There is so much going on with internal combustion engines (ICEs) these days, it can give you a headache just reading about them. That's why we do the research for you and then cram it into bite-size ...

This collection of cam-related phenomena is intended to take you beyond the degree-it-in and set-the-valve-lash plateau. In concert with what you may already know about camshaft types, selection, and ...

Somewhere there's a perfect balance between peak horsepower, low-speed response, reduced emissions, and something you can afford. Variable valve timing and lift have done their part in getting us all ...

Since the beginning of hot rodding, gearheads have endeavored to increase the performance of internal combustion engines through the optimization of valve timing. It's been proven time after time that ...

Though it's been called many things, the VTEC acronym stands for Variable Valve Timing and Lift Electronic Control. VVTLEC doesn't quite roll off the lips, but the adjectives one tends to spew out ...

The problem is as old as the internal combustion engine itself: Static valve timing is always a compromise. Figures that produce good power at lower engine speeds aren't ideal for higher-rpm operation ...
