Sure, understand the head shake, I am not 'going for' anything in
particular and your comment is of interest, all I am saying is
that "...from a control systems perspective..." etc. I have seen one
or more draw through systems - no probs, will think on it, right
now I have a messy wastegate setup on my factory turbo which I might
be able to concieve of differently if fly-by-wire hardware were
available on my engine. Wasting exhaust implies a 'waste' and is
not congruent with control systems issues of which variable is
controlled and when...
