Dual quads versus big hammer!!!...

Don't confuse a bog with being choked out. And they do not operate the same.

One uses Venturi vacuum to pull the secondary throttle blades open.

The other one mechanically opens the secondary throttle blades. Nothing vacuum about that. The air valve is opened from air flow. Not the butterflies.

Two different systems.
It is the same system as the Carter AVS, the AVS was an upgrade to the bog prone AFB.
Open the door too fast on an AVS and it will cause a bog.
