Cussons P7305 and P73 10 Port Flow Rigs are designed to enable the flow testing of reciprocating piston engine cylinder head ports. These units may be easily configured to provide either a suction flow downwards through an inlet port to simulate the operation of a naturally aspirated engine, or by interchanging two pipes and attaching a flexible tube to the cylinder head intake manifold, to provide a pressure flow downwards through the inlet port to simulate a supercharged or turbocharged engine. The P7305 Port Flow Rig is intended for use with light duty port models with a nominal free air capacity of 50 litres/second, whilst the P7310 unit is more appropriate for heavy duty port models with a nominal free air capacity of 200 litres/second. Either unit may be used with port models or with engine cylinder heads.
