Forged pistons have been made in the same way for decades, with differences in machining differentiating one supplier’s product from another. But now, a new development called Aligned Grain Flow Technology (AFT) provides a breakthrough for additional strength without additional mass. After several years of experimentation and development by JE Pistons’ Advanced Product Development group,
Piston crown coating is a surprisingly affordable way to increase engine efficiency, horsepower and durability. It’s often said the internal combustion engines, which hold a special love/hate place in our heart, are basically air pumps, and while that’s a useful mental model when considering many aspects of how they operate, it’s more accurate to say
Piston design used to be a tedious process: pen had to be laid to paper, mathematical equations required solutions and other processes needed to be completed before a single tool could be touched.
As long as there have been forged pistons, there has been the problematic phenomenon of piston slap. However, a new, solid-film-lubricant coating is changing that up. The revolutionary, patented technology– including the formula, tooling, and application process – was developed in-house to eliminate piston slap.
Freshening an engine has always been a game of careful disassembly and evaluating the components for wear followed by a series of judgment calls that balance the cost of new parts against further pushing the veterans. Evaluating pistons takes a practiced eye, but there are several checking points that any engine builder can use to
The classic Hollywood line is you can’t be too rich or too thin. While full-figured starlets may now be finding favor in tinsel town, the too-thin line is still in vogue when it comes to piston rings. It wasn’t all that long ago when state of the art racing piston ring thicknesses hovered between 1/16-inch
Captain Kirk in the now-classic Star Trek TV series was constantly badgering poor Scotty for “More power!” That’s what everybody wants. More power! One way to ensure the horsepower built into your engine is achieved is to seize every opportunity to seal that cylinder pressure on the push side of the pistons.
JE Pistons stocks thousands of pistons in what is called the shelf stock program; each of which has been built for a high-volume application, such as those pistons built for a traditional small-block Chevrolet engines.
