it is quite a trick to dump the velocity head with a small volume,
look at the small res of Swiftech designed for the DDC

the problem with bb's 'design' is that it will not work
he should have built a prototype before posting and answered his own question
no points for anything if too lazy to prototype, a dwg is not a design
some plastic and a tube of goop reveals all (or google !)

if one wishes credit as a designer, put out some effort
