Lightweight, compact and highly tuneable, Ford’s first ‘world’ engine, the I4 Duratec, has already found plenty of fans in both 2.0 and 2.3-litre formats.
Pleasingly the I4 Duratec responds very well to cam swaps, partly because the Mazda designed engine enjoys large ports and valves compared to most modern engines. And it’s this tendency that Belgian based Cat Cams can exploit for those seeking extra power and torque from their I4 Duratec engine for rally, rally cross and race applications, with its new range of motorsport profiles.
Cat Cams has pioneered the use of high lift / short duration profiles, enabling engines to produce an unmatchable spread of torque with excellent power characteristics, whatever the discipline. Indeed such is Cat Cams success with motorsport I4 Duratec profiles, they are used in Marcus Gronholm’s fearsome turbocharged European Rallycross Fiesta ST, which develops 552 horsepower and 600lb.ft of torque!
