Fletcher, NC: Mahle Motorsports, a division of Mahle the world’s largest piston manufacturer, has introduced a new Elite Sportsman drag racing piston series for popular aftermarket competition big-block Chevrolet cylinder heads.
Using lightweight, strong, true slipper-skirt forgings, Mahle’s emphasis is on power production and durability. By necessity they pay special attention to drag race-specific stress areas, notably skirts and ring lands.
The pistons also feature dual coatings. A phosphate dry-film lubricant is applied to the entire piston followed by MAHLE’s proprietary GRAFAL® coating. Grafal is introduced to the skirts to minimize drag, scuffing, and cylinder bore wear.
Other important considerations include gas porting and an advanced pin bore design as well as the piston’s profile and ovality geometries. Available singly or in packs of eight, with or without rings, and in bore sizes up to 4.630in. (0.030in overbore for 632cu in), the result is a custom-style, high feature piston with off-the-shelf availability.
