A hydraulic assisted turbocharger provides charge air to the intake manifold of a vehicle internal combustion engine. The hydraulic assist can be selectively turned on by the vehicle operator when the vehicle is stopped or is traveling at a low speed so that charge air can be supplied to the engine immediately upon a subsequent acceleration.

Method of controlling an exhaust gas driven turbocharger supplying charge air for an internal combustion engine powering a vehicle, said turbocharger being adjustable from a normal mode to a power mode in which the charge air available to said engine during vehicle acceleration is increased over that available when the turbocharger is in the normal mode, said vehicle including engine power control means switchable by the vehicle operator from a normal mode to a power mode so that the vehicle operator may selectively elect either the normal mode or the power mode, comprising the steps of measuring the speed of said vehicle, permitting the vehicle operator to elect either the power mode or the normal mode for a subsequent vehicle acceleration, and then adjusting said turbocharger to said power mode when the speed of said vehicle is less than a predetermined reference speed and the vehicle operator has elected to power mode to increase the charge air available to said engine and thereby increasing engine power on a subsequent acceleration of said vehicle.
