Welcome to PORSCHE 911 Performance, the official site for the ultimate guide in building a high performance street or track 911. This book is the accumulation of six years of testing and developing an early 911S to construct a highly competitive club-level race car.

The good and the bad are here. What worked and what did not. What had to be done over and what is left to do. The book is not the only Porsche book you'll need for your self, but it is an honest account of what it took to create this successful racing 911S.
