The APR crankshaft gear increases power and torque by increasing the speed of the compressor. In order to be able to process the additional pressure, however, a change in engine management is required, ie the APR Stage 2 which is absolutely necessary.
The crankshaft sprocket increases the diameter of the standard pulley from 162 mm to 187 mm, which causes the compressor to spin approximately 15.4% faster. This leads to a significant increase in horsepower and torque over the entire speed range. The APR crankshaft sprocket is balanced to factory specifications and also has the screw entries in the same location. The wheel is CNC machined from lightweight aluminum with weight-saving milled grooves. It has an anodized black surface and comes with new screws.
