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.

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 their roll�s inertia (�flywheel resistance�) without having any ability to simultaneously control and measure absorption load. Rather than measuring the torque, they derive it from the acceleration (similar to extracting horsepower from drag-strip data). Such units can not maintain a MPH or RPM setting, while also displaying true torque and Hp � like a DYNOmite can!

Click to enlarge 24" chassis dynamometer.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.

Click to enlarge 44" AWD chassis dynamometer.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!

Click to Services page for magnified view of grooves.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.)

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.

Click to enlarge 24" chassis dynamometer.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 skip those old time-consuming road trips. Just drive it on, strap it down, hook up the tach (or use �Smart Ratio��) and test � a full report prints out automatically!
