The piston skirt and pin account for about 17 percent of the frictional loss in a combustion engine as they are the most difficult to keep lubricated and have the largest contact surfaces. Federal ...

If the engine builder recorded the original piston diameter, a simple comparison will reveal any changes. It’s possible to see pistons with partially collapsed skirts from detonation or physical ...

Pistons Turn Your Engine's Linear Motion Into Rotary Motion. HOT ROD Staff Writer Aug 04, 2006. See All 19 Photos. Here are the three basic piston types: (from left to right) cast, hypereutectic ...

Despite their simple appearance, there’s quite a bit of technology built into a modern performance piston, such as the moly-based skirt coatings that reduce skirt scuffing on these Speed-Pro ...

We recommend .005-inch clearance with our threaded buttress design, and .006-.008-inch on a ground skirt. Piston-to-wall clearance is best based on mass expansion and factors such as pin boss ...

The key differentiator for the Magnum, however, is its unique “double-band” piston skirt design-a first for modern diesel pistons. The double-band skirt helps to reduce frictional drag and ...

Federal-Mogul developed the Magnum piston at its Powertrain Energy technical center in Plymouth, Mich. -- one of the company's 18 globally networked technical centers. More info: www.federalmogul.com.

While recessing piston skirts around the wrist pin bores is nothing new when it comes to high-performance rotating assemblies, the increased length of the pill-shaped pistons could net a greater ...

The company has only developed the rods as drop-in replacements for 5.3- and 6.2-liter LS V8 engines from General Motors thus far. In its own testing, Transcend says it was able to tune the 5.3 to ...
