A two-cycle engine for boosting intake pressure for higher performance per displacement. The two-cycle engine includes a crankcase having a blower housing and a crankshaft therein extending through the blower housing. The blower housing has an intake opening and a discharge opening. An impeller is disposed around the crankshaft. At least one cylinder is provided with a corresponding piston therein. The cylinder has an exhaust port located on a side wall of the cylinder. An intake conduit extends along the side wall of the cylinder in a spiral rising towards the top of the cylinder and passing beneath the exhaust port to terminate at a pair of intake ports in the side wall of the cylinder. A boost plenum has an intake tube fluidly connecting the discharge opening of the blower housing to the boost plenum. The boost plenum also has a discharge tube fluidly connecting the boost plenum to the intake conduit.
