Land & Sea's DYNOmite Chassis Dynamometer Systems combine sophisticated data acquisition electronics with DYNO-MAX 2000 software for affordable, inertial + steady state horsepower testing.   "High speed power testing and road load simulation without ever leaving the garage. " Typical 500 Hp absorption chassis kit includes 12" medium inertia dual-roller assembly, removable roller shield, drive-up ramps, wheel chocks, vehicle tie-downs, casters, 13" water brake absorber (with over-drive), electronic torque transducer, DYNOmite data acquisition computer, Electronic Auto-Load Servo, DYNO-MAX 2000 software, inductive RPM pick-up, AC power supply, stainless braided hoses, engine temperature thermistor, and full-function data wiring harness. 750 or 1,200 Hp Pro chassis kits include tube steel frame with 24" or 44" diameter medium inertia twin rolls, bolt-on diamond plate decking, floor anchors, wheel chocks, vehicle tie-downs, 13" water brake absorber (with over-drive), electronic torque transducer, DYNOmite data acquisition computer, inductive RPM pick-up, DYNO-MAX 2000 "Pro," color printer, Windows XP equipped IBM laptop, computer stand, Electronic Auto Load Servo, Weather Station Kit, A/F Ratio module, 42" cooling fan, full function data acquisition wiring harness, engine temperature thermistor, stainless braided hoses with aircraft fittings.

DYNO-MAX 2000 [TM] software creates a full vehicle dashboard on your PC. Features include: real time trace graph display, adjustable limit-warnings, push button controls, user configurable analog and digital gauge ranges, color graphing, test report database, inertia compensation, "Smart Record [TM] " trigger points, adjustable data dampening, data import/export, semi-automatic zeroing, instant playback, voice alarms, etc. DYNOmite Data Acquisition Computer automatically displays and records true horsepower, torque, RPM, elapsed time, etc. at over 200 readings per second. It can even be set to automatically apply Standard, SAE, and DIN correction factors for air temperature, barometric pressure, and relative humidity.

More than acceleration Hp can be measured with DYNOmite absorption units because they include an actual strain gauge equipped torque transducer. Other companies' inertial only chassis "dynos" simply spin the vehicle's drive-line up to speed - against the roll's "flywheel resistance" (or unmeasured parasitic brake drag). Torque is only back calculated from the roller's inertia and acceleration. Such units can't maintain an RPM or MPH setting (vital for properly mapping engine management systems or emissions work)! It's similar to calculating Hp from your drag-strip ET.

Sustained Hp and top end can only be handled by absorption dynamometers (like the DYNOmite). Unlike "acceleration spurt" inertial testing, you can load the vehicle indefinitely. * The absorber allows running controlled RPM step and sweep Hp tests. Everything is done under computer control via the included "Electronic Auto-Load Servo. "

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 can simulate vehicle momentum, air drag, rolling friction, etc. Enter the vehicle's weight and drag data to let this software 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 or rear-wheel drive cars (and large bikes) can be tested on the appropriate model automotive chassis dyno units. Even narrow ATVs fit the 500 Hp dual-roller assembly.

Dynamically balanced and specially grooved rollers dramatically limit vibration and tire slip! Test most production vehicles (up to 140 MPH and 500 Hp) on our smallest automotive dual-roller assembly. Larger diameter twin roll units easily handle sustained higher speed testing at race car power levels. (Capacities 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, drive shaft vibration, brake chatter, bearing noises, brake shudder, exhaust rattles, etc. - without costly field testing.

Verify emissions under load using your existing, or our optional (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 emission compliance. Send your customers for state inspections with confidence.

Low profile, ramp loading allows installing the 12" dual-roller units above ground - even 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 test rides. Drive on, secure the vehicle, clamp on the tach lead (or use "Smart Ratio [TM] "), and test! When you're done, a test report is just a push button away.
