Schrick exhaust camshaft for BMW S85 engine
Highest demands, highest performanceWe are not the only ones who place facts like unrestricted performance, the highest demands and precision on our products in the Performance Line. Renowned tuners and motor sport teams have appreciated this for years. With the Schrick performance camshafts, we have a range of products created to give the tuner and motor sport enthusiast the opportunity to have a wide selection of different camshafts to draw on for current vehicles. Thus, there is an ideal Schrick solution for each engine.
Over decades of development, optimised structural profiles (perpendicular to the running direction) have been developed at Schrick. The so-called 3D lobes with spherical character increase the stability of the camshafts with their optimised structural behaviour and the promotion of lubrication film formation. For this reason, our camshafts easily measure up in highly stressed engines. Positive side effect: friction is minimised!
Profile precision in μ-range (1/1000 mm) as is only possible in Formula 1. Each cam profile manufactured by Schrick is the same. This not only ensures smooth running but also guarantees reproducibility in the engine construction for experienced engine builders and tuners. We ensure this through integrated precision metrology in the process.
Top Surface is, what we call the process combination for the finest conditioning of bearing and running surfaces which has been developed and coordinated at Schrick. The procedure was developed in order to minimise the friction losses significantly. Because only the power at the crankshaft counts at the end of the day!
