Superchargers
A supercharger, often referred to as a “blower”, is a mechanism for forcing or “blowing” air into an internal-combustion engine in order to increase engine power. The power of an engine is directly related to the amount of air it can consume, mix with fuel, and burn in its cylinders, and therefore the more air that can be forced into the engine, the more power the engine can produce. However, in a non-“blown” engine, only a certain amount can be forced in. In order to understand the workings and importance of a supercharger, we must first be familiar with how a normal or stock engine’s intake works.
A four stroke engine is the kind most commonly found in automobiles, and operates in four distinct steps or “strokes”; induction, compression, combustion and exhaust. On the first stroke, the piston moves downward and causes a pressure in the cylinder which is less than the atmospheric pressure outside of the engine. As a result, the air outside of the engine moves into the cylinder where there is less pressure, and is actually forced in because of the now higher pressure outside of the piston. On the second stroke, the piston moves upward and compresses the air with gasoline. The sparkplug ignites the mixture which combusts and moves the piston downward for the third stroke. This is where the power of the engine comes from. The piston then returns upward for the fourth stroke in order to push out the exhaust gases. Because the power of an engine is dependent upon the volume of air that can be drawn into the cylinders, it becomes limited at a certain point when the cylinder reaches its maximum negative pressure, and no more air can be sucked in. Not even an efficient engine, which at best is said to be on...

“What is the difference between a turbocharger and a supercharger on a car's engine?” Howstuffworks.com. ©1998-2002 Howstuffworks, Inc. 30 November 2002. http://www.howstuffworks.com/question122.htm.
...the shock waves created by a shift, which acts as a brake, slowing the turbo and requiring it to be spooled up again. We lose boost pressure but keep our turbo speed this way.
The first type of forced induction system is the turbocharger. A turbocharger is essentially the same as a supercharger, except where they get their power from. A turbocharger is powered by exhaust gasses that have been produced by the engine and are forcing their way through the turbofold, or the exhaust manifold that the turbo is housed in. The exhaust gas pushes its way through the turbocharger and hit the turbine wheel. Vehicles that usually find the need for a turbocharger from the factory are four or six cylinder engines. Standard in most European vehicles such as Mercedes, Audi, Volkswagen and Volvo. These cars are known for their small displacement motors, and great gas efficiency, due to this setup...
Ok, we've seen it brought up a million and one times, so, I'm going to give my take on the whole turbo vs. supercharger arguement once and for all. Honestly, both devices ROCK. They essentially do the same thing (which is pressurize the intake) when it comes down to it. Argueing that one makes "more power" than the other is utterly redundant, as I re-iterate that they both essentially do the same thing. (Look up redundancy in the dictionary and it will say "See Redundant".) Anyways, I'm going to write this blurb based on the assumption that anyone reading it has grasped the basic concepts of how a turbocharger and supercharger work.
As you are driving, you see many cars going over the speed limit. Many of the drivers are into racing and modifying their cars. In most cars there are two major modifications that can be done, they are; turbo kit, or a nitrous kit. Both increase horsepower dramatically, but one is instant and the other goes into effect after a certain rpm.
3.Combustion: As the piston reaches the top of its stroke or TDC, the spark plug fires, igniting the mixture. Due to the high compression of this mixture it is very volatile and it explodes when the spark is introduced. This pushes the piston downward and produces power.
Starting from the point where the spark plug fires. Previous to this, the piston has compressed the fuel/air mixture in the cylinder. When the spark plug fires, it creates an explosion. This explosion drives the piston downward which turns the crankshaft, which is attached to the shaft that drives the cutting deck on the lawn mower. As this is happening it is compressing the fuel/air mixture that has come from the carburetor, in the crank case. As the piston starts to go down, the exhaust port is uncovered, and the pressure in the cylinder forces most of the exhaust gases out of the chamber.
The light turns red and you slowly come to a stop driving your 1992 GMC Syclone equipped with a 280 horsepower 4.3 liter V-6 teamed up with a four speed automatic transmission. The GMC Syclone is basically a sporty run-off of GMC's Sonoma. In the next lane, a brand spanking new Ford Mustang equipped with a 320 horsepower 4.6 liter V-8 pulls up. You seem to be feeling pretty spunky today, so you rev your engine signaling to the driver of the Mustang that you want to race. The other driver looks over, gives a glance at your GMC Syclone and begins to laugh. However, he goes ahead and revs his engine giving the go-ahead for a race.
As the trend of high speed vehicles catches on in India the applications of this supercharger will increase significantly. This technology allows us increase the power of a bike without making any significant changes to the engine itself. It also allows us to make the engines smaller without having to compromise on the power.

Throughout this paper the V6 and V8 engines will be compared. The V style engine is the most popular engine configuration. Although the V6 engine is made to perfection, the V8 is better because of the hidden features it has. After reading this paper about the comparison between both engines, you should have a decent understanding of why the V8 is better than the V6.
So what are turbos and superchargers? Both are used to suck in more air than a naturally aspirated car, (one without modifications), to compress air and send it into the combustion chamber, which creates more power. Turbos do this by utilizing the exhaust gasses from an engine to spin a turbine which then pulls in the air through an intercooler to cool the hot exhaust air which is then put back into the engine. A supercharger is mounted on top of the engine, and is coupled with a pulley which is then connected to the crankshaft of the car via a belt. As the car’s crankshaft turns, the screws of the supercharger are spun, which suck in more air at the expense of how fast the crankshaft is going.
A 4 stroke engine has four steps to complete one cycle. First, there is the intake stroke; this is where the fuel mixture is pulled down into the engine. Second, there is the compression stroke;
There are many differences between Turbos and Blowers. The first is the power curve. Superchargers build boost as rpm increases in a linear fashion, because they are belt driven from the engine crankshaft. This means that the supercharger is always on and achieves its maximum potential at higher rpm's. The faster the engine is going, the faster the supercharger is turning. T...
The purpose of this paper is to review on how physics can help to improve motorcycle performance. I currently own a 2003 Harley Davidson VROD. It came from the factory weighing in at 683.3 lbs (dry) or 285 kg. The VROD has a wheelbase of 67.2 inches or 1710 mm. The Engine that resides in the VROD is an 1130cc German designed performance engine developed by Porsche that has a winning stature in the racing world. The VROD is claimed to have a 115 horsepower or 86 kW of power at 8250 revolutions per minute (rpm) at the crankshaft. It also claims to have 84 foot ponds of torque or 113.9 N-m at the crank. All that information translates into that the VROD line of motorcycles are long, low, and very fast compared to other larger displacement motorcycles of that style. With such a high tech engine, I feel that more power can be tweaked out of it to help improve miles per gallon (mpg) horsepower, and torque. We will first begin with air intake performance. A stock air flow filter allows a set amount of air flow to pass thru the combustion chambers of the engine. But as we all know more ai...
The invention of internal combustion engines in the early 19th century has led to the discovery of utilisation of cheap energy that is petroleum and this enabled the world to develop and progress into the modern world today. Humans were able to accomplish more work done with little manual labour, using internal combustion engines powered by fossil fuels. Internal combustion engine are mechanical power devices that convert heat energy to mechanical energy with the combustion process taking place in a system boundary (Rolle, 2005). Among the internal combustion engine invented in the 19th century were the Otto engine, Diesel engine and gas turbine engine. Gas turbine engine is one of the popular engines used today due to its high torque per weight ratio relative to other types of internal combustion engines. As explained by Cengel and Boles (2011), the gas turbine engine works on a 6 stages process, namely air intake, compression, fuel injection, combustion, expansion and exhaust (refer to Figure 1 in Appendix 1).
