Best Advice on Choosing the Right Turbocharger

by  |  On October 28th, 2016  |  In Tips & Guides

There are many things that you need to consider while choosing the right turbocharger for you vehicle. North East England’s largest engine cooling and climate control firm, Advanced Radiators has some good tips to help you make the right decision.

Why use a turbocharger?

The engine mixes air and fuel to enable a car to run smoothly. A turbocharger can improve the efficiency by forcing more air into the cylinder. The more air mixing with the fuel, the better will be the engine’s performance.

Now, this is not the only reason why you should use a turbocharger. A turbocharger uses less fuel but generates the same amount of power as a normally aspirated engine. Other than this, a car with a turbocharger feels stronger, as it distributes more torque to the engine.

The Turbocharger Lingo:

Now that you’ve known what a turbocharger can do to your car, it is necessary that you understand some terminologies related to this amazing technology:

  • A/R ratio — Stands for area/radius ratio. A/R ratio is related to the properties of the compressor and the turbine housing’s curved scroll.
  • BOV — Short form of blow-off valve. BOV is a valve that releases pressure in a blow-through system when throttle backs off abruptly. It is present on the opening of the compressor.
  • Boost — Boost is the amount of pressure that lies above the atmospheric pressure. It is measured in bars (b) on the metric system. In the US system, it is measured in pounds/square inch (psi).
  • Choke flow — It is the compressor wheel trim and housing combo’s maximum flow at a particular efficiency.
  • Compressor — The cold air that goes into the engine side of the turbocharger where intake air will pass on the to the car’s engine.
  • Compressor surge — It is where the air reverts out of the front of the turbocharger. Compressor surge happens when there is excessive pressure during the boost or when the throttle shuts and air is stuck between the compressor and the throttle plate.
  • Intercooler — Lies between the turbocharger and the car’s engine. Intercooler can be an air-to-air or an air-to-liquid heat exchanger which cools down the compressor under boost.
  • Lag — Lag occurs when there’s a pause between a change in throttle position and the production of usable boost.
  • Turbine — It is the exhaust of the turbocharger.

How are intercoolers beneficial?

Intercoolers are an important part of a turbocharger, so it is essential to discuss their benefits.
Turbochargers become more powerful because of the intercoolers. If your turbocharger has a poor intercooler system, it will affect the efficiency of your engine.

If you don’t want to your engine to perform poorly, avoid pressure drop. It is a process that lets the pressurized air drop some of its pressure while it moves across the intercooler. This happens due to aerodynamic deficiency. This handy guide will help you learn how you can avoid this problem.

Now that you are aware with the turbocharger technology and how it can make your car stronger and more fuel-efficient, you can confidently order one for your car.
