2,000+ or 3,000+ Hp** Pro AWD axle-hub systems include four heavy-duty rolling modules with eddy-current controllers and high-speed (low-inertia) air-cooled absorbers, automatic camber compensation, thermostatically-controlled fans, electronic AWD-axle synchronization, four dual torque transducers, swivel casters, alloy quick-change axle-flange adapters, DYNOmite-Pro data-acquisition computers, axle and engine (inductive clamp) RPM pick-ups, Auto-Load Control, 28-channel data harnesses, temperature thermistor, DYNO-MAX “Pro” software, Windows-7 equipped Dell laptop, computer stand, Air/Fuel Ratio Module (with pump), Weather-Station Kit, 42" cooling fan, color printer, banner, accessories package, and manual. Available with Active-Synch™ (axle-synchronization and motoring option).

Reads TRUE axle-hub Hp using precision full-bridge temperature-compensated torque transducers - and includes compensation for driveline inertia during transient testing. Only axle-hub or engine dynamometers isolate Hp from the inconsistencies of tire-to-roll traction. They provide the repeatable data serious tuners and engineers need to compare against baseline tests. However, unlike engine dynamometers, axle-hub testing requires no engine removal from the vehicle.

DYNO-MAX™ “Pro” Software creates a full vehicle dashboard on your PC. Features include: real-time trace graph display, adjustable limit warnings, pushbutton controls, user configurable analog and digital gauge ranges, color graphing, test report database, instant playback, inertia compensation, “Smart Record™” trigger points, adjustable data dampening, full data import/export, semi-automatic zeroing, voice alarms, wireless Pocket DYNO-MAX™ interface, drag strip Christmas tree console, etc. (Click for full list of features.)

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 SAE correction factors for air temperature, barometric pressure, and relative humidity.

More than acceleration Hp can be measured with the DYNOmite axle-hub modules, they have the continuous absorption capacity that serious tuners need. Measuring power under temperature stabilized (longer-term) controlled steady-state RPM loading is vital for proper mapping of engine management systems and guess-free emissions work.

1,600+ Hp** 2WD capacity with our unique planetary-drive axle-hub absorbers (shown at left). These compact high-speed units are based on our fast response 13" toroidal flow water-brake absorbers. They bring engine dyno cell load capacities and testing capabilities   right to the race car!  (mounts directly onto most 2WD  model vehicles with the included (or other optional) axle-flange adapters.

Sustained Hp and top end require an absorption dynamometer (i.e. a DYNOmite system). Unlike “acceleration spurt” inertial testing, these can load a vehicle indefinitely.* The absorber allows running controlled RPM step or sweep Hp tests. Everything is under computer control via the included Electronic Auto Load.

Simulate driving conditions on your chassis dyno by letting DYNO-MAX and your PC take control. DYNO-MAX features a “Road Load Simulation” mode that simulates vehicle momentum, air drag, rolling friction, etc. Enter the vehicle’s weight and drag data and then allow the software to monitor MPH vs. applied Hp, as it adjusts the dyno’s road load accordingly. To the car’s driveline and operator, the feel is like actually driving.

Verify emissions under load using your existing, or our optional (digitally integrated) DYNOmite 5-gas, exhaust analyzer. Proper emission testing procedures require repeatable absorber load control, impossible on simple inertia dynos. No more trying to use unloaded idle data to verify that repaired vehicles are in emissions compliance. Send customers for state inspections with confidence.

Traction-Controlled Front, Rear, or All Wheel Drive cars and trucks can be tested with the appropriate model DYNOmite axle-hub AWD axle-hub dyno or a 2WD model using our Active-Synch™ axle-synchronization modules. All AWD models allow front/rear torque bias monitoring and our high-end AC versions even allow sophisticated traction control testing. We can also update many other manufacturer’s single-axle chassis dynamometers, with our Active-Synch™ axle-synchronization modules, to allow testing of traction controlled vehicles. These modules feature 20 Hp motoring drive units and micro-second response AC controllers that provide precision matching of the un-powered axles (on traction controlled ABS equipped vehicles) during 2WD dynamometer testing.

Quick-change axle-flange adapters and caster equipped modules are easy to set up for a test, making it practical to skip those old time-consuming road trips. Just remove the tires, couple the adapters, hook up the tach (or use “Smart Ratio™”) and test – a full report prints out automatically! When you are done, the same wheels allow you to just roll the modules into a corner of your shop. No dedicated test bay, or digging up floors, is required.

Dynamically balanced flywheels, concentric axle-flange drive interface, and automatic camber compensation dramatically limit vibration ! Test most production vehicles up to 200 MPH.

Fix driveline problems that might never show up in the garage, like shifting issues, driveshaft vibration, brake squeal, bearing noises, brake shudder, exhaust rattles, etc. - without costly field testing. Lack of tire noise or belt drives allows you to more easily hear what is going on, even at high speeds.

Specialty axle-hub (PTO) dynos are available, as custom systems, for testing ATVs, snowmobiles, tractors, and other recreational or industrial vehicles. As you can see on these pages, we manufacture more types of dynos than any other company in the world. Are you looking for what you think is a unique dynamometer system? If so, give us a call,. maybe we can help you!

**Approximate; continuous capacities depend on selected absorber and test speed. Air-cooled absorber loads are rotor temperature dependant. Water brake power capacities are RPM dependent and assume a minimum water supply of 1 gpm @ 30 psi for every 20 continuous Hp. Call Land & Sea, Inc. at (603) 226-3966 for the approximate capacity of any specific test configuration.
