JE Introduces Revolutionary New Perfect Skirt Coating

JE Pistons has introduced a revolutionary new, solid-film-lubricant coating called Perfect Skirt. The patented technology—including the formula, tooling, and application process—was developed in-house and eliminates piston slap and false knock.

“The motivation was to develop a robust skirt coating that could be applied and bonded thicker and allow the forged piston to be installed at the same or less cold clearance than a cast piston, as measured on the coating,” says Nick DiBlasi, product manager at JE Pistons.

Perfect Skirt is a solvent-based coating that is permanently applied to the piston skirts in a 3-stage bonding process. Unlike many coatings, it is not a temporary layer for break-in. It will stay bonded to the piston through its service life. “This is not a typical spray-on type application,” says DiBlasi. “The skirt panels are transformed from a bare aluminum running surface to a permanently bonded solid-film running surface.”

Perfect Skirt will complement JE’s other well-known skirt coating called Tuff Skirt—which is typically is used on custom orders where the numerous options available change the piston foundation too much to allow proper application of the coating.

“Perfect Skirt requires tooling designed to fit each piston family and is used on our catalog shelf part line, which we designed specifically for it,” explains. DiBlasi.

The new coating from JE is unique in that the material is applied to a specific thickness that reduces the running clearance of the piston inside the cylinder. However, don’t be misled into thinking that JE simply applies a thicker layer of standard skirt coating.

“The Perfect Skirt coating formulation has the unique ability to automatically and precisely fit itself to the specific cylinder in which it’s installed,” says DiBlasi.

When an engine is first fired up, the piston coating in contact with the cylinder wall will quickly adjust to a precise form and provide minimum running clearance. “At this point, the coating has settled into a uniform and equalized pattern, providing very low friction and quiet operation throughout its service life,” adds DiBlasi. By reducing clearances, the Perfect Skirt coating reduces cold-start wear and more importantly the chance of false knock readings in late-model engines.

2018 Lamborghini Aventador S Roadster Review

“Supercars just don’t excite me anymore.” These words, spoken to me over a month ago by another journalist, friend, and (so-called) enthusiast were echoing in my head for far too long, but they’ve finally been drowned out. Drowned out by the wail of a naturally aspirated 6.5-liter V12 engine mounted in the middle of the new Lamborghini Aventador S Roadster. My friend’s point is that back in the good old days, there was a crop of supercars that captured the imagination with amazing style, sounds, performance, and more. Today, it seems like everything is capable of supercar performance, with large luxury sedans outdoing some of the best and most dedicated teams of car nuts, while former pillars of automotive excellence are suddenly pumping out family-friendly SUVs. Beyond that, another league of supercars, dubbed hypercars have cropped up with hybrid gas-electric powertrains that make magical things happen quickly, but at the cost of the acoustic drama, visual flair, and engag...

Project SportWagen: Going Stage 2 with APR

    When we last left you, the humble little SportWagen was fresh from the development process with our friends at AWE Tuning, sporting a new downpipe, exhaust and intake, allowing things to breathe a bit easier.  The car sounded great, but there was no getting around the fact that our wagon was still quite, well, slow.   While we realize that nothing we do to the Golf SportWagen at this point will make it a race car, we still felt compelled to do something .  To put it bluntly, we had a fever, and the only cure was more power. Flash forward a few hours, and we found ourselves at Waterfest, staring down APR’s palatial spread and the numerous tuned vehicles surrounding it.  Earlier in the year, APR had hinted to us that their 1.8 TSI files would be quite impressive, and based on what they were able to do with the 2.0 TSI found in the new GTI and our time in their Golf R, we knew it’d be worth the wait.  So with this in mind, we lined our G...

Project Golf SportWagen- Intro

I’ve never really been one for SUVs and crossovers.  The current offerings aren’t the body-on-frame, go-anywhere specialty tools I remember from my youth, and what they lack in capability, they also lack in on-road performance. The current crop isn’t terribly good at handling or being efficient, which in my opinion are major components of our ideal driving experience.  So when it comes to space or utility, I usually look for something of the wagon variety- and it seems that I’m not alone. We hit quite a few shows around the east coast each summer, and we see modified Jetta SportWagens at nearly every event. Even amongst common consumers, these cars are highly sought-after. They don’t depreciate much, making even early Mk 5 2.5 versions expensive in comparison to other Jettas or Golfs of the same vintage. This year, Volkswagen launched their latest SportWagen, which is now billed as a Golf.  In many ways, this latest SportWagen is the best yet and it has certai...
