MODIFY YOUR CAR

To modify your car for better performance costs money and time, and requires a great deal of knowledge to do yourself. Car power is determined by the amount of air and fuel burned. I will introduce you to some of the modifications you can consider to increase your car's power, especially the amount of power the engine can deliver at low RPMs, resulting in greater acceleration ability.

THE ENGINE
The basic way all engines work is to suck in a mixture of fuel and air, compress it, ignite it either with a spark plug or by self-igntion in the case of a diesel engine, allow the explosion of combusting gasses to force the piston back down and then expel the exhaust gas. The vertical movement of the piston is converted into rotary motion in the crank via connecting rods. The crank then goes out to the gearbox via a flywheel and clutch, and the gearbox sends the rotary motion to the wheels, driving the vehicle forward. Engines are devices that burns fuel to produce mechanical power and convert heat energy into mechanical energy.

COLD AIR INTAKE
Cold air intake systems bring air temperatures down and makes cold air. Cold air is much denser than warm, humid air. Cooler or cold air holds more oxygen for any given amount. The more oxygen going into an engine equals the more powerful the combustion. Air intakes gives more horsepower with the same or better fuel economy.

Forcing your engine to ingest its combustion air from under the hood, through a restrictive airbox and stock paper air filter gives away free horsepower. A cold air intake will restore lost engine power. Cold air intakes route intake plumbing away from hot underhood and engine areas, and deliver air through a free flowing air filter and smooth intake passages. Resulting in cooler, denser air delivered in greater quantities at higher velocities to your throttle body. Denser air, and more of it, equals power.

FUEL SYSTEM
A fuel system is an essential component on a car or other internal combustion engine device. Fuel has to be pumped from the fuel tank to the engine and delivered under low pressure to the carburetor or under high pressure to the fuel injection system. Some fuel injected engines have two fuel pumps for this purpose: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine.

GEAR BOXES
The simplest gear box or transmissions consist of a system of interlocking gearwheels. These wheels are arranged so that by operating a lever the driver can choose one of several ratios of speed between the input shaft and the output shaft. These ratios are called gears, first gear being the arrangement that gives the lowest output speed, second gear the next lowest, and so forth. To allow smooth shifting from one gear to another, a clutch is provided to disengage the engine from the transmission. The commonly used dry single disk clutch has a steel disk with a friction lining that is sandwiched between a flywheel on the engine shaft and a pressure plate on the transmission input shaft. When the driver takes his foot off the clutch pedal, springs squeeze the friction disk into the space between the flywheel and the pressure plate, enabling the engine shaft to turn the transmission.

Suitable torque, or turning force, is generated by the engine only within a narrow range of engine speeds, rates at which the crankshaft is turning. However, the wheels must turn with suitable torque over a wide range of speeds. While its speed is held roughly constant, the engine turns an input shaft on the transmission or gear box whose output shaft can be adjusted to turn the wheels at an appropriate speed.

Your typical exhaust setup has kinks and bends in it to make it fit the engine compartment and under the car. In some cases these can be smoothed and straightened out somewhat but more often than not, the exhaust has to take the same route as stock. In this case, the best option is for a larger exhaust. Larger diameter exhaust pipes can accommodate more gas flowing through them and hence provide less constriction to the engine when it is blowing out exhaust gasses. Typically a factory exhaust will have two constriction points. There will likely be the catalyser at the front where the exhaust is hottest and makes the catalyser work best and a muffler can at the back. High flow cat back exhaust systems are so called because the start at the output of the catalyser and replace all the exhaust from there back. They will have larger diameter pipes and a high-flow muffler at the end. Alternatively you can get header back exhausts which replace everything from the exhaust header to the back, typically removing the catalyser in the process. These are sometimes affectionately referred to as catless or no kitty exhausts.

MUFFLER
Car mufflers one weakness is its vulnerability to corrosion. Original equipment mufflers usually have stainless steel head muffler pipes and converter shells, and aluminized pipe to resist corrosion. But after three or four years, the muffler and tailpipe often need to be replaced. Many newer vehicles are equipped with stainless steel mufflers that typically last 7 to 10 years.

If you've ever heard a car running without a muffler, you know what a huge difference a muffler can make to the noise level. Inside a muffler, you'll find a deceptively simple muffler with some holes in them. These muffler chambers are actually as finely tuned as a musical instrument. They are designed to reflect the sound waves produced by the car engine in such a way that they partially cancel themselves out.

Located inside the muffler is a set of muffler parts. These muffler parts are designed to create reflected waves that interfere with each other or cancel each other out. The exhaust gases and the sound waves enter through the center muffler part. They bounce off the back wall of the muffler and are reflected through a hole into the main body of the muffler. They pass through a set of holes into another chamber, where they turn and go out the last tailpipe and leave the muffler.

Rims are mostly made from aluminum alloy but some very high end rims are made of carbon fiber, and some old or very low-end rims are made of steel. Rims have even been made of wood and thermoplastic. The number of spoke holes on the rim normally matches the number of spoke holes in the hub. Some unusual rim designs have no holes for spokes.

Rims meant for use with rim brakes provide a smooth braking surface, while rims meant for use with disc brakes or hub brakes sometimes lack this surface. Rims can either have a single wall or double wall cross section. Single wall rims are usually less expensive and weaker. Double wall rims tend to be stronger and more expensive. Double wall rims may have a deep profile either to reduce aerodynamic drag or for additional strength, especially in the case of few spokes.

Suspensions are the portion of a vehicle that connects the wheels to the frame and controls ride quality and handling. Most suspensions feature coil springs or leaf springs, shock absorbers or strut bars, anti sway bars and a system of linkages, such as control arms, torsion bars, 4 links or trailing arms.

Suspension kits are group of components designed to modify a vehicle's suspension. These suspension kits might be intended to smooth the ride, improve handling, reduce body roll or alter the vehicle's ride height by using lift kits or lowering kits.

Bodykits or body kits are collections of exterior body kit modifications to a car, typically comprised of front and rear body kits and side skirts. There are many companies that sell these body kits as alternatives to the traditional look of the vehicle from the factory. Many advantages to body kits include better aerodynamics as well as having a high degree of aesthetic value. Body kits will be designed to complement each other, and work together as a complete design. Despite this, the 'mix and match' approach is often seen on cars, where the front of one body kit will be matched with the rear body kit of another.

Automative body kits are usually constructed of either fiberglass or polyurethane. Most car modification entusiasts prefer polyurethane body kits because it is more resistant to damage, and does not crack in cold weather. In some cases, body kits may also be constructed of carbon fiber, which is a popular, lightweight material. This type of body kit modification is not as highly regarded among speed enthusiasts, though, because it is very costly, and the difference in weight is minimal, versus changing other parts such as the hood or trunk.

SPOILERS
Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles, as well. Some spoilers are added to cars primarily for styling purposes and have either little aerodynamic benefit or even make the aerodynamics worse.

Although the most recognizable spoiler is the wing spoiler , there are actually many different types of spoilers.
A wing spoiler is an airfoil suspended above the body of the vehicle.
A lid spoiler (commonly trunk lid spoiler , lip spoiler , or boot lid spoiler ) is often a ridge of plastic or metal attached directly to the top of the trunk lid.
A roof spoiler is a small ridge of plastic or metal attached to the very back of the roof, usually just above the rear window.
A splitter is a spoiler attached to the front bumper, very close to the road surface, sometimes known as a "front spoiler" or on stock or stock-appearing cars as an "air dam."

Color shift paints are car paints that literally looks like a different color when viewed from a different angle. This paint contains light interference pigments, which make it possible to create thousands of color combinations from a single paint job. The light interference pigments often are mixed with conventional pigments. The light interference pigments may cause the paint to shift between two, three or more colors. This paint often can be applied to a variety of automotive surfaces, ranging from metal body panels to interior plastics. Some people are using color-shift paint just for graphics.

Car paint protection is a clear urethane or pressure - sensitive vinyl covering that can be professionally applied right over a vehicle's paint. The film conforms to the vehicle's shape and does not detract from the paint job, but rather provides a layer of protection against stone chips, bugs, abrasion and the sun. It typically is used to protect a vehicle's front end, wheelwells, door edges and bumpers, as well as a pickup's bedrails and tailgate.

AIR BRUSHING
Car airbrushing or airbrush painting is a painting technique that is used to create custom vehicle graphics. Airbrush painting is a paint scheme designed to set a vehicle apart from others like it on the road. Some airbrush graphics literally are painted on, while others are decals that can be removed or changed for frequent styling updates. Airbrushing graphics can range from a simple pinstripe to complicated designs and murals.

Car alarms work by emitting high - volume sound when triggered or when the car alarm circuit is breached. Car alarms are anti theft systems that sounds an alarm if someone tries to break into or steal a vehicle. Systems are offered with shock sensors, motion sensors and sound sensors. Some new systems include a pager that goes off when the alarm does, while others have anti-car jacking settings to protect the driver and the vehicle. Most alarms are set and disarmed using a remote, and because some professional thieves have figured out how to read the codes from a distance, many of the latest systems feature code-encryption or code-changing technology.

Car alarms can be designed to be triggered by vibrations, tilting of the car for the prevention of unauthorized towing, touching the car, the opening or closing of doors, sensing small but rapid changes in battery voltage or using volumetric sensors such as ultrasound or infrared.

The vast majority of car alarms are triggered by accident. They are caused by the passing of large vehicles, the vibration of the surrounding areas or people coming into contact with vehicle.

DASH KITS
Dash kits are made from different materials which includes carbon fiber and stainless steel. Dash kits come in a variety of colors and many are available with matching door trim kits. Most dash kits attach to the dash using special tape.

Woodgrain dash kits are decorative trim that features an adhesive backing and can be attached to a vehicle's dash. Each kit is custom designed for a particular vehicle to provide a perfect fit. Trim kits are offered in a variety of simulated and genuine woodgrains, with various clear and colored stains. There are also trim kits made from carbon fiber, stainless steel and other materials.

RACING SEATS
Car racing seats have safety car seat belts and multiple types of harnesses which help protect the driver. These car seats are made from strong materials and are very lightweight. Racing seats also provide the driver added support and protection from car accidents.

The following is a general guide to install racing seats into your car. We only provide these instructions to give you an idea of what you will need to do in order to install the race seats. We highly recommend that you have your racing seats installed by a professional experienced in aftermarket racing seat installation.

Removing Your Existing Stock Seats
Start with your driver side first and locate the four bolts that hold the car seat in, two up front and two in back. Starting with the rear two bolts of the car seat, remove the plastic covers over them and remove the car seat bolts. Be sure to recline the car seat so it is in an upright position and the weight is evenly distributed, so when you remove the front bolts of the seat it won't fall on top of you.

After removing the front two bolts, gently lean the whole car seat onto it's back and undo all of the remaining connections to it by locating the seat belt wire attached to the female end of the seat belt socket. You will also want to undo any electrical wires that were connected to the original stock seat. The most convinient way to remove the car seats is to roll it onto its side so it makes an "L" and swing the car seat out following with the back of the chair until it is completely out of the car.

With the car seat out of the car, look on the side where the cart seat belt receiver is. There is a plastic cover that you'll need to remove with a phillips screw driver, with one screw in front and one in back. With it removed, you'll see a bolt attaching the seatbelt to the seat. Remove this bolt. Now that you have the bolt off, put the plastic part back on.

Installing Your New Racing Seats
Assemble your racing seat brackets and sliders if they did not already come assembled. The pieces are made to face in a specific direction so don't install them backwards. Remember racing seat sliders have to face forward for your seat to move.

The aftermarket racing seat bracket will have holes for the racing seat belt receiver, so screw it in. You may need to remove some of the thick spacers so the racing seat will fit into your car, but do not remove them if you have room for them.

Attach the aftermarket racing seat bracket to your race seat before placing it into the car. Test fit and see if you like the height of the seat, adjust accordingly if you can. Don't be surprised if your new seat brackets that you ordered for your race seat do not fit the existing holes. This is very common because these seats are made to fit several makes of vehicles and not specifically to any one kind. Just make new ones after the test fitting.

If you have a race seat harness, attach the belts to them.

Not every race seat bracket is made the same. Attach the front bolts in loosely, then try to put in the rears. Use a hammer if you have to so the race seat bracket holes will line up. Just don't damage the bracket.

Securely tighten all of the bolts to the car. If you installed sliders and you can not slide the racing seat freely, check how you assembled it and reinstall it.

CUSTOM SHIFT
Custom shift levers are available in billet aluminum and chrome, as well as in other materials and finishes. The shift knob is a portion of a floor mounted shifter that the driver uses. Most shift knobs can be unscrewed and replaced easily. Replacement shift knobs are available wrapped in leather, vinyl or carbon fiber. They are also available in various shapes and sizes.

RACING PEDALS
Car racing pedals are made from different materials which includes carbon fiber and stainless steel. They come in a variety of colors and many are available with pedal kits. Most car racing pedals can be installed using special tape.

Car Clutch Pedal - Located to the left and operated by the left foot (except for automatic transmission), this car pedal is used to change speed gears and controls the transmission shifting for the car.

Car Brake Pedal - Located between the Clutch Pedal and the Accelerator Pedal, operated by the right foot. This pedal is usually wide and elevated well above the car floor. This car pedal is used to engaged the brakes of the car and stops the car when pressed upon.

Car Gas Pedal - Located to the right and is operated by the right foot. This car pedal control the air supply to the car's engine. It is usually narrowad and close to the car floor allowing the driver's heel to rest on the car floor.

STEERING WHEELS
The steering wheel is the part of the steering system that is manipulated by the driver. Steering wheels are the usual location for a button to activate the car's horn. Additionally, many modern automobiles may have other controls, such as crusie control and radio controls built into the steering wheel to minimize the extent to which the driver must take his hands off the wheel.

An undeployed airbag, used to protect the driver in event of a frontal collision, is mounted inside a cover in the center of the steering wheel.

Power steering and power assist steering both give the driver an easier means by which the steering of a car can be accomplished. Modern power steering almost universally relies on a hydraulic system. Mechanical power steering systems have been invented, but their weight and complexity negate the benefits that they provide.

A stock car audio system refers to exactly what was specified by the manufacturer when the car was built. A custom car audio installation could mean anything from the upgrade of the radio to a full-blown customization of a car based around delivering exceptional sound quality and/or volume from audio equipment.

The most common and familiar piece of audio equipment is the radio / tape player / CD player /DVD Player which is generically described as a Head unit , which also can be called a deck , after older tape-decks. It is also the most likely component to be upgraded with an after market item. A recent development in head unit technology has been the addition of CD players with MP3 , WMA , AAC , and USB support.

Many cars include at least a CD player some have the option for a CD changer which holds multiple disks either in the head unit itself or in a separate unit usually located in a trunk or console. Our horizons have been broadend even further-even newer technology is the addition of DVD players. The position of the LCD screen differs for different DVD players - certain DVD players require the screen to be mounted on the roof of the car (just above the front windscreen), while others require the screen to be attached to the back of the headrests of the front seats and some DVD players have the screens come out of the head unit.

Speakers are generally located in doors and rear parcel shelves of a sedan in modern cars. High end or competition stereo systems often have speakers mounted in "kick panel" enclosures, allowing for larger drivers and better driver placement. Before stereo radio was introduced, the most common speaker location was in the middle of the dashboard pointing through perforations towards the front windshield .

High-end audio systems include Component Speakers that consist of a matched tweeter (small, high frequency), midrange (medium, medium frequency) and woofer (large, low frequency) set. These component pairs are available in two speaker and three speaker combinations, and include an audio crossover which limits the frequency range that each component speaker must handle. This allows each cone to produce its optimal frequency for maximum sound quality and volume. In addition subwoofer(s) are provided for bass and sub bass(ultra low frequency), which is felt, rather than heard. Crossover systems can be active or passive crossover networks. Active electronic crossovers divide the signals before they are sent to the amplifiers giving a dedicated amplifier channel to each individual driver in the component system. Passive crossover networks divide the signal after amplification, making it possible to run multiple speaker component sets using just one channel.

Amplifiers provide the necessary music power, measured in watts to drive the speakers. High Power amplifiers require a large gauge cable to provide adequate voltage and current to the amplifier. The amplifier is a very important component of a loud speaker system. Don't connect too many speakers to the head unit alone. Make sure that the total power handling capacity of the speakers connected to the amplifier or head unit is greater than or equal to the power of the amplifier or head unit.

Sound deadening is often used in the door cavities and boot/trunk area to provide less rattling of the metal in the car, especially the boot/trunk, and to help produce a cleaner sound by absorbing instead of reflecting sound waves. It is a rubber or asphalt-like substance that can be sprayed on or glued on in sheets.

Alternators may be upgraded from the stock unit to increase the current capability of the vehicle's electrical system, often required of high-power audio system components. An additional Deep Cycle battery (or, for very large systems, banks of batteries) can be deployed (often charged via a Split charge relay) to limit voltage drop and allow the system to be played for long periods without the vehicle's engine being run. Installing a capacitor is another option when trying to provide substancial power to the audio system.

* Racing on the street is illegal in almost all places.
* A lot of insurance companies consider performance mods as a liability. Expect more expensive charges or them dropping you.
* Turbo charging a vehicle isn't as simple as bolting on a kit. Along with the complexity of installing it there's the risk factor in damaging valves, heads, pistons, manifolds or even totally blowing your motor and cracking the block.
* All work should be done under the supervision of a professional or if possible, by a professional.
* Buy a Radar detector if legal. This is illegal in the Netherlands, many European countries, parts of Canada and elsewhere.
* Do not treat one item as more important than the other. In other words, do not go out and buy every tool in the shop and then realize you needed metric instead of SAE or vice versa.
* Adding Nitrous to your vehicle is dangerous. You can destroy your motor running large shots. Start conservatively, reinforce your motor, and slowly dial up the shot until your running the amount you want. This will prevent you from blowing your pistons 10 feet under.

And what are u must need before want to start all this??
