Hi = Bob,

I don=92t remember how = many hundred hours I have in this =96 but it was a lot. You need a lot = of passion to go there especially since you have a flying airplane = already.
 
If you look for the most economical and quick = solution I probably would go to Aerochia =96 I think they have a = complete cowl-plenum- design that they sell.
 
If you really want to do = this by yourself you are welcome to stop at 5G7 any time and look at my = design to collect further ideas.
 
 
Tom, I looked = at your plenum page
A lot is possible.  Could be gear actuator, could be = a door actuator, could be the dump valve, = etc.
