It's a well-known fact that piston ring gaps represent an area of pressure loss in a running engine. It has been found that minimizing end gap under operating conditions offers a measurable power ...

High performance engine building is the art of attention to detail. Top engine builders don’t take anything for granted. John Bouchard, engine builder at Boost Addicts in Madison, Tennessee showed us ...

But when done right, piston rings can create a power advantage by maximizing dynamic engine compression while still maintaining good oil control. This involves both proper selection for the intended ...

No matter how much we love them, our engines are still basically inefficient air pumps and need all the help they can get to make power. Like any other type of pump, if it leaks, it won't work. And ...
