Do they remain open once running?
What popped into my head was make the butterflies mechanical and sync with the carb butterflies and poke it through the hood like a Mini blower...

I have no idea about your vacuum set up or what the it takes to operate those.
last thing I'd think you want is them closing while your driving.
As I stated worse case convert it a mechanical setup.... then the opening and closing will match your carb and pedal...

It's an air filter it doesn't 'do' anything. Well other than filter the air I guess. You have an air filter complete with cold air inlet from the high pressure area in front of the rad.. Where are you going to connect the valve cover hose to it?

Mike, it's just a Sacratomatotown thing.7twentyguy, that breather would look REALLY COOL popped outta your hood.
Just my $.02

Even if the butterflies open as they should, the air filter inside is tinny, and if anything will make less power.
I'm with Mike, glue it to the hood, maybe glue 4 of them to your hood, and look really trashy.

I don't see how engine vacuum will hold the butterflies open. Engine vacuum is highest at idle and slowing down. When the engine is floored there is very low vacuum. Basically it will open when idling and close when floored. Must be spring loaded holding it open and use vacuum to close it.
I looked this thing up and there was a whole page of complaints about getting it to work (on a bike).... problems driving in the rain..... Wow $300 for this??? I'm in the wrong business.

I've actually tested air cleaners for Kuryakyn on my flow bench. Their designs are mostly well thought out and flow air VERY well. But any time you add a throttle plate to an air cleaner, you have several factors that can and eventually will impede proper flow. Even if the air cleaner's throttle plate is tied directly to the carb's throttle plate, you disturb the air entering the filter. If the throttle plate was switched to open and STAY open when the key is on, then you may have a solution?

Like top fuel dragsters, throttle plates are on the air cleaner to keep things out of it when the engine is not running. Theirs are directly attached to the real throttles, but typically on a cam that opens the vent blades at a rate faster than the carb blades. Tricky, eh? Don't ever let the intake choke the carbs, or disrupt the straight flow of clean air.
