Forged Parts #lesson A piston is a component in the engine that compresses gases upon ignition, then takes the transfer force of that ever-expanding gases to the crankshaft of the engine. With 4-8(and in very high-end engines, 16) pistons working in unison, make something called horsepower. Horsepower is something that is transfered through the transmission to turn your wheel. Well, what happens when you produce too much of this horsepower in the engine? Regular aluminum-alloy pistons are strong enough to take the power produced by any everyday engine and in a lot of cases budget streetcars. If you have too much power being produced(literally too much bang in the cylinders) then a component called a “piston rod” will literally break in half, destroying your engine and your dreams. That’s where forged components come in. Forged pistons, or a, “Hypereutectic piston” is the result of addive silicon and forging of the part, over them just being casted. This in turn makes them stronger, with them still being lightweight as a normal piston. The only downturn of getting these parts is the price tag, as you have to buy them from specialty shops. The cost of the item will be most definitely worth it in the end, because you wouldn’t want your hopes and dreams bursting into flames before your very eyes!
