MAHLE’s relationship with Porsche dates back to Porsche’s beginning.
Together we have developed some of the best competition and sports car engines available throughout the last nine decades.
The pistons are machined from forgings with narrower and shorter skirts to reduce weight and friction. They are then dual coated, with Phosphate and MAHLE’s proprietary Grafal® skirt coating. The phosphate is a dry film lubricant designed to help protect the pin bores from galling and ring grooves from micro-welding. The Grafal® anti-friction skirt coating is designed to reduce drag, wear and noise. The kits are supplied with modern ring sets made from stronger more durable materials that are dimensionally narrower and shorter to be more conformable providing more consistent contact with the cylinders resulting in increased sealing and oil control.
The cylinders included in Motorsports air-cooled kits are produced and machined to original equipment tolerances, designed to provide increased performance, durability and longevity. Some applications are available as either a slip-in or machine-in design. The slip-in cylinders are simply a larger internal bore replacement. The machine-in cylinders require the engine cases be machined to a larger bore diameter to accept their larger spigot diameter. The larger spigot diameter is preferable for extreme applications as with highly boosted turbo or competition use engines.
