It's not closed, you will be losing whatever comes out of the bypass valve and whatever comes out of the motor.

We looked at doing this at one point.  It seems to me that velocity would be
a more a function of tube diameter, which in any event is already partially
"set" by the design of the MAF any way. 

It's a closed system, so you're metering the same "weight" of air
regardless.  Don't know exactly how this would play out vis-à-vis the hot
wire, but my college room mates sailing experiences in comparing Rocky
Mountain winds to Rio de Janeiro racing, suggest that it takes velocity AND
density to move a sail boat, i.e. a low density 40mph Lake Dillon "breeze"
wouldn't flip his Force 5, but a 30mph Rio de Janeiro blow would.

HTH, gotta go wash the dog
