Cat Cams Camshaft 298°/283° – Porsche 4cyl 2.5L 8V SOHC

Description

Cat Cams Camshaft 298°/283° – Porsche 4cyl 2.5L 8V SOHC is a performance camshaft profile from Cat Cams, developed for the Porsche 4cyl 2.5L 8V 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:

• 298°/283° duration: an intake and exhaust profile matched as a pair, so the engine gains area under the curve without losing driveability.
• 12.50mm intake / 11.55mm exhaust valve lift: increased lift flows more air through the existing head without requiring further machining.
• Billet steel construction: machined from solid billet steel for maximum strength, holding its profile under sustained high-rpm loading.
• Correct valvetrain match: ground specifically for the straight 4, water-cooled SOHC 8v 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 4cyl 2.5L 8V SOHC
• 944 (also 924S from 1986)
• straight 4, water-cooled SOHC 8v 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.
