Abstract: The dual pass intercooled supercharger includes a supercharger and intercooler. The system is configured such that air leaving the supercharger traverses the intercooler from one side to an opposing side two or more times.

Abstract: A cylinder head comprising a single intake valve and at least two exhaust valves per cylinder. The two or more exhaust valves may provide additional curtain area and total cross sectional area for the exhaust flow and better performance for engines equipped with a cylinder head in accordance with the present disclosure.

Abstract: An electronic fuel injection system for land vehicles, comprising: a fuel tank, at least one pump, a fuel sump, wherein the at least one pump is operatively coupled to and between the fuel tank and the sump, and an engine, wherein the engine is operatively coupled to the fuel sump. A fuel sump system for land vehicles, comprising: an inlet from a pump, wherein the pump is operatively connected to a fuel tank, a fuel pump system, a regulator operatively coupled to the fuel pump system, an outlet operatively coupled to an engine, and a float component, coupled to the inlet. An electronic fuel injection system for land vehicles, comprising: a fuel tank, at least one pump, a fuel sump, wherein the at least one pump is operatively coupled to and between the fuel tank and the sump, and an engine, wherein the engine is operatively coupled to the fuel sump and wherein the electronic fuel injection system does not require a return line from the engine to the fuel tank.
