Schrick 288° camshaft is their most popular cam spec for the M20 engine in the E30 325i and E34 525i (89-90). It became really popular for E30 track cars where the added power at high RPM was put to good use. There is a lumpier idle and loss of torque in the low end as the power band is shifted upwards in the RPM. The 288 cam also works with the stock M20 pistons (more aggressive cams will not). For those looking to get more mid-range and not lose as much low end, the 284 is also a popular option.

Camshaft tuning is all about optimizing air/fuel flow for your specific needs. The higher degree will open the valves sooner, deeper into the combustion chamber, and for longer time. Choosing the correct camshaft depends on the rest of your engine specs and goals. More aggressive cams should be paired with appropriate air and fuel upgrades to make full use of their operating specs.

All Schrick camshafts are made in Germany using wear-resistant chilled cast iron and machined with advanced CNC equipment. They have a one year warranty.

Manufacturer's Notes:
1. While new springs may not be required, you must ensure the new valve lift does not fully compress the spring. It may be necessary to shim the spring's installed height.
2. Valve timing and valve opening durations are shown minus the ramps.
3. Valve timing is shown in °Crankshaft in relation to TDC.
4. All valve lift figures are shown without deduction of valve lash, i.e. the actual valve lift is the stated valve lift minus the valve lash. Hydraulic lifters have no lash so the valve lift is the actual valve lift.
5. Lumpy or rough idle is caused by valve overlap (intake and exhaust valves open at the same time). Some of the lumpy idle can be adjusted out with a proper valve adjustment using the new specs. Some roughness may remain, depending on the aggressiveness of the cam.
