DIESEL TURBO SYSTEMS

Modern 4WDs powered by diesel engines are mostly suited to turbo charging.

Huge increases in torque (pulling power) and engine output make fitment of an aftermarket turbo system ideal for 4WD owners that:

  • Tow Caravans
  • Tow Horse Floats
  • Tow Car Trailers
  • Tow large Trailers

Other benefits include:

  • Reduced overtaking times (giving better safety)
  • More torque and power for
  • Heavy off road use
  • Beach / Sand driving

The extra cost of factory Turbo Diesels such as Toyota Landcruiser over the standard diesel makes the aftermarket fitment a very viable alternative. 4WD owners can buy the more basic diesel vehicle (ie ex government) and fit the turbo system, saving themselves huge amounts of money. If you tow a caravan, horse float or heavy trailer, a turbo diesel 4WD is the only viable option. Petrol powered vehicles are uneconomic in this use and the fuel costs will put a huge dent in your budget.

WHAT IS A TURBOCHARGER?

  • A Turbocharger is a combination Turbine and Compressor joined by a common shaft.
  • Super-hot exhaust gases from the engine pass through the Turbine, causing it (and the Compressor) to spin at high speeds.
  • The Compressor draws air through the air cleaner, compresses and feeds it to the engine for mixing with fuel.
  • The result of these events is greater volumes of air/fuel mixture entering the cylinders.
  • The engine, as a direct result, delivers considerably more power and torque than an identical capacity engine taking in air at normal atmospheric pressure.

WHY TURBOCHARGERS NEED PROTECTION

  • The waste gases which drive the Turbine come direct from the combustion chambers via the exhaust manifold at temperatures which can lift the Turbine to over 700C.
  • The Turbine spins at up to 100,000 rpm.
  • The Turbo shaft and bearings and the oil which lubricates them must withstand these conditions on a daily basis for long periods at a time.
  • At switch-off, Turbo temperature is high and lubrication to the bearings stops instantly.
  • Unless special precautions are taken, this may result in thermal distortions, the varnishing of oil on the shaft and bearings and premature Turbo failure.

Optional Turbo Timers and oil coolers should be considered depending on the make and model of the vehicle and your intended use.
