Ways to go Faster Part II

Wow... It's been almost six months since I've posted something on this blog. Sorry to anyone who is reading this. I've been extremely busy with school and haven't had much time to post on this blog. Anyway here is the continuation to Part I:

Expensive Mods:

Turbo/Super Charger: Both of these systems work on a similar concept. They are used to increase the amount of air that is taken into the engine by compressing the air that is being taken into the engine. In comparison to a cold air or short ram intake system there is a dramatic increase in the amount of power that is produce. In most car applications a turbo charge can lead to a 30 to 50 percent increase in horsepower. A short ram intake is used because it does not require as much space as a cold air intake. Another reason is the fact that the air will be heating up and then cooled as it enters the intercooler. So there isn’t a need for cold air being taken in thorough the blower.
There are only a few differences between them. The turbo was original used in air craft to increase the amount of oxygen that was being taken into the engine. Another major difference is the fact that the super charger provides a large amount of power at low engine speeds while losing power when engine rotation exceeds about five thousand RPM. A turbo charger does the exact opposite. It produces low power at low engine speeds but produces large amounts of power once engine rotation exceeds about 2500 RPM. Yet another difference between a turbo charger and a super charger is the fact that a super charger is belt driven which means that it relies on the engine to produce the energy needed to turn the blower to create compression. This decreases the overall amount of power produced by the engine up to 30 percent.
Before adding a turbo or supercharger there are some major modification that must be done to the engine. These modifications consist of remapping the electronic control unit, relocating certain engine components, fabricating mounting brackets, installing a boost controller, and adding larger fuel injectors. Remapping the electronic control unit is essential because it will effect how the car will perform over all. It determines how long the intake valve will be open during the intake stroke, the amount of fuel injected, as well as how long the spark will last during the combustion stroke. Relocating certain components is essential when adding a turbo or super chargers. It is essential because space must freed for the additional piping needed to connect the blower and intercooler to the engine. A component that is commonly moved during installation is the battery. Mounting brackets need to be fabricated to house the relocated equipment. Larger fuel injectors are required to keep the engine from running lean. One of the most important modifications that must be preformed when adding a turbo or supercharger is installing a boost controller. A boost controller controls the amount of air taken into the engine to prevent a loss of power and running lean. A boost controller takes control of the waste gate to reduce the amount of turbo lag. It also allows greater control over the amount of air being taken into the engine. This means better response when the throttle is applied. With better control over the intake prevents detonation also known as knocking. Detonation can severely damage an engine and render it unreliable or useless.


Engine Swap:If none of these other methods work for You, you may want to try an engine swap.
