You've probably read this line a dozen times: "It's never been easier to make horsepower than right now." While that's true, it also means everything else in the engine is now more highly stressed.

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

Q:I have a 327 in my '31 Ford that features nearly the same cam and components as the one you referenced recently in Pit Stop (Nov. '12). Since a 1.6:1-ratio rocker arm will push the valve a little ...

Your doctor will tell you that stress kills. The same is true for high-performance engines and it’s a safe bet that if your engine is running aggressive valvesprings and stud-mounted rockers, there’s ...

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 ...

Key insight: All lift systems target the same physics: reduce mixture density or add head so that nodal balance at the wellbore yields the desired rate. 2.3 Select lift method aligned to fluid, depth, ...
