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.

Racer Class absorber-type limitations:

Absorber on engine-stand dyno frame. Bellhousing-mount absobers (single-stator water brakes) are suitable for casual engine testing. They offer the lowest cost for entry-level testing – even for many mid-power motors. However, if your primary usage will be higher-volume or more-serious engine bulding, consider upgrading to an Engine-Builder Class system, with their more sophisticated docking-station/rolling-cart configuration.



Absorber on engine-stand dyno frame. Bellhousing-mount Siammese-rotor absobers (dual-stator water brakes) are suitable for casual higher-power engine testing. They offer the lowest cost for entry-level testing – even for many high-power motors. However, if your primary usage will be higher-volume or more-serious engine bulding, consider upgrading to an Engine-Builder Class system, with their more sophisticated docking-station/rolling-cart configuration.

• Absorber type: water brake

• Peak power limits:* 850 Hp, or 1,900 Hp

• Peak torque limits:* 900 ft·lb, or 1,800 ft·lb

Engine-Builder Class absorber-type limitations:

Absorber on docking-station dyno frame. Docking-station frame-mount absobers (single-stator water brake) are ideal for serious race-engine testing. They offer the best price/performance ratio for proffesional dynamometer testing – especialy for higher-volume engine bulders and busy race teams. Note: Research labs and OEM's should consider upgrading to an R&D Class system, with their very-low inertia and super quick response, AC or liquid-cooled eddy absobers – in either a docking-station/rolling-cart or trunnion mounted absober configuration.

Absorber on docking-station dyno frame. Pro docking-station frame-mount absobers (dual-stator water brake or eddy-current) are ideal for serious race-engine testing. They offer the best price/performance ratio for proffesional, high-torque or high-power, dynamometer testing – especialy for higher-volume engine bulders and busy race teams. The dual-stator water brake versions boast lower inertia and higher RPM limits, while air-cooled eddy-current absorbers are optimum for very-high torque applications. Note: Research labs and OEM's should consider upgrading to an R&D Class system, with their very-low inertia and super quick response, AC or liquid-cooled eddy absobers – in either a docking-station/rolling-cart or trunnion mounted absober configuration.

Wall console is detachable from mobile engine stand (above) for remote operation from your control room.

Mobile Test Stand Dynos (below and far right) include: tube-steel engine frame (with quick-adjust mounts, heavy-duty locking casters, and engine leveling jack), 13" toroidal-flow water-brake absorber, load control, DYNOmite data-acquisition computer, full-bridge electronic torque arm transducer, wall (or stand) mounted console, bell-housing adapter plate, input shaft, calibration arm, stainless-braided hoses, engine-temperature thermistor, and full-function data wiring harness. (Several other modular options, like our cooling tower and full docking station or reaction cradle mount configuration upgrades, may be added at any time.)

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.)

   → See General Specifications or Models and Prices pages.

Optional 3,000 Hp toroidal-flow absorber responds twice as quickly as ordinary vane-type brakes. 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 acquisitio electronic circuit-board set. 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.

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.

Sample water-brake absorber plumbing.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.)
