In spite of all the material published about cams, cam design, applications and the like, our experience at Competition Cams indicates there still exists much mystique concerning cam timing and valve ...

If ever you've had to choose the right camshaft for your engine you understand how tricky it can get. It boils down to knowing what you want the engine to do and how the vehicle will be driven most of ...

If we were to ask for a show of hands, it’s a safe bet to assume many enthusiasts would reluctantly admit that camshaft theory is one of those topics that causes more than a little consternation. You ...

Valve overlap—that crucial interval when both the intake and exhaust valves are open, expressed in degrees of crankshaft rotation—is typically a fixed parameter and always a compromise. For example, ...

Power in numbers-the golden tenet. Everybody's got a little bit of power under the hood, but it's never enough. Unless you can smoke Titan rockets off the line or go through tires faster than a drift ...

When it comes to the many variables of combustion inside an engine, engineers measure the timing of key events in degrees of crankshaft rotation, a relative frame of reference that remains constant ...

Most modern variable valve-timing (VVT) systems use a cam phaser that rotates the position of each cam­shaft relative to the timing chain. Think of making a record turntable go faster or slower by ...
