Abstract
A twin turbo assembly is provided for an automotive vehicle that includes a first and second air intake for, a first and second turbo charger that includes, but is not limited to a first and second compressor connected to the first air intake, a first and second intake duct connecting the first turbo charger to a combustion engine.A first and second bypass valve is provided to connect the first and second air intake, respectively to the first and second intake duct bypassing the first and second compressor. Overpressure inside the intake ducts can be discharged to a volume between the air filter and the respective compressor. The released pressure prevents or at least reduces the risk that compressed air inside the intake ducts may flow against the first compressor and the second compressor, so that the noise emission associated with this backflow is reduced or even prevented.
