TURBO

How do turbo's work?
A  turbo is an air pump that is driven by the engine's waste

Turbochargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder or a rotor housing. More air means that more fuel can be added. therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging, which can improve the engine's power 100% and more what it originally was. 

In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger spins at speeds up to 150,000 rotations per minute (RPM) therefore it needs good lubrication-- that's about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high.

Turbochargers allow an engine to burn more fuel and air by packing more into the existing cylinders. The typical boost provided by a turbocharger is 6 to 8 pounds per square inch (PSI). Since normal atmospheric pressure is 14.7 PSI at sea level, you can see that you are getting about 50 percent more air into the engine. Therefore, you would expect to get 50 percent more power. It's not perfectly efficient, so you might get a 30 to 40 percent improvement instead.

One cause of the inefficiency comes from the fact that the power to spin the turbine is not free. Having a turbine in the exhaust flow increases the restriction in the exhaust. This means that on the exhaust stroke, the engine has to push against a higher back-pressure. This effectively subtracts a little bit of power from the cylinders that are firing at the same time.

The turbocharger also helps at high altitudes where the air is less dense. Normal engines will experience reduced power at high altitudes because for each stroke of the piston the engine will get a smaller mass of air. A turbocharged engine may also have reduced power, but the reduction will be less dramatic because the thinner air is easier for the turbocharger to pump.

Turbo is the sure thing to use for power improvement

BLOWER/SUPERCHARGER

What is a BLOWER or Supercharger?

 is anything that will force more air, or air/fuel mixture, into the cylinders of an engine than would be drawn into the cylinders naturally by the suction of the pistons during the intake stroke.
At sea level, atmospheric pressure is approximately 14.7 pounds per square inch (PSI) - air exerts this much pressure naturally on everything near the surface of the earth (because of the airs weight).
When an engine is "naturally aspirated" (unsupercharged), it must rely on atmospheric pressure to push the air into the carby, through the manifold, into the intake port, and then into the cylinder as the piston 'opens' the cylinder to maximum volume when it moves downward on the intake stroke.
So in the broadest sense a supercharger is any device or means for increasing the cylinder filling (volumetric efficiency) in an engine beyond that possible by the normal suction of the pistons; that is, beyond that possible under the force of atmospheric pressure. Therefore, instead of loading the cylinder with a partial air/fuel charge before compression and combustion, a blown engine can fill its cylinders with a supercharge which can attain or actually exceed 100% volumetric efficiency.

The Blower's advantage is that is driven by the engine's belt which gives u instant power(No lag)  the advantage on a turbo is that u get better top end power but it has lag.

NOS "NITRO"

There are three points. First, nitrous oxide is comprised of 2 parts nitrogen and one part oxygen (36% oxygen by weight). When the nitrous oxide is heated to approximately 572oF (on compression stroke), it breaks down and release extra oxygen, However, it is not this oxygen alone which creates additional power, but the ability of this oxygen to burn more fuel. By burning more fuel, higher cylinder pressures are created and this is where most of the additional power is realized. Secondly, as pressurized nitrous oxide is injected into the intake manifold, it changes from a liquid to a gas (boils). This boiling affect reduces the temperature of the nitrous to a minus .127 Degrees F. This "cooling affect" in turn significantly reduces intake charge temperatures by approximately 60-75 Degrees F. This also helps create additional power. A general rule of thumb: For every 10 Degrees F. reduction in intake charge temperature, a 1% increase in power will be realized. Example: A 350 HP engine with an intake temperature drop of 70 Degrees F, would gain approximately 25 HP on the cooling affect alone. The third point, the nitrogen that was also released during the compression stroke performs an important role. Nitrogen acts to "buff or dampen" the increased cylinder pressures leading to a controlled combustion process.
