INTAKE MANIFOLDS Intake manifold conveys the air-fuel mixture to the engine by means of reed valve. The total efficiency of an engine is calculated as the product of various partial efficiencies, such as: volumetric efficiency thermodynamic efficiency mechanical efficiency Volumetric efficiency is the ratio between the quantity of fuel that can enter the combustion chamber and the displacement of the engine. One of the main factors affecting volumetric efficiency is loss due to friction that the fluid encounters (air-fuel mix) when feeding from the air filter to the combustion chamber.…

REED VALVES VL7 These are reed valves designed with flow corner and with calculed capacity section. The petals are made of a material composed of karbonit. They are manufactured with advanced production processes and with the use of raw materials carefully selected, these reed valves are designed for racing engines and they have been tested directly on race tracks. Carbon fibre body and reed valve seat. Petals with thickness 0,30 mm
