Twin TBI's

[CSH-HQ]

I've done two very different things:
  The easiest, and least distructive was just have some cones made with just 
an almost 0 taper, and then used a file/electric drill/calipers to generate 
a workable taper.
  One other "trick" was drilling out the orfice where the cone seats to that 
while it still the same count open, the cross sectional are is larger.
  The shallow tapered cone was the better of the two for what I was doing.

slow, and needs dampening to control some of the over-run/idle problems.

Merry Christmas, and a Happy New Year, from the staff at CSH, HQ, and the
