The invention is based on an arrangement of supercharging units (1, 5, 6, 7), which arrangement is to be attached in the construction space of a motor vehicle, for supercharging an internal combustion engine with a fluid (23) comprising charge air and / or exhaust gas, wherein the supercharging units (1, 5, 6, 7) comprise at least one heat exchanger (5, 6, 7) and at least one compressor (1). According to the concept of the invention, the supercharging units (1, 5, 6, 7) are arranged combined in a module (10A, 10B) and, in order for the same to be kept together in the module (10A, 10B), the supercharging units (1, 5, 6, 7) are connected at any rate partially to one another in a fluid-conducting manner, and at least one of the supercharging units (1, 5, 6, 7) is held on a holding structure. This enables the supercharging units to be handled flexibly, simply and nevertheless in a manner saving on construction space and outlay on connection. The invention also leads to a production method.
