Just wondering if an aneroid barometer is sensitive enough to register airspeed pressure changes from a pitot tube. You'd either seal the barometer casing and lead the tube in through a hole or put it in a sealed perspex box. You'd probably need to zero it every day/trip though and it would be altitude sensitive... unless you unsealed the bellows/diaphragm thing.
I remember making a simple barometer with a big tin can, a rubber membrane and a straw. Membrane deflects, straw amplifies movement...
I guess MAP sensors aren't gonna be near sensitive enough, you'd be looking for readings across less than about 5% of their range.

The gangs took over the highways, ready to wage war for a tank of juice
