Length exhaust headers and other car modification of banana dictionary

In the modified car exhaust systems, modifications parts the most important part to be banana head, because eighty percent of the original header are a large number of open-cast iron products, do not say rough wall, the length of each of the exhaust manifold is not the same, plus engage, the distance, the shape of the same thorough enough, so it is easy to produce the phenomenon of the exhaust gas interference, so that the conflict and the exhaust gas of each cylinder block: in particular, here and closest to the cylinder head, Understandably for intake, combustion of how detrimental a.

    Modified banana that as long as the header, that is consistent with the length of the exhaust manifold, so that the head of the banana is called as long as the exhaust head plantains. Normally produced by the car tuning banana head, the vast majority will use the inner wall of smooth stainless steel, stress modified depot is still connected to the manifold base and then angle the site, the implementation difference stepless weld grinding and try to ease the corners thereby reducing drag, accelerating airflow. Then they will try to unify the manifold length, H-beam Connecting Rods the emphasis, of course, is totally committed to equal length, let the exhaust pulse harmonization and complete elimination of all the manifold pressure difference, so that not only conducive to the posterior segment row trachea back pressure setting, the overall intake and exhaust efficiency can be increased dramatically.
But as long as the first segment of non-NA car (naturally aspirated) is a great tool for TURBO supercharged car is also quite effective, by banana head guide exhaust gas-driven turbine blades, as long as the advantage that the turbine blades can subjected to quantitative, smooth and sustained impact, such boundaries boost efficiency, stability will improve, especially at high boost setting is even more evident. Isometric addition, the total length of the manifold (with connecting rods DOWN PIPE turbine head batch), also turbocharged local considerations required when making banana head, generally, the short length of the manifold, then, TURBO operation of reaction will follow speed up, but not as good as relatively long follow-up flow manifold saturation, but it also still depends on the capacity of the engine displacement of the turbine may be.
