QR25 Fully Counterweighted and Knife Edged Crankshaft
Regular Price: $1,260.98
Special Price $499.00
QR25 Fully Counterweighted and Knife Edged Crankshaft GEN 1 - QR25DE Will need to be turned/polished (journals)Normally reserved for racing applications, a knife edged crankshaft can help the engine produce more horsepower. Removing this material and bringing it to a sharp edge does a couple of things. First, knife edging can often remove pounds of weight. Less weight equates to a rotating assembly that spins with less resistance, and this in itself is responsible for some gains in horsepower.
The counterweights on a Stock Nissan crank is flat on the ends. As the crankshaft rotates, these counterweights come into direct contact with the engine's oil. This contact creates friction and splashes oil all over the bottom end of the engine. A knifed edged crankshaft actually glides through the oil much easier and encounters far less friction. Anytime friction can be reduced in an engine's rotating assembly or valvetrain, additional horsepower gains are realized. Excellent for turbo or NA applications.
