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?
