I wondered why they stoped doing the NACA ducts, I thought it might have been money.
A lot isn't always enough! I remember some stories about IMSA racers trying to get cool air to their 911s. Bottom line was they were never able to get enough gain to make it worth while, in fact I believe that they lost power in general through those efforts.
