Have you heard? The old rules about cylinder-head flow are changing. It's not strictly about airflow anymore. If you're serious about making horsepower or at least knowing what the big dogs are doing ...

The art of creating great cylinder heads includes many different things, but a large portion of it comes from lots of time spent with a grinder in hand and in front of a flow bench, determining just ...

All three entries boast jaw-dropping torque and ultra-low emissions, but the innovative architecture, advanced materials and excellent NVH characteristics of Ford’s Power Stroke stand out as ...

The intricacies of airflow dynamics through a cylinder head are some of the most difficult concepts to grasp in all of hot rodding. That made it the perfect topic to discuss in the inaugural ...

Wet flow testing has moved in and out of the realms of mainstream power topics many times during the last 40 years. Like many aspects of race engine development that are a step aside of normally ...

A hemispherical combustion chamber is a type of combustion chamber in a reciprocating internal combustion engine with a domed cylinder head. The hemispherical shape provides a number of advantages ...

The purpose of this work was to develop a high speed flow visualization system which could be used to observe the behavior of the air flow in a steady flow cylinder head assembly. This type of ...
