The point of diminishing returns is 9x the bore diameter. The only taper
you'd want after this would be to compensate for friction losses over a
distance and I don't think friction's a significant factor unless you're
piping the output several feet.

I use the term Bore to mean the smallest diameter in the tube.

Everything on these inducers is based on the bore diameter.

If the Bore dia.  is 1" (Bd)

The Tube length (Tl) =  Bd x 9

Taper = 1:12

The intake Chamber dia. (Cd) =  Bd x 2 or 3

Chamber length (Cl) = Cd x 2 or 3

Using these ratios the inducer has a bore of 1", a tube 9" long, with a 1
3/4" dia. throat, and an intake chamber 2-3" dia. by 4-6" long.

I used to state what the books say for the jet position but have found by
experiment their positioning doesn't apply to what I can build so I leave it
to the individual to find by experimentation. Same for the jet orifice.
