, spike filtering, playback data averaging, atmospheric correction, auto-zeroing, instant playback, and integral rev-limiter.
Integrate your Windows PC using DYNO-MAX, together with our appropriate automated electronic load and throttle control hardware options, for keyboard dyno control. Without special programming you can easily execute many complex break-in or endurance simulations and custom engine test cycles.
DYNO-MAX™ software option creates a full engine dynamometer lab on your Windows PC. Features include: real-time trace graph display, adjustable voice/color limit warnings, pushbutton controls, plus user configurable analog and digital gauge ranges. Publication-quality color graphs and detailed reports are available for printing or even importing into other programs. With appropriate automated electronic loading and throttle control hardware options, operators can easily execute complex race simulations and engine test cycles.
Instant test results display on either your DYNO-MAX-equipped PC or the optional portable DYNOmite LCD. Either configuration can output reports to your compatible printer (an optional ASCII thermal printer is available for portable operation).
Engine test stand options include our standalone mobile frame type with its SAE bell-housing torque tube-mounted absorber – or the docking cart and station design (shown above). Both configurations feature a rugged tubular steel frame (with heavy-duty locking casters for easy in-shop mobility). Mounting options include using either heavy-duty fixed engine plates or adjustable leveling jack screws.
Block mounting adapters are available with torque tubes that couple the absorber to many popular Cummins, Caterpillar, etc. diesel engines. Their unique sealed-bearing design transmits no torque back to your engine stand (or shipping pallet). Bell-housing plates can be field adapted to other applications.
Heavy-duty solid stainless shafts are used in both our single-rotor and our Siamese-rotor 19" or 26" toroidal flow diesel absorbers. All the shafts and U-joints are heat treated – for longer life under the extreme torque loads of diesel engine testing cycles.
MAX – How Water Brakes Work - Animated look at how water-brake absorbers create load (MAX narrated).
Precision torque transducers all use temperature-compensated full-bridge strain gauges. Environmentally sealed industrial S-beams, load cells, or torque tubes measure the precise shaft torque, allowing the data-acquisition system to accurately calculate repeatable real-time horsepower. Pushbutton, semi-automatic zero-offset calibration is a standard feature. The software even provides support for bi-directional torque readings – for testing counter-rotation engines.
4,000 foot-pound* and 2,000 Hp* capacity using our 19" heavy-duty dual-stator water-brake absorber (with Siamese rotor). Its advanced toroidal-flow design loads larger engines and delivers much better controllability than any older vane designs. (Other hydraulic, water, AC, and eddy-current absorber combinations are available to test engines from 1 to over 10,000 Hp.)
“Pro” console upgrade includes a genuine Intel®-equipped Dell™ PC and a 17" high-resolution LCD monitor. It is optimized for DYNO-MAX’s real-time color graphics. (See specifications table for a longer list of features.)
Reduce field service problems by getting it right the very first time, while improving customer satisfaction. Uncovering turbo or injection system malfunction is no longer trial and error.
Low-cost and rapid installation are just two benefits of the standalone version’s unique design. For many applications this configuration allows testing right on the engine’s shipping crate. An expensive dyno cell is often not even required.
Easy test set-ups by mechanics and technicians with no dyno experience. Get quick horsepower plots of the entire torque vs. RPM curve. No prior experience with computers is needed. It can take less than an hour to install, test, and output report data with the DYNOmite. Just mount the absorber and torque-tube adapter plate assembly onto your engine’s bell-housing (or couple a rolling cart-mounted engine to its docking station), hook up the wiring and hoses, and begin testing.
Automated load control is available with the optional electronic auto-load servo (high or ultra-flow) control valve. It replaces the standard manual-load control unit. Just push the buttons to select the operating RPM, or set a sweep rate and allow the DYNOmite’s advanced PID algorithms to run the whole test. The computer logs all data automatically. (Simultaneous electronic throttle control, via DYNO-MAX, is also an available option.)
Advanced options including: thermostatically controlled cooling towers, fuel-flow and airflow turbines, blowby sensors, weather station (for automatic atmospheric data), EGT (exhaust-gas temperature) thermocouple kits, pressure transducers, fully digitally integrated five-gas exhaust analyzers, direct-mount smoke-opacity meters, temperature thermistors, auto-load and electronic throttle control, and more.
Live-person technical phone support provides a significant advantage over other companies’ endlessly frustrating voice-mail tag. In addition, our standard hardware phone and e-mail support, plus access to the special DYNOmite owners 24/7 web support area, are all FREE!
*Approximate; continuous capacities depend on selected absorber and test speed. Air-cooled absorber loads are rotor temperature dependent. Water brake power capacities are RPM dependent and assume a minimum water supply of 1 gpm @ 30 to 60 psi for every 20 continuous Hp.
