Cat Cams Camshaft 275°/259° – Porsche Flat-6 12V SOHC

Description

Cat Cams Camshaft 275°/259° – Porsche Flat-6 12V SOHC is a performance camshaft profile from Cat Cams, developed for the Porsche Flat-6 12V SOHC engine. Cat Cams has built valvetrain components in Belgium for decades, and every profile is ground to motorsport tolerances rather than adapted from a generic blank.

Key Features:

• 275°/259° duration: an intake and exhaust profile matched as a pair, so the engine gains area under the curve without losing driveability.
• 11.45mm intake / 10.00mm exhaust valve lift: increased lift flows more air through the existing head without requiring further machining.
• Correct valvetrain match: ground specifically for the flat 6, air-cooled SOHC 12v configuration, so it drops into the standard head.
• Made to order: ground to spec by Cat Cams in Belgium, so the profile arrives fresh rather than off a shelf.

Fitment:

• Porsche Flat-6 12V SOHC
• flat 6, air-cooled SOHC 12v valvetrain

Camshaft changes of this size normally want matched valve springs and a revised tune to realise the profile fully — talk to us if you want the supporting parts specified alongside it.
