The only dyno line that expands with your needs. Start today with one of our low-cost stand-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 block-mount water-brake Racer Class absorber may be okay.
• Tuning 500+ Hp drag/street/rally engines? Get serious with docking-station Engine-Builder Class absorber systems.
• Developing high-speed hyper cars, or performing research work? Demand eddy-current or AC R&D Class absorbers.
Call to let us help you do your homework on this absorber-type topic, and others, or continue reviewing below:

Test over 800 Hp* capacity with our standard 13" toroidal-flow water-brake absorber, or 2,000+ with Siamese-rotor version. Loads most high performance engines at any throttle setting or RPM you will need to test at – indefinitely! (Requires minimum of 5 gpm @ 30 to 60 psi for every 100 continuous Hp. Many other water brake, AC, or eddy-current absorber combinations are available to test from 1 to over 10,000 Hp.)
MAX – How Water Brakes Work - Animated look at how water-brake absorbers create load (MAX narrated).
Heat-treated input shaft couples the mobile stand’s absorber to your engine’s 1-3/8" x 10 splined clutch disk (or optional heavy-duty dampened engine drive plate). Docking station versions use a telescoping driveshaft.
Absorber to bell-housing adapter plate fits popular GM and Ford bell-housing patterns to the mobile engine stand. Its unique design transmits no torque back through the frame. Can be field adapted to other applications. Docking station versions feature a racecar-like engine plate.
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.
Patented torque arm technology features environmentally sealed strain-gauge-equipped torque transducer (temperature compensated) which measures true shaft torque and Hp. Pushbutton, semi-automatic zero-offset calibration is standard.
Advanced features include: Smart Record™, data dampening, spike filtering, playback data averaging, atmospheric correction, auto-zeroing, instant playback, and integral rev-limiter.
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.
Develop more powerful engines by pinpointing exact RPM locations of horsepower loss or gain. Evaluate components, tuning changes, engine durability, etc.
Know what works versus what should stay on the shelf. For the first time you can map a fuel-injection or spark-curve map without endless test track time. Perform standardized break-in, endurance tests, or run complex engine simulations from idle to full throttle – without any tedious programming.
Increase profits selling dyno services and improve customer satisfaction by diagnosing tough problems quickly. Uncovering marginal electrical and fuel system malfunctions or tweaking the correct settings is no longer trial and error. The value of dyno testing is well accepted and significant horsepower gains are common during tuning sessions, so customers willingly pay for dynoing.

Simplified installation is just one benefit of the mobile engine-stand’s design. With a few options, you can even roll your unit outside for testing – no expensive dyno cell or ventilation system required. However, as your business expands, you are ready to step up to a full-blown docking station test cell (above) and multiple engine carts – without squandering your original investment.
Easy test set-ups by mechanics and machinists with no dyno experience. Get quick horsepower plots of the engine’s 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 fasten the mobile stand’s absorber/adapter plate assembly to your engine’s clutch bell housing and bolt everything onto the stand’s adjustable mounts (or drop an engine onto a docking station cart and roll it into the cell), hook up the wiring and hoses, and test.
Automated load control using an optional electronic auto-load servo (high or ultra-flow) kit to replace the standard manual-load control. You just push buttons to set a test RPM or sweep rate and the DYNOmite’s advanced PID algorithms run the whole test. The dynamometer computer logs all the data automatically, so you do not have to run the engine to death just getting a simple test curve. You can even add an electronic throttle control to further automate many of DYNO-MAX “Pro’s” built-in tests or to maximize the capabilities of any simulations that you create. (Electronic auto-load control is standard on all our “Pro” water-brake, eddy-current, or AC-absorber dynamometer systems.)
Affordable upgrades including: spare rolling engine stands (or docking carts), cushioned drive plates (or telescoping driveshafts), sprint-car engine adapters, thermostatically controlled cooling tower, on-board fuel systems and starters, stainless-steel engine-stand drip tray, fuel-flow and airflow turbines, weather station, EGT (exhaust-gas temperature) thermocouple kits, AFR (air/fuel ratio) monitors, air and liquid pressure transducers, RTDs, thermistors, knock sensors, integrated five-gas exhaust analyzers, precision crankshaft-degree position encoders, high-speed cylinder-pressure mapping systems, and both servo-load and throttle-control options.

*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.
