Ferrari 333 SP details the origin and racing history of the Ferrari 333 SP. Uniquely, none of the 333 SP models were entered into races by Ferrari itself. The cars were built specifically for customer use; a purchase price of $900,000 included two spare engines and race technical support supplied by Ferrari engineers.
A total of 40 cars were built; the first four by Ferrari, the remainder manufactured by Dallara & Michellotto using Ferrari engines. All of the cars were sold to, and race entries made by, privateer teams. From 1994, the cars contested the IMSA World Sports Car Championship, the United States Road Racing Championship, and the American Le Mans Series, at circuits throughout North America. In 1997, the cars also featured in the Europe-based International Sports Racing Series, as well as the 24 Hours of Le Mans.
Two years later, the Doran-Lista team installed a Judd V10 engine into its 333 SP, with the aim of increasing power and improving fuel efficiency. In all, from the 126 races entered, 47 victories were claimed by the 333 SP.
