PORSCHE 911 ENGINE HISTORY & DEVELOPMENT (Aichele 1999)

Large hardback tracing the many and various versions of the 911 engine in all capacities and states of tune, turbocharged or not.  205 large landscape format pages and lots of illustrations. Good book but a little slack in the binding suggesting much re-reading of the contents...which shows it has value as a reference work for the enthusiast. Jacket a little rough along the top edge from shelving.
