A Dyno (aka “Dynamometer”) is an instrument used to measure the power output of an engine. It’s also used to evaluate changes to the maps during the development process when mapping an engine.

Without a DYNO, a remap is just guesswork!

It is a type of metrology. Which is the science of measurement.

With a competent & highly experienced operator, a good dyno allows for the scientific evaluation of systematic and subsequent changes to an ECU (engine control unit). The dyno gives a vast amount of managed data back to the operator whom then uses this information to make calculated changes to the maps.

This is what professional remap development involves.

A controlled process with an accurate machine to get the best results while keeping the engine within safe operating parameters.

There are many different brands and types of engine controller. Each requires a specific approach and interface. Lookout for future articles on this topic

Engine Dynos

These are dynos that directly connect to the engine’s crankshaft to measure engine power without transmission or some parasitic losses (alternators, PAS pump etc). They are used in OEM development to create the initial calibration on new powertrain units.

 

This is only practical for final-mapping where the following systems are what will be mounted on the vehicle:

  • intake system (air box and associated air charge piping)
  • intercooler system
  • Exhaust System
  • Cooling system
  • Fuel system
  • Electrical power distribution system and earth bond resistance

This is why it is a pointless expense in freelance mapping since these systems will be totally different on an engine dyno compared to the equipment that will be used in the chassis of the car

Chassis Dynos

This is where the whole car is attached to the machine to measure it
There are two main types: Hub Dynos and Roller-Dynos

Types of Chassis Dyno
Roller dynos are an old fashioned system using metal drums mounted on bearings, where the whole car is strapped to the machine ontop of these drums. (Learn more about these in an upcoming video!)

Hub dynos represent a massive advancement in dyno technology as the car is directly bolted to the machine, this eliminates many ‘variables’ and the hidden cost of excessive tyre-wear during calibration. It also eliminates the risk of cars flying off the machine like you often see on youtube videos of rollers.

Dynapack is the most advanced hub dyno on the market, second to none!

Yes you can!

These are in RDT’s experience the best chassis dyno system available on the market. They’re also the most reliable and repeatable system out there. When you watch our video (release date TBC) giving out all the dyno secrets you’ll discover just how¬† different and how much more control these have.

If you want to learn more about dynos, how they work and what makes a good dyno then checkout our soon to be released video explaining exactly how they work. (link to be added)

Putting your car on a Hub-dyno is a very safe and rewarding process.

You’ll be safe in the knowledge that your race car or daily pride & joy is bolted directly to the machine.
There is ZERO wheel spin and no wear to the tyres (which is a hidden cost).
