"Sometimes, when money and time are irrelevant, great art emerges without the limitations of real life putting a stop to it. And with luck, a book like Ryan Snodgrass' Magnum Opus on the subject 911 Turbo from it."

— Porsche Fahrer Magazine

“‘Exhaustive’ doesn’t even begin to describe Ryan Snodgrass or his opus on the Porsche 930 Turbo 3.0. … This level of detail is emblematic of Snodgrass’ work. … It’s an instant classic in the category of single-model history and detail.”

— Mark Wiggington, Sports Car Market

“…when Snodgrass set out to relate the planning, engineering, styling, and development history of the Type 930, he used his own work [Carrera 2.7] as his benchmark. Then he reset it a great deal higher with his latest book Turbo 3.0. This work – throughout – tends to humble the word ‘encyclopedic’ as Snodgrass explores every element of turbocharging and the turbocharged Porsche 911 in detailed photos, diagrams, and documents.” 

— Randy Leffingwell, RS Magazine

“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.”

— Mark Wiggington, Sports Car Market

“It is as if it’s 1975 all over again, with a twist Snodgrass’s mammoth book has taken something familiar and made it an original, much as Porsche did when it transformed the 911 into the 930. As a reference book, the roots are permanent. As a time machine it’s a bargain.”

— Kerry Morse, 000 Magazine

"Before reading Carrera 2.7, I had always considered the model to be a tiny aspect of the Porsche 911 story, a stop gap model that bridged the gap between the iconic 2.7RS and the start of the EFI 3.0 and 3.2 litre cars. While that may be one way to consider the model, Ryan Snodgrass’ comprehensive book shows just how pivotal the ‘Euro Carrera’ 2.7 model was, both in the influence over subsequent models and the effect on the 930." 

— Historic Racer

“Although primarily focused on the MFI-equipped 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.”

— Classic Porsche magazine

“Detailed part photos turn this book into an ultimate restoration guide as well as encyclopedic buyer’s reference”

— Road Scholars magazine

“If there were valet parking for books, [the Turbo 3.0 book] is one of those confections that would be left right out front, for all to salivate about.”

— Sabu Advani, speedreaders.info

“[Turbo 3.0], the second book by Parabolica Press, can excite without exception and starts where the story of the Carrera 2.7 ended. Thus, the title is a logical successor and raises the quality of implementation to a barely conceivable level. …a more comprehensive representation of a model is hardly possible. … A complete Porsche library cannot be without any of these books, in which the important milestones of the still early Porsche 911 era are documented in detail.”
