Porting an intake manifold essentially helps increase airflow into the engine. Improved airflow equates to more horsepower and helps the engine feel more responsive at the throttle. A standard intake ...

Sometimes theory is neat, but sometimes it fails to describe what actually takes place. The theory of internal combustion engines falls into this category, especially with respect to the function of ...

Editor's Note: As inanimate as intake manifolds may appear, they provide a path to both major and minor on-track power gains. Selection is one thing; "tuning" them to specific applications is a blend ...

Internal combustion engines are fairly simply machines. When you break it down, they are nothing more than air pumps. When it comes to making horsepower and torque, the simple fact is the more air you ...

Given the amount of time and effort that goes into the design of a factory intake manifold, it's not surprising that it's sometimes difficult to improve upon the stock induction system. Stock ...

Your intake manifold. It takes in air and sends it to your engine's combustion chamber. This is basically the start of the combustion process. After all, you can't have combustion without air.

For more than four decades, Lingenfelter Performance Engineering has been churning out a slew of wild high-performance products, from engine upgrades, to parts, to crate engines. Now, the tuner is ...

While just about any internal combustion engine can backfire, older ones tend to be more susceptible to the phenomenon due to ...

In 1959, engines such as the flathead Ford V8, early Oldsmobile OHV V8 and Studebaker Champ six-banger were still sufficiently mainstream in the enthusiast world that it made sense for Edelbrock and ...
