anyone ever built a nozzle with an adjustable diameter outlet?

High roller was talking about this some time ago
I'm working on an idea...not sure, though, if it's worth the effort AFA what gains would be seen. That's the first thing to try and figure out.
I the gains could be substantial based upon testing i did at the track with four different inserts in back to back passes.
can't wrap my head around how to build it effectively though.
I think place diverter already makes one.

I already have an idea, I just don't know how to make it look "cool"

forget cool. start with ugly and successful and worry about cool later. lets here the idea. got a drawing you dont mind making public?
There was a prototype in Hot Boat mag about 10 or 12 yrs ago.
It had an adjustable nozzle ID within a small range and you could hydraulically adjust the vertical height also without changing the angle.
There was a lot of hyd. lines and linkages to it.
It was pretty high tech looking and that's gotta be worth a couple mph right there.
As I recall the nozzle looked somewhat like a jet engine nozzle.
I'll do some searching in the magazine pile.
