Blower vs Supercharger: Advantages, Disadvantages, and Cost

When it comes to boosting the performance of your engine, there are two popular options that often come up: blowers and superchargers. But what exactly are the differences between these two power-boosting devices? In this article, I’ll break down the key distinctions between blowers and superchargers, giving you a clear understanding of how they work and what sets them apart.

First, let’s talk about blowers. A blower, also known as a mechanical supercharger, is driven by a belt connected to the engine’s crankshaft. It uses a set of gears or a rotor to force more air into the combustion chamber, resulting in increased power output. Unlike a supercharger, which is typically mounted on top of the engine, a blower is often located in front of the engine, drawing in air from the outside and compressing it before sending it into the intake manifold.

On the other hand, a supercharger is an air compressor that is directly driven by the engine’s crankshaft. It uses a belt or chain drive system to spin a compressor wheel, which forces more air into the engine. Unlike a blower, a supercharger is typically mounted on top of the engine, sitting on the intake manifold. This allows for a more compact design and easier installation.

While both blowers and superchargers are designed to increase engine performance, they differ in terms of their location, drive mechanism, and overall design. Understanding these differences will help you make an informed decision when it comes to choosing the right power-boosting option for your vehicle. So, let’s dive deeper into the specifics of blowers and superchargers and explore the advantages and disadvantages of each.

How does a Supercharger work?

A supercharger is a device that forces more air into the engine, allowing it to burn more fuel and generate more power. This extra air is achieved by using either a centrifugal force or rotating lobes called rotors.

Centrifugal superchargers use a compressor that is driven by a belt connected to the crankshaft. As the engine spins, the compressor draws in air and pushes it into the engine’s intake manifold. This creates a higher air pressure, resulting in more air/fuel mixture entering the combustion chambers. The compressed air allows for a stronger and more efficient combustion process, which translates into increased horsepower and torque.

On the other hand, positive displacement superchargers such as those with rotors, function by drawing air into cavities, trapping it, and then squeezing it out into the engine. These rotors rotate at high speeds, creating compression and pressurizing the air that enters the engine. The result is similar to the centrifugal supercharger, with increased air density and improved engine performance.

One of the advantages of a supercharger is its ability to provide instant power. Unlike turbochargers that require exhaust gases to spin the turbine, superchargers are driven directly by the engine, providing immediate boost and response. This instantaneous power delivery is highly beneficial in applications where quick acceleration is crucial, such as in racing or high-performance vehicles.

Additionally, superchargers offer consistent power delivery across the engine’s RPM range. Unlike some other performance modifications that only provide benefits at high RPMs, a supercharger is effective at all engine speeds, ensuring a smooth and powerful driving experience.

Moreover, superchargers increase low-end torque, improving the vehicle’s responsiveness and drivability. This is especially valuable in applications like towing or off-roading, where low-end torque is necessary for overcoming obstacles or pulling heavy loads.
