272-Degree Camshaft for M20 Engine

The Schrick 272-deg Camshaft is a performance upgrade for the M20 engine, specifically designed for models like the E30 325i and E34 525i (89-90). As the mildest option in Schrick's M20 catalog, it provides a noticeable performance enhancement, particularly in the mid-range, without sacrificing bottom-end torque or significantly altering the stock idle quality. This camshaft boasts a duration of 272 degrees for both intake and exhaust lobes, with an intake and exhaust valve lift of 11.0mm. It includes a valve lift at Top Dead Center (TDC) of 1.6mm. The valve timing is set at 25-67 for intake and 67-25 for exhaust. The material specified is chilled cast iron, known for its wear resistance. Installation requires a valve clearance of 0.25mm for both intake and exhaust valves. Schrick recommends using their valve springs and other hardware for optimal performance and reliability. While new valve springs are not strictly required, it is crucial to ensure that the new valve lift does not fully compress the existing springs; shimming the spring's installed height may be necessary. Tuning is recommended to optimize air/fuel flow for the camshaft's specifications. The company provides a one-year warranty on their camshafts.
