Powerhaus claims?
From their website:
>>Our special piston crown design utilizes Porsche 962 technology to produce more efficient combustion. Also, PowerHaus racing pistons have pressure fed oiling to the wrist pin, which the factory and Mahle sport pistons do not. Wrist pin and wrist pin bore longevity are thus increased. Further, our pistons have ten inner oil galleys; factory pistons have four. This helps our pistons run cooler and last longer. PowerHaus pistons also have a longer piston skirt to prevent rocking in the event of detonation. RUF "3.4L" (3.369cc) pistons were notorious for being noisy and damaging cylinders because of their short skirt.
A PowerHaus piston assembly (piston, wrist pin & locks, and piston rings) is lighter than a factory assembly, even though it has more compression and a higher crown! The factory 930 7.0:1 assembly weighs 622.5 grams; a PowerHaus racing assembly weighs only 596 grams. This allows the engine to rev up quicker and operate at higher rpm levels with greater ease. <<
