modified intake and exhaust systems of combat Raiders

With the growing car into the average home, Car tuning is also getting closer and closer to us, some owners feel slow engine response, and some owners think whirring noise of the vehicle was interesting （gt1544v turbo）.

These vehicles are involved in the intake and exhaust system modifications. Beijing ABT Han Shide Electronics Company technical director Shi Xiaohui said intake and exhaust system modifications in Europe and America Department and Japanese points.

Case I: after returning from studying British Tsang bought a 1.8L Automatic golf. But he believes speed is not fast enough golf, you want a faster engine response speed, while Tsang did not want to let the engine sound too, want to keep a quiet ride space.

modified proposal: European cars such modified intake and exhaust can choose K & N high flow air filter to increase the intake air. This is also the German cars in general practice primary intake modification. Large selection of original intake air filter intake without the use of mushrooms is relatively safe solution （peugeot 307 turbo）.

When you install just replace the original cartridge can be. ABT original exhaust tail section uses the appropriate row to reduce the discharge pressure. Shi Xiaohui said that such modifications do not need to replace the exhaust pipe and the middle, because Tsang effect of the modified requirements for quite quiet, so the only way to change the end of the row can not affect exhaust emissions and does not produce a large exhaust noise to enhance the response of the engine under the circumstances.

Comments: If full use of ABT German original imported parts, similar to Tsang such modified takes about 8000 yuan. If the German imported parts, but not ABT original pieces, the required conversion costs about 5000 yuan. And if full use of domestic components, the entire modified only 1,000 yuan.

Case two: with an Impreza Wang hopes to further enhance the dynamic performance of the vehicle.

modified proposal: These Japanese cars, the intake system can be used Blitz intake mushrooms and piping to maximize the expansion of the engine intake air. When you install the original air filter box needs to be removed, the mushrooms placed as far away from the engine, well-ventilated location.

And do not forget to remove the air flow meter reinstalled mushrooms pipeline. In the exhaust section, Shi Xiaohui proposal can choose GPSports the tail section combinations. This reduces exhaust pressure, while increasing exhaust patency, bringing deep exhaust noise.

Comment: If the full selection of imported parts, like this modified Wang, probably costs less than 10,000 yuan.

Precautions modified intake and exhaust system

modified intake system

For the primary intake system modified is concerned, is limited to the transformation of the air filter can. Getting modified intake system work is to switch to high-efficiency, high-flow air filter, a common brand on the market have K & N, BMC, ARC and so on.

Mushroom head (commonly known as mushrooms) are a class of variants of the filter, usually with the original inlet pipe connection, or connect with modified intake pipe, which is to cope with the greater amount of suction needed for high engine rpm and design. The engine is not modified or severe automatic car, for the sake of keeping the original car low speed torque, or the use of the original high-flow air filter is more appropriate.

The exhaust system modified

modified exhaust system is the first to focus on the end of rows. It is the largest local exhaust pipe produce internal resistance, constituting roughly tail row has two categories, the first category is the use of cross-partition approach reflected waves caused by lower volume, almost all of the original product used in this way; first II was modified supplies common linear sound-absorbing cotton style. Shi Xiaohui said diaphragms must exhaust the resistance is relatively large, it is better to play a more linear vehicle dynamics. But the end of the row linear wave larger than the partition type. But the big noise and big horsepower or two concepts （peugeot 308 turbo）.
