I've tried this principle (in my Jeep), with the engine off (at the key), openning the throttle to WOT, and all I get is massive engine braking (along with a roaring sound!). I think more air being sucked into the engine means more pumping losses. I know my Fiat with no throttle plate has zero engine braking though.
What's going on?
