Abstract: The portable engine starter for vehicle racing may be an electromechanical structure configured for use with an engine in a vehicle. As a non-limiting example, the engine may be a combustion engine. The portable engine starter may detachably couple to the engine and may be operable to start the engine. The rotation of a starting motor located within the portable engine starter may provide the motive forces used to start the engine in the vehicle. The portable engine starter may be an independently powered structure. The portable engine starter may include a housing, the starting motor, and a power circuit. The housing may enclose the starting motor and the power circuit. The power circuit may electrically connect to the starting motor. The portable engine starter may be detached from the vehicle once the engine of the vehicle is started.
