Intake manifold Ferrari 308 4 V / 328 carburettor

2 piece intake manifold for conversion of 308-4V or 328 engines to IDF44 carburettors or single throttle parts. For DCOE connection available on request. The intake manifold is machined from the solid. The intake duct is manufactured on a 5-axis machine. The duct goes from round to oval and takes into account the axial offset from duct centre cylinder head to duct centre carburettor. At the same time, a linear throttle acceleration is achieved.
This means that the cross-section is reduced linearly to achieve optimum flow results. However, the cross-sections are also not too large in order to still achieve good response in the lower and medium speed range.
With these bridges we achieve up to 420 hp at 8,000 rpm with a very nice torque curve.
