Infinite radius does not have the traditional radiused ring to create the venturi. Instead, the main jet is placed at the smallest diameter of the gradually sweeping radius machined into the throat of the car, it Looks totally smooth.  I really don't think this new Infinite radius design provides a strong and sudden pressure drop as needed to atomize fuel well at low to mid rpm. Just speculation, but I can't see this working well at less than max rpm.  I'll see if i can find a pic or drawing
