Serious automotive enthusiasts consider Porsche’s Carrera 2.7 RS to be the archetypical 911…and deservedly so. The cars are light, responsive, purposeful and the type 911/83 engine delivers scintillating performance. Over the last 40 years the 2.7 RS has been covered in dozens of books and articles. Yet its successor – a car with the identical engine and similar DNA – remains either unknown or misunderstood even by long-time Porsche enthusiasts. That car is the Carrera 2.7 MFI. This book tells the complete story of these remarkable, unheralded sports cars.
The Carrera 2.7 book has been meticulously researched using the Porsche factory archives, private collections, period documentation and intensive study. The book attempts to cover everything an owner, restorer, historian or enthusiast would want to know about this intriguing 911 variant. Content includes comprehensive discussion of original options, photos of key details, insights into factory production, competition history and a considerable amount of material never before published. Although primarily focused on the top-of-the-line mechanically-fuel injected Carrera 2.7, this book will also prove valuable to enthusiasts of any of the Porsche 911 and 930 Turbo models produced during the mid-1970s.
From 1969 to 1973, Porsche built different versions of induction systems for the varied models delivered to the
American market. For the 911T, 1969 to 1971 models, Porsche used carburetors (Weber and Zenith-Solex). For all the other models in this time period, Porsche used the Bosch mechanical fuel injection pump system. (See Picture #1) Picture #1 This pump is called the Bosch PE pump (See Bosch Technical Instruction Book P/N VDT-UBP 210/1 EN). It is a converted diesel timed fuel injection pump coupled with port injection. The advantage of this FI pump system over carburetors was that this fuel injection system did not have the restricting venturi and venturi intensifier that the carburetors had.
Also where the carburetors had a distance of about 8 inches from the venturi (source of fuel) to the intake valve, the
distance from the port injector to the intake valve on the fuel injection system is about 2 1/2 inches. This port injection makes the
engine extremely responsive since the distance which the emulsified gas has to travel is greatly reduced, thus producing more horsepower at (WOT) full throttle than the carburetor system could deliver. Comments are closed.
