I'm not trying to say that it is a true Venturi at all. Just attempting to illustrate how there is a correlation within it's concept that folks try to capitalize on.
In just about all throttle body applications I've seen that claim a horsepower increase, tests show a marginal or even negligible difference in overall power changes - whether it goes up or down. On the Mustang side if the fence, I remember some folks talking about how the BBK throttle bodies increased throttle response. Upon investigation, it appears that the internal gearing of the throttle body was different from stock allowing it to open just a hair faster than normal, giving it it's perceived throttle increase - in conjunction with it's larger diameter. I'm not saying that's the case here but, I suspect that opening up the throttle body just before the butterfly would allow a larger volume of air to collect before being taken into the intake manifold. That in of itself may give a perceived increase of throttle response and even an increase in power so long as all the other variables are in line, too.
I have seen more extreme examples of folks utilizing a Venturi on vehicle applications. It looks awfully impractical and for the effort involved, doesn't substantiate time and effort investment.
