MAHLE Motorsport, the leader in piston technology loads every piston with features that win races and championships year after year. Through research and development partnerships with the OEM’s, as well as NASCAR and Formula 1 race teams, MAHLE is constantly discovering new technologies that are incorporated into every piston we make. As a result, we’ve been able to introduce features like Finish Machined Pin Bores, Ultra Flat Ring Grooves, Slipper Skirt Forgings, and Grafal® Skirt Coatings. Here’s why they are so important:
Finish Machined Pin Bores
Piston failures can often be traced back to poor and inconsistent pin bore quality or design. The pin bores on every MAHLE Motorsport piston are finish machined using CNC equipment specially designed and manufactured by MAHLE to precisely control shape, size and alignment. This added control allows for advanced designs and flexibility, resulting in unmatched consistency and performance.
Every MAHLE Motorsport piston is machined to exacting tolerances with focused attention given to the radial flatness of the ring grooves. A flat ring groove is essential in achieving and maintaining the best seal possible. The quality of the ring grooves is so critical to peak and lasting performance, that MAHLE designed and built the machinery used to machine the ring grooves for its Motorsports piston assemblies. Combined with ultra flat MAHLE rings that are included in every PowerPak piston kit, MAHLE delivers the formula for the best sealing power cell on the market.
Slipper Skirt Forgings
MAHLE uses strong, lightweight, low drag forgings in every PowerPak piston kit. Not all piston manufacturers can make that claim. A Slipper Skirt forging offers many benefits over the standard “Full Round”design, but the technology runs much deeper than looks alone. These benefits are only achieved through the proper management of the design; any misapplication can result in a similar looking part with poor performance.
Grafal Skirt Coatings
MAHLE’s proprietary Grafal® anti-friction skirt coating is like no other on the market. It is graphite impregnated to reduce drag like many other skirt coatings, but this is where the similarities end. The screen print application provides superior adhesion and is designed to last 100,000+ miles. Because Grafal® is a compressible membrane with a unique cushioning property, harsh contact between the piston skirt and the bore is dramatically reduced. This results in much less wear on the bore and significantly reduces piston skirt fatigue.
MAHLE’s continued search for new and better technologies consistently keeps our customers in the winner’s circle. For details on many of the race winning features of a MAHLE Motorsport piston visit www.mahlemotorsports.com. Or call 1-888-255-1942
