What is a Chassis Dyno?

Where an engine dyno measures power directly from the engine, a chassis dyno measures engine output or drivetrain output at the vehicle's drive wheels. In short, an AWD chassis dyno consists of a platform with four rollers, a braking or power absorption system, and software to calculate power output.

Why a Chassis Dyno?

The chassis dyno has the ability to measure power at the drive wheels—the “real world” performance of a vehicle. You can make tuning changes and test parts to find out the effects on power, as well as get the most out of performance-adders. A chassis dyno can also give you a good idea of how efficient your drivetrain is. In addition to these benefits, Karl Performance also has the capability to monitor air/fuel ratios, via an O2 sensor in the exhaust, and various other engine parameters.

While a pure engine dyno is beneficial, it does not give you to-the-wheel numbers like the chassis dyno will.

Determining and perfecting the true overall performance(horsepower and torque) of a vehicle's drivetrain is where the chassis dyno really shines.
