Standard Kart kits include: structural steel frame with 4-½"diameter medium inertia dual-roller assembly, vibration pads, front lift-on wheel stand, vehicle tie downs, 9” toroidal flow water brake absorber, electronic torque arm transducer, Auto-Load Servo, DYNOmite handheld data-acquisition computer, inductive RPM pick-up, AC power supply/recharger, stainless braided hoses, and data wiring harness. See Specifications or Models and Prices pages.

Features include: real-time trace graph display, EGT bar graph, inertia compensation, adjustable limit warnings, pushbutton controls, and user configurable analog and digital gauge ranges. With the optional electronic auto-load control (or electronic throttle) you can easily execute complex race track simulations, engine tests, or break-in cycles. Just push buttons to set any test RPM, or pick a sweep rate and let the DYNOmite's advanced PID algorithms run the whole show. (Click for full list of features.)

DYNOmite data-acquisition computer automatically displays and records true Hp, torque, RPM, elapsed time, etc. (at up to 1,000 readings per second) while automatically applying SAE correction factors for air temperature, barometric pressure, and relative humidity. Keypad model DYNOmites display results on their LCDs, and can print to an optional portable ASCII parallel printer. It even doubles as a racing data recorder.

Junior Dragster with 7” DYNOmite Kart Kit, ready to test.More than acceleration Hp* can be measured because the DYNOmite supports  an actual absorber and torque arm. Avoid “dynos” that simply spin the tires up against a roll’s inertia (“flywheel resistance”) without any option to both accurately control and measure an absorption load. Rather than actually measuring torque, they estimate it from the acceleration (similar to approximating Hp from drag-strip MPH). Such units can’t maintain a MPH or RPM setting, while displaying true Hp and torque!

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 “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 driveline and operator, the “feel” is like actually driving along. Kart Chassis Roller Assembly which allows for inertial acceleration testing (even without the 9” absorber), or steady-state testing when it is installed as shown.

Test small motorcycles and scooters or even narrow ATV’s by removing the bolt-on roller shield. 

Dynamically balanced and “traction grooved” rollers limit vibration and tire slippage. Unlike ineffective diamond knurling or roll coatings, our exclusive machined in grooves provide real traction and don't wear out. The extra traction means you don't need to use excessive (and power robbing) strap-down forces to test.

Fix driveline problems that never show up in the garage. Shifting problems, driveshaft vibration, brake chatter, bearing noises, brake shudder, exhaust rattles, etc. show up without costly field testing. 

Portable design means you can take it right to the track. No dedicated test bay or digging up of floors is required! 

Rapid on-off set-up makes it practical to test most vehicles, without requiring hard to arrange track time. Set-up the rolls, secure the vehicle, clamp on the tach lead, and test! When you’re done, a test report is just a pushbutton away.

*Approximate; limited primarily by tire safety and traction - higher torque transfer requires tie downs. Continuous capacities depend on selected absorber and test speed. Air-cooled absorber loads are rotor temperature dependent. Water brake power capacities are RPM dependent and assume a minimum water supply of 1 gpm @ 30 to 60 psi for every 20 continuous Hp. Call Land & Sea, Inc. at (603) 226-3966 for the approximate capacity of any specific test configuration.
