When it comes to high performance engine upgrade, the goal is to get the power from the engine as much as possible while at the same time maintain or improve the efficiency of the machine. One upgrade that will increase the output of the machine is a supercharger. Superchargers are essentially air compressor that forces compressed oxygen into the air intake of the engine combustion. Added oxygen burn more fuel per engine cycle, which in turn increase the power output. Superchargers are powered mechanically by the engine through the crank axis the belts, gears, chain, or the shaft or axial or radial gas turbines. There are two main types of superchargers added to high-performance machines, positive displacement and dynamic.
The difference between these two kinds of superchargers are the methods of compressed air. The first type is a positive displacement. Positive displacement Superchargers put pressure on rate constant virtually fixed at all speeds and usually mechanically supported. The air is divided in the supercharger and saved bit by bit into the machine. Positive displacement Superchargers has four main types of pumps, Roots, Lysholm twin-screw, slide the propeller, and the types of reels or G-Lader supercharger. The pump breaks down further into external and internal compression pump.
Roots superchargers have a compression pump is external. This pump allows the pressure in the intake manifold to cope with the pressure coming from the supercharger that causes pressure to flow back into the supercharger. What is backflow pressure compresses the gas power plant. These pumps are not as efficient as internal compression but efficient in moving air at low pressure difference.
Other types of positive displacement pumps use internal compression to a certain extent. Internal compression pump compresses air in the supercharger and save them into machines smoother on fixed compression ratio. Compression ratio must support because if the pressure of the supercharger boost pressure exceeds the compression of the engine, the supercharger backflow will occur that take away from the efficiency of the machine. Internal compression superchargers must match or exceed the thrust of the engines for maximum efficiency.
Another type is a dynamic supercharger compressor. Unlike positive displacement superchargers, dynamic compressors provide higher pressure at higher speeds and are usually powered by gas turbines. They stimulate the air to a high level and exchanges speed with the engine to the air pressure. Therefore, the other is a pressure machine, the air speed supercharger would yield to exchange with the machine.
Superchargers and turbochargers are both working to improve the power output of the engine but supported differently. The main difference was that superchargers are powered directly by the engine when the turbocharger is powered by the exhaust from the engine. Turbochargers can get more power and fuel efficiency that is higher than the superchargers but superchargers have a higher throttle response and can achieve a top speed more quickly. This is because the feed from the exhaust turbocharger was not strong enough at first to power turbochargers to achieve high RPM. If the exhaust is strong enough to start the turbocharger, increasing the lead to even more exhaust turbocharger to provide more power, leading to a surge in the output of a sudden speed and power after a slow start. Turbocharger does not apply a boost proportional to the RPM such as superchargers.
Adding a supercharger to the engine's high performance is a good way to increase the power output. Engine-driven nature of the supercharger that makes it possible to reach top speed faster and more smoothly than turbochargers. Superchargers also work more efficiently when they have a higher pressure ratio of the engine.
