1,200 to 2,500+ Hp** Pro chassis kits include a FWD/RWD (optional AWD upgrade shown below) tube steel frame with 24", 30", 44", or 60" diameter medium inertia rolls, bolt-on diamond plate decking, floor anchors, wheel chocks, vehicle tie downs, water or eddy current absorber(s) with step-up drive, electronic torque transducer, DYNOmite 28-channel data acquisition computer, inductive RPM pick-up, DYNO-MAX 2000 “Pro” software, printer, Windows XP® equipped Dell™ laptop, mobile computer stand, Electronic Auto-Load Control, Weather Station Kit, A/F Ratio module, 42" high volume cooling fan, hoses, engine temperature thermistor, and full-function data harness.

DYNO-MAX 2000™ “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 DYNOmite absorption units, because they utilize an actual strain gauge equipped torque transducer. Measuring power under a controlled RPM load is vital for proper mapping of engine management systems and guess-free emissions work. Avoid “dynos” that simply spin the vehicle’s tires up against a roll's inertia (“flywheel resistance”) without any option to accurately control and measure absorption load. Rather than measuring torque, they derive it from the acceleration (similar to extracting Hp from drag-strip data). Such units can’t maintain a MPH or RPM setting, while displaying true Hp and torque – like a DYNOmite can!

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 allow the software to monitor MPH vs. applied Hp, as it adjusts the dyno’s road load accordingly. To the drive-line and operator, the feel is like actually driving along.

Front, Rear, or All Wheel Drive cars and trucks can be tested on the appropriate model automotive chassis dyno. Many allow front/rear torque bias monitoring and bidirectional mounting. Even large bikes and ATVs fit the 700 Hp dual-roller assembly. We can also convert many other manufacturer’s older, single axle, chassis dynamometers to AWD, with full Electronic Axle Synchronization, at a fraction of the cost of a new installation!

Dynamically balanced and machine Traction Grooved rollers dramatically limit vibration and tire slip! Test most production vehicles (up to 150 MPH and 700 Hp) on our smallest automotive dual-roller assembly. Larger diameter roll systems easily handle sustained higher speed testing at race car power levels. (**Capacities are approximate, as they are primarily tire safety and traction limited – higher torque requires tie downs.)

Fix drive-line problems that never show up in the garage, like shifting issues, driveshaft vibration, brake squeal, bearing noises, brake shudder, exhaust rattles, etc. - without costly field testing.

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 your customers for state inspections with confidence.

Low profile, ramp loading allows installing the 12" dual-roller units above ground - or in the driveway. Casters let you roll it to a corner when not in use (just raise the anti-vibration leveling pads). No dedicated test bay, or digging up floors, required.

Rapid on-off set-up makes it practical to test most vehicles, without time-consuming road excursions. Just drive on, secure the vehicle, clamp on a tach lead (or use “Smart Ratio™”) and test - a full report prints out automatically!
