An inlet tank for a charge cooler comprises a manifold portion, a turbocharger inlet port, and a supercharger inlet port. The turbocharger inlet port is in fluid communication with a compressor wheel of a turbocharger and the manifold portion of the inlet tank. An opening is formed in a sidewall of the turbocharger inlet port. The supercharger inlet port is in fluid communication with an electric supercharger and intersects the turbocharger inlet port. The opening formed in the sidewall of the turbocharger inlet port provides fluid communication between the supercharger inlet port and the turbocharger inlet port. A valve element selectively determines when a flow of air from the supercharger inlet port enters the turbocharger inlet port through the opening based on a pressure differential present between the air exiting the compressor wheel of the turbocharger and the air exiting a compression mechanism of the electric supercharger.
