610 HORSEPOWER TWIN-TURBO FERRARI 348 CHALLENGE
The Ferrari 348 Challenge was just not that popular. Even when it was new, other products from the prancing horse just outclassed the 348 in both performance and appeal. Stacey Slead solved this issue by teaming up with Steve Maxwell of Maxwell’s Exotic Car service in California, together they took #10 of just 32 that were made that year and transformed the 355 Challenge into a 3.4-liter V8 twin-turbo capable of delivering 610 horsepower! Maxwell also fitted the 355 Challenge with a six-speed gearbox taken from a 355 Challenge.
