Stroker kits that range in displacement from 4.5L to 5.0L will offer power/torque increases of 12 to 25 percent, compared to the 50 percent improvement with the Sidewinder Turbo system. Taking all costs into account, the turbo offers a better horsepower-per-dollar value. A turbo system also functions as an altitude compensation device in that it will still give increased density in the cylinder—greater than atmospheric pressure—by providing boosted air when ambient conditions are diminished. A stroker engine cannot offer this benefit as it only deals with barometric pressure.
