284-degree Sport Camshaft

The Schrick 284-degree camshaft is a performance upgrade specifically designed for the S14 engine found in the BMW E30 M3. It is typically used on the intake side and is often paired with a 276 exhaust camshaft for optimal performance in street-driven applications. Schrick camshafts are manufactured in Germany from wear-resistant chilled cast iron, utilizing advanced CNC machining for precision. The product comes with a one-year warranty. Specifics for the S14 284 cam include a lobe duration of 284°, valve lift of 11.5mm, and valve timing figures (IO-IC-EO-EC) of 36-68 68-36. Intake valve clearance is 0.25mm, and exhaust valve clearance is 0.30mm. While Schrick does not mandate additional hardware for this cam, they strongly recommend new valve springs, seats, and retainers for optimal performance and longevity. The BMW Motorsport/Evo 3 valve springs are a common recommendation. Proper tuning and potentially valve timing adjustments are crucial to maximize the benefits of this camshaft, as is ensuring the valve lift does not fully compress the spring, which may require shimming the spring's installed height.
