Piston Weight Difference at Steve Huckabee blog

Piston Weight Difference. Aluminum just does not weigh. From what i've seen, the difference in the piston weight is usually close to the correction about needed on the crank. You need to keep in mind that the piston weights are only factored into the reciprocating mass at 50% total weight. Heaviest unit combined with the lightest pins/rings/clips came in at. It is virtually impossible to take 12 grams of weight out of a piston without seriously weakening it. The box weight and what the original balance job has for the pistons is 583 grams (without pin). Reducing the rotating mass within the engine and throughout the driveline does help performance, but not by any huge amounts. If the mass of the counterweight equals the weight of the upper half of the rod, piston, wrist pin and rings, the forces will be balanced and the engine will run smoothly. Some racers deliberately overbalance for high rpm usage, figuring the momentum of the fast moving piston and rod is.
