How Turbo Chargers are different from Super Chargers

How are Turbochargers different from Superchargers

Turbo chargers

Turbochargers are a way of forced induction for an engine to give an extra boost to the vehicle using the waste energy from the motor, i.e. from the exhaust gases. Turbochargers, are connected to the outlet of the exhaust gases from the combustion chamber. Thus, when the exhaust gases leave, they do have some heat energy left in them which is used to rotate the turbo turbine inside. This in turn is converted to energy by the turbine, which is used to power the vehicle. This is called the turbo boost.

The concept of turbocharging is impressive because this allows the engine to generate more power in the same cubic limit and also enhance the fuel efficiency. So all in all turbos are incredible; but then when we take that from a motorcycle perspective, there are certain issues that come up.

Super chargers

Superchargers function on the principle of forced induction to raise the power of the vehicle. They don’t use the exhaust gases like Turbochargers, but in turn use the power from the engine itself. The supercharger is connected with the crankshaft of the engine and draws power directly for its functioning. It is logical to deduce that there should be a drop in the engine power and not power boost. This is only partially right. The overall power conveyed to the crank does decrease, which is similar to when you switch on the AC of the car and the power to the wheels drop a bit.

The power generated in a supercharger may be less than that of a turbocharger, but it does give the vehicle a notable boost by using the energy drop at the crank. Also there are no lags in superchargers like turbos. The power amplification in superchargers is very high and most importantly they don’t have a threshold to deliver power. They can do so from the word go.
