The main differences between Turbocharger and Supercharger are Turbocharger is driven by the exhaust gas of an engine, whereas The supercharger is directly driven by the engine through a belt drive.

Before moving to further detailed explanation lets have some overview of Turbocharger and Supercharger.

Note: At the bottom of every article the PDF link is attached make sure if you want you can easily download.

Difference Between Turbocharger and Supercharge:

Here are the 10 Points on the difference between Turbocharger and Supercharger:

Sl. NoSuperchargerTurbocharger
1.It is directly driven by the engine through a belt drive.It is driven by the exhaust gas of an engine.
2.Supercharger generates more noise.It generates less noise because it used exhaust gases.
3.The supercharger is more costly than the turbocharger.The turbocharger is less costly.
4.It is not essential to use inter-cooler in the supercharger.Because turbocharger work by exhaust gases so inter-cooler is essential.

And the 6 Point are:

5.It increases engine power by about 30-40%.It increases engine power by about 30-50%.
6.The supercharger uses the useful power of an engine to drive the compressor.The turbocharger uses the power of exhaust (waste power) gases to drive the compressor.
7.The supercharger is connected by the crankshaft, so it starts working suddenly as the engine start.Turbocharger used exhaust gases to operate, so it does not work until sufficient smoke is generated by the engine.
8.A supercharger is a unit that is bolted to the engine and connected with a belt drive between a crankshaft and the supercharger unit.A turbocharger is similar to a supercharger, except it has an exhaust housing instead of a belt drive, and runs by exhaust gasses.
9.Because it uses the useful power of the engine so it decreases the engine efficiency.Because it uses exhaust gases to drive the compressor, resulting in increased efficiency.
10.The supercharger is difficult to adopt in the car because it occupies a large space.When we considered design, the turbocharger is compact and easily adapted in the cars.

So this our short presentation on the comparison between Turbocharger and supercharger, I hope you like it if so, let me know your thoughts in the comment section.

FAQ:

What is Turbocharger?
