A turbocharged engine air supply system for eliminating turbo lag in an internal combustion engine includes an air tank containing a pressurized auxiliary air supply which is used to raise manifold pressure promptly during periods of turbo lag, an air pump connected with the engine crankshaft for filling the air tank with compressed air during deceleration and during other periods of operation when it is not necessary to devote all of the engine torque to the driveline, a first valve for controlling the flow of auxiliary air from the air tank to the engine, and a second valve for recirculating turbocharged air when auxiliary air is being supplied to the engine, thereby allowing the turbocharger to accelerate more quickly.
