maybe a spring loaded flap would work well, full effect up to a certain speed and then gradual bleed off when the spring is overcome? Funny you mentioned this, cuz I was wondering if I should try something like that in my fresh-air baseplate; the new scoop is so freakin' big that it's gonna trap some serious air (second-guessing myself on having gone so much taller than original T/A)
