speedReaders.info Review, March 12, 2010
This review is from: Porsche 917: The undercover story (Hardcover)
There is no shortage of interesting books about this car. What makes this one stand out is that it is written by a former race mechanic who knows every nut and bolt on the car. Wingrove worked as a race engineer for Porsche's de facto works team and official development partner, John Wyer's JWA Gulf Team and his hands-on experience and technical background give unique depth to this book. He covers the whole design and development process, dialing the clock back to 1963 to put the genesis of the 917 into proper context. Considering how much has already been published about the 917 it is remarkable that this book, thanks to support by the Porsche Historical Archive, contains quite a few never before seen engineering documents and photos. The Porsche Museum even made its 917L available for in-depth study. The book reproduces a number of memos and letters, several translated in full, and also many quotes and anecdotes that could only have been gathered by someone who was in the trenches. It does not include the Can-Am cars, i.e. the 1972/73 seasons.
In terms of the 917's inner workings the book tells a fully comprehensive story, leaving no loose ends and adding layers of important detail. The many photos are augmented by specially drawn technical illustrations. On some topics the author goes into quite a bit of technical minutia. A prior understanding of racecar dynamics will make a reader fully recognize Porsche's accomplishments with the 917. Racers and engineers will appreciate the insights given into things such as the routing of oilways, metallurgical considerations, wind tunnel work, or spoiler settings. There are only three topics where actual math is involved: drag coefficients, gear ratios, and kinetic energy in the context of braking. The general-interest reader may roll his eyes at these things but the narrative remains fluid throughout and for those who must it's easy enough to skip ahead a few sentences every now and then.
The person who has never sat in a racecar will get a kick out of the "Cockpit" chapter. It details the location of every switch and gauge, how to get in and out of the car, how the seat and trim would feel to the driver, how he would thread his feet into the bulkhead to reach the pedals, what the angles of view are, etc.--if this book had "scratch and sniff" tabs it'd be like being there! A final chapter, "917 in Competition," explains how data acquisition was done and how race set-ups were arrived at. Appended are the 1969-71 ICM results and very detailed specs for the 1969 and the 1970/71 cars. The index is sufficient but riddled with typos and typesetting glitches.

A great book to have if you're a fan of the awesome 917!, November 26, 2008
This review is from: Porsche 917: The undercover story (Hardcover)
This is a great book about the history of the Porsche 917 race car and it's mechanicals; ( a great companion book to have alongside Peter Morgan's awesome 917 book and Peter Hinsdale's older 917 softbound book ). I liked this book because Mr. Wingrove was actually behind the scenes, in the pits etc working on these cars; so he has an understanding that others may not have while writing a book on these fabulous cars and the engineering side of things. This book takes you through the history of the 917 from the early beginnings of testing on up to 1972; so it covers the early testing in the wind tunnel; different body work; mandated changes from Porsche; memos sent out to car owners about these changes etc. The 917/30 is not in this book if that's what you're looking for. The photos and old porsche archived material are awesome and great resource for reference for a model builder such as myself. You will not be disappointed- trust me!! I got this book for my birthday and love it!!

Everything you ever wanted to know about the 917., December 25, 2008
This review is from: Porsche 917: The undercover story (Hardcover)
The Porsche 917 is arguably the archetypical racing car. It is a lavish engineering extraveganza designed for just one purpose: to win endurance road races, most particularly LeMans.
This is an excellent book about the details and history of the Porsche 917 up to but not including the CanAm cars. There are excellent photos and a very thorough text detailing the construction, design, and evolution of this most remarkable automobile. The photos are extraordinarily complete, showing details of the cars chassis and running gear design and construction. The evolution of the body design is most complete and informative. Those interested in just a cursory examination of this car will find much of the inforamtion to be overload; however I was fascinated from beginning to end.
I have a number of excellent books on the 917 and even so found many new and interesting details. I would recommend this book to those who are interested in the engineering behind the car and especially for those whose hobby is building model cars. The latter will find everything they need or want to replicate this car in scale.
