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 ...

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 ...

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 ...

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 ...

Cooling an engine's intake charge is an easy way to make power -- the colder the air, the denser the charge and the more oxygen your engine can mix with fuel to turn into power. This is so important ...

Mercedes is often credited with popularizing the hot-vee engine, but it wasn't the first automaker to put it into production ...

Lexus is synonymous with reliability, but these five engines prove that even the best make mistakes. See which ones suffer from oil sludge and leaks.

Turbochargers and hybrid systems now dominate spec sheets, yet in workshops around the world many veteran mechanics still ...
