Car tuning engine transformation Revealed

Specially adapted vehicles only within the specified range of competitive private, public security departments approved without modification of vehicles onto the streets is illegal （saab turbo）.

According to regulations, the appearance of the body must be checked when the vehicle inspection, bumpers, mirrors, and other components under endoscopy are complete, intact; window glass is intact; whether the body Zhou Zheng; rear overhang meets the requirements; Compartment there no change, fixed is reliable.

Now has 50000-150000 private car owners as the main modification groups, major institutions may change can be divided into body rigidity, engine power, transmission gear dense than several parts suspension, brakes, electronic control units, etc. these components act in harmony among each other, if there is any one to make changes, will directly affect the driving experience.

Engine for the car just as the heart for the people, the whole car the most important part in this. Although the power output of an engine can be upgraded in many ways, such as changing the air-fuel ratio, forged pistons expand and strengthen connecting rod, crankshaft change, change spark plugs and so on. But the process is basically converted into improved exhaust change the ignition system （saab turbocharger）.

Intake System

On the engine air filter is to filter the air needed for the engine is running, the gasoline engine has this device, playing car people, the original car's air filter installed seems inadequate intake air too. So people play car modified intake system (commonly known as mushrooms) practice. Modified products are made using special chemical fibers, its biggest advantage is that the air filter while the net to make the air flow into the combustion chamber, the flow rate increase, so that the fuel burn more fully, more efficient units, engine performance naturally different.

Exhaust System

After acting engine will exhaust gases, exhaust efficiency is directly related to engine performance merits. The increase in the intake, combustion, while intact, should also enhance the exhaust efficiency. Now more than replaced by straight row, that changed the exhaust system, front, remove the muffler and other purification devices, will exhaust the whole process shortened exhaust gas through a simple process that, after the car accelerated improvement will be more rapid. Straight row in the modified barrel will be deafening noise when accelerating release, but a total shock should not be too large, otherwise it will exacerbate a sense of fatigue and irritability driver driving the vehicle for a long time.

Ignition System

Ignition system together constitute the spark plugs and ignition, original car harness configurations are single group, by sex and by the amount of voltage and current are not satisfactory. The spark plug of a wide range of materials are nickel, platinum, iridium alloy points, form a single, double, the difference between the quadriceps, as well as high temperature, low temperature difference between the heat-resistant properties. The spark plug may be selected based on the compression ratio of the engine speed and air-fuel ratio. High compression ratio of the engine requires the use of high temperature spark plug; conversely, have corresponding low temperature resistance, low compression ratio spark plug engine to use some of them. Ordinary spark plug temperature resistant 6-7 degrees. Modified vehicles because power upgrade, it also needs to improve a little spark plug temperature, generally use 7 degrees spark plug factory, after modification should improve once the use of 6 degrees spark plugs. If you replace the spark plug wires and spark plugs, engine performance real-time change, throttle hard, start fast.

People who like to play cars, are generally looking strong enough car speed, braking distance is short enough, but generally the original car is mostly done in this regard moderation, can not meet the needs of people play car, it is necessary to change the complete dynamic brake talk about change a （Subaru turbo）.
