Frequently Asked Questions

Welcome to the FAQ's page. Here we will try and answer some common turbocharger related questions as simply as possible. If you have any further questions please feel free to contact us via our contact page.
  1. How does a turbocharger work?

    To put it simply, the exhaust blows through a turbine, which in turn drives another turbine which pushes air into the intake manifold. This increases the air pressure in the 'explosion chamber', causing the fuel to burn far more efficiently than a non-turbocharged engine, thereby creating more horsepower. As it is more efficient you can pump more fuel into the engine as well, increasing the force of the explosion. On top of this the air is also heated up in the compression stage, also adding to the burn quality of the fuel.

  2. How many revolutions per minute does a turbocharger spin at?

    This depends on how much 'boost' the turbocharger is currently pushing, but some or the smaller turbochargers can spin at up to 200 000 revolutions per minute.

  3. How often should I service my turbocharger?

    You should service your tubo every 100 000 kilometers. A turbocharger runs at very high temepatures and revolutions, and requires quality oil to run on. The only way to ensure you get maximum life out of your turbocharger is to service it regularly.

  4. What is the main cause of turbocharger failure?

    Simply put, the engine. A well serviced, reputable brand of turbocharger will not just 'give up'. If your engine is in good condition and both your engine and turbocharger are serviced regularly, the turbocharger should last the lifetime of the engine. Please refer to our 'Articles' page for more information on turbocharger failures and how to avoid them.

  5. Do modern vehicles need to be idled before switching off?

    YES, YES, YES. A turbocharger is a free spinning item, when the engine is turned off the turbocharger continues spinning for up to 3 minutes. As the turbocharger is lubricated with the engines oil the turbocharger is spinning without any lubrication after the engine is turned off. The turbocharger is mounted directly onto the exhaust manifold, heat soak occurs after the engine is turned off causing a breakdown of the oil. It is thus essential to idle the vehicle to allow the turbocharger to slow down and cool off.
