Force Induction
Forced Induction

There are really two different forms of forced induction.
The turbo charger, and the supercharger.

Things you will need to know about forced induction.
1. Forced Induction is not very everyone, so make your choice wisely.
2. It is very expensive.
3. Yes it does provide you with mass gains, but that also means more things can break.
4. If you get in a wreck, without informing your insurance company that your vehicle has a forced induction system on it, you're screwed more than likely.
5. It does require more maintenance.
6. You absolutely must build up your vehicle to hold the set up. Having a few minor modifications won't cut it.

Detonation, Knock and Pre-Ignition

There is a very little difference between Detonation and Pre-Ignition. Detonation is actually fuel combusting from the heat and pressure of the combustion chamber. Pre-ignition is an alternate source igniting the fuel (a hot spot in the combustion chamber, a sharp point, etc). Pre-Ignition is very much like an over advanced timing. Both of these could occur before or after the spark, it doesn't really matter.

Knock and detonation is the same thing. The actual sound of knock is the pressure waves inside of the cylinder, piston, and valves. If you hear a knock, you have a problem.

The only way to solve this problem is to adjust the mixture. If you add more air, you need to add more fuel at the proper ratio.

Compression
The pistons inside of an engine all compress the air and fuel at a certain rate. The higher the compression rate is, the more power the motor will make, but this also means the internals are under more strain, and are performing with more heat. A high compression engine does not make for a very well force induction system. The added strain of a force induction system, and the increased pressure in each cylinder can create enough stress to damage the motor. A lower compression engine on the other hand, can handle far more boost because it is under less stress and the compressor does not have to work as hard to push the air into the cylinders since less air in there to begin with.

How they Work
The Super Charger and the Turbo Charger both work with the same theory and rules of science; the only real difference in how they work is the power source. The Super Charger is a belt driven unit, and the Turbo Charger uses a turbine and shaft that is spun by the exhaust stream to increase the rpm's of the blades.

and
The Turbo Charger

Little extra strain on the motor
Boost lag
Takes no power to make power
Obtains power from exhaust stream
Usually Harder Installation
Usually costs less
Causes back pressure on exhaust
More common (easier to find parts)

The Super Charger

Does add extra strain on the motor
Instant Boost
Has to take power to get power
Obtains power from a belt pulley
Usually easier installation
Usually more expensive
Less common (harder to find parts)
Far less piping
