In the modified car exhaust systems, the most important part of the banana head should be, because eighty percent of the original header are a lot of open-cast iron products, do not say rough wall, the length of each exhaust manifold is not the same, plus engage, the distance, the shape of the same thorough enough, so it is prone to the phenomenon of the exhaust gas interference, so that conflicting each cylinder block and the exhaust gas discharged: in particular, here and closest to the cylinder head,mitsubishi turbocharger conceivable for intake, combustion of how detrimental a.
Modified banana is the first segment of equal length, that is consistent with the length of the exhaust manifold, which is called as long as the head of banana banana head of the exhaust. Usually produced by automobile works 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, poor implementation stepless weld grinding and try to ease the corner thereby reducing drag and accelerate airflow. Then they will try to unify the manifold length, the emphasis of course is totally committed to equal length, let the exhaust pulse consistent and complete elimination of all the manifold pressure difference, so that is not only conducive to the posterior segment row trachea back pressure setting, the overall efficiency of the intake and exhaust 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, guided by banana head exhaust gas-driven turbine blades, as long as the advantage of the turbine blades can subjected to quantitative, smooth and sustained impact, this supercharged boundaries, efficiency, stability will be improved, especially at high boost set is even more evident. Isometric addition, the total length of the manifold (with turbo head DOWN PIPE batch),nissan turbocharger also need to consider where turbo head when banana production, in general, the shorter the length of the manifold, then, TURBO operation of the reaction will follow accelerated, but relatively long follow-up of the flow is not as good as the manifold saturation, but this is still depending on engine displacement and turbine capacity may be.
