The disclosed invention is a storage prebooster which overcomes the characteristic delay in response in turbocharged internal combustion engines when the throttle is opened. The prebooster is used to provide immediate supercharging until the turbocharger begins to develop effective boost. The prebooster is recharged at this point in readiness for future throttle changes. The prebooster can supercharge the engine via a direct connection to the inlet manifold, or it may be used to preemptively accelerate the turbocharger itself in response to the opening of the throttle. A combination of the two preboosting techniques may also be used. The storage prebooster comprises a storage cylinder, a valve for the initial charge and for the re-charging the cylinder, a variable outlet valve and a controller for governing the rate of discharge or preboost during throttle setting changes.
