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 ...

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.

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 ...

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 ...

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