What are pros and cons of turbocharging small capacity engines?

Turbocharging is a very effective way to get the most out of an engine.

Lets start with the pros:

  • More power. – A turbocharger pushes more air into the engine cylinders , which means better combustion and a more powerful boom which results in more horsepower.
  • Faster acceleration– Just because the engine is getting more air and a better and a more powerful combustion, torque figures significantly increase even in the low end. This makes the car accelerate faster than a naturally aspirated engine.
  • Recycling waste power– As turbochargers work work mainly because of exhaust gases, the power of exhaust gases which otherwise gets useless, gets useful just because of turbocharging and gives more power.
  • More efficient use of space – this one certainly is the reason for car manufacturers to put turbochargers in their small engines. A turbocharged engine creates more power and torque than their naturally aspirated (non turbocarged) counterparts. To match the power and torque figures, you need a bigger engine. And hence , a smaller engine with a turbocharger fills the need and also saves space in the engine bay and also reduces the weight of the vehicle.

Now let’s have a look at the cons

  • TURBOLAG!!– The main villain in the story of any turbocharger. So, what really happens is, when you turn the engine on, it takes some time to create as much exhaust gases that is needed to spool up the turbocharger and create boost. Generally most of the General turbochargers spool up after around 1500–2000 rpm which makes the car feel underpowered before the spooling rpm. And the moment the turbocharger stars boosting air, engine gets the solid boom and you go faster.
  • Engine gets unreliable and engine life also gets affected. The engine is certainly more highly stressed so any built in engineering problems will show up faster.
