If there's an elusive animal in the amateur performance world, then degreeing a cam is it. Few know how to do it, and even fewer understand the benefits. If you're following our 347 build from the ...

Variable valve timing isn’t necessarily a new idea, but it is new to BMW motorcycles. With a freshly designed 1,254 cc two-cylinder flat engine, VVT is arriving in BMW bikes for the first time with an ...

Eventually this trickled down to GM's incorporation of this technology into the Gen IV 6.2L L92 Escalade motor for the 2007 model year. GM's design placed a cam phaser on the face of the cam, which ...

A flexible concept for fully continuous variable cam timing (VCT) is presented. The system has been introduced in volume production for both intake and exhaust phasing applications. This paper ...
