Does anyone know if Porsche uses venturi duct aerodynamics to reduce rear end lift on either the 996 or 997? This technology is used on the Ferrari 360 CS, Ford GT and Carrera GT but I don’t believe that the technology is used on the 911 yet. If not venturi ducts, then is their any other undercarriage aerodynamic effects used on the 911? Assuming that the venturi technology isn’t used, is the rear engine design incompatible with venturi aerodynamics?
I have wondered for years why the Porsche didn’t eliminate the pop up air spoiler and incorporate the spoiler underneath the car or at least supplement the pop up spoiler with an aerodynamic device underneath as well. The only undercarriage aerodynamics that I can recall on any Porsche other than the Carrera GT is the 944 turbo underbody spoiler. Does anyone have any possible explanations or information concerning these issue?
