Written by Alfie Bilk September 8, 2014 Mentor, Ohio: Wiseco, the eminent high-performance piston maker established in 1941, is launching a new range of diesel pistons for Dodge Cummins, GM Duramax and Ford Power Stroke engines. Using technology that should make a significant impact in the diesel performance world, the first two piston designs are devoted to Cummins 5.9 liter 12- and 24-valve engines and GM Duramax power units. These will be followed by new designs for Cummins 6.7 liter as well as various Ford Power Stroke models. The chief concern with cast aluminum factory pistons on high-performance diesel engines generating 850 to 1,000hp in street trim, and higher in truck-pulling and diesel drag racing, is premature failure. Alternatively, the shortcoming in high-output diesel engines with standard forged aluminum pistons can be soft, short-lived ring grooves. Wiseco’s solution is Armor Plate™. To the pistons’ most highly stressed areas—chiefly to the bowl, pin bores and ring grooves—Armor Plate adds hardness. In addition, engine building costs are eased, particularly the balancing process, by maintaining piston weights close to those of the original equipment units. Just as impressive is how Wiseco set about creating these new designs, collaborating with specialists in high-level competition. Adept at extracting the utmost from current diesel technology, Wiseco coupled their insight with their own piston-making expertise, which triggered studies of injector patterns and advanced bowl designs. The studies also brought remarkable weight savings for engines with internally balanced crankshafts. Custom units distinguish themselves with weights in the low 600g range, resulting in 30 percent net loss in piston mass, which prolongs crankshaft life by reducing twisting forces....

Written by Sam Logan, September 5, 2014 Last year Mike Androwick’s big-block cylinder head designs won the Northeast Dirt Modified championship. Winner Brett Hearn with over 800 career victories was quick to recommend their virtues: “I’ve never driven a smoother race engine. Better still, it’s effective on any track and under any conditions.” Now on the newsstands, read about Androwick in the September issue of Speedway Illustrated or click here. Note to engine builders: If you are fortunate enough to know Karl Fredrickson, the editor of Speedway Illustrated magazine, you might be reminded of a fundamental taught by your parents: Nothing endures like personal qualities. Conscientious and meticulous in the way in which he runs the magazine, Fredrickson has long maintained a deep commitment to the independent race engine builder. He’s keenly aware that without them the stability of his beloved sport would be greatly jeopardized. Last year, when two races were run in which the rules prohibited OE crate engines, Speedway Illustrated extended a one-year advertising contract to the winning engine builder. This year the magazine is providing a no-charge subscription to your shop. Just forward your name and address in the Comment Box below and you’ll be added to their distribution...
