i didn't see any details or notes about instructions
on how to use or FlowTest the Plates ??
are you supposed to FlowTest the plate
directly bolted to the surface of FlowBench ?
is there a Hole diameter size spec
that the FlowBench must have ?
or has anyone tested the Flow CFM differences
between bolting the plate
directly to the Bench's surface over the Hole
-VS- bolting ontop the hole in a Bore Flow Fixture thats
bolted over the FlowBenches hole.
you'll get different Flow numbers sometimes.
in other words, if i bolt the Orifice Calibration Plate
that came with SF-600 directly ontop hole,
on the machined surface,
the Orifice then has CD=.61911
and flows so much air cfm at 25"
if i then bolt a Cylinder Head Fixture on the FlowBench's
machined surface directly centered over the SF-600 hole,
and FlowTest with that same Plate ontop of a
Head Fixture's hole..it makes a difference?
example=>
the Head Fixture's Bore diameter at 4.000" inches
and about 4.000" or so inches in height,
seems to influence that Flow thru distance
then maybe in combination with the 4.000 dia step
to the 5.000" dia SF-600's hole,
then the 5.000" dia step to the Bench's plenum cavity,
makes a small difference.
