What Are Turbochargers
Turbochargers are a type of forced induction system that compresses the air flowing into the Internal Combustion Engines. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder.
A turbocharged engine produces more power overall than the same size engine without the charging. This can significantly improve the power-to-weight ratio for the engine. This also means that a smaller engine can produce higher horsepower more efficiently.
In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger usually spins at speeds around 100 times that of the engin. And since it is hooked up to the exhaust, the turbine also runs at very high temperatures.
Turbochargers allow an engine to burn moreg fuel and air by packing more into the existing cylinders. The typical boost provided by a turbocharger is 6 to 8 pounds per square inch (psi). Since normal atmospheric pressure is 14.7 psi at sea level, you can see that you are getting about 50 percent more air into the engine. Therefore, you would expect to get 50 percent more power. But it's not quite that simple and they're not always perfectly efficient, so you might get a 30-40 percent improvement instead.
The increase in horsepower from a turbocharger depends on several factors, including the size of the turbo, the type of engine it's paired with, and how the turbo is tuned. For instance, if the base engine produces 200 horsepower, a turbocharger could potentially boost that figure to between 240 and 280 horsepower.
One cause of the inefficiency comes from the fact that the power to spin the turbine is not free. Having a turbine in the exhaust flow increases the restriction in the exhaust. This means that on the exhaust stroke, the engine has to push against a higher back pressure. This subtracts a little bit of power from the cylinders that are firing at the same time.
