Electronic Fuel Injected engines have very different camshaft requirements from those of carbureted engines, which require a strong signal at the carb booster to draw the correct fuel mixture into the combustion chamber. Since that excess flow is not required with EFI engines, camshaft lobe profiles can be manipulated for increased performance.
The new COMP XFI Camshafts feature wider lobe separation for decreased overlap, yielding a more efficient combustion process. COMP XFI Camshafts lobe profiles were designed to work in conjunction with recent valve train technology advancements such as COMP Cams Super Clean Beehive valve springs, thus delivering faster valve openings and closings while maintaining complete valve train control. Additionally, the COMP XFI Camshafts take advantage of the high velocity EFI-style cylinder head intake ports, intake manifolds and combustion chamber designs.The result: dramatic improvement in performance and durability for today’s fuel injected engines.
