When rebuilding an engine, there are multitudes of parts to remove, clean, inspect, and potentially replace. A surprising number can often be reused, including the brain of the engine: the camshaft.

How much power can you get from forced induction? Under optimum conditions you can experience as much as a 50 percent increase. However, this is the real world and your numbers are likely to be less.

The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The camshaft position sensor gathers information about ...

Testing. It’s the backbone of hot rodding, and it’s how we separate facts from fiction. It’s also where we generate even more questions, which often results in, you guessed it, more testing. The ...

When the function of a camshaft(s) is explained to non-mechanically-inclined types, it's sometimes referred to as the "brain" of an engine. Most engines will live their entire lives with the stock cam ...

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 ...

Engines are cool. They make noise and lots of power. That's what we're interested in--power. But in order to make that grunt, there are certain things you really should know. For induction and exhaust ...

At its most basic level, an engine is an air pump. Internal combustion engines breathe fresh air and expel wasted exhaust gases to make power. Something has to tell those intake and exhaust valves ...

A British company has developed a digital valvetrain drive system that, it claims, can give petrol engines a diesel-level of efficiency and fuel economy with much lower NOx emissions. The inventors ...
