Lynn,
A quick question!
The side inlets in the cast end-housings, have a
reducer ( reduction in inlet size) of approx 2mm ( all round) just after the
opening. This reducer ( reduced area) carries through to the housing face
where it changes to the face shape.
Does this reducer act as a choke of the inlet
charge. I've had advice that it doesn't do anything but wonder why it's
there?
