I think the vacuum method could work pretty darned slick, particularly if the there was a spring opposing the vacuum line... engine off, no vacuum, door opens wide open, engine starts, vacuum pulls the door shut. Spring is adjusted for part open at 15-12"hg, and is wide open at say 7", which would be plenty safe. Your vacuum may vary!!

If you're thinking of mounting vacuum actuators inside the lower shrouds, it may be hard to find any that can take the heat. But a cooler area might be to mount a commonly available actuator to the topside of the door boxes with a short rod going down to a lever on the outside of the door ?

If trying the vacuum actuator technique, they should be on the outside somewhere, both to survive the heat better and also to keep the actuation consistent... a hot actuator and its spring wont respond the same way as when cold. Might end up working better and be more reliable to simply use "wax motors", as these are common, well tested and are very reliable, and don't need a computer. I'm thinking about trying out the wax motor method for driving hinged summer winter plates. Right now I have them off, and the warm up is excellent, and the heads get to the nearly the same temps I see in the summer time, and definitely seems to go into closed loop quicker.
