I dont want to shoot down your idea at all...but I am compelled to play devils advocate here and point out the issues that pop into my mind in regards to that idea...so heres my constructive criticism...
the flapper would be required to flap back and forth for each side pretty damn fast in order to properly accomplish this task. this means you have to have some sort of mount for the axle which not only will be required to be as free as possible but also maintain its alignment overtime. because its also in a area which you are guaranteed to see massive amounts of heat, the material used will need to be able to withstand that type of duty. it will also probably have to be a certain weight so that it can "flap" at a speed which can keep up with the pulses. finally because its a moving part its another potential thing which could fail and while flapping you would probably hear a "flappity" noise which might turn some people off.

your right...this thread was about superchargers and its digressed into a possible heat issue on the housing caused by FI...
i personally blame the time...and the drugs...

Like I said its an idea. They have wastegates that can handle the heat so im sure with some R&D it can be done, I dont think youd here it at all. I came to me when I pulled that seporator out of the display block I was working on, hell if you can increase the flow through that por 25 to 50%, you have made a big difference, who nows.

My peak and average EGTs are more or less the same between the GReddy manifold/turbo and the much bigger T3/tubular manifold that I'm running now.
I don't think that high-RPM "choking" is pushing the temps up in the ports.
I'd like to see EGTs from a stock motor with the probe in the same location.

you are killing me.. i am you are thinking so way outside the box.. with meds..

that location would be?

Again in my mind...its a design flaw but acceptable considering what they were shooting for. I would have preferred that the rotor chambers be separated from each other and perhaps offset so that you would have two equal sized ports on both sides of the chamber with 4 independant pipes...altho that might have created a heating issue...which may also be the real reason they decided to use a smaller "shared" port to limit the amount of heat between chambers...

LOL, outside the box is a cause for inovation, think of the motor in your car, Wankle wasnt even in the boxes zipcode.

In regards to your idea...perhaps instead of flapping back and forth...you take a flat metal "flap" and install it vertically on a pin running thru the center so it moves horizontally...as the pulse comes into the port...the pressure blows the plate to the opposing port and effectively seals it...when the opposing port fires its pressure blows the flap the opposite direction...as long as your flap was large enough to completely cover the port...could withstand the heat...and was thin enough to give you the maximum volume AND retain enough structural integrity to not warp under the back-forth slamming...its wacky enough that it might work...perhaps shorten center pin so it doesnt actually make contact...or just bearly makes contact...and keep it long enough to prevent the pulse from going "around" the plate...

You got the idea, you just explained it better. Im goint to play with it, I wouldnt try it with a turbo for odvoise reasons. You explained it very well, make the hinge sloppy and I dont think there will be any problems.

The opening due to the angle at 45 degrees inbound would limit how much volume you could get into the port and so it would become your chokepoint. If you remove that dynamic and simply allow the entire plate to move to the opposing side, your restriction would be the volume of the port avail (port-flap width) and how much volume you have due to the port size from the chamber inbound.

Its times like these where I am reminded how much it sucks to not have a machine shop at my disposal. One of these days I'll get around to building a stirling cryocooler and attach it to an intercooler...bring on the heat!! as you add heat the pump gets progressively cooler as it works muuhaa haaa...
