The tough guy in you says to stab that cam in retarded a few degrees for maximum top-end horsepower, while your more practical alter ego suggests advancing it a hair for improved low-end torque and ...

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 ...

Once upon a time, picking a cam for a given engine combo was all about compromise: improve top-end power at the expense of low-end torque, run well at wide-open throttle but sacrifice idle stability ...

Variable valve timing (VVT) and variable valve lift (VVL) have very similar names, both referring to variable valve performance. Does that mean that they are basically the same thing? The are most ...

The jargon goes well beyond just names. Car specs are full of abbreviations that may or may not have any meaning at first glance. And sometimes we get so used to seeing those abbreviations that we may ...

The first production car engine with variable valve timing (VVT) came from Alfa Romeo in 1980. It was installed in the fuel-injected Alfa Romeo Spider. Before this, a few experimental systems existed, ...

Honda did not invent variable valve timing or variable valve lift. In fact, Cadillac had a driver-operated variable valve timing system in production in 1903, three years before Soichiro Honda was ...
