A dynamometer is a device that measures the power, torque, and force of your vehicle. A dyno tune is run on this device, which is also known as a dyno. It can give your mechanic valuable information about your vehicle’s engine. That information helps them diagnose problems, and get your car in perfect working order. In order to get that information from your vehicle, a dyno tuning needs to be performed.

What Is A Dyno Tune?

A dyno tune is a way for your car technician to determine how much power and torque your engine is producing. This works by making the dyno mimic certain driving conditions so that the power of the engine can be calculated.

That data about the engine will then be compared to the manufacturer’s specifications. This lets your technician know if something isn’t right, so they can advise you on whether or not you need a tune-up.

If you feel that your car isn’t as powerful as it should be, a dyno tuning can help you confirm your suspicions, or let you know if something else is the problem. While there’s no set “time” that you should get a tune, it doesn’t hurt to do it every few years, especially if you have an older vehicle.

What Does A Dyno Tune Tell You About Your Car?

A 4WD dyno tuning can provide you and your technician with a lot of valuable information. These tests aren’t just for petrol vehicles, you can also tune a diesel engine. Here are a few key examples of what you can learn from a 4WD dyno tuning:

1. Whether Or Not Your Engine Is Running Properly

A tune can provide you with information regarding your:

  • Intake manifold
  • Ignition timing
  • Primary tube diameter and length for the headers
  • Carburetor spacers
  • Cam grind
  • Carburetor size and jetting

This information can help diagnose problems with your car, and let you know what general shape it’s in. Whether you tune your 4WD or 4×4, you’re sure to get some valuable information.

2. The Temperature Of Your Exhaust Gas

Knowing the temperature of your exhaust gas can be crucial when it comes to keeping your carburetor and engine in good shape. It can help diagnose problems early and save you from major engine repairs later on.

3. To Make Sure A New Engine Is Running Properly

Performing a dyno tune on a new engine helps ensure that it’s running properly before you head out onto the road. While problems with new engines aren’t common, it never hurts to check.

Running a test also provides you with a written record of your engine’s performance, which is helpful for you and future owners of the car.

What Are The Different Types Of Dynamometers?

There are three main types of dynos in use today. They are inertia dynos, water-brake dynos, and electric dynos. Let’s go over what each of them does in detail.


Inertia Dyno

An inertia dyno uses an accelerometer and computer software to measure the acceleration rate of the dyno drum. This only works while the car is accelerating. Because of this, the car must be placed on the dyno with the drive wheels sitting on the rollers and then be placed in gear and accelerated with the throttle wide-open.


Water-Brake Dyno

The water-brake dyno uses a constant speed brake attached to a rotor with a rotating element and a still element. The car sits on the dyno while water or hydraulic fluid applies the braking force. A strain gauge is then used to measure torque reaction and calculate the horsepower output.


Electric Dyno

Electric dynos are used during bench tests to determine the horsepower and other characteristics of the engine. It works like a generator and is connected to a motor when the motor is ready to be tested. DC generators can be used as electric dynos.

What is 4x4 dyno tuning?

If your test reveals problems with your car or its engine, your mechanic may recommend a dyno tuning.

A 4×4 dyno tuning is a process that involves making adjustments to your ignition, fuel, and air supply to maximise your horsepower and torque without ruining your air-to-fuel ratio. This tune-up can lead to a lot of benefits for you and your vehicle, including:

  • Increasing your fuel economy. You may find that your fuel lasts longer after a tune-up.
  • Lowering your engine temperature. A tune-up can address problems that cause your engine to run hotter than it’s meant to.
  • Increasing your performance. Your horsepower and torque can both be increased by having a tune-up performed.

A test can help you identify problems with your power or torque, as well as letting you know if it’s time for a dyno tuning. If you’re ready to maximise your car’s power, you can book a 4×4 dyno tuning in Perth today.

How Does Dyno Tuning Actually Work?

Dyno tuning is the process of making adjustments to your vehicle's ignition, fuel supply, or air supply. These changes allow your vehicle to reach higher levels of horsepower and torque while maintaining a good fuel to air ratio. During a dyno tune, the technician visually examines your car and asks you questions. They then examine your distributor for flaws and place the car on the dynamometer. This allows the vehicle to be tested under various driving conditions to test its performance. The vehicle will be tested again after the adjustments are made.

How Much Performance Can You Get From a Dyno Tuning?

On average, a dyno tuning will increase your horsepower by 10% to 15%. This is assuming that the vehicle was operating at factory standard before the tune. More horsepower can be achieved by upgrading other parts of the vehicle, such as the exhaust and turbo. In some cases, you could see up to a 25% increase in your horsepower. This in turn increases your speed, fuel efficiency, and torque. Dyno tuning is a great move for those wishing to get more out of their factory-stock vehicle. Just make sure your upgrade is performed by a qualified technician.

How Long Does a Dyno Tune Take?

How long a dyno tune takes depends on the condition of your vehicle. On average the process is between two and four hours. To ensure that your tune goes quickly and smoothly, consider:

  • Checking for leaks in your vacuum, intake, and exhaust.
  • Ensuring that your fuel system is working properly.
  • Changing your spark plugs and oil.
  • Inspecting your tires for damage.

Ensuring that your car is in good working order prior to your dyno tune will speed up the process.

What Does a Dyno Tune Do?

Dyno tuning is the process of testing your vehicle to determine its horsepower, air to fuel ratio, and torque. Once these are known, changes can be made to ensure that your car is operating at peak performance. The two types of dyno tuning are engine and chassis. An engine dyno measures the engine numbers, while a chassis dyno measures the full power generated by the wheels.
