	Ok, I missed something here.  According to the article at
> http://www.spiritone.com/~eoa/Cars/Flow_Bench/Flow_Bench.htm
	A 2 1/8 hole will flow 255 cfm @ 28 inches of water column.  Now
awhile back someone else posted that the "Rule-of-Thumb" for fuel injection
butterflies, or air-valves, the way to size them is for every square inch of
throttle plate area, you will flow approximately 140 cfm @ 1.5 inches of
water column.  So, a 2 1/8 throttle plate has 3.55 sq. inches of area and is
supposed to flow "about" 500 cfm.  The two same size holes are flowing two
entirely different amounts of air!  Where did I miss the boat?
