750 Brawler vs 650 AVS 2 at the track, right OOTB !

I also agree with Hysteric's post #133. The signal to an annular booster is increased because the booster is physically larger, & is purposely place in the middle of the main venturi to reduce the available through the venturi. The engine generates the airspeed, not the venturi. The venturi merely reacts to it. The air speeds up as it goes through the restricted space in the venturi & this causes a pressure drop in the venturi to pull more fuel.
