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 ...

The purpose of a cold-air intake is to find cold air in an otherwise hot under-hood environment. It can do this by drawing air from above the hood, under the front bumper or a spot inside the engine ...

Popping the hood of a new Mercedes-Benz 300SL Gullwing must have been quite an experience for most enthusiasts in the Fifties. For starters, the 3.0-liter straight-six sat canted at a fifty degree ...

Optimisation of the intake system in internal combustion engines centres on enhancing the delivery of air (or air–fuel mixtures) to the combustion chamber in order to maximise power, reduce fuel ...

Having a V8 engine does not always guarantee big power. Some, like the early 350-horsepower LS1, are tuned for drivability and usable power delivery, not necessarily outright horsepower performance.

Copying a key design component from Ford, this was supposed to be Pontiac's best high-performance V8 of the '70s, but it turned into a disappointment.

As the horsepower war between automakers in the 1960s forged the Muscle Car era, the need to deliver increased fuel to V8 combustion chambers became evident to engine designers. But without enough ...
