Yes, I thought it provided some good information that I had not seen anyplace else about bell mouths - didn't realize there was so much to them. But, I guess on the racing side 1.5HP can make that 1/1000 of a second difference in winning.

I know some of you have intake designs that involve bellmouths.  I happened to run across his article on bellmouths from a racing car perspective.  Makes some interesting reading - about the relative differences between different shapes.

Ed, it has taken me a few days to get through this 4-page article, but it was worth it.  Very informative, and it's nice to occasionally read well written prose that expects more than a 6th grade reading level.
