This force-feeding of oxygen let the engine burn more fuel and jet more power, and is usually augmented with an improved exhaust system as well.
A supercharger, when we talk about a basic one is called a Roots supercharger, because it is usually installed right where the intake manifold is.
It uses spinning mesh lobes that throw air from one end to the other, and the pressure builds up inside the intake manifold, letting in a gush of air in bursts. Roots superchargers are what you see bulging out of the hoods of classic cars. Another kind of supercharger is a twin-screw one, that whirls and draws in the air in a corkscrew fashion.
The air is compressed and then forced into the engine this way. The pros of a supercharger are that they have been in the market for donkeys' years and there is a large variety to choose from, to suit every need, car, and budget. A simple nudge to the gas pedal provides an instant burst of power, which makes racing all that more fun and winning.
That said; superchargers can be bulky and may require alterations to the hood of your car. Plus the air it feeds into the engine is not a consistent stream and so power may surge and lag accordingly. If you need instant power and need it cheap, minus any lag, superchargers would suit you a lot better. Procharger is the brand name of a centrifugal supercharger that works differently than a basic supercharger and delivers a consistent stream of air to your vehicle.
Prochargers, use an impeller, a rotary device that sucks in the air by rotating at fast speeds. When the air reaches the center of the impeller, it gets distributed in an outward, cyclic manner by a strong centrifugal force where a diffuser turns the air into high pressure. A Procharger will use centrifugal force to obtain power. After the charger gets its energy, that power is then transferred to the engine.
The type of charger you select will determine how it is mounted, how the energy is obtained and passed to the engine, what the effect is on the engine and how the charger will be mounted. A Procharger works using centrifugal force. The Procharger uses an impeller which spins at a high speed.
This action causes air to be drawn into a small compressor housing. This forces additional oxygen into the engine. This type of charger is usually attached to the front of the engine with a type of bracket. A Supercharger is attached to the front of your engine with bolts. When the engine spins, it spins the Supercharger. When the Supercharger spins, it forces air into the engine. How much extra power your engine will get will depending on the size of the pulley being used. In this case, remember that a smaller pulley will move faster, therefore creating more energy.
A Turbocharger works by utilizing an exhaust housing. This allows the charger to use the exhaust produced by your car to spin a turbine. This turbine then makes the compressor force air into the engine of your car. A Supercharger is pretty limited. It will only produce power as your engine is running. And since it needs the power your engine is producing in order to make more power, it is pretty limiting.
You are essentially using horsepower to make horsepower. Another concern involves the possibility of blowing hot air in to your engine. This can cause problems and issues with your engine that have the potential to be worrisome. A Turbocharger can have a delay in transmitting the power to the engine. This is known as turbo lag.
The rotor lobes on a twin-screw have a conical tapering to them which compresses the air squeezing it into a smaller place as it moves from one side to the other. Some, but not all, twin-screw superchargers go on top of the engine much like a roots supercharger. The twin-screw is much more effective than roots. Because of that, it is going to come at a higher price tag. Twin-screw superchargers are also known to be particularly loud, so some sort of noise suppression system will need to be implemented.
Prochargers are essentially highly powerful, precise, brand name centrifugal superchargers that adds plenty of power to your car. They work much differently than your average supercharger and are considerably more efficient.
Instead of a rotor, Prochargers use a fast-moving impeller to pull air in to be compressed. The air reaches the center of the impeller and gets radiated outward by strong centrifugal force.
From there, a diffuser surrounding the impeller turns the air high pressure. All of the molecules in the air calm down and reduce the intense velocity of the air coming in while increasing the pressure.
Prochargers are also smaller and less obstructive. Overall, they will give you much more power at more rpm. Without a doubt, adding a Procharger or supercharger to your car is going to add some nice extra power to it, but in choosing which one will maximize the performance that you are looking for, there are a few things to consider. Being able to add horsepower to your car automatically ramps up the power, but how responsive your pedal is to that power can play a role. Superchargers suffer from zero lag.
That means that the power will come straight at you when you put your foot to the pedal. If you are looking for immediate power and pedal response, superchargers may offer the performance you want. Prochargers, on the other hand, offers a linear and smooth build easing you into the power that it is has to offer. Giving that added horsepower to your car can be enticing, and while it can do wonders in adding value to your car, price is very important.
You want to be able to give it that extra boost without breaking your bank. While weighing the cost of how much you are going to spend, there are certain things that you should keep in mind before choosing one over the other. How you want to use it is a big one.
If you are an absolute speed demon looking to see just how fast you can go from 0 to 60, then a classic roots supercharger may be for you. Unless you are able to be in a situation where you can safely and legally take your supercharger to its highest level, it might be more practical for you to go with a Procharger.
