“Exhaustive” doesn’t even begin to describe Ryan Snodgrass or his opus on the Porsche 930 3.0 Turbo. Let’s start near the back, on p. 452. Here, along with a handy production-data decoder for the model, is an exhaustive list of EVERY 930 from 1975 to 1977, including paint, interior, engine, gearbox, tires, distributor, de- livery and completion date — plus a synopsis of installed equipment. This level of detail is emblematic of Snodgrass’ work. He is a former software engineer, and his love of Porsches led him to start his writing career with Carrera 2.7, now followed by Turbo 3.0.

It’s a thick, 10.5-pound, beautifully printed, designed and written book on the car that Porsche used to repudiate the awful cars that came out of the mid-1970s, when fuel economy and safety were the highest representation of the art, and performance was an ugly stepchild. Using turbo technology and knowledge gained from racing the 917, the Carrera 3.0 was an antidote to the times.

While only 2,819 of the 3.0 Turbo cars came out of the factory, they had an outsized impact on the market (with prices to match, as a first-year 930 is going for around $150,000). Sometimes called the “doctor killer” for the dangerous intersection of high-horsepower, turbo-lag and a lack of skills behind the wheel, the 930 was actually a touch slower than the mechanically injected 2.7-liter predecessor. But that was mostly down to extra weight that balanced the increased output, mostly thanks to safety equipment (thanks, Ralph Nader!) demanded at the time. Heck, safety was such a top-of-mind item that there were threats to kill all convertibles in that period. So the introduction of the 930 was certainly counterintuitive — and well-received by enthusiasts.

And well-received is what this book should be. It’s an instant classic in the category of single-model history and detail.

Provenance: Ryan Snodgrass brings a software engineer’s hyper-fo- cus and demand for perfection to his second book. Turbo 3.0 is an intense, deep dive into the history of the model and every scrap of information available.

Fit and Finish: This book is simply beautiful. The claimed (I didn’t count them) 1,508 photos and illustrations are beautifully reproduced on quality stock. The overall design is understated and serves the content. The entire package is top-shelf.

Drivability: With Turbo 3.0, Ryan Snodgrass has reset the bar for any future Porsche book. The text is smart, lively and easy to read, supporting an incredible amount of information. At $395 for one of 2,500 copies of this limited-edition tome, you can expect the same appreciation in value as in the car — even as you appreciate Turbo 3.0 as a resource and good read.

Mit dem Turbo erweiterte Porsche sein Produktportfolio im Jahr 1974 nach oben und stand hiermit in direkter Konkurrenz zu Ferrari, Lamborghini und Co.. Das zweite Buch des amerikanischen Verlags Parabolica Press nimmt sich dem Turbo 3.0 an, der nur für einen recht kurzen Zeitraum produziert wurde, ehe er vom Turbo 3.3 nahtlos abgelöst wurde. Abermals erhält man hier ein Prachtband über einen weiteren speziellen Porsche 911.

Das Buch kommt wie der Titel zum Carrera 2.7 in zwei Editionen in den Verkauf, wobei zu Rezension die üppige Publisher’s Edition zur Verfügung gestellt wurde. Diese kostet 599 € statt der 399 € für die Limited Edition, wobei beide Bücher selbstverständlich limitiert sind. Die Limited Edition kommt im klassischen Schuber daher und ist auf 2.500 Exemplar limitiert. Die Ausstattung entspricht somit der Edition vom Carrera 2.7-Buch. Die Publisher’s Edition hingegen kommt in einer sehr aufwendigen Box daher, die beim ersten Begutachten einen gewaltigen Eindruck hinterlassen kann. Lediglich 300 solcher Bücher werden auf den Markt kommen und zeichnen sich auch durch eine Nummerierung und die Signatur des Autors aus. Das Öffnen der Box bringt die das in rot gehaltene Buch zum Vorschein, welches durch ein Band herausgeschoben werden kann. Erst auf den zweiten Blick kann man noch weitere zusätzliche Features entdecken, die sich hinter einem schwarzen Blatt verbergen. In der darunterliegenden Mappe finden sich zahlreiche Archiv-Materialen, die teilweise aus dem Porsche Archiv wieder neu reproduziert wurden. So finden sich neben Pressemitteilungen sogar Dias und Werksfotos wieder. Ein toller Fundus, der einen Einblick in die Archiv-Arbeit ermöglicht. Passend hierzu findet sich in der Publisher’s Edition auch der zweite Teil der Behind the Scenes wieder, in dem auch intensiv die Arbeit nach seltenem Archiv-Material erläutert wieder. Diese 20-seitige Broschüren liegt ebenfalls der Publisher’s Edition bei. Ein durch und durch beeindruckender Auftritt, den das Buch hinlegt.

Following its domination of the Can-Am racing series in 1972 and 1973, Porsche used its experience with turbocharging technology gained in motorsports for serial sports car production. Launched in 1975 with a turbocharged flat-six engine, flared wheel arches to accommodate wider wheels, and unmistakable “whale tail” rear spoiler, the 930 Turbo was revolutionary in its performance. It was the fastest German production car upon its introduction, helping Porsche to fortify its reputation as a seminal sports car manufacturer.

Following in the considerable wake of his award-winning Carrera 2.7, author Ryan Snodgrass again hones in with laser-like focus on just a single variant of the iconic 930 Turbo—the earliest 3.0-liter examples produced from September 1974 through June 1977—tracing the model’s roots and origin during an era that is often referred to as a dark time for performance cars.
