Improve control performance can be said to be a foreshadowing of the power system, has a strong control performance coupled with the enhanced power system that can play a complementary effect, Fox has two different power units, which are 1.8L and 2.0 two version, two different people have the power conversion unit. In the conversion of these two machines, they also have different orientations, some choose to strengthen the NA engine, but also have a choice of plug-turbine, the corresponding modification of two different routines, the business has launched a modified parts are also different, as for everyone here a brief review. The first is the intake system, engine intake system modification is to enhance the strength of the basic steps of the engine, either NA or turbo engines, power to make the vehicle can be improved, modified intake is very necessary, like people, to run fast, naturally aspirated volume to increase, which can meet the needs.
WR produced wind cups, NA friends for playing the most intense modification is to be converted into four jets direct injection engine style, because that
Samples aspirated engine allows more direct, but the wind was Germany's role is back scattered air,ignition coil, let orderly sucked into the cylinder.
Original bit high flow air from Taiwan STOCK compartment with bellows or mushroom intake
Modification has a great respectively, original style bit more attention to the torque output of the engine.
Of course, after the inlet to the exhaust, intake and exhaust system, is one of the most basic step of modification of the vehicle, the choice of the exhaust gas can be divided into two types, corresponding to different orientations, and if some of the horsepower requirement may be selected straight-through exhaust system, while the torque demand can choose something with a back pressure of the exhaust system, in fact, there is a contradiction between the two, straight-through exhaust vent allows more smoothly, to the engine high rpm exhaust gas needed as soon as possible with a good help, but unable to play due to back pressure effect, ignition Coil Pack, so we will have a certain weakening of torque at low rpm, on the contrary, with the exhaust back pressure design, the engine is low rpm, back pressure due to the design, so that a greater vacuum force, can automatically sucked in the engine exhaust gas, but a high-rpm, the exhaust speed, what is needed is an exhaust gas discharged quickly to the outside, so that , back pressure design will play a lot of resistance, which play on the horsepower of a certain weakening. Of course, there are relatively weaken the right.
After replacing the intake, exhaust after, went to the inside to strengthen the engine, and the corresponding modification of different ideas, there are different modifications to choose the direction and strengthen NA engine and plug-turbo engine has a different choice from the compression ratio, the strengthening NA is required to increase the engine compression ratio, to improve the efficiency of the explosion, and the plug of the turbine engine, it is necessary to reduce the compression ratio,bmw turbo, so the knocking phenomenon. Increasing the compression ratio of a variety of methods, the most direct way is to change the piston and the cylinder head gasket, replaced the convex top of the piston, can effectively increase the compression ratio, and replaced the concave top of the piston to reduce the compression ratio.
The convex top of the piston effect is to enhance the compression ratio of course, enhanced when the pistons used in NA, increases the compression ratio, can increase the
The intensity of the explosion, however, increased compression ratio, the corresponding natural octane oil also increased, so as to prevent the occurrence of knocking.
