Unlike many competitors who machine their lobes from cast steel, CATCAMS cuts its camshafts directly from billet, which makes them far more durable. CATCAMS camshafts are usually hollow in order to reduce their mass.
CATCAMS' expertise in camshafts and their accessories (valve springs, mechanical cam followers, vernier cam pulley...) has been recognised worldwide for several years thanks to its know-how and its precise study of engines and applications. Each camshaft profile has indeed been developed according to the specifics of each engine, but also according to the intended use (road, sport, rally, drag runs, circuit racing...).
Two parameters matter when choosing a camshaft profile: valve lift and angle (opening duration). Longer opening times bring an increase in power and torque, while greater lift optimises power at high rpm.
