After witnessing Dart Machinery's custom-built wet-flow test bench in action, we couldn't get back here fast enough to write about it. This is the future of cylinder-head development, and Dart is ...

A flow bench test is done at a fixed test pressure ... heating and cooling that occurs during blow-down and the pumping loop. Threaded wand probes can be inserted in the port to visually display ...

This is when Joe Mondello's innovative wet flow bench hit the headlines. Wet flow testing is far from complicated, but, like most things, if not done right it can be mostly meaningless.

The flow loop is one of only a handful of its kind available for industry research, development and testing and will play a central role in an ongoing SwRI project to reduce methane emissions.
