Absorbed Power​

Inertial bench vs. brake bench

Inertial measurement is highly repeatable, simple, and easy to control: you accelerate and you get the power curve. But it has a limitation: it doesn't let you control the load applied to the engine. You can't keep the engine or vehicle under load at constant speed; there must always be acceleration. For certain professional applications, a constant load is required, and that's what a brake dyno (also called an absorption dyno) is for.

Absorption Dynamometers

  Absorption dynos convert the energy delivered by the engine into heat. Inertial dynos, by contrast, convert it into rotational kinetic energy (which also ends up as heat when the bench's own brake stops the rotating mass at the end of the test).

The most common absorption dynos are electromagnetic eddy current and hydraulic. In both cases, the energy is dissipated as heat transferred to air or cooling water.

How power is measured

The measurement principle is one thing; how the electronics and software read that information is another. Sampling frequency, sensor precision, and signal processing all come into play. Each of these variables affects the final result, and the system design aims for the best balance between them.

The Design

What sets us apart

All data acquisition system manufacturers work with similar components: sensors, capture electronics, and software. The difference lies in how the sensors are chosen, how measurement is synchronized, and which algorithms transform that data into real values of acceleration, RPM, torque, and power. Our goal is to deliver high-end performance at an accessible price. ​

The components

The system consists of three parts:

1. The sensor, which detects rotation.
2. The electronic interface, which captures the signal and sends it to the computer.
3. The software, which processes the raw data and presents it in a clear, useful way.

The Support

24/7 AI support + human team

You get an AI assistant available 24 hours a day that knows the full manual and has access to a knowledge base of previous cases and solutions. It resolves most queries instantly, with no waiting or business hours.

When a case requires human intervention, it automatically escalates to our team via WhatsApp with the full conversation context already gathered, so you don't have to repeat anything. We get straight to the point: we guide you, send you the specific manual link you need, or solve the query on the spot.

When something goes wrong

If a problem comes up, we help you diagnose it. We'll ask questions, request photos or videos, and go step by step until we find the cause. We stay with you throughout the process until the equipment is running again.

Real Applications

Who is it for?

This kit works on engine test benches and chassis dyno benches with a brake dynamometer. Installation requires two things: mounting a rotation sensor with a magnet on a rotating part of the dyno (or on the roller for chassis dynos), and mounting a load cell on the brake to measure the applied force (torque). More details in the online manual​

There's no power limit imposed by the system: the same hardware and software work for a 10 HP bench or a 1000 HP one.

The Real Limits

The limits are defined by the dyno's power absorption capacity and maximum torque, together with the roller's inertial mass. ​

Combined Measurement

Toda medición del Forza es la combinación de dos componentes: la potencia absorbida por el dinamómetro, medida con la celda de carga, y la potencia entregada por el motor que se convirtió en energía cinética rotacional. Esta segunda parte no la mide la celda de carga, porque nunca llegó al freno: quedó en el camino acelerando las masas rotantes, y hay que medirla aparte.

That's why all our systems measure inertial power, which is combined with absorbed power to show total power. This calculation method allows measurements with the engine accelerating, without having to stabilize it at fixed RPM steps.

What can you measure?

The system can measure:

• Power
• Torque
• RPM
• Acceleration times
• Lambda sensor (wideband or narrowband)
• Pressure and auxiliary temperature sensors ​
• Friction losses (allows estimating crankshaft power on roller dynos, not just wheel power)

It also applies automatic weather correction through the SAE Correction Factor, delivering normalized values on every run.

The Forza has a control output that can drive the dyno through variable voltage. A dyno power controller with PWM or variable voltage input is required, usually supplied by the dyno manufacturer.

Typical uses:

• Engine benches with hydraulic dynos
• Engine benches with air-cooled or water-cooled eddy current dynos
• Roller benches with any type of dyno
• AWD roller benches with a single dyno
