ABSTRACT:
Turbo lag is a known impediment of a turbocharged, small displacement engine providing the feel of a large displacement engine. A method of spinning up the exhaust turbine during an interval between the time that the operator moves his/her foot from the brake pedal to the accelerator pedal to initiate a launch. A non-exhaustive list of actions that can be taken to increase exhaust enthalpy provided to the turbine include: opening the throttle, retarding the spark, and closing the wastegate. Additionally, a brake can be applied at one of the vehicle wheels to keep the engine from launching forward during this interval.
