AEM’s Dyno-Shaft Sportsman on-vehicle dynamometer system is literally a dyno on your car. It is as accurate as the most respected dynamometers in the industry. It provides real, accurate Horsepower and Torque numbers that are produced by measuring a vehicle’s Torque and RPM at the driveline, while you drive! The Dyno-Shaft Sportsman Series is designed for competitive amateur racers and serious performance enthusiasts whose applications can utilize a cast iron slip yoke. For higher stress applications, the Dyno-Shaft Pro Series kit features a CNC-machined Chrome Moly slip yoke.

Eliminate Guesswork – Know for sure if slower times are due to a loss of power, vehicle set up or driver error.

Engine tuning – Stop trying to approximate real world test conditions and start testing in the real world! Finally you can test with actual intake air conditions, actual vehicle loading and the hundred other things that make a real vehicle behave very different than it does when on a dyno.

Chassis Set Up – Know when the tires will break loose. Ideal for optimizing drag launches and determining the longitudinal forces your tires can handle in road racing.

Torque Converter and Clutch development – Finally know what your Torque converter or clutch is doing while you are making a pass!

Dyno It All – The Dyno-Shaft accurately reads in all conditions including steady state, uphill or downhill, even while coasting down!

HOW IT WORKS
AEM uses a set of laboratory-grade strain gauges inside of a supplied calibrated slip yoke to measure Torque at the driveshaft. Essentially, the Dyno-Shaft slip yoke assembly becomes the sensor for measuring driveshaft Torque. This is combined with a driveshaft speed sensor to precisely measure the rotational speed of the yoke to determine RPM. The combination of real Torque and RPM readings allow the Dyno-Shaft to output Torque and Horsepower numbers as accurately as any dynamometer but in a more useful setting, and eliminates all of the inaccuracies associated with accelerometer or GPS based systems.

The data broadcast device (Controller) for the Dyno-Shaft yoke is non-contact, does not have slip rings, does not require batteries and is maintenance free. This Controller installs over the transmission tail shaft housing and allows information from the Dyno-Shaft to be transmitted via AEMnet (AEM’s CAN bus communications network) to a data logger, AEM or other programmable engine management system or custom dash.
