Guess no-one knows? The CarFolio has the basic specifications of the engine and car though. Looks like it has a 90hp engine 1582cc's and the 1965 model years had the Solex 40 P11-4 Carburetors. Which according to another Samba thread have a air flow of 232.6 cfm with the stock venturi 32mm size but with the 37.5 venturi the carb flows 253 cfm/barrel. (@ 10") (X 1.673=28")
Does anyone have the formula to figure the Head CFM based on other info.?
